Abstract: To ensure wireless transmission among respective communicating apparatus when constructing a local area network with a plurality of wireless communicating apparatus. Under the control of control station (10), a wireless signal of frame structure is transmitted between communicating stations (20) and (30). The wireless signal of frame structure has a managing region and a data transmitting region. In the managing region, a test signal for checking quality of communication among a plurality of communicating stations and communication quality information representative of quality of communication among the plurality of communicating stations are transmitted. In the data transmitting region, isochronous data or asynchronous data is transmitted under the access control of the control station.

Abstract: A playback device (10) generates a PN code (15) with a start timing based on a video sync signal (14), and generates a PN inverse code (16) which has a reverse polarity to that of the PN code with a timing based on the video sync signal (14). An anti-duplication control signal (13) is spectrally spread (17) using this PN code, superimposed on the video signal (18) and supplied to a recording device. A PN inverse code which is the same as the PN inverse code used in the playback device is also generated in the recording device based on the video sync signal, and reverse spectral spread is performed using this PN inverse code.

Abstract: An offset value corresponding to the difference between counter values of cycle time counters in two buses is obtained. The offset value is stored. When the buses are connected, the value of a first cycle time counter is compensated for an offset value. The counter value of the first cycle time counter is compared with the counter value of a second cycle time counter. A time stamp of data is changed corresponding to the offset value.

Abstract: When an information signal recorded in a magnetic card is updated by an information recording and updating apparatus, a spectrum spread signal corresponding to the updated information signal is generated and it is then recorded superimposing to the information recorded previously in the magnetic card without erasing the old information. Since the information is spectrum spread, alternation is difficult. Moreover, the magnetic card may be discriminated whether it may be used or not by considering the old information recorded in the magnetic card when it is used.

Abstract: A playback device generates a PN code sequence which repeatedly generates with a predetermined period video in synchronism with a video sync signal. An anti-duplication control signal is spectrally spread using this generated PN code sequence, superimposed on the video signal and output. A PN code sequence having the same timing and code pattern as the PN code sequence used in the playback device is similarly generated based on the video sync signal on the receiving side which receives the output video signal. using this PN code sequence, reverse spectral spread is performed, the anti-duplication control signal superimposed on the video signal is extracted, and anti-duplication control is performed according to the extracted anti-duplication control signal.
