Abstract:
1. An apparatus for transmitting an IPTV streaming service by P2P transmission, comprising: a first generator to collect m*n TS packets to generate n encapsulation units for the IPTV streaming service (where m and n are natural numbers); an error check code generator to generate an error detecting stream packet including error check codes, wherein each of the error check codes are generated for every n TS packets; a first controller to add an extension header containing type information to the generated encapsulation units and the generated error detecting stream packet, wherein the type information includes information for identifying the order of the encapsulation units, which is required for decoding the IPTV streaming service, information for representing a super peer to which the one of the generated encapsulation units or the generated error detecting stream packet is to be transmitted and information for identifying the error detecting stream packet; a second generator to add an IP header to the encapsulation unit and the error detecting stream packet to which the extension header containing the type information is added, in order to generate an IP packet; and a transmitter to transmit the generated IP packet to corresponding super peer based on the type information by unicast.
