Abstract
A method for removing MPEG-2 chroma upconversion artifacts in a video stream includes detecting a presence of artifacts in an incorrectly upsampled MPEG-2 video stream and removing the presence of artifacts resulting in an artifact free video stream.
Claims9
A method for removing MPEG-2 chroma upconversion artifacts in a video stream comprising:
- detecting a presence of artifacts in an incorrectly upsampled MPEG-2 video stream and
- removing the presence of artifacts resulting in an artifact free video stream.
A video system for producing a corrected progressive MPEG-2 output from an MPEG-2 compressed video source comprising:
- a) an MPEG-2 compressed video source;
- b) a progressive MPEG-2 decoder having an input coupled to an output of the MPEG-2 compressed video source;
- c) a buffer having an input coupled to an output of the progressive MPEG-2 decoder;
- d) a video processing module having an input coupled to an output of the buffer;
- and
- e) a progressive display having an input coupled to an output of the video processing module.
A video system for producing a corrected progressive MPEG-2 output from an MPEG-2 compressed video source comprising:
- a) an MPEG-2 compressed video source;
- b) a interlaced MPEG-2 decoder having an input coupled to an output of the MPEG-2 compressed video source;
- c) a deinterlacer having an input coupled to an output of the interlaced MPEG-2 decoder;
- d) a buffer having an input coupled to an output of the deinterlacer;
- e) a video processing module having an input coupled to an output of the buffer;
- and
- f) a progressive display having an input coupled to an output of the video processing module.
A video system for producing a corrected progressive MPEG-2 output from an MPEG-2 compressed video source comprising:
- a) an MPEG-2 compressed video source;
- b) a interlaced MPEG-2 decoder having an input coupled to an output of the MPEG-2 compressed video source;
- c) a buffer having an input coupled to an output of the interlaced MPEG-2 decoder;
- d) a deinterlacer/video processing module having an input coupled to an output of the buffer;
- and
- e) a progressive display having an input coupled to an output of the video processing module.
