ASI main input is active
and is provided to the
encoders as
internal signal source.
The H.264/ AVC HD
service (SID 45) is
passed in the mode
decoder through the
internal output to the
MPEG-2 encoder.
The signal from internal
input is encoded to a
MPEG-2 service.
Input signal of the
encoder A is set to
“Intern TS“.
