摘要: The construction method of NALU (Network Abstraction Layer Unit) for IPv6 label switching and its using algorithms of video encoding, QoS control, and decoding are provided. According to an embodiment of the present invention, the NALU format is composed of the NALH (Network Abstraction Layer Header) including the label and the NAL (Network Ab¬straction Layer) payload. Here, the label is determined based on layer information which is combination of a spatial scalable level, a temporal scalable level, and a quality scalable level of the encoded data. The decoder uses the label to decide which one of multiple decoding modules is used to decode the current NAL payload. Moreover, the label can be included in the packet header so that the MANE (Media Aware Network Element) can use the label to decide whether to forward the packet or drop it. For example, the label in the packet header can be used for QoS control of video service by using the flow label field in IPv6 packet header. The IPv6 router can identify priority of the video packet by using the 20 bit long flow label, into which the label in NALH can be inserted. According to the embodiment, the MANE assumed in the MPEG and JVT (Joint Video Team) can be implemented effectively.

摘要: Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

摘要: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

摘要: The present invention relates to a method and device for sharing a candidate list. A method of generating a merging candidate list for a predictive block may include: producing, on the basis of a coding block including a predictive block on which a parallel merging process is performed, at least one of a spatial merging candidate and a temporal merging candidate of the predictive block; and generating a single merging candidate list for the coding block on the basis of the produced merging candidate. Thus, it is possible to increase processing speeds for coding and decoding by performing inter-picture prediction in parallel on a plurality of predictive blocks.

For example, the label in the packet header can be used for QoS control of video service by using the flow label field in IPv6 packet header.
