These three bits define the format of digital video output port.
000: Single channel 10-bit CCIR656 video stream for SD outputs.
The clock rate of the strem is 2X pixel rate.
For 480i format, clk2x = 27 MHz.
For 480p format, clk2x = 54 MHz.
001: Two channel 10-bit CCIR656 video streams. The video data is
in YCbCr 422 format. The data rate equals to the pixel rate.
010: Three channel 10-bit video streams with embedded sync
SAV/EAV. The video format can by YCbCr 444 or RGB. And the
data rate equals to the pixel rate.
011: Three channel 10-bit video streams with dedicated
HS/VS/FID/ACTVID sync signals. The three channel component
digital video can be RGB or YCbCr444 format. It can be used for all
display formats. And the data rate equals to the pixel rate.
100: Two channel 10-bit video streams with dedicated
HS/VS/FID/ACTVID sync signals. The video data format is
YCbCr422. The first channel is Y. and CbCr are multiplexed on the
second channel. It can be used for all display formats. And the data
rate equals to the pixel rate.

Self test mode:
0: The HD encoder will be in normal operation mode
1: The HD encoder will enter self-test mode. The encoder will
generate a 100% color bar internally. The video data from OSD will
be ignored.

Bypass color space converter. This means that no color space
conversion is needed. If it is not bypassed, the proper coefficient
should be set in the corresponding registers.
