BACKGROUND OF THE INVENTION
This invention relates to telephone answering machines and, more
particularly, to an answering machine for a video telephone. In a
preferred embodiment, the video answering machine is built into a
dual-deck video cassette recorder to share the components thereof and
provide additional capability thereto. More specifically, it relates to a
dual-deck VCR including answering machine logic whereby the VCR can also
be used to answer a video telephone system. The video cassette decks of
the VCR are switched between and are shared by the VCR and telephone
answering functions. The VCR can be switched between its answering mode of
operation and its VCR mode of operation by a remote controller.
Telephone answering systems for answering the telephone and recording a
message when the telephone is unattended are well known in the art and
used extensively in home and business. As shown in FIG. 1, the typical
telephone answering machine 10 is connected to a telephone 12 with a cable
14 containing the "tip" and "ring" pair of a telephone line on one side
and is connected to an incoming telephone line 16 (i.e. a tip and ring
pair) on the other side. The answering machine 10 typically contains two
audio tape drives 18, 20 containing audio tapes 22, 24, respectively.
Sometimes a single tape and drive is employed using a front portion of the
tape for the pre-recorded outgoing message and a back portion to record
incoming messages. Functionally, the two approaches are the same with the
use of two tapes being easier to implement. To use the machine 10, the
user records an outgoing message on one tape 22. When the machine 10 is
subsequently turned on and an incoming call rings in on the telephone line
16, the machine "answers" the call and plays the message on the tape 22
which advises the caller that the machine 10 is answering and will record
a message for the caller. If the caller remains on the line and does not
hang up, any message spoken will be recorded on tape 24 for later playing
by the user to retrieve the message recorded thereon.
The video telephone system 26 of FIG. 2 is just becoming available on a
limited commercial basis and will gain popularity in the coming years as
the systems become less costly through mass production and general
availability. The system 26 comprises a telephone 12 having a video unit
28 connected between a cable 14' and an incoming telephone line 16 in a
manner similar to that of the answering machine 10 of FIG. 1. The video
unit 28 includes a video camera 30 for viewing a user thereof and a
monitor 32 for displaying what the video camera 30 of a calling system 26
is viewing. Thus, both parties to a conversation employing the system 26
can see each other. At present, however, there is no video answering
machine providing the benefits of the answering machine 10 of FIG. 1 with
full voice and video capability for use with the system 26 of FIG. 2. The
reason for employing a video phone is to be able to see the caller as well
as speak to him/her. Accordingly, it would be desirable to have a video
telephone answering machine which could be used by owners and users of
video telephone systems. A video telephone answering machine would,
because of the cost of the parts necessary to be incorporated therein, be
a high cost item. Therefore, it would be desirable to incorporate the
video telephone answering machine into another device providing additional
benefits so as to lower the apparent cost to the user for individual ones
of the benefits.
Wherefore, it is an object of the present invention to provide a video
telephone answering machine which could be used by owners and users of
video telephone systems to provide full video and audio outgoing and
incoming messages.
It is another object of the present invention to provide a video telephone
answering machine which is incorporated into another device providing
additional benefits so as to lower the apparent cost to the user for
individual ones of the benefits.
It is still another object of the present invention to incorporate a video
telephone answering machine into a dual-deck video cassette recorder to
share the major components thereof.
Other objects and benefits of the invention will become apparent from the
detailed description which follows hereinafter when taken in conjunction
with the drawing figures which accompany it.
SUMMARY
The foregoing objects have been achieved by the answering machine for
unattended answering of a video telephone system of the present invention
comprising, first video read/write deck means for containing a video
cassette and for writing video signals to the cassette and for reading
video signals therefrom; second video read/write deck means for containing
a video cassette and for writing video signals to the cassette and for
reading video signals therefrom; input means connected to a telephone line
for receiving incoming video telephone calls; output means connected to a
telephone line input of the video telephone system for bi-directionally
communicating with the video telephone system; and, answering logic means
connected to the first video read/write deck means, the second video
read/write deck means, the input means, and the output means for recording
outgoing video answering messages on the cassette of the first video
read/write deck means, for answering incoming calls on the telephone line,
for playing contents of the cassette of the first video read/write deck
means to incoming callers on the telephone line, for recording incoming
video messages on the cassette of the second video read/write deck means,
and for playing back recorded incoming video messages on the cassette of
the second video read/write deck means to a user.
In the preferred embodiment, the first video read/write deck means and the
second video read/write deck means comprise tape decks of a dual-deck
video cassette recorder (VCR). Also, the dual-deck VCR includes television
connection logic means for operably connecting the first video read/write
deck means and the second video read/write deck means to a television set
and a television signal input and switching means for selectively
switching connections from the first video read/write deck means and the
second video read/write deck means between the television connection logic
means and the answering logic means whereby the dual-deck VCR can be used
in conjunction with television viewing and recording and in conjunction
with video telephone answering. There is also control means for
selectively switching the switching means between an answering mode with
the answering logic means connected to the first video read/write deck
means and the second video read/write deck means and a VCR mode with the
television connection logic means connected to the first video read/write
deck means and the second video read/write deck means. The preferred
embodiment also includes remote control input means connected to the
control means for allowing a user to switch the switching means between
the answering mode and the VCR mode on demand.
According to one disclosed approach, the first video read/write deck means
and the second video read/write deck means are controlled by the
television connection logic means and the control means includes means for
receiving control requests for the first video read/write deck means and
the second video read/write deck means from the answering logic means and
for outputting them to the television connection logic means.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The assignee of this invention is also the owner of patents on a dual-deck
video cassette recorder (VCR) sold commercially under the tradename VCR-2.
While the present invention could be implemented employing two separate
VCRs with great additional cost and complexity, it is preferred that a
dual-deck VCR be employed to simplify the implementation of the present
invention. It is, however, the intent that the use of a preferred
embodiment for illustrative purpose not be limiting in any way as to the
breadth to be accorded the claims appended hereto and that they be given a
breadth in keeping with the scope and spirit of the invention described
hereinafter.
As shown in simplified form in FIG. 3, the video phone answering dual-deck
VCR 34 of the present invention is connected between the video unit 28 of
a video telephone system 26 and the incoming telephone line 16. A second
cable 36 connects the VCR 34 to the input of the video unit 28 normally
having the telephone line 16 input thereto so as to connect the VCR 34 in
series with the telephone line 16 and the video unit 28. As depicted in
FIG. 3, the VCR 34 has a pair of slots 38, 40 into which standard video
cassettes can be inserted. There is also an infrared (IR) signal receiving
window 42 into which IR control signals from a controller (not shown in
this figure) can be directed to control the operation of the VCR 34.
Turning now to FIG. 4, the construction of the VCR 34 which enables it to
perform its dual functions through the sharing of major components is
shown in functional block diagram form. Where components and their manner
of operation are well known to those skilled in the art and per se form
not part of the novelty of the present invention, there will be no attempt
to provide a detailed description thereof in the interest of simplicity
and the avoidance of redundancy herein. Since the novelty of the present
invention resides in the combination of functions and the sharing of
components to provide a synergistic effect to the combination, only those
aspects will be addressed in any detail.
The VCR 34 comprises a case 44 containing a pair of video tape decks 46 and
48, labelled "#1" and "#2", respectively. There is also VCR logic 50
connected to receive an incoming television signal on line 52 and to
transmit an outgoing television signal on line 54. All these components
are common and the same as contained in the commercially-available VCR-2
dual-deck VCR of the assignee hereof. Similarly, there is also answering
machine logic 56 contained within the case 44 and connected to a pair of
RJ-11 telephone jacks 58 on both sides for the convenient attachment of
the telephone line 16 and cable 36 thereto. The answering machine logic 56
is substantially similar to that contained within the answering machine 10
of FIG. 1 and many commercially available audio telephone answering
machines.
To perform the unique combinatorial functions of the present invention,
there is control logic 60 disposed between the VCR logic 50 and the
answering machine logic 56 and in communication with both logics 50, 56.
The control logic 60 is connected to the IR receiver 62 to receive IR
control signals 64 from a user using the hand-held controller 66. Manual
buttons and the like for controlling the VCR 34 could be mounted on the
case 44; but, use of a remote controller 66 is preferred. As those skilled
in the art will readily recognize and appreciate, the conventional control
functions associated with the VCR 34 operating in its VCR mode which are
normally included in the VCR logic 50 of the VCR-2 dual-deck VCR are moved
into the control logic 60 in the present invention. Upon receiving control
inputs from the control logic 60, the VCR logic 50 controls the movement
and operation of the two tape decks 46, 48 employing control lines 68, 70,
respectively.
Additionally, the outputs 72, 74 of the tape decks 46, 48 are connected to
the inputs 76, 78 of the VCR logic 50 and to the inputs 80, 82 of the
answering machine logic 56 through a pair of switches 84, 86,
respectively, which are controlled by the control logic 60. It will be
noted that there is no control connection from the answering machine logic
56 to the tape decks 46, 48 as would be present in the audio answering
machine 10 of FIG. 1. In the present invention, the VCR logic 50 has total
control of the tape decks 46, 48 through the control lines 68, 70 as
described above. Thus, when in the "answering" mode with the switches 84,
86 connecting the output lines 72, 74 from the decks 46, 48 to the inputs
80, 82 of the answering machine logic 56, the answering machine logic 56
requests movement of the tape decks 46, 48, for either reading or writing,
through the control logic 60 to the VCR logic 50. If desired, however,
separate control lines could be run from the answering machine logic 56 to
the two tape decks 46, 48.
As mentioned above, the functions performed by the answering machine logic
56 are substantially identical to those of the logic contained in the
audio-only answering machine 10 of FIG. 1. Thus, in addition to its normal
VCR operating functions, the controller 66 would have to have buttons 88
for switching the mode of the VCR 34 (including the switching of the
switches 84, 86) and performing the answering machine functions. Thus, for
example, an outgoing message video cassette (not shown) might be inserted
into tape deck #1, 46, and an incoming message video cassette (not shown)
might be inserted into tape deck #2, 48. A control function of RECORD
OUTGOING MESSAGE would then cause the video and audio input by a user
using the telephone 12 (or a separate microphone as is a common approach
for better fidelity) and the video unit 28 to be recorded on the cassette
in deck #1 in substantially the same manner as an audio outgoing message
tape is generated. For that matter, pre-recorded video cassette tapes with
messages by famous people (real or imaginary) might be sold for use in
deck #1 as a joke just as famous people audio tapes are now available
commercially. With the mode on "answer" and the VCR 34 turned on, an
incoming call would then be answered in the same manner as an audio-only
telephone answering machine; that is, the cassette in deck #1 would be
played by the answering machine logic 56 in the manner described above
using the VCR logic 50 to control the deck #1. The caller would then see
the called party and hear the pre-recorded message. If the caller decided
to leave a message, that message (both audio and video) would be recorded
on tape #2. A PLAY MESSAGES command input to the controller 66 would then
cause tape #2 to be rewound and played through the video unit 28.
When not in its "answer" mode and switched back to its "VCR" mode, the VCR
34 of the present invention would, of course, operate in its normal manner
as a VCR for both recording and play-back purposes.
Thus, it can be seen that the present invention has truly met its stated
objectives by incorporating a video answering machine into a dual-deck VCR
whereby the major components of the VCR are shared by the two functions
thereby providing diverse benefits at a greatly reduced cost per function.
