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 Basic Engine (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 Basic Engine for recording.
9.5.3
Playback Mode
During playback, the serial data from the Basic Engine is going
directly to the PNX7100 via the serial front-end I2S interface.
The PNX7100 is an MPEG CoDec and has the following
outputs:
•
To the analogue board: analogue video RGB, YC, CVBS
on connector 1904.
•
I2S audio (PCM format) on connector 1900.
•
SPDIF audio (digital audio output) on connector 1904.
•
Progressive video on connector 1704.
•
Communication gateway (RS232) on connector 1104.

Basic Engine Interfaces
AV2 Basic Engine (VAE8015 and VAE8020)
The UART interface (for the S2B commands) between the
Chrysalis and the servo processor (MACE3 on the BE module),
controls the AV2 Basic Engine during record and playback
mode. For data transport, an I2S bus is used.
For detailed information on the AV2 BE module, see Service
Manual 3122 785 12470.
