25. A system as defined in claim 25, wherein the content analysis block segments by determining the content signature such that motion level information of the video content is determined.
-
26. A system as defined in claim 26, wherein the motion level information comprises motion vectors that indicates motion for a pixel block of a frame with respect to a reference frame of the digital video content such that a motion vector of greater than a threshold magnitude is assessed to be a high motion frame comprising a temporal ROI.
- 27. A system as defined in claim 27, wherein a frame that is assessed to be a temporal ROI is encoded at a higher bitrate than a frame that is not assessed to be a temporal ROI.
- 31. A system as defined in claim 31, wherein the analysis trial comprises an encoding in which frames of the video content are processed such that a frame region that has increased complexity is identified as comprising a spatial ROI.
-
41. A method of processing digital video content for delivery over a communications channel, the method comprising:
-
performing an analysis trial that determines content signature of the digital video content such that the analysis trial comprises an encoding in which frames of the video content are processed such that a frame region that has increased complexity is identified as comprising a spatial ROI and motion estimation processing for frames of the digital video content such that frames of the digital video content with motion vectors greater than a threshold value are identified as comprising a temporal ROI; segmenting the digital video content into one or more regions of interest (ROI) in accordance with the content signature of the digital video content; encoding the digital video content in accordance with the ROI segmentation and the communications channel. - View Dependent Claims (43)
