It is expected that Next-Generation DTV broadcasting can provide a sensation of reality and presence with extremely higher quality and three-dimensional contents such as UHD and 3D video/audio. In this research, ETRI has been researching on realistic broadcasting core technology, providing a rich sensation of reality and presence to users with cinema-quality multimedia, multi-view video, super high resolution video of 4~16 times higher than that of HDTV video, and multi-channel audio and 3D audio associated with the video. In order to do this, stereoscopic 3D DMB and multi-view 3DTV broadcasting technology for 3D applications, AV coding and transmission technology for UHDTV, high-efficiency AV coding technology for mobile applications, and multi-channel/multi-object based realistic audio technology for 3DTV and UHDTV have been researched. Also, domestic and international standardizations for AV coding and transmission technology, and application format for multimedia have been carried out.
Compared to the classic AV centric multimedia services, rich media services provide attractive characteristics including dynamic updates of contents and interactivities among various forming multimedia data such as audio, video, graphics and text. The demand for such rich media service is increasing at a high pace spurred by the development of the next generation infrastructure and the increased reusability of TV contents applying to new media such as terrestrial DTV contents are retransmitting to IPTV.
Several technologies are competing to achieve the rich media service such as BiFS, LASeR, Flash, etc. Convergence Service Research Team has been developing an MPEG-4 LASeR based platform for creating and consuming the rich media contents. Moreover, various supporting technologies of the interactive rich media solution for convergence services such as IPTV, Web TV and mobile TV are exploited.
In addition, Convergence Media Research Team has developed interactive view control technologies for IPTV service. By interactive view control, IPTV users can control his/her view-point of interests by him/her self on multi-view or panoramic video service.
ETRI is developing Protection Technology for Terrestrial DTV Program to ensure the profit of the broadcasting industry, establish transparent distribution systems, and promote the digital broadcasting in Korea. This technology will guarantee Fair-Use of the programs as well as copyrights, so that high-quality HD programs and a variety of digital broadcasting services will be provided.
For Development of Protection Technology for Terrestrial DTV Program, ETRI is making progress in development and standardization of the terrestrial DTV program protection system, including technologies for transmission of broadcast stream, End-user terminals, recording/storing/copy control methods and redistribution/retransmission prevention methods, which provide significant functions of preventing illegal use of the terrestrial DTV programs.
ETRI is developing broadcasting content distribution service framework technology using national standard content identification to establish the infrastructure of broadcasting content service industry and revitalize overall industry of cultural contents. This technology, using national standard content identification, will provide the management technology for the broadcasting content ecosystem, which covers end-to-end life-cycle of broadcasting contents including creation·transmission·consumption·distribution, so that the profit of content industry will be ensured by well-organized copyright protection and management.
For development of this Technology, ETRI is making progress in development and standardization of broadcasting content distribution service framework including creation·transmission·consumption·distribution technologies, which are correlated using national standard content identification
User-created music service means a music service of new concept that users can interact with characteristics of individual tracks (instruments) composing a music and its whole characteristics such as rhythm, genre, etc and hence create their own music contents by controlling the provided characteristics of the music.
In order to do this, the core music signal processing technology, including separation technology of wanted instrument tracks, like vocal, drum (rhythmic component), and the remaining harmonic component, from general stereo-format music signal, coding and decoding technology of multiple objects (tracks), and technology to control of music mood, will be developed.
Also, in order to verify the developed technology, a technology-verifying prototype system, composing of an authoring tool and a terminal player, will be developed. The figure below shows a conceptual diagram of this service.
