20130076770 | METHOD AND APPARATUS FOR ACCESSING DATA OF MULTI-TILE ENCODED PICTURE STORED IN BUFFERING APPARATUS - A method for read pointer maintenance of a buffering apparatus, which is arranged to buffer data of a multi-tile encoded picture having a plurality of tiles included therein, includes the following steps: judging if decoding of a first tile of the multi-tile encoded picture encounters a tile boundary of the first tile; and when it is judged that the tile boundary of the first tile is encountered, storing a currently used read pointer into a pointer buffer, and loading a selected read pointer from the pointer buffer to act as the currently used read pointer. | 03-28-2013 |
20140053254 | GRAPHICAL AUTHENTICATION SYSTEM AND METHOD FOR ANTI-SHOULDER SURFING ATTACK - The present disclosure relates to a graphical authentication system and the method of the same for anti-shoulder surfing attack, With the system and method, the user is able to select a graph form a graph list, The selected graph is partitioned into M*N pieces of graph blocks, Further, one of the graph blocks is selected to generate a password, when login, the system and method create randomly a login hint to indicate a position, the user therefore scroll a set of horizontal bar and vertical bar to the position according to the login hint and confirm entry, the system and method further proceed a authentication process to verify the entry to determine the validity of the authentication. | 02-20-2014 |
20140133580 | VIDEO DECODING METHOD AND SYSTEM THEREOF - A video decoding method for decoding a bit stream to a plurality of frames, applied in a video decoding system, includes: determining whether a size of a current picture is equal to that of a next picture according to the bit stream; scaling a corresponding reference frame for the next picture to generate a scaled frame when the size of the current picture is not equal to that of the next picture; and storing the scaled frame in a first buffer of a storage unit, wherein at least a portion of a first frame originally stored in the first buffer is used; wherein when it is determined that the size of the current picture is not equal to that of the next picture, the next picture is encoded in the bit stream in a mode that the scaled corresponding reference frame is required for decoding the next picture. | 05-15-2014 |
20140192899 | METHOD AND APPARATUS FOR REFERRING TO BITSTREAM ADDRESS RELATED INFORMATION DERIVED FROM SEGMENT OF MULTI-TILE PICTURE TO DETERMINE BITSTREAM START ADDRESS OF TILE OF MULTI-TILE PICTURE - A tile processing method includes at least the following steps: parsing a bitstream of at least a multi-tile picture for deriving bitstream address related information from a segment header of at least a specific segment of the multi-tile picture; and utilizing a tile processing circuit for receiving at least the bitstream address related information and referring to at least the received bitstream address related information to determine a bitstream start address of a specific tile of the multi-tile picture. | 07-10-2014 |

20150334387 | COUNT TABLE MAINTENANCE APPARATUS FOR MAINTAINING COUNT TABLE DURING PROCESSING OF FRAME AND RELATED COUNT TABLE MAINTENANCE METHOD - A count table maintenance apparatus for maintaining a count table referenced to apply a backward adaptation to a probability table. The count table maintenance apparatus includes a count data access interface, at least one buffer, and at least one count data updating circuit. The count data access interface determines a read address and a write address of the storage apparatus. The at least one buffer buffers at least one input count data, wherein the at least one input count data is derived from count data read from the count table according to the read address. The at least one count data updating circuit updates the at least one input count data read from the at least one buffer to generate at least one updated count data, and store the at least one updated count data into the storage apparatus according to the write address. | 11-19-2015 |
20150350566 | VIDEO PROCESSING APPARATUS WITH TRANSFORM UNIT SIZE SELECTION, MODE INFORMATION UNIT SIZE SELECTION AND/OR PICTURE WIDTH/HEIGHT DECISION, AND RELATED VIDEO PROCESSING METHOD THEREOF - One exemplary video processing apparatus includes a control circuit and a size selection circuit. The control circuit determines picture boundary information. The size selection circuit refers to at least the picture boundary information to select a size for a block associated with encoding of a picture, wherein selection of the size is constrained by the picture boundary information to ensure that the block with the selected size is not across a picture boundary of the picture. | 12-03-2015 |
20150350673 | VIDEO PROCESSING APPARATUS FOR STORING PARTIAL RECONSTRUCTED PIXEL DATA IN STORAGE DEVICE FOR USE IN INTRA PREDICTION AND RELATED VIDEO PROCESSING METHOD - A video processing apparatus includes a reconstruct circuit, a storage device, and an intra prediction circuit. The reconstruct circuit generates reconstructed pixels of a first block of a picture. The storage device at least stores a portion of the reconstructed pixels of the first block, wherein a capacity of the storage device is smaller than a reconstructed data size of the picture. The intra prediction circuit performs intra prediction of a second block of the picture based at least partly on pixel data obtained from the storage device. | 12-03-2015 |
