B.2 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.
