摘要： In a network including at least two transmission paths whose bands are respectively managed, an RTT test of DTCP-IP may fail due to a relay wait time generated by the band management regardless of retrials. An objective of the present invention is to assure success of the RTT test. A master unit device manages bands of the transmission paths and includes an RTT test detection section detecting a failure of the RTT test, and a band management section modifying a band management (TXOP allocation) schedule based on an RTT test failure detection. With this configuration, a time band during which no TXOP is allocated is provided between the transmission paths whose bands are respectively managed, thereby assuring success of the RTT test.

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 time-base inversion type linear phase filter, an input signal is time-base inverted, and thereafter delayed. The delayed signal is time-base inverted back to the original time sequence and then filtered by a first IIR filter. First and second selectors alternately select the time-base inverted signal and the delayed signal in opposite phases to each other. Output signals of the selectors are filtered by second and third IIR filters and then alternately selected by a third selector. An output of the third selector is time-base inverted back to the original time sequence and added to an output of the first IIR filter. A nonlinear emphasis/de-emphasis apparatus is constituted by using this linear phase filter.

摘要： A wireless receiver including receiving antennas, frequency-space transformers, noise wave removers, a back-end signal processor, a pattern detector, a broadcast interruption detector, and a back-end controller. The frequency-space transformers convert signals received by the antennas into frequency-space signals. The noise wave removers each at least perform the calculation of a transmission line coefficient matrix and the calculation of an inter-antenna covariance matrix on the frequency-space signals. A controller controls the back-end signal processor to operate when the multicarrier transmission waves have been detected to be interrupted. The noise wave removers each perform the calculation of the inter-antenna covariance matrix when a broadcast interruption detector has detected the interruption of the multicarrier airwaves. Thus, the wireless receiver removes noise generated within it, thereby having high reception sensitivity.

摘要： A transmission device (100) outputs, to a reception device (200), a stored amount of packets in a first transmission buffer (105) just before a certain packet has been written to the first transmission buffer. A first reception buffer amount read unit (206) in the reception device reads a stored amount of packets in a first reception buffer just before the certain packet has been read from the first reception buffer. A storage amount addition unit (207) adds the stored amount of packets in the first transmission buffer and the stored amount of packets in the first reception buffer, and a correction unit (208) adjusts the frequency of a variable frequency oscillator in a reception timestamp timer 209 so that the resulting added value is a constant value.

摘要： The present invention is built on a time out control apparatus to control the time out when a packet is transferred between terminal units connected to different buses. In the time out control apparatus, delay measuring means measures the delay time required for a response packet to be received after a request packet is sent to a terminal unit (control unit) connected via a bus. Delay information list generating means generates a delay information list in which the delay times measured by the delay measuring means are related to the individual identification information on the respective terminal units. Information output means reads out the delay time from the delay information list in accordance with a request from the terminal unit and outputs the delay time to the terminal unit. This sets the delay time on the time out register of the terminal unit.
