Dolby E, Dolby D, LPCM, and Mpeg1Layer2
As of 1.07.01 firmware, the RD-60 supports 16 channels of SDI embedded audio output
with support of up to two audio pass-throughs, up to 8 pairs (sixteen channels) of Mpeg 1
Layer 2 audio, and up to 8 pairs of Dolby Digital decoding. An audio pass-through consists
of a Dolby E 20 Bit, Dolby E 16 Bit, Dolby Digital, or a Linear PCM stream that is preserved
(not decoded) from the transport stream and embedded on the SDI output.
Mpeg 1 Layer 2 decode support includes 48kHz 32 - 384kbps. Interoperability support
includes stream type 0x03 and stream type 0x04, PES aligned and unaligned audio, and
also includes Mono ( with audio duplication feature ), Dual Mono, and Stereo decoding.
Dolby Digital decode support includes a stereo output pair for each Dolby Digital Audio PID
assignment ( multi-channel Dolby Digital 5.1 for example is down-mixed to 2/0 ).
The RD-60 automatically configures the audio engines upon acquisition of a program when
engines and sdi matrix are configured to ‘AUTO’. The audio is automatically output based
on ascending audio PID order from the selected program. The left hand status panel of the
Web UI shows current active SDI audio output. The current left hand status panel audio
type codes are as follows:
MU - Configured for Mpeg1Layer2 decoding ( stream type 0x03 / 0x04 )
DD - Configured for Dolby Digital decoding ( stream type 0x81 / 0x06 )
DP - Configured for Dolby Digital pass-through ( stream type 0x81 / 0x06 )
LP - Configured for LPCM pass-through
DE - Configured for Dolby E pass-through ( 16 / 20 Bit support )
AA - Configured for AAC decoding (AAC-LC, AAC-HEv1, AAC-HEv2)
