Dolby E, Dolby D, LPCM, and Mpeg 1 Layer 2
As of 0.01.00 firmware, the RD-70 supports 16 channels of SDI embedded audio output
with support of up to four audio pass-throughs, up to 8 pairs (sixteen channels) of aligned
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 (sometimes called Mpeg 1 Layer 2), stream type 0x04
(sometimes called Mpeg 2 Layer 2), PES aligned/unaligned audio, 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 ).
