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.

This invention is an apparatus and method for processing television signals and in particular high quality video type signals in analog or digital form. The preferred embodiments utilizes digital storage along with oversampling, interpolation and various filtering in recursive and nonrecursive form to provide fixed or variably delayed output video signals wherein the artifacts and distortion of the video is kept to low levels.

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.

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.

摘要:
An apparatus and method for tracking dialogue and other sound signals in film, television or other systems with multiple channel sound is described. One or more audio channels which is expected to carry the speech of persons appearing in the program or other particular types of sounds is inspected to determine if that channel's audio includes particular sounds such as MUEVs, including phonemes corresponding to human speech patterns. If an improper number of particular sounds such as phonemes are found in the channel(s) an action such as a report, an alarm, a correction, or other action is taken. The inspection of the audio channel(s) may be made in conjunction with the appearance of corresponding images associated with the sound, such as visemes in the video signal, to improve the determination of types of sounds such as phonemes.
摘要:
Measurement of the relative timing between images and associated information, for example video and audio. Image mutual event characteristics are recognized in the images and associated mutual event characteristics are recognized in the associated information. The image mutual events and associated mutual events are compared to determine their occurrences, one relative to the other as a measure of relative timing. Particular operation with audio and video signals is described.
