Videosignalübertragungssystem und -verfahren zur Kodierung von Videosignalen

摘要

In a video signal transmission system, in which video signals are transformed to high efficiency coded data and are then transmitted, a quantization step size is enlarged in quantizing picture data intra coded to be effectively avoided the amount of data generated excessively increasing. The data residual amount of transmission buffer memory is set to a small level as compared to the data residual amount at which the frame dropping is completed. Video signals which are intra coded are then sent immediately after a transmission line is connected to a destination to be enhanced in facility. <IMAGE> <IMAGE>
