    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: 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.
