Broadcast streaming formats


Notes:


MPEG Audio: As for the static format. MPEG Video: 25 Hz MPEG-2 video is specified. Subtitles: DVB Subtitles and Teletext formats are both provided for subtitles, with the DVB Subtitles taking precedence when both are provided. Java applications can detect and control subtitles, but programme access to Teletext data packets is not permitted. This is presumably to try to prevent unauthorized use of Teletext content. However, it may prevent useful services, such as searching and indexing multimedia content based on the text of subtitles. MHP supports Teletext for subtitles, not as an alternative to web-style content. Implementers are free to implement full Teletext outside MHP.
