摘要： 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.

摘要： 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. Therefore, it is possible to prevent error propagation by limiting the transmission error within a smallest possible length and to reduce a decoding time by using a parallel processing.

摘要： A decoding method of detecting a transmission error region and recovering correctly decoded data and a decoding apparatus using the same. The decoding method includes comparing encoding status information with decoding status information by receiving encoded data and the encoding status information of at least one synchronization point set in every predetermined period to detect a transmission error and to obtain the decoding status information of a corresponding synchronization point while decoding the encoded data, and continuing to decode the received data if the encoding status information of the at least one synchronization point is the same as the decoding status information of the corresponding synchronization point, and recovering previously decoded data before a previous synchronization point by detecting a transmission error region between the corresponding synchronization point and the previous synchronization point if the encoding status information is different from the decoding status information. It is possible to detect an error for each synchronization point and recover data positioned in a region having no error.

摘要： 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. Also, a condition that a DTS delta value should always be a positive number is met.
