2.7.4 1394 interface control
The DECK CPU has the function of the host microcomputer of the 1394 interface. It mainly controls the
LINK IC, PHY IC and 1394 bus besides AV/C command processing. The AV/C command is classified into
the VCR control commands such as for PLAY, STOP, FF, REW, REC operations and for status information
such as time code, mode status, etc.
For details of the 1394 interface (i.LINK), refer to the Technical Guide to the i.LINK.

2.7.5 JLIP Video Capture
The DECK CPU incorporates the asynchronous serial communication (UART) port for communication with
external equipment (personal computer, etc.). The UART port is used for image data transmission for
inputting DVC playback picture that is captured by use of the JLIP Video Capture into a personal computer.
When a DVC playback picture is captured, playback data for 1 frame is once held by the DRAM and then
transmitted to the DECK CPU through the 16-bit bus and it is finally output from the UART port to a
personal computer. The image data transmitted to a personal computer is formatted in the DV stream, and
the personal computer encodes the DV data with the software.
