BACKGROUND OF THE INVENTION
The present invention relates to a broadcast system for broadcasting
additional or supplemental program information multiplexed with main
program information including video and audio data, and also related to
apparatuses used in a broadcast station or a receiver apparatus using the
program information. More specifically, the present invention utilizes the
additional or supplemental program information to realize various types of
program recording or reservation services and program table displays.
Starting a prototype digital satellite broadcast service from the year
2,000 is a goal to be attained for the broadcast industries or
enterprisers in Japan. To this end, digitized broadcasting and related
techniques have been steadily developed. The European standardizing
organization has already decided to adopt a digital broadcast standard DVB
(digital video broadcasting) that uses the MPEG2 technique for coding
and/or multiplexing video and audio data. And, the digital satellite
broadcast service conforming to this standard actually started from the
year 1,995.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a broadcast system which
transmits improved program information data and provides an improved
display of the program table so as to allow users to make a reservation
for a target program in various ways. Furthermore, the present invention
has an object to provide improved arrangement for the apparatuses
constituting this broadcast system.
In order to accomplish the above-described and other related objects, in a
broadcast system of the present invention, a broadcast station produces
program information including information of a next program in a series of
programs, or program information of a main program and its spare program
scheduled in a same time slot, or program information linking two
programs, or program information designating a preferable display format
of a program table, or program information including regional information.
A receiving apparatus allows a sequential reservation for series programs
or a reservation for a spare program, and automatically switches a program
to a linked program when the view requirements are not fulfilled, and
displays a characteristic program table or a local program table, and
performs a bandwidth adjustment in accordance with a priority order when
the broadcast station puts the priority order to each program information.
One aspect of the present invention provides a broadcast system for
broadcasting a program and related program information, comprising a
program information producing apparatus for broadcasting program
information of a subjective program of a program group, the program
information of the subjective program including program information of
other program belonging to the same program group, and a broadcast
receiving apparatus for receiving the program information of the
subjective program and displaying the subjective program together with the
program information of other program belonging to the same program group.
This arrangement allows the users to confirm the content of a program to
be broadcasted next time in a series of programs.
Another aspect of the present invention provides a program information
producing and transmitting method for a program information producing
apparatus. This method comprises a step of producing program information
of a subjective program of a program group, the program information of the
subjective program including program information of other program
belonging to the same program group, and a step of transmitting the
subjective program and the produced program information of the subjective
program. This method allows the users to confirm the content of a program
to be broadcasted next time in a series of programs.
Another aspect of the present invention provides a broadcast system for
broadcasting a program and related program information, comprising a
program information producing apparatus for broadcasting program
information of a subjective program of a program group, the program
information of the subjective program including program information of a
next program to be broadcasted next time and belonging to the same program
group, and a broadcast receiving apparatus for receiving the program
information of the subjective program sent from the program information
producing apparatus and displaying the subjective program together with
the program information of the next program based on the received program
information of the subjective program, thereby allowing a viewer to make a
reservation of the next program. This arrangement allows the users to
confirm the content of the next program to be broadcasted next time in a
series of programs and also allows the users to make a reservation of the
next program.
Another aspect of the present invention provides a program information
producing apparatus for a broadcast system broadcasting a program and
related program information. This apparatus comprises a program group
information producing means for producing program information of a
subjective program of a program group, the program information of the
subjective program including program information of a next program to be
broadcasted next time and belonging to the same program group, and a
transmitting means for transmitting the subjective program and the program
information produced by the program group information producing means.
Another aspect of the present invention provides a program information
producing and transmitting method for a program information producing
apparatus. This method comprises a step of producing program information
of a subjective program of a program group, the program information of the
subjective program including program information of a next program to be
broadcasted next time and belonging to the same program group, and a step
of transmitting the subjective program and the produced program
information of the subjective program.
Another aspect of the present invention provides a receiving apparatus for
a broadcast system, wherein the receiving apparatus receives program
information multiplexed with video and audio data, and the receiving
apparatus updates the tuning processing in accordance with the received
program information. With this arrangement, the tuning processing of the
receiving apparatus can be updated in accordance with the received program
information.
Another aspect of the present invention provides a receiving apparatus for
a broadcast system, wherein the receiving apparatus receives program
information multiplexed with video and audio data, and the receiving
apparatus updates recording processing in accordance with the received
program information. With this arrangement, the recording processing of
the receiving apparatus can be updated in accordance with the received
program information.
Another aspect of the present invention provides a receiving apparatus for
receiving program information, comprising a program group information
managing means for reading program information of a next program to be
broadcasted next time from program information of a subjective program of
a program group, and displaying the read program information of the next
program together with the subjective program, and a reserving means for
performing reservation processing in response to a user's operation for
making a reservation for the next program.
Another aspect of the present invention provides a broadcast system for
broadcasting a program and related program information, comprising a
program information producing apparatus for broadcasting program
