Broadcasting environment of present our country is greeting period of transition that undergo a change to digital broadcasting system in analog broadcasting system continued for last several decades. With change of these broadcasting environment interest about various digital broadcasting contents industry that fill to digital broadcasting infra and unlawfulness reproduction prevention technology far digital broadcasting contents of high added value is rising. According as is converted to digital broadcasting environment interest about reproduction prevention is well-founded to be risen sensitively. First analog broadcasting environment can not remove perfectly error at transmission in receiver, but can reconstruct contents such as original by error correction function in receiver in the case of digital broadcasting environment. Secondarily, although quality of copy is dwindled than original repeat reproduction in case of analog, many copies are available innumerably regardless of number of times of copy keeping quality such as original in the case of digital And third element is possible easily to anyone to on-line along with development of internet in case of digital contents unlike analog.

The advertisement market is an industry that is heavily influenced by media changes. As the digital broadcasting has settled, TV, a typical advertisement medium, has evolved from a passive content consuming medium into a platform for operating various data services as well as broadcasting programs. These changes mean that viewers are able to actively consume TV contents including advertisement, so the broadcasting industry needs to consider about the growth strategies that link the advertisement market with data services. This study designed a digital broadcasting data service that provides supplementary information of ID advertisement with short exposure time (less than 10 seconds) and insufficient space (less than 1/4 of TV screen). Specifically, we designed the user scenario and user interface of the data service, defined representative types of ID advertisement and the supplementary information for each type, developed a method, based on the international digital broadcasting standard DVB, for providing the supplementary information to the data service.

Recently, research started to focus on Digital Multimedia Broadcasting(DMB), while the DMB service is already being launched to provide high quality audio, video and data broadcasting in Korea. Therefore, the demand for multimedia contents is also rose very sharply. In this paper, we introduced an MPEG-4 contents authoring system with mobile device for Digital Multimedia Broadcasting. Our system allows both single-handed and collaborative authoring modo. Further more, to overcome the delaytime for decoding the BIFS information, we also introduced an efficient algorithm to generate dynamic and light BIFS information.
