摘要： Provided is a scalable video coding method and apparatus. Motion data of a high-quality fine grain scalability (FGS) layer is used for interlayer coding in order to remove redundancy between coarse grain scalability (CGS) layers or layers having different spatial resolutions, and information indicating that data of the FGS layer has been used for interlayer motion prediction is inserted for Moving Picture Expert Group (MPEG)-4 scalable video encoding. A bitstream extractor checks the information and performs extraction to maintain the data of the FGS layer. MPEG-4 scalable video decoding is performed using the information. By using the FGS layer, interlayer redundancy can be efficiently removed, thereby improving encoding efficiency.

摘要： The present invention relates to a method of systematically and synthetically accessing modality conversion that is an important part in the contents adaptive conversion process of a universal multimedia access system. The present invention provides an effective method of solving a problem, which is incurred at the time of modality conversion and still remains as one of difficult problems incurred during adaptive contents conversion. For this purpose, the present invention includes overlapped contents modeling newly proposed to determine modality conversion, a method of flexibly and clearly expressing and applying user preference for the modality conversion, and a resource allocation method of distributing resources among complicated contents based on the user preference. As a result, the integration of the above three methods provides a synthetic solution, particularly, to a problem incurred in the modality conversion and, generally, to a problem incurred in the adaptive conversion of contents.

摘要： Disclosed are a method and a system that could adaptively improve the visual quality of people with low-vision impairment, regardless of network and terminal. The low-vision impairment is described by a set of "symptoms" that is semantically defined. As the description tool of low vision impairments, it is flexible and reliable to use the proposed "symptoms" based descriptions rather than individually identified names of eye disease, because the user can describe his/her low-vision impairment by specifying associated symptoms based on his/her own experience. The inputted visual contents are adaptively transformed according to the low vision-impairment.

摘要： Provided are a method and apparatus for displaying lightweight applications scene representation (LASeR) content. A LASeR markup language (ML) that is based on a LASeR binary stream or a LASeR extensible markup language (XML) is parsed so as to generate a LASeR document object model (DOM). A LASeR application program interface (API) is used to generate a LASeR DOM object tree. A LASeR player accesses the LASeR DOM to display LASeR DOM scene information.
