摘要： Superimposed FM data is demodulated to digital data. A synchronism reproducing circuit (data block detecting section) detects the front of blocks in the digital data to generate a block head signal (a station change timing signal), which is supplied to a control section of a station selecting microcomputer. When a station selecting key requests a change of the received station, station data corresponding to a requested station is supplied to the control section (a station selecting control section). When the block head signal is inputted after requesting the change of the station, the control section begins to output station change data to a PLL frequency synthesizer in order to change the frequency signal in a front end. This prevents a latter part of a block in received superimposed FM data from being NG data.

摘要： An FM broadcasting signal carrying multiplex character data transmitted from a radio broadcasting station is automatically preset in an FM receiving apparatus. An FM broadcasting signal is received, and a frequency information of the received FM broadcasting signal is temporarily memorized in a memory. It is judged whether a PLL lock signal is produced by a clock signal reproducing circuit during a demodulation process of the FM broadcasting signal whose frequency information is memorized in the memory. When it is determined that the PLL lock signal is produced by the clock signal reproducing circuit, it is determined that the FM broadcasting signal carries multiplex character data, and the frequency information of said FM broadcasting signal is preset to the FM receiving apparatus.

摘要： Method and apparatus for transmitting an information signal generate a plurality of block signals on the basis of the information signal, generate a plurality of parity block signals on the basis of the plural data block signals, generate a frame signal containing the plural data block signals and the parity block signals, and send out the frame signal. Each of the data block signals includes a first block synchronizing signal indicating the start of the data block signal, a data signal containing the information signal and a first parity signal derived by encoding the data signal. Each of the parity block signals incudes a second block synchronizing signal indicating the start of the parity block signal, a second parity signal and a third parity signal. Bit signals located at same bit positions in the respective second parity signals are derived by encoding bit signals located at the same positions in the respective data signals. Bit signals located at same bit positions in the respective third parity signals are derived by encoding the bit signals located at the same bit positions in the respective first parity signals or alternatively the third parity signal in each parity block signal is derived by encoding the second parity signal in each parity block signal.

摘要： A CPU enables an FM tuner, a tuning controller and an FM multiplex decoder, after which the CPU is disabled. The FM tuner, tuning controller and FM multiplex decoder receives frame data including emergency information transmitted from a broadcasting station. When a packet coincidence circuit determines that the received block is a specific block which may include emergency information, the FM multiplex decoder causes an emergency information determining circuit to determine if the associated packet contains emergency information. If this packet contains emergency information, the emergency information determining circuit sends an interrupt signal to the CPU to enable the CPU. The CPU then reproduces the emergency information in the received data and displays it on a display section.

摘要： Received data is applied in units of blocks to an error correcting unit and a data holding unit. If the error correcting unit normally performs error correction, the output from the error correcting unit is stored in a frame buffer. If the error correcting unit does not normally perform error correction, the data in the data holding unit is stored in the frame buffer. In this manner the first error correction processing is performed. Bit data is sequentially read out in units of bits from each block stored in the frame buffer, subjected to the second error correction processing, and returned to the frame buffer. The third error correction processing is further performed for the data sequentially output in units of blocks from the frame buffer.

摘要： An SI judging circuit in a service detecting section detects a service identification code included in a block included in received superimposed FM data. When the block represents an unnecessary service, the SI judging circuit generates a predetermined service detecting signal, which is supplied to a station selecting microcomputer. A user operates a station selecting key to request the change of the broadcasting station. When the change is requested, and also the service detecting signal indicating that the service included in the received block is not needed is supplied to the station selecting microcomputer by the SI judging circuit, a control section of the station selecting microcomputer outputs station data corresponding to the requested station to a PLL synthesizer, and then the frequency signal (tuning frequency) is changed at a front end. This enables data received during a period for receiving blocks for unnecessary services to be NG, and can prevent data of blocks including necessary services from being NG.
