Video Part
The analogue video input signals CVBS, YC, and YUV/
RGB (RGB for EURO and YUV for USA), are routed via
the analogue board to connector 1904 and sent to IC7004
(SAA7118, Video Input Processor).
The digital video input signals are routed from the DV-In
connector (item 1200) via ICs 7200 (1394 PHY) and 7201
(1394 LINK) to IC7400 (PNX7100, Chrysalis).
The multistandard Video Input Processor (VIP, IC7400)
encodes the analogue video to digital video stream
(CCIR656 format). It provides filtering of the analogue
signals and separation of luminance and chrominance by
a comb filter. The output stream, named ITU_IN(7:0), is
then routed to the Chrysalis IC (PNX7100). This IC
encodes and decodes the digital video stream into/from
MPEG2 format.

Audio Part
I2S audio is sent from the analog board to the Chrysalis IC
via connector 1900. The Chrysalis compresses the I2S
audio data into an MPEG1-L2/AC3 audio stream.
Front-end I2S
IC7400 (Chrysalis) interfaces directly to the DVDR
mechanism (BE) via connectors 1100 (clock and data) and
1105 (control). For future use (with AV3 BE module, HDD,
or card reader) it also interfaces to an IDE bus via
connector 1102 .
It buffers the data streams that are coming from (or going
to) these hardware modules.
In the Chrysalis, the video MPEG2 stream and the audio
AC3 stream are multiplexed into an I2S stream. The serial
data are sent to the DVDR mechanism for recording.
