20100121974	STEPWISE PROBING FOR ADAPTIVE STREAMING IN A PACKET COMMUNICATION NETWORK - A packet data communication network is probed with stuffed data inside the ordinary media streams to determine whether the network is capable of handling a higher bitrate before performing adaptive streaming to switch from a lower bitrate to a higher bitrate in order to avoid having to transmit actual streaming data from a lower bitrate to a higher bitrate first, determining that the network cannot handle the higher bitrate, and causing the server to switch back to the lower bitrate while providing varying video quality to the user.	05-13-2010

20090028428	Media Content Management - The invention relates to media management and combats media degradations arising when transcoding the media. The invention solves this by—generating processing hints based on the media transcoding. The hints are employed for controlling a post-transcoding processing of the transcoded media content in connection with rendering the media. The hints and this controlled processing increases the user-perceived quality when rendering the media by mitigating the media degradations caused by the transcoding. The processing hints could specify how the actual transcoding was performed by including values of the employed transcoding parameters or information of the alterations to the media caused by transcoding. Furthermore, instructions or commands for appropriate post-transcoding processing could also be processing hints according to the invention.	01-29-2009

20080253690	Resizing Video and Aligning Video Image Edges to Block Boundaries and Picture Boundaries - The invention teaches a method of positioning a first image having a first image format into a second image comprising multiple image blocks and having a second image format. A straight boundary of at least one image block in the second image is identified. The first image is positioned into the second image by aligning an edge of the first image with the identified straight boundary. Alternatively, a block row or column of the first image can be aligned with the straight boundary but then in such a way that an edge of the first image parallel to the block row or column is aligned with a boundary of a row or column of image blocks in the second image. This image positioning reduces any bleeding artifacts and the number of bits required for representing the image during encoding.	10-16-2008
