Rev. 0.00
Feb 3, 2012 4-Channel Video Decoders and Audio Codecs and
Video Encoder for Security Application
The TW2866 includes four high quality
NTSC/PAL/SECAM video decoders that convert
analog composite video signal to digital
component YCbCr data for security applications.
Each channel contains 10 bit ADC and
proprietary clamp and gain controllers and
utilizes 4H comb filter for separating luminance
& chrominance to reduce cross noise artifacts.
The TW2866 adopts the image enhancement
techniques, such as IF compensation filter, CTI
and programmable peaking. TW2866 also
includes one NTSC/PAL video encoder with two
10 bit DAC’s to support CVBS and YC output. The
TW2866 also includes audio CODEC, which has
five 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 …
