Problems solved by technology

Since the same frequency cannot be used in the regions of short distance due to the generation of interference, the conventional technology is very inefficient in the aspect of using frequencies.
However, if digital television (TV) broadcasting is operated using a conventional digital TV transmission system, many problems occur.
Therefore, when the signals are broadcasted on a single frequency network, the output signals cannot be discriminated.
That is, if the signals transmitt

Embodiment Construction

[0026] Other objects and aspects of the invention will become apparent from the following description of the embodiments with reference to the accompanying drawings, which is set forth hereinafter.

[0027]FIG. 4 is a schematic diagram illustrating a terrestrial digital broadcasting service system using a single frequency network in accordance with a preferred embodiment of the present invention. Referring to FIG. 4, a broadcasting station 400 multiplexes video, voice and additional data signals to generate transport stream (TS) and transmits TS to a first transmitting station 430 and a second transmitting station 470. The first transmitting station 430 and the second transmitting station 470 process the TS and broadcast the TS on the same transmission frequency A to a first broadcast coverage 450 and a second broadcast coverage 490.

[0028] The terrestrial digital broadcasting system using a single frequency network, which is an American style, is illustrated in FIG. 5. FIG. 5 is a bl...

Abstract

Provided is a system and method for terrestrial digital broadcasting service using a single frequency network without additional equipment. The system and method synchronizes input signals into transmitting stations by inserting a transmission synchronization signal into a header of TS periodically, and solves the problematic ambiguity of the trellis encoder by including a trellis encoder switching unit separately and initializing a memory of the trellis encoder. The terrestrial digital broadcasting system includes: a broadcasting station for multiplexing video, voice and additional signals into transport stream (TS) and transmitting the TS to the transmitting stations and a transmitting stations for receiving the TS and broadcast the TS to receiving stations through a single frequency network

Description

FIELD OF THE INVENTION [0001] The present invention relates to a system and method for providing terrestrial digital broadcasting service using a single frequency network; and, more particularly, to a system and method where a plurality of transmitting stations provide a terrestrial digital broadcasting service through a single frequency network. DESCRIPTION OF RELATED ART [0002] In general digital broadcasting service systems, transmitting stations are positioned based on the natural configurations, natural features and broadcasting coverage, and broadcasting data are transmitted in a frequency band allocated to each transmitting station, which is called a plural frequency network mode. [0003]FIG. 1 is a schematic diagram illustrating a typical terrestrial digital broadcasting service system. Referring to FIG. 1, a broadcasting station 100 multiplexes video, voice and additional data signals and transmits multiplexed signals in the form of a predetermined type of packet, i.e., tran...
