VIDEO DIGITAL DATA TRANSMITTER

摘要

PURPOSE:To provide the video digital transmitter provided with an error check correction means and a means multiplexing video digital data onto an STM frame. CONSTITUTION:A video digital data transmitter 101 at a sender side outputs video digital data coding data resulting from a video parity bit to video digital data, and an STM framer section 106 multiplexes video digital data coding data onto an STM frame. An STM de-framer section 108 at a receiver side multiplexes/demultiplexes video digital data coding data from the STM frame and a video digital data receiver 109 implements error check and correction. Thus, the quality of video digital transmission is secured and the video digital data are sent through a broad band ISD network.
