AV Signal Flow
(TUMJ Assy)
The TUMJ assembly contains a TV tuner, separate Audio and Video
selector IC's and an Output Video driver IC. All AV inputs and outputs to
the main assembly except the DV input/output are processed on the
assembly.
Video selector IC3301 can select Y/C or composite video from any of the 3
sources or the tuner as its output source for the main assembly. Input 1
can be setup as a Auto Record Input (starts and stops recording by
monitoring the Y/C or Video input).
Video Driver IC3501 receives Y/C, composite or component signals from
the main assembly and sends the signals to output jacks 1, 2 or component.
