Both MPEG1 and MPEG2 allow for lots of out-of-band data (in fact, entire video or audio streams can be sent as out-of-band data). However, I don't know whether closed-captioning has specifically been addressed or standardized. I suspect it has been for MPEG2, since that is being touted as a broadcast standard. One possibility for the multiple simultaneous audio streams is simultaneous broadcast in multiple languages, btw. Just pick the correct audio channel(s) and listen in English, French, German, Spanish, whatever. -- ***** / walker@unx.sas.com *|_o_o|\\ Doug Walker< BIX, Portal: djwalker *|. o.| || \ CompuServe: 71165,2274 | o |// ====== Any opinions expressed are mine, not those of SAS Institute, Inc.
