System for forming and processing program specific information containing text data for terrestrial, cable or satellite broadcast

摘要

Packetized program information used in video processing and storage medium formats includes multiple text strings. A decoder decodes packetized program information containing multiple text strings associated with a program. The decoder determines from a first indicator in the packetized program information a type of coding and compression employed in encoding a first text string. The decoder decodes the first text string with a decoding function selected in accordance with the determined type of coding and assembles decoded text string elements to form an output text string.
