    摘要： A wireless communication system includes a wireless terminal and a plurality of base stations that can communicate with each other via a predetermined communication path that is different from the wireless communication path to the wireless terminal. The wireless terminal transmits a request signal to one of the base stations to request a response signal from another base station. The one base station transfers the received request signal to the other base station via the predetermined communication path. Upon reception of the request signal transferred from the one base station, the second base station transmits a response signal to the wireless terminal via the predetermined channel. The wireless terminal receives the response signal transmitted from the second base station via the predetermined channel.

    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： In a power line communication system, a control device sets an intra-breaker communication period during which communication is performed between communication terminals connected to a single breaker, and an inter-breaker communication priority period during which communication is performed between communication terminals connected to different breakers from each other. The control device operates filters so that the filters allow signals that travel via breakers to pass through the filters during the inter-breaker communication priority period, and so that the filters block signals that travel via breakers from passing through the filters during the intra-breaker communication period.
