20090034621	Low-Complexity Motion Vector Prediction Systems and Methods - A method of motion vector prediction for use in differential motion vector coding within a block motion-compensation-based video coder. The video coder employs a generalized multiple reference picture buffer which may contain multiple reference pictures in both the forward and backward temporal direction from the current picture. For the purpose of coding selections of reference pictures within the buffer, the pictures are organized into two, potentially overlapping, lists of reference pictures. The prediction of a motion vector that selects a reference picture using a given reference picture list is not dependent upon any motion vectors that select their reference pictures using the other reference picture list. The values of spatially neighbouring motion vectors that use the same list of reference pictures as the motion vector being predicted are used for prediction, regardless of the relative temporal direction of the current and neighbouring motion vectors.	02-05-2009

20120117225	METHODS AND APPARATUS FOR PROVIDING A MEDIA STREAM QUALITY SIGNAL - Systems, methods and apparatus are provided for computing quality scores for a media session delivered using an adaptive streaming protocol, where the quality score may be an estimate of a mean opinion score. The quality score reflects the impact of network delivery on a viewer's quality of experience (QoE). In particular, the quality score is generally based on the effects of stream switch events, as stream switches may be the result of impaired network delivery. Other network events, such as re-buffering events may also be incorporated in the score.	05-10-2012

20110122940	METHOD AND APPARATUS FOR VC-1 TO MPEG-2 VIDEO TRANSCODING - A method for transcoding from a VC-1 format to an MPEG-2 format is disclosed. The method generally comprises the steps of (A) decoding an input video stream in the VC-1 format to generate a picture; (B) determining a first mode indicator for the picture; and (C) coding the picture into an output video stream in the MPEG-2 format using one of (i) an MPEG-2 field mode coding and (ii) an MPEG-2 frame mode coding as determined from the first mode indicator.	05-26-2011
20110135004	H.264 TO VC-1 AND VC-1 TO H.264 TRANSCODING - A method for transcoding from an H.264 format to a VC-1 format. The method generally comprises the steps of (A) decoding an input video stream in the H.264 format to generate a picture having a plurality of macroblock pairs that used an H.264 macroblock adaptive field/frame coding; (B) determining a mode indicator for each of the macroblock pairs; and (C) coding the macroblock pairs into an output video stream in the VC-1 format using one of (i) a VC-1 field motion compensation mode coding and (ii) a VC-1 frame motion compensation mode coding as determined from the mode indicator.	06-09-2011
20120002727	METHOD AND APPARATUS FOR MPEG-2 TO VC-1 VIDEO TRANSCODING - A method for transcoding from an MPEG-2 format to a VC-1 format is disclosed. The method generally comprises the steps of (A) decoding an input video stream in the MPEG-2 format to generate a picture; (B) determining a mode indicator for the picture; and (C) coding the picture into an output video stream in the VC-1 format using one of (i) a VC-1 field mode coding and (ii) a VC-1 frame mode coding as determined from the mode indicator.	01-05-2012
20120110167	DEVICE WITH VIDEO BUFFER MODELING AND METHODS FOR USE THEREWITH - A device includes a frame data analyzer that generates buffer increment data based on frame data sent from the media server to the media client and further based on acknowledgement data sent from the media client to the media server. A playback data generator generates playback data based on frame data buffer contents and further based on player state data. A frame buffer model generator generates a buffer fullness indicator and the frame data buffer contents, based on the buffer increment data and the playback data. A player state generator generates the player state data, based on the buffer fullness indicator and further based on media client data, media server data and player command data.	05-03-2012
