Abstract
MPEG-7 is a standard to provide a standardized way of describing contents of multimedia information. The development of technologies related to the MPEG-7 and exploiting MPEG-7 applications have been a main research interest of us for the last two years. TV broadcasting is one specific area of interest among various applications to which MPEG-7 can be of benefit. The VideoGadgetTM, which is an indexing and retrieval engine of multimedia data, is designed to aid user friendly environment of Digital TV as well as conventional analogue TV. By enabling automatic feature extraction and indexing of received TV program with help of low-cost random access storage device, a dull and conventional TV can turn into an interactive personalized entertainment center. With various user-friendly functionalities such as non-linear browsing of received programs, structure-based navigation, and searching/filtering of programs, the user can view the received program anytime the user prefers in the way the user prefers. Even though the Video-GadgetTM project, which is currently in progress, aims an environment of the Digital TV broadcast with MPEG-7 descriptions, a version of the Video-GadgetTM is under development to actually generate MPEG-7-like descriptions while the analogue stream is received. The real-time generation of the content description in detail brings many problems to solve such as limited I/O bandwidth and computing power and extensive sharing of the system resources. Due to the limited resource, some features are impossible to be extract in the real time, the functionality using those features should be redesigned to use simpler features. Once the Digital TV broadcast with MPEG-7 descriptions become available, the feature extraction part of the Video-GadgetTM will be employed by the MPEG7 description generation server or the service provider and only the retrieval engine including search, browsing, and filtering functionality will remain in the client part.
