The TSB15LV01 is a video signal processor integrated with a 1394 link layer controller. It is designed to be the

center of a host-controlled, full-motion color camera when coupled with a 1394 PHY, CCD sensor and driver,

analog front end, and an external EEPROM device. A camera based on the TSB15LV01 is compliant with the

IEEE 1394a standard and the 1394 Trade Association’s Digital Camera specification, Draft 1.04.

The TSB15LV01 offers the advantage of 24-bit true-color digital video processing. This gives superior video

quality at higher sustained data rates. Isochronous transfer of the video data and asynchronous control of the

camera are accomplished via the 1394 high-speed serial bus, operating at data rates of up to 400 Mbits/s. This

bus allows noncompressed full-motion digital video at rates of 30 frames/sec. Use of this serial connection

eliminates the need for expensive video capture cards. The chipset supports the YUV 4:1:1, YUV 4:2:2, YUV

4:4:4, and RGB 24-bit formats.

The video signal processor (VSP) portion of the device incorporates proprietary digital image processing

techniques, implemented with an advanced digital signal processing (DSP) ASIC. These techniques enable a

camera to achieve excellent color accuracy and resolution. The use of a custom advanced CMOS ASIC process

allows for both the advanced digital image processing techniques and for advanced color space conversion. This

allows the multiple output formats required for a multipurpose video conferencing camera. Use of this advanced,

low-power CMOS process also enables the camera to be powered by a notebook computer operating on battery

power. The device is designed to work with CCDs that have a pixel resolution of 640(H) y 480(V). This

resolution meets the VGA square pixel standards.
