Problems solved by technology

[0004] However, according to the TSC A97 standard, the Download Information Description (DII) corresponds to one model of the digital broadcast receiver, and the number of modules having upgrade software that can be supported by the data carousel is limited
[0005] Furthermore, when there are files shared by modules of the same manufacturer, each module uses the DII, so data must be sent redundantly, causing bandwidth inefficiencies Use and incremental costs

Abstract

Provided are a method of upgrading software by using a common module shared by a plurality of models, and a digital broadcast receiver therefor. The method includes receiving a digital broadcast signal which contains a common module shared by a plurality of models of the digital broadcast receiver, separately from a unique module of the digital broadcast receiver; determining whether to upgrade each module of the digital broadcast receiver, when it is determined that software upgrading is needed, according to predetermined update information; and collecting DownloadDataBlocks (DDBs) for a module, which is to be upgraded, from the received digital broadcast signal, in order to form a module. The common module is transmitted in the form of a group different than a group to which the common module belongs or in the form of another group, thereby saving bandwidth for software upgrading.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0100008 filed on October 13, 2006 at the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference. technical field [0002] The method and apparatus according to the present invention relate to upgrading software and digital broadcasting receivers thereof by using a common module shared by various models. Background technique [0003] With the widespread spread of terrestrial digital broadcasting, there is an increasing demand for upgrading complex software for digital broadcasting receivers. To upgrade terrestrial digital broadcasting, a standard for upgrading software for digital broadcasting receivers by using a data carousel, such as the ATSC A97 standard, is used. [0004] However, according to the TSC A97 standard, a Download Information Description (DII) corresponds to one model of a digital broadcast receiver, and the number of modules having upg...
