Zusammenfassung:	PROBLEM TO BE SOLVED: To update data on a commodity explanation support device by satellite broadcasting. SOLUTION: A receiving means 3 receives data which are packetized and transmitted. A storage control instruction output means 7 supplies a recording start instruction to a storage means 5 a little before broadcasting start time and supplies a storage end instruction a little after broadcasting end time. The storage means 5 extracts necessary data from the packetized data and stores them when the storage start instruction is supplied and finishes the storage process when the storage end instruction is supplied. A head specifying means 9 once supplied with the storage end instruction specifies a reproduction head frame for reproduction time in the stored data. A reproducing means 11 starts the reproduction at the specified reproduction head frame when a reproduction instruction is supplied.
