摘要： A signal processing apparatus for changing the frequency characteristics of an input signal, e.g.--a video or audio signal, allows a signal to pass through a transmission circuit in a positive time sequence and then, allows the signal to be transmitted through another transmission circuit having the same transmission characteristics in a reverse time sequence with respect to the positive time sequence. Also, while the transmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response direction of the transmission circuit. Accordingly, unwanted wave errors appearing at discontinuous regions of the signals are eliminated.

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： In a video signal recording/reproducing apparatus for emphasizing an input video signal, recording by adding an additional signal necessary for recording, and de-emphasizing when reproducing, the emphasis processing is stopped on the time axis in a period in which the additional signal is to be added. Besides, by adding an additional signal before emphasis processing, the waveform deterioration in the end portion of the effective period occurring due to the addition of additional signal after emphasis processing is decreased, and a favorable waveform reproduction is realized over the entire period of the effective portions.

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.
