BACKGROUND OF THE INVENTION
The present invention relates, in general, to timer picture recording by a
picture recording apparatus (in the present invention, a video tape
recorder (VTR) will hereinafter be described as an example of the picture
recording apparatus), and more particularly to the picture recording
control of a television receiver (hereinafter, referred to as "a
television" for short, when applicable) which has a function of commanding
the VTR to record a scene on a video tape so that in accordance with the
picture recording command issued from the television, the VTR records
automatically a scene on a video tape.
Heretofore, in the case where a desired channel of a television was
subjected to the timer picture recording by a VTR, on the VTR side, the
timer picture recording was performed on the basis of the picture
recording reserve. As for the public known example relating thereto, there
is JP-A-1-212096.
In the above-mentioned prior art, for example, in the case where a desired
broadcasting via satellite (hereinafter, referred to as "a BS" for short,
when applicable) channel was intended to be subjected to the picture
recording by a VTR which did not contain a BS tuner, it was necessary that
the video and sound signals, relating to,the desired BS channel, output
from the television containing a BS tuner were connected to an external
input terminal of the VTR so that the timer picture recording was
performed on the VTR side. As for the method in this case, there are known
(1) a method in which the desired channel is fixed so that the picture
recording channel is not changed by mistake by the operation for selecting
a television broadcast (i.e., a broadcasting TV station), and under this
condition, the picture recording is performed by the VTR, (2) a method in
which the television is provided with the same function of reserving a
program as that of the VTR and the picture recording is performed with the
television synchronized with the VTR, (3) a method in which the channels
of the television are controlled on the VTR side by the wired control bus,
thereby performing the timer picture recording, and so forth. With respect
to the method (1), since the picture recording channel is fixed, only one
channel can be subjected to the reserve of the picture recording. With
respect to the method (2), the program reserve needs to be performed on
the television side and the VTR side, respectively. Therefore, there
arises the problem that the reserve operation takes a great deal of time,
and also the malsetting readily occurs such that the reserved recording
contents are different from each other. In addition, with respect to the
method (3), the realization can be readily performed if the maker of the
television is the same as that, of the VTR. In the case where the maker of
the television is different from that of the VTR, however, there arises
the problem that it is difficult to standardize the communication
procedures between the different makers.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a television
receiver which enables readily the timer picture recording even in the
case where the maker of a television is different from that of a VTR.
In order to attain the above-mentioned object, a television is provided, in
addition to a program reserve facility for reserving and executing a
desired channel at a desired time, a picture recording reserve facility
for performing the control so as to record the desired channel in an
external picture recording apparatus such as a VTR, and with respect to
the execution of the picture recording reserve by the external picture
recording apparatus such as a VTR, a command for selecting, if it becomes
a predetermined time, the channel which is previously reserved to set a
recording mode is transmitted from the television to the external picture
recording apparatus such as a VTR through a transmission line which is
constituted by a wire or a wireless channel such as infrared rays and is
provided between the television and the external picture recording
apparatus such as a VTR, whereby the above-mentioned problems associated
with the prior art are solved.
In recent years, the remocon device utilizing the infrared rays has been
widely popularized in all the electronic apparatuses, in particular in the
household electronic apparatuses. To the television and the VTR, such a
remocon device has been widely applied as if considered as its typical
example. The present invention is constructed in such a way that the
remocon codes of the VTR are stored in the inside of the television so
that the channel which is intended to be picture-recorded can be subjected
to the picture recording reserve at a desired time on the television side,
and for the television, a remocon signal generator is prepared which
operates to generate infrared ray remocon signals to the VTR in accordance
with the stored remocon codes of the VTR, and when it becomes time to
start the picture recording which is previously reserved, the remocon
codes for turning a power supply on, selecting a television broadcast and
recording a scene on a video tape are transmitted from the television to
the VTR through the remocon signal generator, and when it becomes time to
end the picture recording, the remocon codes for stopping the picture
recording and turning the power supply off are transmitted, whereby the
VTR performs the picture recording in accordance with those remocon codes
supplied from the television, that is, the VTR receives the remocon codes
supplied from the television to a remocon receiver contained in the VTR
itself, and operates to perform the picture recording just as if a user
instructs a remocon device for the VTR to perform the picture recording.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is a schematic view showing a structure of a system, for controlling
the picture recording in a VTR from the television side, of an embodiment
according to the present invention. The example shown in the figure shows
a case where on the basis of the assumption of the typical state of
installation of both a television and a VTR in a home, a television 1 is
placed on a television base 26 and a VTR 18 is accommodated in the
television base 26. To the television 1, a remocon portion 22 for emitting
the infrared rays which is mounted to an end portion of a connection cable
21 is connected through the connection cable 21. In the example shown in
the figure, the remocon infrared ray emitting portion 22 is arranged in
the television base 26 so as to be near a remocon light receiving portion
19 of the VTR 18. While what kind of a signal the remocon infrared ray
emitting portion 22 outputs will be described in detail later, the remocon
light receiving portion 19 of the VTR 18 detects the infrared ray signal
supplied from the remocon infrared ray emitting portion 22 so that the
control of the picture recording in the VTR 18 is performed.
FIG. 2 is a cross sectional view showing an example of the inside of the
remocon infrared ray emitting portion 22 shown in FIG. 1. Infrared ray
emitting diodes 23a and 23b are provided in the hemispherical remocon
infrared ray emitting portion 22. In this connection, the infrared ray
emitting diodes 23a and 23b are arranged in such a way that the light
emission axes intersect each other so as to reduce the directivity and to
radiate the infrared rays spreadably in the wide range. In addition, if a
fixing member 22a such as a magnet is, as shown in FIG. 2, mounted to the
bottom surface of the remocon infrared ray emitting portion 22 so as to
enable the portion 22 to be fixed to the television base 26 or the cover
of the VTR 18, the management thereof will be convenient.
FIG. 3 is a circuit diagram showing a configuration of an internal circuit
of the remocon infrared ray emitting portion 22. This example is an
example wherein in the remocon infrared ray emitting portion 22, the
infrared ray emitting diodes 23a and 23b are connected in series with each
other. However, even if the relative positional relationship between the
infrared ray receiving portion 19 of the VTR 18 and the remocon infrared
ray emitting portion 22 should be changed, the enough emission output to
enable the VTR to operate has only to be obtained. From this viewpoint,
the circuit configuration of the remocon infrared ray emitting portion 22
is not limited to the configuration shown in FIG. 3.
In FIG. 1, the other end of the connection cable 21 to one end of which the
remocon infrared ray emitting portion 22 is mounted is connected to the
television 1. However, since the connection cable 21 extends necessarily
between the inside and the outside of the television base 26, it is more
convenient that the other end of the connection cable 21, which is to be
connected to the television 1, is detachable.
FIG. 4 is a view of an example showing only a portion relating to the
present invention with respect to the connection between the television 1
and the VTR 18. In the case where the VTR 18 does not contain a BS tuner,
the television 1 includes a BS output terminal 15 for supplying the video
signal and the sound signal which have been obtained by the demodulation
in a BS tuner contained in the television 1 after the reception of the
input signal to the VTR 18, and the output of the BS output terminal 15 is
connected to an external input terminal 17 of the VTR 18 through a
connection cable 24 so that the video signal and the sound signal of the
selected BS channel are supplied to the VTR 18.
The VTR 18 which can be operated by the infrared ray remocon is an object
of the present invention and includes a remocon light receiving portion 19
having an infrared ray receiving photodiode 20 for receiving an infrared
ray signal supplied from a remocon transmitter (not shown in FIG. 4) of
the VTR 18 itself. Therefore, when the remocon codes of the VTR 18 are
previously stored in the television 1, and the codes corresponding to the
power source on, the channel selection, the picture recording and the like
are modulated with a predetermined frequency to be output as a remocon
signal to a picture recording control output terminal 16, the infrared ray
remocon signal is generated by the remocon infrared ray emitting portion
22 and then is received by the remocon light receiving portion 19, thereby
performing the remote control. That is, the VTR 18 is operated by the
remocon transmitter (not shown) contained in the VTR 18 itself and also is
controlled by a control signal output from the television 1. In this case,
if a wavelength of the infrared rays, which are emitted from the remocon
infrared ray emitting portion 22, is approximately equal to that of the
infrared rays which are emitted from the remocon transmitter of the VTR 18
itself, the transmission efficiency will be increased and the operation
will be performed in a preferable manner even under the condition of the
low power.
FIG. 5 shows an internal configuration of the television 1. In the figure,
from an input signal which has been received by a VHF/UHF antenna 2, a
video signal and a sound signal of a desired V/U channel are obtained
through a V/U tuner 3 which has the function of detecting and amplifying a
signal having an intermediate frequency. On the other hand, an input
signal of a desired BS channel which has been received by a BS antenna 4
is converted into a signal having an intermediate frequency of about 1 GHz
by a converter contained in the BS antenna 4 and then is input to a BS
tuner 5 which has the function of detecting and amplifying a signal having
an intermediate frequency, thereby obtaining a video signal and a sound
signal of the desired BS channel. The video signal and the sound signal of
the V/U channel and those of the BS channel are respectively input to a
circuit 6 for switching a signal. From the signal switching circuit 6, the
video signal and the sound signal of the BS channel are supplied to a BS
output terminal 15, and the video signal is supplied to a circuit 10 for
processing a signal. Then, the signal processing circuit 10 separates the
video signal supplied from the signal switching circuit 6 into a luminance
signal, a chrominance signal, a synchronous signal and the like and also
superimposes a picture display signal supplied from a picture display
circuit 7 on the video signal consisting of the luminance signal and the
chrominance signal to display the resultant signal on a cathode ray tube
11. The picture display circuit 7 contains, in order to display the
information relating to the channel number, the contents of the picture
recording reserve, and the like on the cathode ray tube 11, a character
generator and supplies the picture display signal consisting of R, G, B
and a blanking signal to the signal processing circuit 10. A circuit 14
for generating a picture recording control signal is controlled on the
basis of a serial control data including the information relating to a
control command and a channel number by a main microcontroller 8. The
picture recording control signal is converted into a remocon signal train
which has been produced on the basis of the serial control data to be
output from a picture recording control signal output terminal 16. A
memory circuit 9 stores the channel information relating to the receivable
channel number and the like, and the reserve information relating to a
picture recording start time, a picture recording end time, a picture
recording channel and the like and is also used as a backup memory when an
AC power source is cut off due to the service interruption. The main
microcontroller 8 is connected to the V/U tuner 3, the BS tuner 5, the
signal switching circuit 6, the picture display circuit 7, the picture
recording control signal generating circuit 14, the memory circuit 9 and a
remocon light receiving circuit 12 contained in the television 1 itself to
control those circuits. The remocon light receiving circuit 12 of the
television 1 itself includes a photodiode 13 for receiving the infrared
rays to convert an infrared ray remocon signal into a remocon signal as an
electric signal. The remocon signal which has been output from the remocon
light receiving circuit 12 of the television 1 itself is decorded by the
main microcontroller 8 so that the selection of the channel, and the
setting, correction or cancellation of the contents of the picture
recording reserve which are displayed on the cathode ray tube 11 are
performed.
FIG. 6 shows an internal configuration of the picture recording control
signal generating circuit 14. In the figure, the remocon codes
corresponding to the functions of the VTR 18 as shown in FIG. 12 are
stored in a memory area 14g in a submicrocontroller 14a, and thus the
remocon signal can be output which has been obtained by modulating the
carrier, which is previously determined on the basis of the serial control
data from the main microcontroller 8 with the desired remocon code. The
remocon signal thus output is connected to a base terminal of a drive
transistor 14c which operates to drive the infrared ray emitting diode 23
through a resistor 14b. Resistors 14d and 14e operate to limit the drive
current for the infrared ray emitting diode 23, and a resistor 14f
operates to prevent the recovery time (the rise time) when the drive
transistor 14c is turned off due to the floating capacity of the
connection cable 21 from being delayed. In addition, a jack 16a is a jack
portion of the picture recording control output terminal 16 in which a
miniplug connected to the end portion of the remocon infrared ray emitting
portion 22 is plugged, and also is detached therefrom when both the
television 1 and the VTR 18 are installed as described above and the
remocon infrared ray emitting portion 22 is unnecessary.
FIG. 7 is a schematic diagram of a remocon transmitter 25 showing only
minimum keys relating to the present embodiment. In the figure, the
reference numeral 25a designates a reserve key for commanding the reserve,
the reference numeral 25b designates a test key for testing whether or not
the picture recording channel commanded to the VTR 18 is proper, the
reference numerals 25c to 25l designate ten keys which correspond to the
numerals 0 to 9, respectively and are used to input the desired numeral or
numerals and to select the channel in the reserve operation, and the
reference numeral 25m designates a cursor key for moving the selected
position in the menu picture, the reserve setting or the reserve contents
displayed on the cathode ray tube 11 in all directions.
FIG. 13 shows an example of the contents of the reserve setting which are
displayed on the cathode ray tube 11 of the television 1. When the reserve
key 25a is pressed down with the remocon transmitter 25 of the television
1 directed to the infrared ray receiving portion of the television 1, the
main microcontroller 8 commands the picture display circuit 7 to display
the reserve picture for the reserve setting as shown in FIG. 13(1). Then,
by pressing down the right and left portions of the cursor key 25m, it is
selected whether the desired reserve is the program reserve as the reserve
only in the television 1 or the picture recording reserve by which the
scene is to be recorded in the VTR 18. If the picture recording reserve is
selected, the screen of the television 1 shows the contents of FIG. 13(2),
and the assignment of the date to be reserved as the next item is waited.
In this connection, in FIG. 13(2), there is shown an example in the case
where the picture recording reserve is selected and the characters of
"Program Reserve" are erased. However, in this case, alternatively, the
method may also be adopted such that without erase of the characters of
"Program Reserve", the characters of "Recording Reserve" are left by using
the different color or are flashed. When in FIG. 13(2), the date to be
reserved is input using the ten keys 25c to 25l, the screen of the
television 1 shows the contents of FIG. 13(3), and the input of the
reserve start time is waited. In such a way, when the input of all the
necessary items such as the end time and the channel to be selected has
been completed, all the items thus input are displayed as shown in FIG.
13(6), and then if the reserve key 25a is pressed down again, the reserve
operation will be completed.
While in the above-mentioned example, a user inputs the reserve items one
item by one item, such an input method is troublesome because of the
multiple input items, and in addition thereto, there is a suspicion that
the operation is difficult. In recent years, the method employing the bar
code and the simple method called the G code produced by Gemstar Co. Ltd.
in which the date, the channel, the picture recording start time, the
picture recording end time and the like are collectively coded in the form
of a numeral having some figures, and the resultant numeral is input to
perform the reserve have been adopted in many cases, and such codes have
appeared in the program column of the newspapers and the magazines in many
cases. If that G code method is employed, the reserve can be more simply
performed. FIG. 14 shows an example of the picture in the case where the G
code method is employed. The contents shown in FIG. 14(1) are displayed in
the same manner as that in those of FIG. 13(1) when pressing down the
reserve key 25a. Then, when the picture recording reserve is selected
using the cursor key 25m, the characters of "Recording Reserve" are, as
shown in FIG. 14(2), displayed with the color of those characters changed
(shown by the hatching in the figure), and thus the display for urging the
input of the reserve code called the G code is performed. When the user
reads out the desired reserve code from the program column of the
newspaper or the magazine to input the reserve code thus read, the screen
of the television 1 shows the contents of FIG. 14(3). Then, when pressing
down the reserve key 25a again, the main microcontroller 8 decodes the
numeral thus input into the data relating to the date, the channel, the
picture recording start time and the picture recording end time, thereby
displaying a reserve table as shown in FIG. 9. In the figure, No. 1 shows
the reserve contents which have already been reserved, and the contents
which is newly reserved at this time are displayed in No. 2. In this
connection, "Program" and "Recording" which are displayed below "Reserve"
represent "Program Reserve" and "Recording Reserve", respectively, the
numeral which is displayed below "CH" represents the reserved channel, and
"V" which is displayed beside that numeral represents that the reserved
channel was selected by the VTR 18. FIG. 9 shows an example of the table.
In this connection, as long as it is possible to discriminate whether the
desired reserve is "Program Reserve" or "Recording Reserve" and whether
the channel of interest is the channel of the television 1 or the channel
of the VTR 18, even if other methods are employed, there is no problem.
Referring back to FIG. 1, an LED 27 which is provided in a lower position
of the front face of the television 1 is an LED which emits the rays in
order to distinguish whether the reserved contents of the television 1 is
the program reserve or the picture recording reserve of the VTR 18. The
LED 27 emits the green rays in the program reserve and emits the red rays
in the picture recording reserve. In such a way, a distinction between the
program reserve and the picture recording reserve is performed. In the
case where a plurality of reserve was performed, both the program reserve
and the picture recording reserve may be set at the same time in some
cases. However, at that time, the LED 27 serves to display the picture
recording reserve top priority and as a result the LED 27 emits the red
rays. The remocon transmitter 25 for TV is operated so as to be directed
to the infrared ray receiving portion 12 of the television 1 and thus
operates to select the channel of the television 1, and set, correct or
cancel the contents of the program reserve and the picture recording
reserve which are displayed on the cathode ray tube 11.
Next, the execution of the reserve will hereinbelow be described. Assuming
that the present date is 15, when it becomes AM 8:00, since the program
reserve is previously set, the main microcontroller 8 turns the power
source of the television 1 on (but, when the power supply has already been
turned on, the state is not changed) and controls the V/U tuner 3 to
select Channel 12. If no key operation by the remocon transmitter 25 is
performed until the end time, the main microcontroller 8 operates to turn
the power source off at the end time of AM 9:00. When it becomes PM 11:00,
since the picture recording reserve is previously set, the main
microcontroller 8 supplies the maker code which is previously selected on
the basis of the menu picture, and the control signals for the power
source, CH and the picture recording command to the submicrocontroller
14a. Then, the submicrocontroller 14a outputs the power source command,
the CH command and the picture recording command which are set as shown in
FIG. 10(A) from the remocon infrared ray emitting portion 22. When it
becomes the end time of PM 11:30, likewise, the stop command and the power
source command are output, thereby completing the timer picture recording.
With respect to the timing when the commands shown in FIG. 10(A) are
issued, if the REC command is issued slightly before the picture recording
start time and also the stop command is issued slightly after the picture
recording end time, the difference between the time in the broadcasting
station and that in the timer contained in the television 1 can be
absorbed, and also the picture recording of the desired channel is
performed rightly. It is, of course, to be understood that both the power
source command and the CH command for starting the reserve should be
issued before the issue of the picture recording command, and at the time
point when the REC command is issued, the VTR should be in the state in
which the picture recording can be performed, and also the power source
command for turning the power source off should be issued after the issue
of the stop command.
Now, in response to the power source command, normally, the power source of
the VTR may perform the operation in which the state is inverted every
reception of the command, the so-called "the toggle operation" in many
cases. In such cases, in response to the power source command, the state
of the VTR may become unstable in some cases. Therefore, the single
command for turning the power source on or off is previously set so as to
be issued prior to the toggle command. In addition, in the case where only
the toggle command is issued, in the state in which the picture recording
is set, the power source of the VTR is previously turned off, whereby it
is possible to cope therewith.
With respect to the picture recording reserve of the BS channel, the
operation depends on whether or not the BS tuner is contained in the VTR
18. The information relating to whether or not the VTR 18 used contains
the BS tuner is, together with the remocon code table shown in FIG. 12,
previously stored in the memory provided in the picture recording control
signal generating circuit 14 of the television 1, or in the memory circuit
9 by the user. As a result, it is possible to judge whether the tuner of
the television 1 or the tuner of the VTR 18 is used in the picture
recording reserve. In the case where the VTR 18 contains the BS tuner, "V"
can be displayed in the item of CH shown in FIG. 9. On the other hand, in
the case where the VTR 18 does not contain the BS tuner, "V" can not be
displayed.
The execution of the picture recording in the case where the VTR 18
contains the BS tuner is performed in such a way that the commands shown
in FIG. 10(A) are output from the remocon infrared ray emitting portion 22
in a similar manner to that in the picture recording reserve by the
above-mentioned V/U tuner. On the other hand, in the case where the VTR 18
does not contain the BS tuner, the commands shown in FIG. 10(B) are output
from the remocon infrared ray emitting portion 22, thereby executing the
picture recording reserve. In this case, since for the reserve, "V" is not
displayed in the item of CH in the screen of the television 1, the desired
channel is selected by the BS tuner 5 and then the video signal and the
sound signal are output to the terminal 15. The difference between the
contents of FIG. 10(A) and those of FIG. 10(B) is that the CH command in
FIG. 10(A) is replaced with the external input command in FIG. 10(B). Out
of various types, there are some types in which even if the VTR 18
receives the external input command from the remocon infrared ray emitting
portion 22, it is impossible to select the external input. In this case,
it is necessary that the input to the VTR 18 is previously made the
external input by the user. If the VTR 18 receives the external input
command, since the input of the picture recording signal is switched over
to the video signal and the sound signal of the selected BS channel which
are output to the terminal 15 of the television 1, the reverse picture
recording of the desired BS channel can be performed.
Now, the signals which are output from the remocon infrared ray emitting
portion 22 are signals which are obtained by modulating the carrier having
a predetermined frequency with the remocon codes corresponding to the
individual commands. This is as shown in FIG. 11. FIG. 11(A) shows the
remocon code signal, and FIG. 11(B) shows the infrared ray remocon signal
which is obtained by modulating the carrier having a predetermined
frequency with the remocon code signal of FIG. 11(A). In FIG. 11(A), there
are shown the header representing the beginning of a series of data, the
code called "the custom code" which is determined every maker or type, and
the subsequent data code corresponding to the remocon function shown in
FIG. 12. The custom codes for the VTR are determined so as not to cause
the malfunction in the case where the maker of the television is different
from that of the VTR. As shown in FIG. 15, the custom codes corresponding
to the maker codes are assigned to the different makers. FIG. 15 shows an
example in which the maker codes in the case where the VTR contains the BS
tuner are different from those in the case where the VTR does not contain
the BS tuner. Therefore, if those custom codes of the makers are, together
with the remocon codes shown in FIG. 12, previously, inclusively stored in
the memory in the picture recording control signal generating circuit 14
so that those can be selected on the basis of the maker codes, even when
the maker of the television 1 is different from that of the VTR 18, the
code corresponding to the maker of the VTR 18 used can be output from the
television 1, and thus the picture recording reserve can be performed.
Confirming whether or not the picture recording channel is proper can be
performed in such a way that when the items of CH is selected on the
displayed screen of FIG. 9 by operating the cursor key 25m of the remocon
transmitter 25 of FIG. 7 and then the test key 25b is pressed down, the
same command as the CH command in the timer picture recording is
transmitted to the VTR 18. In this case, to the remocon light receiving
portion 19 of the VTR 18, both the infrared ray signal which is
transmitted when pressing down the test key 25b of the remocon transmitter
25 and the infrared ray signal which is output from the remocon infrared
ray emitting portion 22 are input at the same time. Therefore, the
procedure may be available such that after a certain lapse of time after
pressing down the test key 25b in order to prevent the malfunction due to
both the signals, the infrared ray signal which has been obtained by the
modulation on the basis of the remocon code is output from the remocon
infrared ray emitting portion 22.
In the preferred embodiment of the present invention, both the main
microcontroller 8 and the submicrocontroller 14b are individually provided
as the controller. However, alternatively, one microcontroller may also be
constituted by uniting both the main microcontroller and the
submicrocontroller. In addition, the description has been given with
respect to the method in which the remocon codes of the main other makers
are previously stored in the submicrocontroller 14a. However, that method
may also be constituted by the so-called "learning function" in which the
procedure is displayed by the picture display circuit 7, the remocon code
of the VTR 18 to be used is read by the infrared ray receiving portion 12
of the television 1, and the above-mentioned commands corresponding to the
power source, the channels, the picture recording, and the stop are
stored. In addition, in the present embodiment, as for the reserve method,
the method based on the numeral input has been described. However,
alternatively, the method may also be available such that by pressing down
