Abstract

A transmission device and receiving device for providing high-quality multimedia services in a digital multimedia broadcasting (DMB) transmission system is provided. The transmission device separatesinput multimedia contents into a base layer elementary stream and an enhancement layer elementary stream, encodes the base layer elementary stream and the enhancement layer elementary stream, transforms the base layer elementary stream and the enhancement layer elementary stream into a base layer SL packet and an enhancement layer SL packet, transforms the base layer SL packet and the enhancementlayer SL packet into a base layer PES packet and an enhancement layer PES packet, and multiplexes the base layer PES packet and the enhancement layer PES packet according to a base layer elementary stream and an enhancement layer elementary stream and outputs a base layer TS packet and an enhancement layer TS packet.

Description

technical field

[0001] The present invention relates to a media processing method and device for providing high-quality multimedia services, by using the method and device, functions for providing high-quality services are added to digital multimedia broadcasting, and backward compatibility with existing receivers can be maintained sex.

[0002] This invention arose out of a research project supported by the Information Technology (IT) Research and Development (R&D) Program of the Ministry of Information and Communications (MIC) [2006-S-017-02, Development of High-Tech Terrestrial DMB Transmission]. Background technique

[0003] In conventional digital multimedia broadcasting (DMB), multimedia services are multiplexed into a single transport stream and the multiplexed services are delivered. In DMB broadcasting, multimedia services are provided through a single stream, and thus there is a limit in providing high-quality services. Description of drawings
