SETUP / ROUTING :

Setup of the module and the Bus routing

The Dolby OEM module CAT561 has 8 physical PCM audio inputs and may be configured
for 4 different operating modes :

A) Two independent encoders

stream 1 – 5.1 (D-D, D-D plus, AAC, HE-AAC)

(independent audio inputs

stream 2 – 2.0 (D-D, D-D plus, AAC, HE-AAC)

Independent metadata)


B) Two 5.1 encoders

stream 1 – D-D, D-D plus, AAC, HE-AAC

with different data rates

stream 2 – D-D, D-D plus, AAC, HE-AAC

(but same audio inputs)


C) Two encoders used for

one stream for the main audio, one stream for an associated

associated services

audio. The streams may be output in parallel from both encoders
(AKA dual PID – DVB packet identifier) :
