	Surveillance video tape recorder - Patent 4829389
		A surveillance video tape recorder according to claim 4, wherein said capstan drive means includes adder means connected to receive outputs of said gating means and said capstan speed error detecting means, and an added output of said adder means is supplied to said capstan drive means as a composite error signal.
		To save space on the tape, the tape is held stationary during the actual recording in each track, moved to a new position in anticipation of the recording of the next frame and thereafter held stationery until the recording of a subsequent frame has been completed.
		During the recording of each track, the respective pilot signal may be superimposed, for example, frequency-multiplexed, on a video signal, which is a composite signal formed of a low band converted chrominance signal and an FM modulated luminance signal, and is then recorded with the video signal in the respective track.

	Power feeding and input signal switching control system for video tape recorder combined with television receiver and ...
		A video tape recorder is an apparatus to record video and audio signals in a cassette tape and thereby reproduce the video and audio signals as required, and is certainly one of the most commonly used electronic audio/visual devices nowadays.
		Consequently, the VTR circuit 11 is operated to record the video and audio signals received via the video-in jack 33 and the audio-in jack 34 from the exterior system or reproduce any received video signals via the LCD driver 21 on the LCD device 22.
		Owing to these power connections, the video and audio signals generated in the vidicon 42 and the mike 43 are applied via the select switches 81 and 82 to the VTR circuit 11 to subsequently be recorded in the tape or reproduced on the LCD device 22.

	Digital video tape recorder apparatus - Patent 4577241
		This invention relates to digital video tape recorder apparatus, and is particularly concerned with the regeneration of a clock pulse signal from a stream of data being reproduced by a digital video tape recorder (VTR) from a magnetic tape.
		The VTR 20 has various reproducing modes including in particular a so-called shuttle mode in which the speed of transport of the tape 10 can be varied over a range from a high speed in the reverse direction through zero to a high speed in the normal forward direction.
		The incoming stream of data from the VTR 20 which is supplied to the input terminal 32 is deficient in clock information, and moreover may vary in data rate over a fairly substantial range, in particular when the reproducing mode of the VTR 20 is changed to achieve a special effect.

	Extinct Video Tape Recorder Connectors
		In the TV modes on a portapack VTR, a special 10 pin to 8 pin cable is used to record off air television from the receiver/monitor.
		During dubbing, video would have to be monitored by viewing the record portapack's RF output on a standard TV.
		Since the sync is generated for the camera, and used internally, by the VTR, it is not possible to record external composite video on this recorder.

	G-code decoder for use with a video tape recorder and method for same - Patent 5990966
		A G-code decoder for use with a VTR according to claim 4, wherein said setting means further comprises warning means for sounding one of an alarm and a synthesized voice to indicate the non-setting of the time clock.
		A method of decoding a G-code for use with a VTR according to claim 3, further comprising the step of warning by at least one of i) a sound and ii) a synthesized voice when the non-setting of the time clock is determined in Step (b).
		The present invention relates to a G-code decoder coupled to a video tape recorder (VTR), which is capable of decoding a G-code, and a method for the same, especially for entering the time-setting mode automatically when the G-code is to be decoded while the time is not yet set in the clock.

	Frequency converter for video tape recorder - US Patent 4807048 (Site not responding. Last check: 2007-10-08)
		More specifically, at the time of reproduction of the VTR, a fluctuation component of the time base such as jitter is generally included in a luminance signal and the low-frequency converted chrominance signal due to expansion and contraction of a tape and rotational irregularity of a video head.
		When such a video signal is recorded and reproduced, there is a possibility that displacement and fluctuation of the carrier chrominance signal is compensated for too much or too less.
		Additionally, a horizontal synchronizing signal in the video signal and an output of the LPF 120 are applied to a second phase comparing circuit 121 through a terminal 108 and the 1/D frequency divider 122, respectively.

	Device for switching a video tape recorder head to write/read mode - Patent 5483390
		To achieve this function, while the tape is being recorded, a rectangular signal, having approximately a 25-Hz frequency, is simultaneously recorded by a control head on a control track of the tape.
		Additionally, some video tape recorders use the control signal in order to simultaneously record marks on the tape, which are also referred to as indexes.
		Curve C represents the wave,form of the control signal to be recorded on the tape.
