In all HD modes, the video encoder will be switched off. Either a separate sync signal
or the embedded syncs of the D1 input can be used to generate the sync raster
driving the display device.
The PNX8510/11 has two independent stereo channels, each connected to a
separate audio interface. The primary audio channel is usually associated with the
primary video channel and carries the accompanying sound information. The
