Abstract
Disclosed is a digital data transmission system comprising a transmission apparatus and a reception apparatus. The transmission apparatus generates error location information at which an error occurs in each block, in accordance with a data signal including a video signal composed of a first number of words and generated for each block, and an error information signal indicating presence or absence of an error corresponding to the data signal, multiplexes the generated error location information and the data signal into a multiplexed signal, and then, transmits the multiplexed signal through a transmission line. On the other hand, the reception apparatus receives, through the transmission line, a transmission data signal including a data signal including a video signal composed of a predetermined first number of words and generated for each block and an error pointer signal indicating error location information corresponding to the data signal, demultiplexes the received transmission data signal into the data signal and the error pointer signal, and generates error information indicating presence or absence of the error corresponding to the data signal, in accordance with the error pointer signal. The data signal is decompressed in accordance with the generated error information, and this leads to reduction of occurrence of errors.
