PI7VD9008ABH
Adaptive EQ 8-channel 960H Video Decoder
General Features
Description
ꢀÎReal time AEQ 8-channel Video/Audio decoder for
PI7VD9008ABH is AEQ 8-Channel Video Decoders and Audio
Codec. Built-in Adaptive equalizer (AEQ) recover the noisy
signals caused by long or small wire gauge Coax cables and
display the best picture image view quality. e video decoder
converts NTSC, PAL analog composite video broadcasting signal
(CVBS) into digital components YCbCr for video controller or
processor to perform pre-view, compression and storage etc. e
converted digital video streams complying with ITU-R BT.656
are transported in time multiplexed format, which contains one,
two or four video channels.
