Abstract

An apparatus to start channel switchover processing with reliability and to shorten an image non-displaying period. The apparatus stores a second channel-selection control information for each channel, including an I-picture appearance time which is a time when a packet including an I-picture is received and an I-pictures appearance interval-time which is an interval between times when a packet including an I-picture is received; and a control unit obtains, after an input of switching of the channel-selection is received, the I-picture appearance time and the I-pictures appearance interval-time corresponding to the switched channel from the channel-selection control information, adds the obtained I-pictures appearance interval-time to the obtained I-picture appearance time, calculates an I-picture appearance estimated-time which is a time when a packet including an I-picture is obtained subsequently, and delays a channel switchover until a time earlier than the I-picture appearance estimated-time by a switchover period-of-time required for the switching of the channel-selection.
