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.

摘要： A transmission and reception system includes a transmission apparatus for transmitting content and a reception apparatus for receiving the content. The transmission apparatus includes a coding section that codes the content into hierarchy codes and outputs coded data of a plurality of layers, a packet generation section that generates packets including the coded data and a timestamp and outputs packets from low-level information of the coded data, and a transmission section that transmits the packets. The reception system includes a reception section that receives the packets, a holding section that holds the packets, a writing control section that controls the writing of the packets, and a determination section that determines whether there is packet loss in the packets. When there is packet loss, the writing control section writes the packets received up to a time of packet loss based on a timestamp in the packets.

摘要： The present invention relates to a transmission and reception system, a transmission apparatus and transmission method, a reception apparatus and reception method, a recording medium, and a program in which, even when received image data has defects, a good-quality image can be displayed. A reception control section 147 detects a loss from image data received by a communication section 141 and permits reception according to the loss. When reception is permitted, the communication section 141 holds the image data in a buffer. A decoder control section 152 permits decoding according to a threshold value held in a threshold-value holding section 151. When decoding is permitted, a decoder 143 decodes the image data held in the buffer 142 and holds the data in a frame memory 144. A display control section 145 controls a display section 146 so as to display an image in accordance with the image data held in the frame memory 144. The present invention can be applied to an image distribution system.

摘要： This invention relates to a transmission controlling apparatus, a transmission controlling method, a recording medium, and a program for instantaneously transmitting data while averting a so-called slow start. Video data acquired by a picture acquisition unit 21 is input to an initial rate determination unit 24 and a picture encoding unit 22 as outgoing data. An acceptable picture quality determination unit in the initial rate determination unit 24 determines a minimum acceptable picture quality acceptable to a user who views the video data sent from a transmission unit 11. A transmission rate determination unit in the initial rate determination unit 24 determines as an initial transmission rate the transmission rate that meets criteria for the minimum acceptable picture quality supplied from the acceptable picture quality determination unit, and forwards the determined rate to a rate control unit 25. In turn, the rate control unit 25 controls the transmission rate for a transmission unit 23 so that the unit 23 starts to send video data at the initial transmission rate supplied from the transmission rate determination unit 44. This invention applies illustratively to transmitting apparatuses for transmitting predetermined data.
