Reception apparatus and method, program, and recording medium |
摘要 |
A reception apparatus and method is disclosed wherein recovery of a lost packet can be performed simply and rapidly in response to the variation of the loss rate. A packet analysis section detects loss of a packet, and a retransmission processing section registers packet information including a sequence number for identification of a packet having been lost into a NACK list. When loss of a packet is detected by the packet analysis section, a NACK production section produces a NACK packet for requesting for retransmission of the non-arriving packet whose packet information is registered in the NACK list. A network inputting/outputting section transmits the NACK packet to a transmission apparatus. The invention can be applied to a reception apparatus which receives, for example, streaming data.
