ABSTRACT:
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 information of a program of a program group, the program information including the attribute designating a recording method of a program belonging to the same program group, and a broadcast receiving apparatus for receiving the program information produced by the program information producing apparatus and performing the recording of the program in accordance with the designated recording method.
