SSM Video Switching
Figure 10
IC 7017 located on the SSM performs the Video and Audio switching for the Composite inputs to the
SSM. Selected Y or Composite video is output on Pin 1 before being fed to the SSB. Selected C is
output on Pin 3 and is fed to the SSB. Selected Composite Video for the PIP window is output on Pin
39 and fed to the PIP panel. If an SVHS source is selected for the PIP window, the YC is combined in
7017 and output on Pin 39. IC 7017 is controlled by the Microprocessor via the I2C SDA and SCL
lines on Pins 33 and 32.
