Abstract

A digital broadcast receiving apparatus and a method thereof are disclosed. The digital broadcast receiving apparatus includes a demultiplexer for separating a multichannel transport stream into a plurality of broadcasting channel data and outputting the broadcasting channel data, a buffer unit, including a plurality of buffers having different capacities that correspond to data bit rates, for storing the broadcasting channel data in the buffers having the corresponding capacities, respectively, according to the data bit rates, a user interface for outputting channel identification information corresponding to the broadcasting channel selected by a user, and a switching device for selecting one of outputs of the plurality of buffers according to the channel identification information.

Description

technical field [0001] The present invention relates to a digital broadcast receiving device and method thereof. Background technique [0002] With the development of digital broadcasting technology and communication technology, providing digital broadcasting to mobile users has become a growing concern. Digital Multimedia Broadcasting (hereinafter referred to as 'DMB') is a broadcast service that allows users to watch different multimedia broadcasts on multiple channels using a personal portable receiver or a mobile vehicle receiver. In particular, the CDM (Code Division Multiplexing) technique for CDMA mobile phones similar to the standard Rec. BO.1130-4: System-E of ITU (International Telecommunication Union) is selected for satellite DMB in Korea. [0003] In an existing digital broadcast receiving apparatus, before a program is provided to a user through an indicator and a display unit, a buffer is filled with broadcast program data. The time required to actually watc...
