This article describes a high-performance video capture circuit. The video decoder used in this system is Philip's high-performance video A/D converter SAA7111. This device is a high-performance video input processing device widely used in desktop video, multimedia, digital TV, image processing, video telephony. The device uses a 3.3 V CMOS circuit, highly integrated analog front end and digital video encoder; includes 2 analog video processing channels, 1 clock generation circuit, 1 auto-clamp and automatic gain control circuit, 1 multi-format digital decoding , 1 brightness/contrast/saturation control circuit, and color space matrix. The SAA7111 output is a 16-bit VPO bus that supports data output formats of different bit widths. The output formats supported by the SAA7111 include: 12-bit YUV411, 16-bit YUV4:2:2, 8-bit CCIR-656, 16-bit 565RGB, and 24-bit 888RGB. See the figure below.
