Spatially Constrained Motion Estimation, E.g., At Image Or Region Borders (epo) Patents (Class 375/E7.116)
  • Patent number: 9532088
    Abstract: A method of generating a trick-play stream is provided that includes providing a master trick-play stream having a plurality of groups of pictures, wherein each group of pictures comprises a leading intra-coded frame and a plurality of inter-coded frames, and frames within of each group of pictures encoded with a temporally scalable hierarchical encoding relationship, deriving a trick-play stream from the master trick-play stream for a particular temporal resolution by skipping a consistent pattern of frames from each group of pictures that are not needed to decode other frames at the particular temporal resolution according to the temporally scalable hierarchical encoding relationship, and providing the trick-play stream to a client device, wherein the trick-play stream is packaged to appear to the client device as a standards-compliant adaptive bitrate stream.
