摘要： A probe transmitting section (216) in a packet receiving terminal (210) sends a probe packet to a second radio channel (320) at fixed intervals. A probe analyzing section (117) in a packet sending terminal (110) detects a burst loss on the basis of a state of reception of the probe packet. When a burst loss detection is detected, a predictive retransmission control section (118) predicts that a data packet transmitted during the period of the detected burst loss among data packets sent from a priority processing transmission buffer (115) to a first radio channel (310) is a data packet lost on a receiving side, reads the data packet from a retransmission buffer (114), and then sends the data packet to the priority processing transmission buffer (115). A real-time property can be ensured while a packet loss is overcome in a radio environment.

摘要： The present invention relates to an information processing device and method, and program, whereby unnecessary standby time can be reduced in depacketizing processing, and processing can be performed easily and at high speed. A common header creating unit 203 creates common headers which are headers added in common to each packet created, based on a precinct header 171 which the data acquisition unit 201 has acquired, from the precinct thereof. A fragment processing unit 208 divides encoded data which the data acquisition unit 201 acquires into every packet size, in the event that the data size of the precinct is greater than the packet size. A packetizing unit 209 packetizes the payload supplied from the fragment processing unit 208 using header information supplied from each unit, and appropriately sets the value of flag information such as SFF and M included in the common headers of each packet that has been generated. The present invention can be applied to an encoding device, for example.

摘要： An information processing apparatus and method for reducing an unnecessary waiting time in a depacketizing process and enabling processing to be easily performed at high speeds applicable to, for example, an encoding apparatus. An analysis unit compares input image data with image data of one previous picture read out from a storage unit. On the basis of the analysis result, a concealment header generation unit generates a concealment header that is referred to by a receiving apparatus at the time of an error concealment process. On the basis of the concealment header, a loss analysis unit performs error concealment for the occurrence of a transmission error by suitably using encoded data stored in a storage unit.
