Integrated Video, Audio and Data (cont.)
Interactive internet type data - can be inserted in MPEG-2 transport stream without affecting any other data, you will still be MPEG-2 system compliant, it is upto the decoders to figure out if they can handle the data or not (TV v/s PC- we can use the same broadcast)
Interactive internet type data - must be a “program” and not part of another program - therefore decoder must be capable of tuning to two programs
