B.1.2 Audio Decoding and Output Stage
B.1.2.1 General
The RX8000 Integrated Receiver/Decoder is capable of simultaneously decoding at
least two PES streams of audio from the Transport Stream. Each of the decoders
are 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
• AAC Audio
• HE-AAC Audio
• Linear Audio
• Dolby E pass-thru
• Enhanced Dolby Digital pass-thru
Audio component selection is automatic or may be specified from the User Interface
or remote interfaces. The RX8000 Integrated Receiver/Decoder 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.
