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 when quantizing intra coded picture data to avoid an excessive increase in the amount of data generated. The amount of residual data in a transmission buffer memory is monitored, and frame dropping is initiated when it exceeds a certain predetermined level, but the frame dropping operation is not completed until the amount of residual data falls below a different, smaller predetermined level. Video signals which are sent immediately after a transmission line is connected to a destination are intra coded to enhance system usability.
