| 20120082236 | OPTIMIZED DEBLOCKING FILTERS - An encoder executes an iterative search method for selecting deblocking parameters for coded video. According to the method, a decoded picture may be deblocked according to parameters associated with a multi-dimensional deblocking vector and an error, called the “deblocking error” may be estimated therefrom. If the estimated error exceeds a predetermined threshold, then alternate deblocking vectors may be created, each advanced from the current deblocking vector in a respective dimension. The method may deblock the decoded picture according to each advanced vector and may estimate errors from each of the deblocking of each advanced vector. Finally, the deblocking vector may be revised for a next iteration according to a gradient derived from the estimated deblocking errors of the vector dimensions. This gradient-based search method may converge on a final set of deblocking parameters in an efficient manner. | 2012-04-05 |
| 20120082237 | Automatic Temporal Layer Bit Allocation - Disclosed herein are techniques and computer readable media containing instructions arranged to determine a bit allocation for a temporal base layer and at least one temporal enhancement layer. The techniques are enhanced to yield improved reproduced quality for the case where both a temporal base layer and at least one temporal enhancement layer is being used. An exemplary method for determining a bit allocation to one base layer includes initializing a bit allocation between the base layer and the at least one enhancement layer, determining a quality difference between the base layer and the at least one enhancement layer, expressed, for example, in the Quantizer Parameter of the last picture of each layer within a GOP, and determining a new bit allocation between the base layer and the at least one enhancement layer based on the quality difference and at least one constant factor. | 2012-04-05 |
| 20120082238 | CODING AND DECODING UTILIZING PICTURE BOUNDARY VARIABILITY IN FLEXIBLE PARTITIONING - There is a coding including-preparing coding units based on source pictures. The coding units are associated with largest coding tree units (LCTUs) which are polygons of source pictures. A tree format is utilized in processing the LCTUs into coding units. The preparing includes calculating an efficiency measure associated with a source picture position in a coordinate system based on fitting the coordinate system and the source picture with respect to each other. The preparing includes determining the source picture position based on a coding efficiency goal. The source picture is divided into LCTUs based on the coordinate system and the determined source picture position. There is also a decoding including processing video compression data which is generated based on the coding units based on partitions of LCTUs. | 2012-04-05 |
| 20120082239 | METHOD OF PROCESSING TRAFFIC INFORMATION AND DIGITAL BROADCAST SYSTEM - A digital broadcast transmitting/receiving system and a method for processing data are disclosed. The method for processing data may enhance the receiving performance of the receiving system by performing additional coding and multiplexing processes on the traffic information data and transmitting the processed data. Thus, robustness is provided to the traffic information data, thereby enabling the data to respond strongly against the channel environment which is always under constant and vast change. | 2012-04-05 |

| 20120082241 | Method and Apparatus of Adaptive Loop Filtering - A method and apparatus for processing in-loop reconstructed video using an in-loop filter is disclosed. In the recent HEVC development, adaptive loop filtering (ALF) is being adopted to process in-loop reconstruction video data, where ALF can be selectively turned ON or OFF for each block in a frame or a slice. An advanced ALF is disclosed later that allows a choice of multiple filter sets that can be applied to the reconstructed video data adaptively. In the present disclosure, pixels of the in-loop reconstructed video data are divided into a plurality of to-be-filtered regions, and an in-loop filter from a filter set is determined for each to-be-filtered region based on a rate-distortion optimization procedure. According to one embodiment of the present invention, computation of cost function associated with the rate-distortion optimization procedure is related to correlation values associated with original video data and the in-loop reconstructed video data. Furthermore, the correlation values can be shared by the multiple candidate filters during the rate-distortion optimization procedure for said each to-be-filtered region. In another embodiment, the correlation values can be shared by multiple candidate to-be-filtered regions of an area of the in-loop reconstructed video data during the rate-distortion optimization procedure for the area of the in-loop reconstructed video data. | 2012-04-05 |
