Method and apparatus for providing internet protocol datacasting (IPDC) service, and method and apparatus for processing IPDC service

摘要

Provided are a method and apparatus for providing an Internet Protocol Datacasting (IPDC) service. The IPDC service providing apparatus includes a data input unit generating an IP packet and signaling information of the IP packet; a packet generation control unit determining a type of an Internet Protocol Data Group (IPDG) packet that is to be generated by encapsulating the IP packet, on the basis of characteristics of the IPDC service; an IPDG packet generation unit generating an IPDG packet according to a data type of the IP packet, and generating an IPDG packet for the signaling information of the IP packet; a transfer stream packet generation unit generating the IPDG packet as a transfer stream packet; and a transfer unit transmitting the transfer stream packet. Accordingly, it is possible to provide an IPDC service while efficiently using a bandwidth, in a Digital Audio Broadcasting (DAB) system.
