The TW2866 is Techwell's second-generation 4-in-1 video decoder and audio codec plus video encoder for security surveillance applications. The device includes four high quality NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data. Each channel contains a 10-bit ADC and proprietary clamp/gain controller and utilizes 4H comb filter for separating luminance & chrominance to reduce cross noise artifacts. The TW2866 adopts image enhancement techniques such as IF compensation filter, CTI and programmable peaking. In addition, TW2866 includes one NTSC/PAL video encoder with two 10-bit DACs to support CVBS and YC output. The TW2866 also includes an audio codec which has five audio ADCs and one DAC. A built-in audio controller can generate digital outputs for recording/mixing and accepts digital input for playback.
