TSB43DA42 in STB Application The set top box receives the MPEG2 transport stream from either satellite or cable sources. The MPEG2 demux device splits the audio and video portion of the MPEG2 transport stream. The video portion, including 2-channel audio, is input to the TSB43DA42 HSDI port. The TSB43DA42 performs any PID filtering or packet insertion, encrypts the stream using M6 cipher, and transmits the stream over 1394. The audio portion of the transport stream is packed into SPDIF format by the MPEG2 demux device using the IEC61937 standard. The audio stream is input to the TSB43DA42 audio port, encrypted using M6 cipher if necessary, and transmitted over 1394. The set top box also creates on screen display (OSD) graphics to transmit to the sink device. The system inputs the OSD data to the TSB43DA42 asynchronous transmit FIFO. The TSB43DA42 transmits the OSD using asynchronous packets to the sink device. 4 Submit Documentation Feedback |
