description

The TW2866 includes four high-quality NTSC/PAL/SECAM video decoders that convert analog composite video signals into digital composition YCbCr data security applications. Each channel contains a 10-bit ADC and patented clamping circuitry as well as a gain controller, and a 4H comb filter separates luminance and chrominance to reduce crossover noise unnatural. The TW2866 uses image enhancement techniques such as IF compensation filters, CTI and programmable peaks. The TW2866 also includes two 10-bit DACs supporting NTSC/PAL video encoders with CVBS and YC outputs. The TW2866 also contains an audio codec with five audio analog-to-digital converters and one digital-to-analog converter. A built-in audio controller generates recordings/mixes for playback and accepts digital inputs and digital outputs.
