ABSTRACT:
When transmission of on-demand video data interrupts transmission of broadcast video data from a distribution server17to a user terminal18, the distribution server17transmits substitute I frame data to the terminal18after on-demand video data transmission in complete and before resuming broadcast video data transmission. The user terminal18decodes and displays the substitute I frame data, and then uses the decoded substitute I frame data as a reference frame to decode and display the first several frames of broadcast video data received directly after resumption of transmission.
