World’s First Terrestrial DMB Receiver Developed By SAMSUNG Electronics

SAMSUNG Electronics has completed development of a unique receiver dedicated to terrestrial digital multimedia broadcasting (DMB), a service integrating broadcasting and communications. The new product is the first to commercialize both H.264 digital video and MPEG-4 BSAC digital audio coding technologies, offering further testimony to SAMSUNG’s digital technology leadership.

The Korean government has designated DMB as one of the ten most important next-generation growth drivers. In addition to government-sponsored research, many domestic DMB-related companies are working hard on hardware and software solution development.

SAMSUNG Electronics’ new DMB receiver is compatible with the domestic terrestrial digital multimedia broadcasting transmission and reception standards instituted at the Next-generation Broadcasting Forum. It encompasses core technologies for next-generation multimedia such as H.264. The successful development project boosts SAMSUNG’s international standardization activities and technology development effort and offers the possibility of obtaining core intellectual property rights.

The DMB standards use the terrestrial H.264 and MPEG-4 BSAC standards decided upon at the Next-generation Broadcasting Forum held last May. Various multimedia broadcasting services are offered, and the system supports data broadcasting that enables interactive dialogue via MPEG-4 BIFS.

During the work on deciding a DMB standard, the experts said service would be delayed at least until the end of 2004 due to a lack of commercial H.264 and BSAC solutions, which are key technology considerations. They now say, however that, SAMSUNG Electronics’ newly commercialized receiver and core technology development open the door for Korea to become the world’s first to offer commercialized terrestrial DMB service.

A spokesperson at the SAMSUNG Electronics Digital Media R&D Center says a portable DMB receiver and multifunctional products that include a DMB receiver are also under development.

Digital Multimedia Broadcasting
The Korea Broadcasting Commission and Ministry of Information & Communication applied the name “Digital Multimedia Broadcasting” (“DMB”) to the new service development model encompassing video services standardized to launch the new “domestic microwave digital radio broadcasting” service. This Korean version of the European Digital Audio Broadcasting (DAB) adds new functions to DAB such as video protection algorithm, audio protection algorithm, multi-channel and external protection.

H.264 (ITU-T Rec. H.264 / ISO/IEC 14496-10 AVC: Advanced Video Coding for Generic Audiovisual Services)
This new video compression standard was established by ITU-T and MPEG in 2003 and has been selected as the basic video codec for the Korean DMB. Since MPEG-2 (H.262), all new video codec technology has been chosen as a standard shared by both ITU and MPEG. It is called H.264 by the ITU and MPEG-4 Part 10 by MPEG. No commercial solution exists to date, but the new technology boasts a far better compression ratio than the current standard video compression codec.

BSAC (Bit Sliced Arithmetic Coding): ISO/IEC 14496-3
This is one of the MPEG-4 Part 3 audio coding technologies. Scalable transmission in bit units is possible when sending data over wireless and wireline networks using the basic MPEG-4 Advanced Audio Coding algorithm.
BIFS (Binary Format for Scene): ISO/TEC 14496-1
Part of the MPEG-4 system, this technology compresses graphics, data for scene layout and data for audio/video interactivity in a binary format for broadcasting. Thus, graphics, and interactive data can be broadcast along with audio and video data.
