Functional description
7.1
Video pipeline
The video pipeline contains two independent video channels. The primary channel is
used to display graphic or video content on a standard television, CRT monitor or an
HDTV system. The secondary video channel may connect to a VCR or a second
standard TV for recording or secondary display purposes. No high definition or RGB
output is available through the second video channel.
The two video pipelines are driven by two standard D1 interfaces, which can operate
in various modes in 8 or 10-bit precision. The video modes are described below
.
7.1.1
Video modes
The video interfaces and sync raster engines are designed in a generic way. The only
limiting factor is the data rate of the received video streams. All formats with a total
interface speed requirement below 81 MHz can be displayed by the
PNX8510/11
