Introdution
t Doteck DMA serial video/audio digital optic transmitter,output video signal can be CVBS、YUV or half of YC,also can be SDI digital video;input audio signal can be analog audio or digital audio AES/EBU,output system support the DVB SDI digital video signal.
t When the input video signal for CVBS, YUV, YC,DMA can meet user high-quality transmission of analog video and audio signal, digital audio signal requirements, It also can input analog signal and output digital signal. When the input video signal for digital SDI video, DMA can meet user high-quality transmission of digital video and audio signals, analog audio signal requirements, It also can input digital signal and output analog signal.
tInput analog video signal A/D converted into digital SDI signal, input analog audio signal A/D converted into digital signals, AES/EBU both audio signals are then embedded into the SDI digital video signal.
