Abstract

Provided is a Digital Multimedia Broadcasting (DMB) transmitting / receiving apparatus. The DMB apparatus for a high-quality video service includes: a source encoder for source-encoding audio and video signals into base layer streams and enhancement layer streams, individually; a base layer transmission processor for receiving the base layer streams from the source encoder, performing system encoding, multiplexing encoded base layer streams into transport streams, and outputting base layer transport streams; an enhancement layer transmission processor for receiving the enhancement layer streams from the source encoder, performing system encoding, multiplexing the encoded enhancement layer streams into enhancement layer transport streams, and outputting enhancement layer transport streams; and a layered digital broadcasting transmitter for receiving the base layer transport streams and the enhancement layer transport streams from the base layer transmission processor and the enhancement layer transmission processor, and modulating the base and enhancement layer transport streams into digital broadcasting signals.

Description

technical field [0001] The present invention relates to a digital multimedia broadcasting (DMB) transmission / reception device for high-quality video services; and more particularly, to a DMB transmission / reception device capable of providing High-quality video services or additional services. Background technique [0002] figure 1 is a block diagram illustrating a conventional Digital Multimedia Broadcasting (DMB) transmission device. [0003] like figure 1 As shown, a conventional DMB transmission device includes a Moving Picture Experts Group 4 (MPEG-4) video encoder 111, an MPEG-4 audio encoder 113, an MPEG-4 systems encoder 120, an MPEG-2 transport stream (TS) multiplexer A user 130, a Reed-Solomon (RS) encoder 140, a convolutional interleaver 150, and a digital audio broadcasting (DAB) transmitter 160. MPEG-4 video encoder 111 and MPEG-4 audio encoder 113 encode video and audio sources. The MPEG-4 systems encoder 120 objectsizes and synchronizes the media streams, ...
