摘要： Herein described is a system and method of detecting 2:2 and/or 3:2 pull-down video. In addition, aspects of the present invention provide a system and method to identify and lock onto a field phase of a received 2:2 or 3:2 pull-down video signal. The system for detecting a field phase in 2:2 pull-down video comprises a first circuitry that computes unexpected motion values, a second circuitry that implements an alternating straight through or crossover function, a third circuitry that performs processing and generates one or more control signals, a pair of counters, and a phase selection circuitry. The method comprises computing luminance approximations of pixels associated with an output video frame, computing one or more first differences, and computing a second difference for each absent pixel of the output video frame based on one of five field phases.

摘要： A system for generating a digital representation of a video signal comprised of a sequence of video frames which each include two video fields of a duration such that the video plays at a first prespecified rate of frames per second. The sequence of video frames includes a prespecified number of redundant video fields. Redundant video fields in the video frame sequence are identified by a video processor, and the video frame sequence is digitized by an analog to digital converter, excluding the identified redundant video fields. The digitized video frames are then compressed by a video compressor to generate a digital representation of the video signal which plays at a second prespecified rate of frames per second.

摘要： A system and method for bad weave detection for inverse telecine. To detect a bad weave artifact, the number of reversals of the difference polarity between successive lines within a column of samples is counted. The count of the number of reversals of the difference polarity is referred to as the polarity change count. In the execution phase, the polarity change count can be used by a bad weave detector to take a system out of lock. The polarity change count can also be used during the detection phase to detect a particular cadence.

摘要： A method for detecting moving interlaced text in a video sequence originating through telecine is disclosed. The method generally includes the steps of (A) checking a motion condition of a current block in a current field in the video sequence for motion both (i) from a previous field in the video sequence to the current field and (ii) from the current field to a next field in the video sequence, (B) checking an artifact condition of the current block for a plurality of symmetric interlaced artifacts in both (i) a forward temporal direction and (ii) a backward temporal direction and (C) asserting a block motion indicator for the current block if all of (i) the motion condition is true and (ii) the artifact condition is true.

摘要： A system and method of optimizing transmission of a program to multiple users over a distribution system, with particular application to video-on-demand for a CATV network. The system includes, at a head end of the CATV network a scheduling and routing computer for dividing the video program stored in long term fast storage or short term fast storage into a plurality of program segments, and a subscriber distribution node for transmitting the program segments in a redundant sequence in accordance with a scheduling algorithm. At a receiver of the CATV network there is provided a buffer memory for storing the transmitted video program segments for subsequent playback whereby, in use, the scheduling algorithm can ensure that a user's receiver will receive all of the program segments in a manner that will enable continuous playback in real time of the program. Under the control of controller the receiver distinguishes received program segments by a segment identifier so that redundant segments captured in capture memory are then stored in buffer memory from which the segments can be retrieved and decompressed in data compressor for immediate or subsequent viewing. In one embodiment, the method of this invention includes dividing at least some segments into fragments, and transmitting one fragment of each segment during a playback interval of a duration, for example, equal to a playback time of a segment.

摘要： A method for a 3:2 pull-down film source detection. First, a source is received. Then, field differences of two fields of the same type in the source and an average field difference according to the field difference corresponding to at least one prior field in the source are calculated. The source is established as a 3:2 pull-down film source by checking whether a 3:2 pull-down signature is in the source according to the field difference and the average field difference, and a bad editing point is detected according to an interlaced frame information of the source.
