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.
摘要翻译：切换通道所需的时间可以大大减少。当通过具有OFDM系统的多个信息信道广播信号时，多个信息信道在频率上被多路复用，并且对于所连接的发送集中地进行IFFT调制，而不是独立地对多个信道进行OFDM调制以进行传输。通过这种安排，提高了频率利用的效率。根据本发明，为了连接传输的目的，为每个信息信道同步OFDM帧。然后，OFDM接收机可以切换用于信号接收的信道，保持帧同步信号。

摘要： A radio relay system (1) comprises a wireless camera (11) and a signal receiving relay station (12). The wireless camera (11) wirelessly transmits signals to the signal receiving relay station (12) by using the OFDM modulation method. The wireless camera (11) and the signal receiving relay station (12) perform energy dispersion at the time of transmission-line-coding/decoding a transport stream. The PRBS seed (initial value) to be used for the energy dispersion can be externally modified and the user can arbitrarily select a value for the seed.

摘要： An operation processing apparatus adapted to perform a data conversion on input bits has a logic circuit adapted to perform a data conversion on input bits. The logic circuit includes selectors configured in a hierarchical layer structure and controlled by select signals corresponding to the input bits. Constant values input to selectors located in a bottom layer of the hierarchical structure are selected and transferred toward a top layer from one layer to another. A constant value is finally selected and output from the top layer. The data conversion process is controlled by a control unit such that a pre-charge phase and an evaluation phase are performed alternately. In the pre-charge phase, all input values to the selectors are set to be equal. In the evaluation phase, an output bit for given input bits is produced. The select signals are switched in the pre-charge phase.
