    摘要： Disclosed are an IPTV, and a content-downloading method for the IPTV. The content-downloading method of the IPTV, according to one embodiment of the present invention, comprises the steps of: accessing an IPTV network and receiving Service Discovery and Selection (SD&S) information containing Open Internet Content Delivery (OICD) service information; parsing the OICD service information to obtain location information of an OICD provider; and accessing the OICD provider via the location information of the OICD provider, wherein said OICD service information contains the location information of the OICD provider which provides network information for downloading content using a peer-to-peer scheme. In addition, the IPTV receiver, according to one embodiment of the present invention, comprises: a network interface which accesses the IPTV network and receives Service Discovery and Selection (SD&S) information containing Open Internet Content Delivery (OICD) service information; a PSI decoder which parses the OICD service information to obtain the location information of the OICD provider; and a service access unit which accesses the OICD provider via the location information of the OICD provider, wherein said OICD service information contains the location information of the OICD provider which provides network information for downloading content using a peer-to-peer scheme.

    摘要： According to one embodiment of the present invention, a method for transmitting an IPTV streaming service by P2P transmission comprises the steps of collecting TS packets of n skipped units to generate an encapsulation unit for an IPTV streaming service (where n is a natural number); adding an extension header containing type information to the generated encapsulation unit (wherein, said type information is information for identifying the sequence of the encapsulation unit, which is required for decoding the IPTV streaming service); adding an IP header to the encapsulation unit to which the extension header containing the type information is added, in order to generate an IP packet; and transmitting the generated IP packet to at least one super peers.
