PROBLEM TO BE SOLVED: To give a replay function and/or a slow motion function to a receiver for the video contents which are received and projected via a TV set, etc., by using a memory which has a 1st part that receives instantaneously the data and a 2nd part which preserves a data packet that is previously received and displayed and also shifted from the 1st part. SOLUTION: A memory of a receiver has a 1st part which functions as a moving buffer memory part and a 2nd part. The 1st part moves, updated as the time elapses and preserves a data packet that is displayed the latest. When a prescribed time elapses, the 1st part is updated by a later data packet and the data packet so far preserved in the 1st part is shifted to the 2nd part. The 2nd part preserves the data packets in a certain time sequence, and at least a part of duration of the time of determined according to the size of the memory.
