    摘要: This invention is an apparatus and method for digital processing of television like signals and in particular the use of oversampling and interpolation to achieve improved resolution of the digital version of such signals as compared to a digital version obtained by the use of simple A/D conversion or processing at the desired sample rate. The preferred embodiment utilizes oversampling, interpolation and various filtering in recursive and nonrecursive form to provide output video signals wherein the artifacts and distortion of the video are kept to low levels.

    摘要: This invention is a method and apparatus for synchronization high quality video like signals. The preferred embodiment is described to synchronize a plurality of mutually unsynchronized video signals as well as passing one or more associated secondary signal with each video signal with a corresponding delay. The selection of one of a plurality of reference signal candidates is shown along with the use of the input signal to provide a fixed delay.

    摘要: This invention is a method and apparatus for synchronization of high quality video like signals. Full sync tip to peak white video is digitized in the preferred embodiment along with oversampling and interpolation so that errors are kept to unexpected low levels. The preferred embodiment is described to pass one or more secondary signal with the video signal in a separate parallel but time related path. The use of the input signal for a reference to allow a fixed delay is also shown.

    摘要: This invention is a method and apparatus for delaying video type signals along with one or more secondary signals having a timing relationship to the video type signal. The delay maintains the timing relationship between the video type signal nd secondary signals. Operation to mute or otherwise modify the secondary signals upon the loss or corruption of the video type signal is shown. The selection of one of a plurality of reference signal candidates is shown along with the use of the input signal to provide a fixed delay.
