4 Channel Video Decoders and Audio Codecs For Security Applications
The TW2815 includes four high quality NTSC/PAL video decoders that convert analog composite video signal to digital component YCbCr data for security applications. The TW2815 contains four 10 bit ADC and proprietary clamp and gain controllers and utilizes a 4H comb filter for separating luminance & chrominance to reduce cross noise artifacts. The TW2815 adopts the image enhancement techniques such as IF compensation filter, CTI and programmable peaking. The TW2815 also includes an audio CODEC which has four audio Analog- to-Digital converters and one Digital-to-Analog converter. A built-in audio controller can generate digital outputs for recording/mixing and accepts digital input for playback.
