13-3 H/W Function Specifications
13-3-1 Main PCB H/W Function Specifications
The main PCB records and plays back the electronically transformed video signal which comes through the
CCD of the Camera Lens Ass’y, with the audio signal in DV format on a 6.35 mm tape.
13-3-2 Camera Circuit Block H/W Function Specifications
DSP6 receives the digitized CCD signal or ITU-R656 data and outputs the video signal after going through
the color and brightness signal process. Finally, it performs encoding/decoding JPEGs at the SVGA rate and
MPEG4s at 30 FPS by using this video signal.
Using a USB 2.0 device, this compressed JPEG/MPEG data can be transferred to a PC and saved on
Flash memory cards, such as Memory Stick (Pro) and SD/MMC card.
DSP6 supplies a 54 MHz, 27MHz clock to the DV1 chip in all modes, and it processes the ITU-R656 data
as IN/OUT mode synchronized to 27MHz clock. MICOM controls the mode selection between the Memory
card mode and Camera mode.
