| 20140119443 | IMAGE DECODING APPARATUS - A method for encoding an intra prediction mode according to the present invention selects an intra prediction mode for a current block, determines the number of valid MPM candidates by checking the validity of MPM candidates of the current block, and if the number of valid MPM candidates is less than a previously set number, adds additional intra prediction modes as MPM candidates. MPM candidates can be adaptively added on the basis of the directionality of valid MPM candidates. Additionally, during the encoding of residual intra prediction modes, residual intra prediction modes are realigned on the basis of the directionality of valid MPM candidates. Accordingly, the present invention allows the information for encoding the intra prediction mode of the current block to be minimized by adding MPM candidates or realigning the residual intra prediction modes on the basis of the directionality of valid MPM candidates. | 2014-05-01 |
| 20140119444 | Intra Frame Predication Scanning Method for Video Coding and Video Coding Method - An intra frame predication scanning method for video coding includes steps of: providing a two-dimensional residual coefficient array of a pixel block; dividing the two-dimensional residual coefficient array into a plurality of sub-arrays; converting, in a predetermined order, residual coefficients in the respective sub-array into a one-dimensional individual-sub-array residual coefficient series; connecting the one-dimensional individual-sub-array residual coefficient series of all the sub-arrays as a one-dimensional all-sub-array residual coefficient series of the pixel block; and performing an entropy coding on the one-dimensional all-sub-array residual coefficient series. A video coding method is also provided. | 2014-05-01 |
| 20140119445 | METHOD OF CONCEALING PICTURE HEADER ERRORS IN DIGITAL VIDEO DECODING - A method of concealing errors in picture header information within H.263-encoded video compares current group-of-block frame identification (GFID) information to GFID information from the previous frame. If the GFID values are equal, the picture header information from the previous frame is used to decode the current frame. Otherwise, a selected parameter in the previous picture header information (for example, “picture type”) is altered and decoding proceeds with the altered picture header information. Preferably, only a portion of the current frame is initially decoded and validated prior to decoding the remainder of the frame. If the decoded portion is error-free, the decoding continues with the selected picture header information. If errors are found in the decoded portion, the picture header information is modified and the decoding process continues accordingly. | 2014-05-01 |
| 20140119446 | PRESERVING ROUNDING ERRORS IN VIDEO CODING - An input receives a video signal comprising a plurality of frames of a video image, each frame comprising a plurality of higher resolution samples. A projection generator generates a different respective projection of each of a sequence of the frames, each projection comprising a plurality of lower resolution samples, wherein the lower resolution samples of the different projections represent different but overlapping groups of the higher resolution samples which overlap spatially in a plane of the video image. Inter frame prediction coding is performed between the projections of different ones of the frames based on a motion vector for each prediction. The motion vector is scaled down from a higher resolution scale corresponding to the higher resolution samples to a lower resolution scale corresponding to the lower resolution samples. An indication of a rounding error resulting from this scaling is determined and signalled to the receiving terminal. | 2014-05-01 |
| 20140119447 | REFERENCE PICTURE STATUS FOR VIDEO CODING - The techniques of this disclosure may be generally related to reference statues of pictures. The techniques may store the reference status information of reference pictures of a picture, at an instance when the picture is being coded. The techniques may then utilize the reference status information of the reference pictures of the picture, at the instance when the picture was coded, to inter-predict video blocks of a subsequent picture. | 2014-05-01 |
| 20140119448 | MOVING IMAGE ENCODING APPARATUS, IMAGE CAPTURING APPARATUS, AND METHOD OF CONTROLLING MOVING IMAGE ENCODING APPARATUS - A moving image encoding apparatus that supports a plurality of image formats is provided. A format conversion unit converts a format of moving image data. A determination unit determines a prediction mode of intra-frame prediction encoding based on the converted moving image data. An encoding unit performs intra-frame prediction encoding on the moving image data acquired from a memory unit using the determined prediction mode. The determination unit supports moving image data in a predetermined format having a predetermined ratio of the luminance component and the color difference components. The format conversion unit, when the format of the moving image data acquired from the memory unit differs from the predetermined format, converts the format of the moving image data acquired from the memory unit into the predetermined format. | 2014-05-01 |
