System for forming and processing text data for use in program specific information for broadcast

摘要

Packetized video program information used in video processing and storage medium formats includes program related text messages. A decoder decodes packetized video program information including program related text messages. The decoder determines a broadcast programming time segment associated with a desired program related text message and identifies program related text message data occurring in the determined broadcast programming time segment. The decoder acquires the identified program related text message data and formats the text message data for display.
