areas for Research & Development

Digital CATV Technology

Overview

We have been developing IP-based high speed multimedia transmission system and next generation digital cable transmission system to increase the efficiency of cable frequency resource, promote the smooth conversion from analog to digital broadcasting for HFC, and contribute to introduction of various cable services. The IP-based high speed multimedia transmission system will provide various broadcasting, telecommunication, and converged services through HFC network in near future.

Major R&D Fields

IP based high speed multimedia transmission system for HFC network

Development of 200Mbps upstream transmission technologies
Development of high speed multimedia transmission system for HFC network
Domestic/International standardization activities

Terrestrial DTV Technology

Overview

We are developing broadcasting repeater/translator system to extend coverage and cover shaded area where broadcasting signal can’t reach. Frequency efficient and easy to construct broadcasting network will promote smooth transition from analog to digital, highly efficient use of terrestrial broadcasting frequency and new multimedia services. Moreover, advanced data transmission technology and service which is backward compatible with ATSC terrestrial DTV will be developed and tested in the field.

Major R&D Fields

Development of DTV translator system that enables efficient use of frequency and ease construction of broadcasting network

Development of DTV translator system

Development of distributed translator (commercial prototype)
Development of translator ID analyzer (commercial prototype)
Experimental broadcasting of Distributed Frequency Network

Development of transmission efficiency enhancement technology for terrestrial DTV system which is backward compatible with legacy ATSC terrestrial DTV(8-VSB)

Development of additional data transmission system
Development of additional data receiver
Trial broadcasting of additional data transmission/receiving system

3DTV Broadcasting Technology

Overview

3DTV is being considered as one of next generation broadcasting technology because it can satisfy the demands of human-beings for the realistic broadcasting service which is able to provide depth as well as reality. We are aiming to ensure and standardize essential 3D broadcasting technologies obtained during the development of 3D video acquisition and pre-processing, encoding/decoding/multiplexing, transmission, 3D display, and non real-time broadcasting services.

Major R&D Fields

Development and standardization of broadcasting technologies for glass-free 3D broadcasting service in fixed/mobile environment

Development of stereoscopic 3D DMB broadcasting technology
Terrestrial stereoscopic 3DTV broadcasting systems technology
Glass-free multi-view 3DTV broadcasting technology
Standardization of 3D video core technologies

Next Generation Mobile Broadcasting Technology

Overview

We have been developing digital mobile multimedia broadcasting technologies for high quality video and audio keeping backward compatibility with the T-DMB system. With a hierarchical modulation technology, enhanced data rate is possible for the T-DMB in the same frequency bandwidth. And also with a scalable video coding and a MPEG surround technology high quality video/multichannel audio service becomes possible, which can satisfy mobile receivers in the near future market.

Major R&D Fields

Increased Data-rate technology for the T-DMB

High efficiency/high quality transmission/reception system technology development keeping backward compatibility with the T-DMB system for SD quality video and multi-channel audio services.

Increased Data-rate technology for the T-DMB
