Abstract
Abstract A digital broadcasting system capable of causing any of physical channels selected by a broadcaster to be received as one of the channels available to users which is different from the physical channel selected by the broadcaster. For each of programs of each of the channels available to said users, a program information record comprising PSI (program specific information) is stored in a data base. The broadcaster is permitted to include, in the PSI, channel mapping information whose mapping destination is a channel (or a program) to be received instead of the channel for which said program information is intended. The program information records is inserted in broadcast transport streams on schedule and, if necessary, immediately after the broadcaster have included the channel mapping information in the PSI data.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
164 words
A digital broadcasting system capable of causing one of physical channels selected by a broadcaster to be received as one of the channels available to users; the system comprising: means for storing, for each of programs of each of said channels available to said users, a program information record comprising PSI (program specific information); means for permitting the broadcaster to include, in said PSI, channel mapping information whose mapping designation is a program to be received instead of a program for which said program information record is intended or a channel through which said program to be received is transmitted; means, responsive to a determination that PSI data for said program to be received includes channel mapping information indicative of a third program or channel to be received, for changing said channel mapping information such that the mapping destination of said channel mapping information is said third program or channel; and means for inserting said program information records in broadcast transport streams on schedule.
Claim 2
Dependent Claim
164 words
A digital broadcasting system capable of causing one of physical channels selected by a broadcaster to be received as one of the channels available to users; the system comprising: means for storing, for each of programs of each of said channels available to said users, a program information record comprising PSI (program specific information); means for permitting the broadcaster to include, in said PSI, channel mapping information whose mapping designation is a program to be received instead of a program for which said program information record is intended or a channel through which said program to be received is transmitted; means, responsive to a determination that PSI data for said program to be received includes channel mapping information indicative of a third program or channel to be received, for changing said channel mapping information such that the mapping destination of said channel mapping information is said third program or channel; and means for inserting said program information records in broadcast transport streams on schedule.
Claim 3
Dependent Claim
85 words
A system as defined in claim 1 , wherein: said program information record further comprises channel ID of said channel selected by said user and program guide data for either the program for which said program information record is intended for or the program identified by said mapping destination of said channel mapping information of said PSI data depending on whether said PSI includes said channel mapping information, and the system further comprises means for inserting said program information records in said broadcast transport streams.
Claim 4
Dependent Claim
33 words
A system as defined in claim 1 , wherein said channels, through which said programs including said program information record flow, consistently lead from a particular broadcast station to a particular receiving station.
Claim 5
Dependent Claim
182 words
In a digital broadcasting system in which a broadcasting center provides broadcast services through a plurality of physical channels which actually transmit service programs, a method for causing one of the physical channels selected by a broadcaster to be received as one of the channels available to users; the method comprising the steps of: storing, for each of programs of each of said channels available to said users, a program information record comprising PSI (program specific information); including, in said PSI for a program said broadcaster desires to be received, channel mapping information whose mapping destination is a program to be received instead of a program for which said program information record is intended or a channel through which said program to be received is transmitted; if PSI data for said program to be received includes channel mapping information indicative of a third program or channel to be received, changing said channel mapping information such that the mapping destination of said channel mapping information is said third program or channel; and inserting said program information records in broadcast transport streams on schedule.
Claim 6
Dependent Claim
182 words
In a digital broadcasting system in which a broadcasting center provides broadcast services through a plurality of physical channels which actually transmit service programs, a method for causing one of the physical channels selected by a broadcaster to be received as one of the channels available to users; the method comprising the steps of: storing, for each of programs of each of said channels available to said users, a program information record comprising PSI (program specific information); including, in said PSI for a program said broadcaster desires to be received, channel mapping information whose mapping destination is a program to be received instead of a program for which said program information record is intended or a channel through which said program to be received is transmitted; if PSI data for said program to be received includes channel mapping information indicative of a third program or channel to be received, changing said channel mapping information such that the mapping destination of said channel mapping information is said third program or channel; and inserting said program information records in broadcast transport streams on schedule.
