发明名称 METHOD OF CORRECTING TRANSMISSION ERROR IN DIGITAL COLOR-TELEVISION COMMUNICATION SYSTEM AND DIGITAL COLOR-TELEVISION COMMUNICATION SYSTEM TO WORK SAID METHOD
摘要 A method of correcting digital NTSC color-television signals in transmission error by substituting the error-included digital color-television signals with those digital color-television signals in the corresponding horizontal scanning periods two frames periods before, stored in memory (12), and an apparatus to work the method. When a transmission error is detected in a specific horizontal scanning period, substitute circuit (13) reads from memory (12) the digital color-television signals in the N horizontal scanning periods two frame periods before corresponding to the specific and subsequent N-1 horizontal scanning periods, and transmits the digital color-television signals read from memory (12) in lieu of those digital color-television signal in the specific and subsequent N-1 horizontal scanning periods.
