Problems solved by technology

The advantage of VSB as a standard for terrestrial DTV reception is that it increases the utilization of the frequency band, thereby maximizing the range of DTV viewing. The disadvantage is that it is difficult to apply VSB to mobile TV due to the difficulty of receiving radio signals during sports

Abstract

[Problem] It is hard to apply the A-VSB transport system to a mobile broadcast. [Solution] Provided are a method and apparatus for transporting a broadcast and a method and apparatus for receiving a broadcast. In the method of transporting a broadcast service for mobile communications, the method includes generating an encapsulation packet including configuration information adaptive to application data that is to be transmitted and the application data; generating transport packets having data regarding the encapsulation packet by dividing the encapsulation packet into predetermined-sized packets, where the transport packets include information regarding the structures of the transport packets; and generating service configuration information including information set about a channel having the transport packets, and including the service configuration information in a service information channel at a predetermined location from among at least one transport channel on a transport stream. Accordingly, it is possible to efficiently use a data region and increase the speed of data transmission.

Description

technical field [0001] The present invention relates to a method and device for transmitting broadcast and a method and device for receiving broadcast, and more particularly, to a broadcast transmitting method and device for providing mobile broadcast service. Background technique [0002] ATSC (Advanced Television Systems Committee) is an organization that defines digital television (DTV) transmission standards in the United States of America among terrestrial digital television (DTV) broadcast transmission standards. The main points of the standard defined by ATSC relate to audio / video (AV) compression and transmission. That is, video signals are compressed according to the MPEG2 standard, sound and speech signals are compressed according to the AC-3 standard, and these signals are transmitted using a vestigial sideband (VSB) technique. The advantage of VSB as a standard for terrestrial DTV reception is that it increases the utilization of frequency bands, thereby maximiz...
