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. The 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. The converted digital video streams complying with ITU-R BT.656 are transported in time multiplexed format, which contains one, two or four video channels.
