METHOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR PROVIDING MULTIMEDIA DATA BASED ON NETWORK CODING

摘要

The present invention relates to a method, a system and a computer readable recording medium for transmitting multimedia data based on network coding. According to an aspect of the present invention, there is provided a method for transmitting data based on network coding, comprising: (a) classifying information into a plurality of groups based on a priority according to a request of a user terminal device; Transmitting, to the user terminal device, a group having a higher priority than a predetermined threshold among the groups of (c), and (c) network coding a group having a lower priority than the predetermined threshold among the plurality of groups. Provided is a method comprising transmitting to the user terminal device. Accordingly, another object of the present invention is to classify information according to priority and to transmit the classified information as information that is not network coded and network coded according to priority.;Network coding, priority, IPTV, multicast
