摘要： A video tape recorder (VTR) including a detection switch for detecting presence and absence of an erasure prevention tab of a video tape cassette, a light emitting element, a control device associated operatively with the light emitting element, and an electronic viewfinder. When a first video tape cassette provided with the erasure prevention tab as been loaded into the VTR, the control device sets the VTR to a recording standby state and turns on the light emitting element. Meanwhile, when a second video tape cassette which is not provided with the erasure prevention tab has been loaded into the VTR, the control device sets the VTR to a stop state, flashes the light emitting element and causes the electronic viewfinder to display on a screen of the electronic viewfinder a warning indicative of loading of the second video tape cassette into the VTR.

摘要： An apparatus for selecting one of a number of television channels is operable to be set in a mode whereby an array of miniature pictures corresponding to the respective channels is displayed, with each channel being sequentially selected for a predetermined interval during which image data for the selected channel are repetitively written into one of a set of regions (42 to 50) of a one-field memory, with the entire memory contents being continuously and repetitively read out, whereby the picture for the selected channel appears as a moving picture while those of the other channels are static. The apparatus can then be set in a normal operating mode, with the channel selected at the time of mode changeover being thereafter held fixedly selected and a normal display picture produced.

摘要： A battery voltage level detecting apparatus makes possible the detection of the voltage level of a battery and the detection of a minimum operating voltage by means of a single comparison circuit and a single adjustment. A voltage varying with variation of the battery voltage is compared with an output voltage of a counter for counting reference clocks so as to control the counting operation. When a change occurs in the comparison result, a battery voltage level storage command is generated, and then the counter is preset. In response to the command, the count value is stored and displayed.

摘要： A magnetic tape reproducing system for providing a still picture of a slow motion picture. A magnetic tape is provided on which video signals are recorded in successive fields of a unit length in the longitudinal direction of the tape and a plurality of rotary magnetic reproducing heads are placed on the periphery of a rotating disc at equal angular intervals from each other so as to reproduce one complete field of the video signals. The magnetic reproducing heads are arranged so that the distance between the two gaps of two adjacent heads is equal to an integral multiple of the distance along the tape corresponding to a period of horizontal synchronizing signals contained in the video signals.

摘要： A method of processing video signals for eliminating vertical picture fluctuations caused when a video tape recorder reproduces video signals at a tape speed different from that used for recording the video signals. The vertical picture fluctuations are eliminated by substituting distorted vertical synchronous signals for the original vertical synchronous signal, the distorted vertical synchronous signals generated by a processing apparatus having a correction circuit which corrects for the difference in frequency characteristics between the video signal path and the vertical synchronous signal path.
