In the transmission of a moving picture, when the user switches video sources (for example, switches channels or starts reproducing a recorded program), the selected video source can be swiftly started to display. Immediately after a delivery apparatus makes a video source be selected by switching, a receiving apparatus causes a selector to select the video packets transmitted not through an error corrector and to supply them to a decoder and it controls the decoder to generate a frozen frame from the video packets and to supply it to a display where it is displayed. The selector is controlled to produce the error-corrected video data after a counter counts a delay time that the video packets undergo in the error corrector. Thus, the moving picture can be seamlessly displayed, and the delay in the error corrector can be apparently eliminated.
