The video input can be selected among YPbPr (component) input with interlaced video, S-Video and
Composite video, or set to Automatic.
When set to Automatic the Tx unit will perform automatic detection of a video signal in the following order
of precedence:
- YPbPr-interlaced video
- S-Video
- Composite Video.
Writing to register 0x03 commands the system to a desired video input port.
Reading from register 0x04 presents the video input port that is currently active.
Note: Register 0x03 and 0x04 are applicable only to WVM1103 model.
