Abstract: Other receivable subchannels S in addition to a major channel M and a subchannel S in selection now are displayed. Further, the subchannel S in selection now is differentiated (for example, changed in color) from the other receivable subchannels S to be displayed.

Abstract: When a digital broadcasting channel and an analog broadcasting channel, over which the same program is currently being transmitted, are provided by a broadcasting station, upon each depression of a digital/analog switching button on an operating unit, an MPU alternately switches between the digital broadcasting channel and the analog broadcasting channel across which the program is being transmitted. And when the current broadcasting station provides a digital broadcasting channel and an analog broadcasting channel across which the same program is currently being transmitted, the MPU alternately switches between a predetermined digital broadcasting channel and a predetermined analog broadcasting channel.

Abstract: When high speed reproduction of digital video information recorded on a DVD which is a record medium is performed at n-fold (n≧3) speed, by operating a high speed reproduction key of a remote control, an expansion unit is controlled by a control unit and a picture of one frame every several frames corresponding to n-fold speed reproduction is reproduced and subsequently normal reproduction of pictures of a required number of frames is sequentially performed.

Abstract: A discharge gap device which is provided between an antenna input terminal or a secondary side earth and a commercial power source, or between the power lines of a commercial power source as a ground discharge countermeasure for electrical equipments such as a television set, a video cassette recorder, and a television and video compound device. The discharge gap device functions only as a discharge gap unit and has two conductors. Normally, the conductors are not electrically connected to each other, and upon application of over-voltage, discharge occurs between the conductors; that is, the conductors are electrically connected to each other.

Abstract: An automatic receiving channel setting method of the receiver having a receivable signal strength, judges whether or not the detected channel is included within the frequency zone allotted only to the CATV, sets the receiving mode, and searches and memorizes the channel according to the allotted channel plan of the CATV or sets the receiving mode of the receiver to the TV receiving mode of the ground wave and searches and memorizes the channel according to the allotted channel plan of the TV broadcast of the ground wave.
