    摘要： A genlock device comprises: means (31) for inputting an external reference signal; means (32,33,34,36,39,40,41,42,44) for generating a master reference clock signal synchronized in phase with the external reference signal; and means (37) for storing a genlock state. The genlock state includes, for example, absence of a synchronization signal in the external reference signal. The genlock device can further comprise: means (45) for storing a voltage value determined so that a voltage controlled oscillator (40) oscillates a signal having a frequency higher or lower by a predetermined value than a reference frequency of the voltage controlled oscillator; and means (44) for judging whether a voltage value which controls the voltage controlled oscillator is larger or smaller than the voltage value.

    摘要： CW lock is conducted with less manual operation. A first input 22 receives a black burst (BB) signal from a key TV station. A second input 30 receives a continuous wave (CW) signal having an accurate, known frequency. A phase adjust signal generator 24 generates a reset signal having a known phase relationship with regard to the key TV station BB signal. The reset signal is used as a phase adjust signal. A PLL 32 receives the CW signal to provide clock. A counter 34 receives the clock and provides a frame pulse signal for synchronizing the key and local TV signals at a local TV station wherein the BB signal of the local station may be derived from the frame pulse signal. The counter 34 uses the reset signal to adjust the phase relationship between the key TV station BB signal and the frame pulse to a desired phase relationship based upon the key TV station BB signal.

    摘要： The present application relates to a method of at least substantially synchronising data output from at least first and second graphics cards (1, 2). A synchronisation difference between the first graphics card (1) and the second graphics card (2) is determined and a correction signal (41) generated based on the synchronisation difference. The correction signal (41) is supplied to the second graphics card and the operating frequency of the second graphics card (2) is adjusted in response to the correction signal (41). The application also relates to a system (100) for processing images.

    摘要： In a transmitting section for a video signal transmitting/receiving system for transmitting digital video signals using a plurality of transmission channels, video guard band signals are inserted into video signals associated with the transmission channels immediately before transition from a blanking region to an effective video region. In a receiving section for the system, the inserted video guard band signals are detected for the respective transmission channels. A skew among the transmission channels is detected based on the detection result. To synchronize the video guard band signals among all the transmission channels, with reference to one of the video signals associated with a transmission channel with the longest delay (i.e., delayed by one clock cycle 1T), a delay of 1T is given to the other video signals. As a result, even if a skew occurs among the transmission channels, correct pixel data is displayed.

    摘要： An invention for measuring, maintaining and correcting synchronization between signals which suffer varying relative delays during transmission and/or storage is shown. The preferred embodiment of the invention finds particular use in measuring the relative delay between multiple audio signals and an associated video signal of a television type program which is compressed via MPEG or other compression for a transmission and/or storage system. The invention marks the video signal at a time when a particular event in the associated audio occurs. The mark is carried with the video throughout the video processing. After processing the same event in the audio is again identified, the mark in the video identified, the two being compared to determine the timing difference therebetween.
