Abstract: Managing a decoded picture buffer (DPB) in a multi-view video coding (MVC) decoder is provided by detecting a trailing picture after an anchor picture in a base view, marking one or more reference pictures prior to the anchor picture as unused for reference in base view and one or more non-base views, transmitting the one or more marked reference pictures to an electronic device for post-processing, determining that the one or more reference pictures are displayed, and releasing the one or more pictures from the DPB in the base view and the one or more non-base views, once the one or more pictures are displayed and if those pictures are marked as unused for reference.

Abstract: A decoding method, medium, and apparatus capable of preventing error propagation and implementing parallel processing. A decoding method includes comparing encoding information with decoding information at synchronization points for detecting a transmission error, and continuing to decode the encoded data if both the encoding and decoding information match, or continuing to decode remaining data located beyond the corresponding synchronization point by limiting a transmission error region to between the corresponding synchronization point and an immediately previous synchronization point, with reference to the encoding information if the encoding and decoding information do not match. Furthermore, the encoded data of a plurality of regions are simultaneously decoded in parallel, with reference to the encoding information of a plurality of synchronization points.

Abstract: An apparatus and method to generate and restore an RTP (Real-Time Transmission Protocol) packet. A setting unit assigns a CTS (Composition TimeStamp), a DTS (Decoding TimeStamp), and a PSN (Packet Sequence Number) that sequentially increase according to a packet generation order for each of a plurality of SL (Synchronization Layer) packets, extracting a time stamp length and a packet sequence number length from an SLCD (SL Configuration Descriptor) within each SL packet. A packet generating unit generates a header of the SL packet accommodated in an RTP packet header and the RTP packet based on the CTS, the DTS, the PSN, the time stamp length and the packet sequence number length. Since only difference values in the CTS, the DTS, and the PSN information between a previous SL packet and the present SL packet, are recorded, a number of bits can be reduced if the CTS value rolls over and a multiple SL packet can be made for the SL packet having a time stamp length greater than 32 bits.

Abstract: An apparatus and method for entropy encoding and decoding of video data. The method for entropy encoding video data includes dividing the video data into at least one partial video data portion and determining an entropy encoding mode to be used for each of the partial video data portion between at least two different entropy encoding modes and performing entropy encoding on each of the partial video data portions using the determined entropy encoding mode.

Abstract: There are provided a method of context adaptive binary arithmetic coding (CABAC) and an apparatus of the same. The CABAC method includes generating a plurality of syntax elements respectively corresponding to a plurality of predetermined sized residual blocks included in an input block; grouping flags of each of the residual blocks which indicate whether a non-zero transform coefficient exists among the syntax elements; and context adaptive binary arithmetic coding the grouped flags. The complexity of context adaptive binary arithmetic coding is reduced, thereby performing context adaptive binary arithmetic coding more quickly and easily.
