Figure 9-8 MPIF Video source selection
•
Audio source selectors. The MPIF contains two different
audio source selectors. The first selector selects which
audio signals are routed to the audio ADCs for further
processing in the digital domain. The selector has two
outputs, a primary channel and a secondary channel:
–
The primary audio channel is used for one stereo
signal. The secondary audio channel can carry a
second stereo signal or AM sound signal.
–
The second selector selects which audio signals are
fed to the analog audio outputs for SCART (EU only)
and line out. This selector has also two stereo inputs
for demodulated sound signals coming from the digital
video processor.
