Abstract:
Disclosed are a signaling method for a stereoscopic video service and an apparatus using the method. An image decoding method comprises: a step of determining a field value based on a broadcast service type and a display mode in decoding a program level descriptor; and a step of determining an encoded stream type, whether an elementary stream is a reference stream, whether the elementary stream is a left-eye image or a right-eye image, additional image upsampling information and information on a subsampled line. Thus, efficiency of encoding/decoding an additional image for a stereoscopic video content may increase.
Abstract:
Disclosed are an implementation method of a user interface and a device using the same method. The implementation method of a user interface comprises a step for receiving AUI(Advanced User Interaction) pattern information and a step for interpreting the inputted AUI pattern information based on a predefined interface. Therefore, a preset AUI pattern generated in a user interaction device is implemented in various applications by defining the implementation method of an interface between a user interaction device and a scene description.
Abstract:
The invention relates to an advanced user interaction (AUI) interface method, comprising a step of determining, from between a basic pattern type and a synthetic pattern type, the pattern type corresponding to physical information inputted from an object. The synthetic pattern type is a combination of at least two basic pattern types. The basic pattern type includes a geometric pattern type, a symbolic pattern type, a touch pattern type, a hand posture pattern type, and/or a hand gesture pattern type. The synthetic pattern type may include attribute information indicating whether the synthetic pattern type is one created by the same object. Thus, an advanced user interaction interface for advanced user interaction devices such as a multi-touch device and a motion-sensing remote controller may be provided.

A computational graceful degradation method is disclosed using priority information in multiple objects case. The method degrades the amount of computation in different ratio every object using the priority information if computational power of a decoder does not come up to that necessary for processing encoded multimedia data as decoding the multimedia data encoded by several objects unit, the priority information being determined by an encoder for optimal graceful degradation in terms of relatively importance between respective objects.
