Abstract
Abstract A plurality of classification items each including a plurality of detailed items for recognizing broadcasting programs per se and program elements included in each of the broadcasting programs are provided wherein the contents of each of the broadcasting programs are represented by the classification items and the detailed items that are respectively represented by the identification data are used to form scheduled program information. The scheduled program information is broadcast together with the corresponding table data for the identification data and the data for character display of the classification items and the detailed items corresponding to the identification data. Program schedules for various kinds of broadcasting programs can be broadcast with a reduced amount of data.

Claim 1
Independent Claim
111 words
A program information broadcasting system comprising: a step of providing a plurality of classification items each comprising a plurality of detailed items for identifying broadcasting programs per se or program elements included in each of the broadcasting programs; a step of forming scheduled program information by representing the contents of each of the broadcasting programs with said classification items and detailed items, and representing said classification items and detailed items with identification data, respectively; and a step of broadcasting said scheduled program information and corresponding table data for the data for the character display of said classification items and said detailed items corresponding to said identification data and said identification data.
Claim 2
Dependent Claim
32 words
A program information broadcasting system as defined in claim 1, wherein the scheduled program information contains information for recognizing broadcasting start time and broadcasting end time on every program to be broadcast.
Claim 3
Dependent Claim
40 words
A program information broadcasting system as defined in claim 1, wherein the scheduled program information contains information for recognizing broadcasting start time and broadcasting end time on every program element unit included in each of the programs to be broadcast.
Claim 4
Dependent Claim
144 words
A program information display method comprising: a step of extracting, from received broadcasting wave signals, scheduled program information in which the contents of programs to be broadcast are represented by a plurality of classification items and detailed items for each of said classification items, and said classification items and said detailed items are represented, respectively, by identification data, and corresponding table data for data for character display of said classification items and said detailed items corresponding to said identification data and said identification data, a step of replacing said extracted identification data of said scheduled program information with data for corresponding character display by using said extracted corresponding table data, thereby generating program schedule data; and a step of displaying the program schedule for the contents of the program to be broadcast by character display on a display based on the program schedule data.
Claim 5
Dependent Claim
56 words
A program information display system as defined in claim 4, wherein the method comprises extracting, from the scheduled program information, a program having identical classification items or detailed items with those designated by a user as program information and displaying said extracted program on a display in a state that can be recognised by the user.
Claim 6
Dependent Claim
60 words
A program information display system as defined in claim 4, wherein the method comprises extracting, from the scheduled program information, program element comprising identical classification items or detailed items with those designated by a user, generating program schedule data consisting of only the extracted program element and displaying the program schedule on the display based on the program schedule data.
