Establishing a datapipe in a video stream |
摘要 |
A method and apparatus for establishing a "datapipe" in a digital transport stream. Specifically, opportunistic data are packetized into packets that are compliant with a particular transport protocol, e.g., as part of an MPEG transport stream. The opportunistic data are inserted into a multiple program per channel digital television transport stream. The opportunistic data are uniquely identified using at least one unique packet identification (PID) label that will allow a receiver to quickly determine whether a packet is carrying opportunistic data or television data. <IMAGE> |
