摘要:
Provided is a Simple Aggregation Format (SAF) synchronization packet structure including a SAF synchronization packet header and a SAF synchronization packet payload and multiplexing diverse element streams which include a scene description elementary stream. The SAF synchronization packet header includes time information related to an access unit included in the SAF synchronization packet payload, and the SAF synchronization packet payload includes header information on the access unit and payload information indicating the access unit. Since the present invention can multiplex diverse elementary streams effectively and simply into one data stream, synchronized data transmission is possible. Since the present invention accommodates a synchronization layer packet of the MPEG-4 system, it can be easily integrated with the MPEG-4 system and utilize the advantage of the MPEG-4 synchronization layer packet such as the concept of an access unit or a degradation priority.

摘要:
A method and apparatus for transferring user information between different terminals are disclosed. The method includes saving by a first terminal, when a change is made to user information during playback of content, the changed user information in a scene history, performing a terminal change from the first terminal to a second terminal, and resuming, by the second terminal, playback of the content from a continued scene after the last scene played back by the first terminal. Consequently, in a terminal change, the user may use the second terminal to play back the same content from the continued scene using the same content usage environment as the first terminal.

Provided are intelligent water ring scan apparatus and method thereof, image encoding/decoding apparatus using the water ring scanning and method thereof, and a computer-readable recording medium for recording a program that implements the methods. The apparatus or method of this research selectively improves the image quality of a particular image part that needs to be encoded with priority by transmitting the image data of the particular image part suitably for a human visual system so as to provide a visually improved image. The encoding apparatus of this research differentiates the amount of image data depending on the significance of a certain image part to process the image in various qualities suitably for the human visual system. The methods of this research can be applied to an image encoding/decoding process.

摘要:
Provided is a method for transmitting a stereoscopic video in a digital broadcasting system, the stereoscopic video being composed of a left view and a right view. The method includes: generating information indicating that the video is stereoscopic, information about a composition type of the stereoscopic video, and additional information based on the composition type; and transmitting the stereoscopic video and the generated information. The composition type is to compose the stereoscopic video of a single or two encoding streams by using the left view and the right view. In the case of a single stream mode in which the stereoscopic video is composed of the single encoding stream, the additional information includes information about positions of the left and right views. In the case of a dual stream mode in which the stereoscopic video is composed of the two encoding streams, the additional information includes information indicating whether the respective encoding streams are the left view or the right view and information indicating correlation between the respective encoding streams.
