    • The recording operation can be rapidly started and a notification about the operating state during the recording operation can be realized without adding a new component, whereby a target scene of a subject can be recorded reliably. When a video signal captured by a camera unit 10 is compressed and encoded and is recorded on a DV tape, a control unit 100 controls a compression/decompression unit 40 and a tape deck unit 60 to compress and encode the video signal and record as DV data without using compressed data already recorded on the DV tape. In other words, the control unit 100 controls the operation of compressing and encoding video data to be newly recorded in such a manner that compressed data already recorded on the DV tape is not read out, thus reducing the time until recording of the video data on the DV tape is started.
    • 可以快速开始记录操作,并且可以在不添加新组件的情况下实现关于记录操作期间的操作状态的通知,从而可以可靠地记录被摄体的目标场景。 当由摄像机单元10拍摄的视频信号被压缩和编码并被记录在DV磁带上时,控制单元100控制压缩/解压缩单元40和磁带机组单元60来压缩和编码视频信号并记录为DV 数据不使用已经记录在DV磁带上的压缩数据。 换句话说,控制单元100控制压缩和编码要被新记录的视频数据的操作,使得已经记录在DV磁带上的压缩数据不被读出,从而减少直到记录视频数据的时间 DV磁带启动。

    • A radio telephone system comprises a base unit electrically connected to a wire telephone line and at least one radio telephone set which can be connected to the base unit through a radio communication line. A predetermined threshold value is normally set for the intensity of a received electric field generated in the radio line so that, when the received electric field intensity does not reach the threshold value, for example when the radio telephone set is separated by more than a predetermined distance from the base unit, the radio communication line is automatically cut off. In the radio telephone system, the threshold value for the received electric field intensity can be arbitrarily modified by means of a suitable operating member disposed in the radio telephone set to thereby increase the flexibility of the radio telephone system. The operating member can comprise, of course, an exclusive key switch, a pushbutton switch or the like, or alternatively a dial key or the like previously provided in the radio telephone set may be commonly used also as the operating member.
