    摘要: The system of the present invention includes a sending studio where a motion picture soundtrack is produced and a receiving studio where the motion picture is viewed while the soundtrack is transmitted from the senior studio. The system includes communications terminals at both the sending and receiving studios which can translate analog audio-image synchronization and other control or communications signals into an encoded digital signal suitable for long distance transmission and reconstruction without signal loss or serious distortion. The encoded digital is transmitted from one signal studio to another for control and synchronization of the audio and video equipment used to produce the motion picture soundtrack.

    摘要: A video storage and synchronization system has one of more frame memories and an output buffer providing a selectable delay. Incoming video signals are digitized and routed to the memories and/or to the buffer. Stored signals are read out from the memories in synchronism with the incoming signals and can be mixed with the incoming signals before processing in the output buffer.

    摘要: An image transforming device transforms images by transforming video signals into a spatial frequency range, by frame-interpolating the transformed signals in the spatial frequency range and by reversely transforming such signals. In such a device, a portion moving isolated in a frame can be frame-interpolated in such a manner that the isolated motion is dispersed over the entire frame. Thus, even when a frame contains an isolated moving portion, the device can provide a natural image, effectively avoiding degradation of image quality.

    摘要: In a method and apparatus for converting a synchronizing signal received from a controller for controlling a TV camera into a new synchronizing signal, a single frame synchronizing pulse for every two field pulses is generated on the basis of at least a vertical drive signal of the synchronizing signal received from the controller. The new synchronizing pulse which has a level higher than the white level and lower than the black level of a composite video signal generated by the TV camera is injected into a video transmission line connected to the TV camera for synchronizing the latter on the basis of the injected synchronizing pulse.

    摘要: A synchronizer has a 1-field memory and a reset signal generator. The reset signal generator receives a write sync. signal to control the 1-field memory and outputs a write reset signal which adjusts the timing for writing according to a read sync. signal. An image signal written into the 1-field memory in accordance with the timing determined by the write reset signal is thus synchronized with the timing for reading.

    摘要: A method and apparatus for synchronizing a received television signal to a subcarrier locked signal is provided. The apparatus includes a comparison block for determining whether the received television signal and subcarrier locked signal are related by a predetermined fixed frequency relationship and for providing indications of the same, and a signal generation block for dividing down the subcarrier locked signal according to the predetermined fixed frequency relationship so as to provide an output signal which is synchronized with the subcarrier locked signal, and at a frequency determined according to the fixed frequency relationship when the signals are related. The apparatus is particularly useful in PIP applications where the received television signal is a horizontal signal and the subcarrier locked signal is a four times multiple of the subcarrier frequency. The comparison block preferably includes a counter and a windowing circuit for determining whether edges of horizontal signal pulses are received within or outside a predetermined time window, and a decision circuit for determining whether the occurrences (counts) of in and out of window edges are indicative of related or unrelated signals. The entire apparatus preferably includes only flip-flops, simple logic gates such as AND, NAND, or OR gates, inverters, multiplexer switches, and resettable counters. The apparatus also preferably further includes a standard combination of flip-flops and a NAND gate for providing a synchronized horizontal reset output signal when the comparison block determines that the received horizontal clock and the subcarrier locked clock are not related.

    摘要: A vertical phase adjust circuit with high noise immunity for line locked surveillance cameras. To prevent noise from the AC line producing false output signals, a counter is used to lock out the delayed vertical line locked output signal. The horizontal scan frequency is counted from the time a vertical output is produced, and the vertical output signal is prevented until 98 percent of the period between legitimate vertical signals has elapsed. The circuit also includes a lock detect circuit to increase the time window during startup conditions to assure initial synchronization and an increased phase adjust range to permit synchronization with any other camera.

    摘要: A video signal processing device includes first access circuitry for writing a video signal in a memory capable of storing a video signal of at least two picture frames, and second access circuitry for reading the video signal from the memory. Comparision circuitry then compares a first address accessed by the first access circuitry with a second address accessed by the second access circuitry. The second address is then shifted by the amount of an integer of picture frames in accordance with the result of the comparison either at the moment when the first access circuitry is granted access to the memory or when access of the first access circuitry to the memory is stopped.
