    摘要: A rate conversion apparatus 10 includes a quantization parameter setting unit 107 and a rounding threshold value setting unit 108. The quantization parameter setting unit 107 determines a quantization parameter change amount according to a code amount of encoded data output from a variable length encoding unit 109 and a target code amount. The quantization parameter setting unit 107 adds a first quantization amount used in an image before conversion to the quantization parameter change amount, to generate a second quantization parameter to be used in re-quantization processing in a quantization unit 105. The rounding threshold value setting unit 108 sets the rounding threshold value according to the quantization parameter change amount. The quantization unit 105 performs re-quantization using the second quantization parameter and the rounding threshold value.

    摘要: Retransmission control and retransmission are performed at a lower priority than the transmission of multicast packets from a transmission apparatus to two or more reception apparatuses. A communication apparatus performs wireless multicast transmission to reliable transmit packets. In a transmission side terminal, sequence numbers are attached at a layer higher than the Mac layer to each of secured-bandwidth or priority control-type Mac layer multicast packets, and in a plurality of reception side terminals, missing packets are detected using the sequence numbers, and bandwidth other than the secured bandwidth or lower priority packets are used to perform retransmission requests. The transmission terminal retransmits data using bandwidth other than the secured bandwidth or lower priority packets, thereby enabling favorable reception of audio, video and data when transmitting the audio, video and data in real-time to the reception terminals using wireless secured bandwidth-type or priority control-type Mac layer multicast transmission.

    摘要: In serial transmission of a mixture of isochronous data and anisochronous data, communications through a transmission path with a high ratio of occurrence of transmission errors may disturb images during streaming reproduction and produce noise in sound. To solve this problem, the isochronous data that has not been successfully received is retransmitted by using an anisochronous region. Thus, a transmission error of the isochronous data can be reduced without impairment of isochronous characteristics of the data.
