摘要： On the occasion of stopping the tape running at a high speed, a winding radius of the tape supply reel is detected to set the tape deceleration rate (a) on the basis of the detected winding radius of the supply reel. After the tape running speed is decelerated up to the allowable speed VL in the predetermined deceleration rate (a), the tape is stopped by effectuating the brake. Thereby, the tape can be driven at the speed higher than the allowable speed VL without generating any damage, enabling reduction of time required for the fast-forward/rewind operation. This can improve application flexibility by providing a couple of tape running modes at the first high speed V1 which is higher than the allowable speed VL and the second high speed V2 which is lower than the allowable speed VL. In addition, running of the tape can be ceased within the predetermined time t from the input of the stop command signal by specifying the maximum speed Vmax depending on the preset deceleration rate (a) and limiting the tape running speed with the maximum speed Vmax.

摘要： On the occasion of stopping the tape being run at a high speed, a winding radius of the tape supply reel is detected, and a tape deceleration rate is set in response to the detected winding radius. After the tape running speed is decelerated in the deceleration rate up to a preset speed, VL, at which the tape being run can be stopped without damage, the tape is stopped by a brake means. Thereby, the tape can be driven at a higher speed than the speed, VL, without damage, enabling a reduction of time required for a fast forward/rewind operation.

摘要： A video recording/reproducing apparatus capable of discriminating commercial message portions even when a broadcasting mode is the same. A magnetic head records television broadcasting signals to a magnetic tape and reproduces the television broadcasting signals from this magnetic tape. When the television broadcasting signals are reduced by recording/reproducing apparatus, an audio-free portion detector detects audio-free portions from audio signals in the television broadcasting signals. Commercial message (CM) portion detector detects the commercial message portions in the television broadcasting signals by the time intervals among a plurality of audio-free portions detected by the audio-free portion detector, and a CM information memory circuit stores the information of the recording positions of the commercial message portions detected by this commercial message portion detector to the magnetic tape. When the television broadcasting signals are reproduced from the magnetic tape, reproduction is carried out while the commercial message portions are skipped, at the recording positions of the commercial message portions to the magnetic tape, on the basis of the information of the recording positions of the commercial message portions to the magnetic tape that are stored in the memory circuit.

摘要： When a video signal reproduced by a helical scan type video signal reproducing apparatus is displayed on the screen of a liquid crystal matrix circuit, a change in brightness on the screen is eliminated in a mode for displaying a trick reproduced image such as a noiseless search image, a still image or the like with respect to a mode for displaying a normally reproduced image, thus providing the user with displayed images causing a less feeling of strangeness. During normal reproduction, where a video signal is continuously written into a liquid crystal display circuit, the brightness of the liquid crystal display circuit is controlled based on the value in a reference brightness register set by the user. During trick reproduction, where a video signal is discontinuously written into the liquid crystal display circuit, the liquid crystal display circuit is controlled to display an image relatively darker than the value in the reference brightness register. This eliminates the difference in brightness between a normally reproduced image and a trick reproduced image, thereby allowing the user to have a less feeling of strangeness.
