Note: The only supported mode for CATV applications is: Audio Codec: AC3 Audio Bitrate: 192k Channel: Mono/Stereo TS Settings Transport stream (TS) is a format that allows multiplexing of digital video and audio and synchronizes the output. Radiant Communications Corporation 2016... - Page 29 Suppose each channel consists of one video stream, one or two audio streams, and any necessary metadata. A receiver wishing to tune to a particular "channel" merely has to decode the payload of the PIDs associated with its program. It can discard the contents of all other PIDs.
