Abstract
In a video processing system and method, individual program channels are allocated first and second identification numbers. The first identification number is associated with an information provider. The second identification number is used in identifying a broadcast sub-channel from among a group of sub-channels associated with the first identification number. The first and second identification numbers in conjunction, are used in identifying data constituting a program transmitted on the broadcast sub-channel. The group of sub-channels are displayed along with the associated information provider in a hierarchical fashion for channel selection purposes.
