INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSOR, INFORMATION PROCESSING METHOD, RECORDING MEDIUM AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an information processing system in which an error can be corrected and an idle capacity of a band of a network can be predicted by using an idle region of the band of the network which efficiently transmits/receives information through the network and to provide an information processor, an information processing method, a recording medium and a program.

SOLUTION: A picture transmission device 11 packetizes a plurality of layers of hierarchy encoding data and transmits a packet to a picture reception device 12 in a layer unit. The picture reception device 12 transmits a confirmation response including a transmission time of the packet and ID of the lost packet to the picture transmission device 11. The picture transmission device 11 calculates an optimum transmission rate in accordance with the confirmation response from the picture reception device 12, sets the number of transmission packets based on the transmission rate and sets the layer to be transmitted so that the number of the transmission packets becomes not larger than that which is set. The packets which are wastefully transmitted can be eliminated and communication is made efficient. The invention can be applied to an electronic apparatus connected to the network.
