Problems solved by technology

However, in case each base station 120A-120N uses a separate channel, frequency resources may be wasted
Furthermore, in the case of preventing the communication ranges of the respective base stations from overlapping, an area where the broadcast receiver cannot receive any broadcast signal from the respective base stations 120A-120N inevitably occurs

Embodiment Construction

[0030] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0031] According to the digital broadcasting system of the embodiment of the present invention, a broadcasting station is provided with a multiplexer for broadcasting packets, and a base station is provided with respective transceivers (ie, transmitters and receivers). When a broadcasting station provided with a multiplexer transmits broadcast packets to base stations provided with transmitters respectively, the multiplexer and the transmitters share information on a start packet indicating the start of a frame so that the transmitters of the respective base stations form the same frame.

Abstract

A digital broadcasting system and a data processing method thereof are provided. An apparatus for generating a transport stream includes a packet generator for generating a plurality of packets by compressing video and audio signals; a counter for counting the number of the generated packets and outputting the count result; and an information controller for determining whether the count result ofcounting reaches a predetermined number of packets, inserting packet start information into the packets according to the count result, and transmitting the packets with the packet start information inserted therein. The packet start information is added to a packet to be transmitted in a transmitter, and the packet start information is extracted from the received packet in a receiver, so that thewaste of frequency resources can be reduced.

Description

[0001] This application is a divisional application of a patent application with an application date of March 30, 2007, an application number of 200780010887.0, and a title of "Digital Broadcasting System and Its Data Processing Method". technical field [0002] The present invention relates to a digital broadcasting system and a data processing method thereof, and more particularly, to a digital broadcasting system and a data processing method capable of reducing waste of frequency resources through efficient transmission and reception of packets. Background technique [0003] Recently, the type of television (TV) broadcasting has suddenly changed from analog to digital, and broadcasting systems such as Koreaset in Korea, DirecTV in the United States, PerfecTV in Japan, etc. have adopted the digital television (DTV) system. In terrestrial broadcasting, ATV (Advanced TV) in the United States and DVB (Digital Video Broadcasting) in Europe are rapidly promoting digital TV broad...
