8-Channel Video Decoders and Audio Codecs and
Video Encoder for Security Applications
The TW2868 includes eight high quality FN7796
Rev. 3.00
May 22, 2013 п‚ Automatic white peak control analog composite video signal to digital п‚ Programmable hue, saturation, contrast,
brightness and sharpness component YCbCr data for security applications. п‚ Proprietary fast video locking system Each channel contains 10-bit ADC and proprietary п‚ Supports ITU-R BT.656 type time multiplexed
output with 54/108MHz NTSC/PAL/SECAM video decoders that convert clamp and gain controllers and utilizes 4H comb
filter for separating luminance and chrominance
to reduce cross noise artifacts. The TW2868
adopts image enhancement techniques, such as
IF compensation filter, CTI and programmable
peaking. TW2868 also includes one NTSC/PAL
video encoder with two 10-bit DAC’s to support
CVBS and YC output. The TW2868 also includes
audio CODEC, which has ten audio Analog-toDigital converter processing and one Digital-toAnalog converter. A built-in audio controller can
generate digital outputs for recording/mixing and п‚ Provides simultaneous 2x four channel Full D1
with 108MHz and 2x CIF with 54MHz by timemultiplexed output format
п‚ Integrated ten audio ADC processing and one
audio DAC
п‚ Provides multi-channel audio mixed analog
output …
