20120236929 | CONTEXT ADAPTATION WITHIN VIDEO CODING MODULES - Context adaptive video coding is described in which encoding and decoding relies on deriving context adaptive coding tools, which can be applied within a coder (encoder and/or decoder) to one or more coding processes. A discontinuity of the block is identified, and a context feature extracted having directionality and location of discontinuity. Coding then uses the context adaptive tools to enhance coding efficiency, without the need of additional side information. Context adaptation according to invention can be applied such as to inter prediction, intra prediction, transform, interpolation filtering, and/or scanning. | 2012-09-20 |
20120236930 | MPEG-W DECODER - A device comprising a Moving Picture Experts Group (MPEG)-W decoder; and one or more processing systems to execute the instructions of the MPEG-W decoder, which configure the one or more processing systems to receive a request for streaming content; select an estimate of a bandwidth for a connection between a destination device and a source device; select a device type pertaining to the destination device; generate a stream request that includes an MPEG-W link, the estimate of the bandwidth, the device type, the MPEG-W link including an address pertaining to the source device, a name of the streaming content, and a file extension of an MPEG-W format; transmit the stream request to the source device; select a streaming content based on the stream request; wherein the streaming content has a resolution corresponding to the estimate of the bandwidth; and transmitting the streaming content to the destination device. | 2012-09-20 |
20120236931 | TRANSFORM COEFFICIENT SCAN - This disclosure describes techniques for coding transform coefficients for a block of video data. According to these techniques, a video encoder may adaptively scan a first plurality of coefficients of a two-dimensional matrix of coefficients, and use a fixed scan technique for a second plurality of coefficients of the two-dimensional matrix, to generate a one-dimensional vector of transform coefficients. Also according to these techniques, a video decoder may adaptively scan a first plurality of coefficients of a one-dimensional vector of coefficients, and use a fixed scan technique for a second plurality of coefficients of the one-dimensional vector, to generate a two-dimensional matrix of transform coefficients. | 2012-09-20 |
