8.4.1. Record
Mode
The switching of the various video input signals is done
by the Video Input Processor on the Digital Board. These
signals are directly routed to the digital board through
connector 1205 on the Analog Board
8.4. Digital
Board
The Digital Board is based on the highly integrated LSI
‘Domino’ BGA chip (Ball Grid Array), DMN-8652. This IC
has 2 on-chip ATAPI controller and integrates an analog
video encorder, and provides build-in support for non-
simultaneous progressive and interlaced video output. A
1394 link layer function is also integrated, requiring only
a simple external physical layer device. The DMN-8652
has a set of integrated USB Physical Layer Interface.
The board encodes and multiplexes analogue video and
digital uncompressed audio (I2S) into an MPEG2 stream.
This MPEG2 stream is formatted for recording by the
DVD+RW engine. In the playback, the board will decode
the MPEG2 video into analogue video. In addition, a
DV stream can be received via IEEE 1394 (i-Link), and
transformed to MPEG2 format.
