Abstract

In the present invention, an apparatus for DAB reception and a method for DMB reception thereof are disclosed. According to the present invention, the DAB receiving apparatus comprises: a demultiplexer which determines a video format by using information data extracted from the DAB; a video decoder, which is a software decoder, for decoding a video image of a frame of the DAB with reference to the video format; a JPEG encoder, which is a software encoder, to encode the decoded video image into a JPEG standard to transfer to a data interface; and a JPEG decoder which receives the JPEG standard video image through the data interface and transmits to a display unit by decoding the JPEG. [Reference numerals] (110) RF receiving unit; (120) Base band unit; (130) Channel decoder; (140) Demultiplexer; (150) Audio decoder; (160) Video decoder; (170) JPEG encoder; (210) JPEG decoder

Description

technical field [0001] The present invention relates to a digital audio broadcasting (Digital Audio Broadcasting, hereinafter referred to as DAB) broadcast receiving device, in particular to a DAB broadcast receiving device capable of receiving Digital Multimedia Broadcasting (Digital Multimedia Broadcasting, hereinafter referred to as DMB) and a DMB broadcast receiving method thereof . Background technique [0002] In general, DAB broadcasts in Europe are standard broadcasts produced by digitizing FM analog broadcasts. [0003] Existing DAB broadcasts are almost dominated by DAB Audio (MP2; Digital Broadcasting Audio Codec), and, recently, there is provided a DMB-AUDIO standard similar to the DMB broadcast format using the DAB+ (AACV2; Audio Codec) standard Audio broadcasts including video broadcasts, etc. [0004] Therefore, existing audio-based DAB broadcast receivers that can only receive audio broadcasts are being developed into audio / video compatible DAB broadcast re...
