Bt254 Overview
The Bt254 Image Digitizer is designed to digitize three channels of video signals, such as RGB, YIQ, YUV, etc., generating up to 24 bits of color pixel information. The architecture also supports single-channel digitization of NTSC and CCIR video signals, generating 8 bits of gray-scale pixel information. The Bt254 supports 24-bit true-color, 15-bit true-color, 8-bit true-color, and 8-bit pseudo-color modes.
