This paper briefly introduces the T-DMB standard based on Eureka-147 DAB and presents a new T-DMB transmission system, which uses a device called the Ensemble Remultiplexer, for mobile multimedia broadcasting service. And we verify the T-DMB standard by using the new transmission system with commercial equipment in the laboratory and in the field as moving on a car in high speed around urban districts surrounded by high buildings.

To meet the needs of various consumers and reuse of digital broadcasting programs, it is necessary to re-transmit the digital broadcasting program produced by a variety of digital broadcasting standards over the different digital broadcasting systems. Especially, some channels in digital terrestrial broadcasting must be re-transmitted through the digital cable broadcasting in Korean digital broadcasting environment. In this paper, we present two possible methods for re-transmission from the digital terrestrial broadcasting to digital cable broadcasting, and propose a real-time re-transmission system.

This article proposes a dynamic linkage service which is a specific service model of integrated broadcast — broadband services based ATSC 3.0. The dynamic linkage service is useful to the viewer who wants to continue watching programs using TV or their personal devices, even after the terrestrial broadcast ends due to the start of the next regular programming. In addition, we verify the feasibility of the proposed extended dynamic linkage service through developed emulation system based on ATSC 3.0. In consideration of the personal network capabilities of the viewer environment, the service was tested with 4K/2K Ultra HD and receiving the service was finished within 4 second over intranet.
