Problems solved by technology

[0005] That is, in recent years, packets transmitted in various heterogeneous networks are significantly different in packet error rate received according to the transmission channel state, and in this case, it is difficult for the existing technology to provide Optimal EFC processing for
[0006] Also, in the case of mixed delivery in which an AV stream is transmitted through a broadcast network and additional information is transmitted through a broadband network, packets transmitted through different networks are also significantly different in packet error rates received according to the transmission channel state, and in this In this case, the best FEC processing using channel state reflection cannot be provided in the prior art

Abstract

A method for adaptively transmitting FEC parity data using cross-layer optimization is provided. More specifically, the present invention relates to a method for transmitting multi-media through adaptive control of the FEC parity using cross-layer optimization which comprises a step of determining a size of the FEC parity data set by using channel state information received from a lower layer. [Reference numerals] (AA) Transmitting PHY channel state information to application FEC(Closs Iayer Optimization)

Description

technical field [0001] The present invention relates to a method for transmitting FEC parity data, and more particularly, to a method for adaptively transmitting FEC parity data according to a channel state. Background technique [0002] Following the standardization of MPEG-2 as a video compression standard (alternatively, an audio compression standard), new standards such as MPEG-4, H.264 / AVC, Scalable Video Coding (SVC), etc. New corresponding standards have also broadened the application field of MPEG standards while forming new markets, however, transmission technologies such as MPEG-2 Transmission System (TS) have always been widely used in the market during the past nearly 20 years. It is used for digital broadcasting, mobile broadcasting (T-DMB, DVB-H, etc.) and is still widely used in multimedia delivery over the Internet, ie IPTV services were not considered when this standard was established. [0003] However, today's multimedia delivery environment has changed ...
