Provided is a method and apparatus for generating and consuming sensory effect media. The method for generating sensory effect media includes receiving sensory effect information about sensory effects that are applied to media, and generating sensory effect metadata including the received sensory effect information. The sensory effect metadata includes effect description information for describing the sensory effects and device control description information for controlling devices that perform the sensory effects.

An apparatus and method for transmitting MPEG-4 data synchronized to MPEG-2 data is disclosed. The apparatus for transmitting MPEG-4 data synchronized to MPEG-2 data includes: an object separation unit for extracting MPEG-4 object data from MP4 data, separating meta information from the object data, and generating program information and synchronization information; a conversion unit for converting the MPEG-4 object data to MPEG-4 packets of which data structure is the same as that of MPEG-2 data, based on the program information and synchronization information; and a multiplexing unit for multiplexing the MPEG-4 packets with the MPEG-2 data.

A video summary description system for describing video summary by meta data to provide overview functionality that makes it feasible to understand the overall contents of the original video within a short time with navigation and browsing functionalities, and that makes it feasible to search the desired video contents efficiently. The system includes a HierarchicalSummary Description Scheme (DS) for describing a video summary that includes a HighlightLevel DS having at least one HighlightSegment DS. The HighlightSegment DS describes information on a highlight segment corresponding to one of the video summary intervals, and the HighlightSegment DS includes a VideoSegmentLocator DS for describing time information or the video itself of the highlight segment and an ImageLocator DS describing a representative frame of the highlight segment.

A texture description method in frequency domains and a texture-based retrieval method using the same, in which image signals are converted into those in a frequency domain of a Polar coordinate system. The texture description method in the frequency domain includes a first step of generating a frequency layout by partitioning the frequency domain into a set of feature channels; a second step of extracting the texture feature values of the image from the respective feature channels; and a third step of constituting a texture descriptor of the image in a vector form using the texture feature values extracted from the respective feature channels of the frequency layout. In a texture-based retrieval described in the frequency domain, a retrieval method capable of satisfying respective or all the retrieval conditions such as scale-, rotation- and intensity-invariant retrieval of relevant texture images is provided. Also, a retrieval method of computing the rough scheme of texture to provide a browsing functionality in retrieving is provided.
