摘要： In accordance with the present invention, a read clock frequency applied to field memories (16a) and (16b) comprising a converting circuit (16) which converts the field frequency of a video signal is changed at the unit of a vertical cycle whereby vertical cycles of video signals read out from the field memories (16a) and (16b) are made substantially equal to one another. Accordingly, a horizontal deflecting current waveform on which a parabolic wave current of, for example, the vertical cycle is superposed becomes equal during each vertical period so that it becomes possible to prevent a jitter from being produced at right and left ends of a picture screen.

摘要： The time required for switch the channel can be remarkably curtailed. When broadcasting signals through a plurality of information channels with an OFDM system, the plurality of information channels are multiplexed in the sense of frequency and collectively subjected to IFFT modulation for connected transmission instead of subjecting the plurality of information channels independently to OFDM modulation for transmission. With this arrangement, the efficiency of exploitation of frequencies is improved. According to the invention, the OFDM frames are synchronized for each information channel for the purpose of connected transmission. Then, the OFDM receiver can switch the information channel for signal reception, maintaining the frame synchronizing signals.

摘要： An apparatus and method for receiving an OFDM signal arranged to reproduce correct carriers. I channel data and Q channel data decomposed into subcarrier components by FFT processing are differential-demodulated by a differential demodulation circuit to remove an FFT window phase error and a reproducing carrier phase error. In a differential demodulation circuit, a reproducing carrier frequency error and a phase error dependent on a reproducing clock frequency error are removed and only I-axis data is thereafter output to be stored in a RAM with respect each symbol. A pilot signal selecting data generation circuit supplies the RAM with data which is prepared by suitably shifting pilot signal selecting data used as a reference. Resulting Data read out is accumulated by cumulative addition performed by a cumulative addition circuit. A maximum value detection circuit detects a maximum value of the output from the cumulative addition circuit, and the amount of shift of pilot signal selecting data is stored in a reproducing carrier frequency error storage circuit. The reproducing carrier frequency error storage circuit outputs the amount of shift corresponding to the maximum value.
