Mode 13 Configuration
Mode 13 is used to support OSD input from an OSD generator with an HDMI interface. Using this mode, the Serial Video Rx video is loaded
into memory before being called out by the OSD core. This video can then be scaled and blended with the video on the primary video channel.
It is possible to output the unblended video, the blended video or the raw OSD.
