A SYSTEM FOR ACQUIRING AND PROCESSING BROADCAST PROGRAMS AND PROGRAM GUIDE DATA. |
摘要 |
<p>Decoder system initialization involves scanning to associate a particular program guide with individual channels. A similar procedure is also performed upon introduction of a new channel. A system for acquiring program guide information conveyed on one of a plurality of broadcast channels involves scanning through received broadcast channels to identify program guides available on individual channels. A program guide of a selected program guide type (e.g. analog-VBI type, MPEG PSI type or ATSC PSIP type) is associated with a broadcast channel by updating a video decoder database. The program guide of the selected program guide type is acquired and used in capturing packetized program information comprising a program conveyed on an individual broadcast channel. In another feature, data received on an individual broadcast channel is examined to identify program guides of particular type in a predetermined order.</p> |
