This register should be written to all four video decoder cores.
Blue screen output [1:0] (internal use only)
Fully programmable color of "blue screen" to support clean input/channel switching. When enabled, in case of lost lock, or when
forced, the TVP5158 waits until the end of the current frame, then switches the output data to a programmable color. Once
displaying the "blue screen", the inputs can be switched without causing snow or noise to be displayed on the digital output data.
Once the inputs have settled the "blue screen" can be disabled, where the TVP5158 then waits until the end of the current video
frame before re-enabling the video stream data to the output ports.
