摘要： The running real time length of combined video and audio signal programs is shortened or lengthened by deleting or repeating individual fields or frames and corresponding amounts of audio segments. The video and audio portions of the programming material are separated and subjected to processing through a pair of program time changing units. The video portion is processed by deleting individual fields or frames on a manual, periodic or automatic basis. Manual deletion is done by an operator observing the program material on a monitor. Periodic deletion is performed automatically after the operator specifies the total amount of time (or number of fields or frames) to be deleted, with every ith frame or field deleted regardless of content. Automatic deletion is done in a fashion similar to periodic deletion, but the fields or frames are examined and are deleted on the basis of the amount of between frame motion. Audio segment deletion is done either manually, periodically or automatically, and the audio segments removed need not match the deleted frame video, but may be taken from different frames, so long as the total time length of the deleted audio segments equals the total time of the deleted video frames, and also provided that the differential delay between the processed video and processed audio does not exceed the hip sync criterion. A pause function disables the deletion or insertion process for program materials which may not be altered in any way.

摘要： An input voltage controlled oscillator circuit for a digital video time base corrector used to process television signals to remove time base errors introduced during signal recording, reproducing, or transmission. In the time base corrector, incoming video signals are converted from analog-to-digital form, temporarily stored in a memory unit at a clocking rate which varies in a manner generally proportional to the time base errors, and the stored signals are fetched at a standard clocking rate.The input voltage controlled oscillator circuit generates the clock signals for performing the analog-to-digital conversion and for storing the digital signals in the memory unit. The frequency of the clock signals varies in accordance with the time base errors in the composite sync and burst portions of the incoming video signals.The VCO circuit includes an oscillator for generating an integral multiple of the clock signal train, a first phase lock loop controlled by the frequency of successive composite sync pulses in the incoming video signal, a second phase lock loop controlled by the colorburst portion of successive lines of video information, a gated integrator coupled to the second phase lock loop for integrating successive ones of the VCO control signals generated by the second phase lock loop over a plurality of successive lines of video, and means for enabling the gated integrator during the colorburst portion of successive lines of video.The VCO circuit further includes means for disabling the gating means and the gated integrator when one of the colorburst portions of the video signals lies below a predetermined threshold.

摘要： A sequence control unit for a digital video time base corrector used to process television signals to remove time base errors introduced during signal recording, reproducing, or transmission. In the time base corrector, incoming video signals are converted from analog to digital form, temporarily stored in a memory unit at a clocking rate which varies in a manner generally proportional to the time base errors, and the stored signals are fetched at a standard clocking rate. The sequence control unit controls contemporaneous storing and fetching from different portions of the memory unit and includes circuitry for preventing application of both store and fetch signals to the same memory unit portion when the accumulated time base error would cause such an overlap condition.
