Features
The TW2864 is Techwell’s 4th generation 4-in-1 video decoder and audio
codec for security surveillance applications. The device includes four high
quality NTSC/PAL video decoders that convert analog composite video
signal to digital component YCbCr data. The TW2864 contains four 10-bit
ADCs and proprietary clamp and gain controllers and utilizes adaptive 4H
comb filter for separating luminance & chrominance to reduce cross noise
artifacts. The TW2864 adopts the image enhancement techniques such as
IF compensation filter, CTI and programmable peaking. The TW2864 also
includes audio codec which has four audio ADCs and one audio DAC. A
built-in audio controller can generate digital outputs for recording/mixing
and accepts digital input for playback.
