    Abstract: Herein described is a system and method for improving the appearance of video by generating an improved 4:2:2 chroma. The system comprises a 4:2:2 to 4:2:0 chroma regenerator that regenerates 4:2:0 chroma given a received 4:2:2 chroma, and a 4:2:0 to 4:2:2 chroma generator that weaves and interpolates the regenerated 4:2:0 chroma to yield an adjusted 4:2:2 chroma. The system further comprises a blending system used for blending the adjusted 4:2:2 chroma with the received 4:2:2 chroma based on a control input provided by a motion indication signal. The method comprises regenerating a 4:2:0 chroma from a received 4:2:2 chroma using an algorithm. The method further comprises generating an adjusted 4:2:2 chroma using the regenerated 4:2:0 chroma using another algorithm.

  • Publication number: 20070070244
    Abstract: A method and system for reducing the appearance of jaggies when deinterlacing moving edges in a video processing system are provided. The method may comprise detecting the direction of an angled edge in an interlaced video image to determine a filtering direction to be used for approximating absent pixels in deinterlacing the interlaced video. In detecting the direction of the angled edge, a group of windows of different sizes may be used to look at the edge, where a missing pixel is the center of each of the windows. Detecting the direction of the edge, and therefore the direction of filtering, may comprise: determining the angle associated with the edge, determining the strength of the edge, examining the pixels surrounding the absent pixel, and adjusting the first angle measure and the second angle measure based on the pattern of the surrounding pixels.

  • Publication number: 20060077295
    Abstract: A system and method that convert a video source from a first rate to a second rate. The system may have as an input a video that may be frame-based or field-based at a first rate, and convert the input video to an output video that may be frame-based or field-based at a second rate. The first rate may be 50 Hz and the second rate may be 60 Hz. Converting from the first rate to the second rate may comprise repeating frames or fields. For example, when converting from a frame-based 50 Hz input video to a frame-based 60 Hz output video, the output video comprises frames where every sixth frame is a repeated version of the preceding frame.

  • Publication number: 20060078293
    Abstract: A system and method that repeat video images in a deinterlacing system. The method comprises detecting a signal requesting an input video image be repeated and determining the desired number of repetitions. The input video image may then be processed to generate an output video image and the output video image may be repeated the desired number of repetitions. The input video images following the repeated image may be held until the repeating is completed, and may then be processed and displayed. Repeating the video image may be utilized to achieve different playback modes such as, for example, slow motion, pause, and video rate conversion.

  • Publication number: 20060072037
    Abstract: Herein described are at least a system and a method of more effectively detecting and correcting irregularities when performing an inverse telecine deinterlacing of pull-down video. These irregularities may be caused by editing of the video, which when left undetected, may result in displaying video of unacceptable quality. In a representative embodiment, the method determines a first pixel luminance of an absent pixel using a luminance generated from one or more first present pixels, determines a second pixel luminance of the absent pixel using a luminance generated from one or more second present pixels, and determines a first luminance approximation for the absent pixel. In a representative embodiment, the system comprises a memory, a software resident in the memory, and a processor used to execute the software, such that executing the software performs the inverse telecine deinterlacing to result in an improve displayed video image quality.

  • Publication number: 20050168634
    Abstract: In a video system, a method and system for control of a multi-field deinterlacer including visually pleasing start-up and shut-down are provided. During a hard start, a deinterlacer may deinterlace a first received field and provide the resulting frame for display until sufficient fields are received to generate a pixel constellation for deinterlacing subsequent received fields. The deinterlacer may also provide a constant frame for display until sufficient fields are received to generate the pixel constellation. During normal operation, the deinterlacer may mitigate the effects of a discrepancy as to the received field type. When a video source is jittery or there is uncertainty as to the field type, deinterlacing may be forced to be based on spatial information. When a video source is shut off, a portion of the remaining stored fields may be flushed. At least one of the flushed fields may be deinterlaced and displayed.

  • Publication number: 20050168653
    Abstract: Aspects of the present invention may be found in a system and method to more effectively detect and correct irregularities of video in a pull-down video signal, such as a 3:2 (or 2:2) pull-down video signal. Various aspects of the present invention provide a system and method to determine when the cadence of pull-down video has changed. This may occur, for example, when a bad-edit is encountered in the pull-down video. Other aspects of the present invention may be found in a system and method of detecting and correcting distortion or artifacts occurring at the pixel level. The distortion or artifacts are detected and corrected at a per-pixel level while performing a reverse pull-down of the video signal. Finally, aspects of the invention allow the automatic enabling of per-pixel correction when performing a reverse 3:2 directed weave. A computed variable is used to automatically activate the per-pixel correction.

  • Publication number: 20050168655
    Abstract: In a video system, a method and system for pixel constellation in a motion detection deinterlacer are provided. An output pixel in an absent line of a current frame may be determined based on a constellation of pixels from at least one present line above and at least one present line below the absent line. The present lines may be immediately above and/or below the absent line. Pixels from the present lines immediately above and/or below include the pixel directly above and/or below the output pixel and/or at least two pixels to either side. The output pixel may also be determined from present lines in fields that occur prior to and/or after the current field. The fields may be those that occur immediately before and/or after the current field and/or the second and third field that occur after the current field.

  • Publication number: 20050168632
    Abstract: A system and method that scales interlaced video fields with different sizes in a deinterlacer. The deinterlacer may expect video fields of a certain size. The input to the system may be a video stream of interlaced content, with fields having different sizes depending on the video content. The method scales the input video fields to the appropriate size expected by the deinterlacer. The expected size of the fields may be programmable. The method may provide an output with the expected size of black pixels in the absence of an input to the system.
