7.6.1.3.2 Enabling
The video pipeline #n is enabled/disabled by setting/resetting the
DSS.
[0].VIDENABLE bit. While the video pipeline is enabled/disabled, the
video layer is visible/not visible on the screen (LCD panel or TV set).
The video up/downsampling block for the video pipeline #n is programmed by setting the
DSS.
