CODES
The decoded and/or scaled video stream can be captured
via PCI-DMA to the system memory, and/or can be made
available locally through the video side port (VP), using
some of the GPIO pins. Two types of applications are
intended:
Streaming real-time video to a video side port at the
VGA card, e.g. via ribbon cable over the top
Feeding video stream to a local MPEG compression
device on the same PCI board, e.g. for time shift viewing
applications.
The video port of the SAA7130HL supports the following
8 and 16-bit wide YUV video signalling standards
(see Table 7):
VMI: 8-bit wide data stream, clocked by LLC = 27 MHz,
with discrete sync signals HSYNC, VSYNC and
VACTIVE
ITU-R BT.656, parallel: 8-bit wide data stream, clocked
by LLC = 27 MHz, synchronization coded in SAV and
EAV codes
VIP 1.1 and 2.0: 8-bit or 16-bit wide data stream,
clocked by LLC = 27 MHz, synchronization coded in
SAV and EAV codes (with VIP extensions)
Zoom Video (ZV): 16-bit wide pixel stream, clocked by
LLC/2 = 13.5 MHz, with discrete sync signals HSYNC
and VSYNC
ITU-R BT.601 direct (DMSD): 16-bit wide pixel stream,
clocked by LLC = 27 MHz, with discrete sync signals
HSYNC, VSYNC/FID and CREF
Raw DTV/DVB sample stream: 9-bit wide data, clocked
with a copy of signal X_CLK_IN.
The VIP standard can transport scaled video and
discontinuous data stream by allowing the insertion of ‘00’
as marker for empty clock cycles. For the other video port
standards, a data valid flag or gated clock can be applied.

Analog audio pass-through and loop back
cable
Most operating systems are prepared to deal with audio
input at only one single entry point, namely at the sound
card function. Therefore the sound associated with video
has to get routed through the sound card.
The SAA7130HL supports analog audio pass-through and
the loop back cable on-chip. No external components are
required. The audio signal, that was otherwise connected
to the sound card line-in, e.g. analog sound from a
CD-ROM drive, has to be connected to one of the inputs of
the SAA7130HL. By default, after a system reset and
without involvement of any driver, this audio signal is
passed through to the analog audio output pins, that will
feed the loop back cable to the sound card line-in
connector. The AV capture driver has to open the default
pass-through and switch in the TV sound signal by will.
