Audio Decoding and Output Stage

B.2.1

General

 

The RX83xx Receiver is capable of simultaneously decoding two PES streams of

audio from the transport stream or the RX8200 is capable of decoding four PES streams. Each of the decoders is identical in operation, but act independently of the other.

Each channel supports extraction of the following types of coded audio from the Transport Stream as follows:

•MPEG-1, Layer 2 Audio (Musicam): ISO/IEC 13818-3

•Dolby Digital AC-3 Audio: ATSC document A/52

Audio component selection is automatic or may be specified from the User Interface or remote interfaces. The RX8000 Receiver automatically detects the audio type of the selected audio component and applies the appropriate algorithm. Audio component selection is based on the position of the component descriptor in the PMT. Audio 1 takes the first component and Audio 2 the second. These may be overridden by selecting User-specified component PIDs.
