In step S105, the IPTV service server 100 transmits provisioning environment information matching the IPTV terminal 200 to the IPTV terminal 200.

The provisioning environment information includes the identification information of the IPTV service provider subscribed to by the user of the IPTV terminal 200, the transmission method of the IPTV service discovery information, that is, a push method or a pull method, and the IPTV service discovery information. It may include the transport address of.

In addition, the provisioning environment information may include identification information of a package including information on an IPTV service product, a service area, etc., to which a user of the IPTV terminal 200 subscribes, and identification information of a segment in which the corresponding package is located.

In step S110, the IPTV terminal 200 sets an IPTV service provisioning environment based on the provisioning environment information received in step S105.

In step S115, the IPTV service server 100 generates service information provided to one or more IPTV terminals receiving the IPTV service.

The service information includes identification information of the IPTV service provider and one or more individual service information provided by the service provider.

The individual service information may include information such as service identification information, an address where a transport stream of a corresponding service is provided, a serviceable area, and a service name.

The address provided with the stream among the information included in the individual service information may include a multicast address of the stream or an address of the stream providing server 300 according to the stream transmission method by the stream providing server 300.

That is, when a transport stream of an individual service is transmitted by the stream providing server 300 in a multicast manner, the individual service information may include a multicast address of the transport stream.

In addition, when a transport stream of an individual service is transmitted by the stream providing server 300 in a unicast manner, the individual service information may include an address of the stream providing server 300 transmitting the transport stream.

In step S120, the IPTV service server 100 generates information of a package including one or more services provided to one or more IPTV terminals provided with the IPTV service.

The package information includes package identification information and one or more service reference information. The service reference information may include service identification information and channel information matching the corresponding service.

In step S125, the IPTV service server 100 generates service search information including service information, package information, and operator information generated in steps S115 and S120.

The operator information may include operator information, identification information of a service provided by the operator, and the like.

Service information, package information, service provider information, and service search information generated by the IPTV service server 100 may be generated and encoded through XML (eXtensible Markup Language) proposed by the W3C (world wide web consortium).

In step S130, the IPTV service server 100 transmits the service discovery information generated in step S125 to the IPTV terminal 200.

The IPTV service server 100 may transmit the service discovery information generated in step S125 to the IPTV terminal 200 using a push method or a pull method. 1 illustrates a case in which service discovery information is transmitted in a push manner as described above, and in a description of another embodiment of the present invention with reference to FIG. The case of transmitting is described.

When the service discovery information is transmitted in a push manner, the IPTV service server 100 performs IPTV service discovery information in a multicast manner through the DVB Service Discovery & Selection Transport Protocol (DVBSTP) protocol or the File Deliver over Unidirectional Transport (FLUTE) protocol. It may be transmitted to the terminal 200.

In particular, the IPTV service server 100 transmits service discovery information to the IPTV terminal 200 through DVBSTP (ETSI TS 102 034, a light protocol specified by DVB, used for delivery over multicast) protocol, and FLUTE (IETF RFC 3926) protocol. Can transmit

The IPTV terminal 200 may receive service discovery information transmitted by the IPTV service server 100 in a multicast manner by using the transport address of the IPTV service provider included in the provisioning environment information set in step S110.

That is, the IPTV terminal 200 obtains the multicast address information from the transport address of the IPTV service provider included in the provisioning environment information set in step S110 and joins the obtained multicast address to obtain the IPTV service discovery information. Can be.

IPTV terminal 200 is Internet Group Management Protocol (IGMP), in particular IGMP version 2 (IETF RFC 2236 for "Detailed Service Offer" delivery over IPv4 multicast (push mode)), IGMP version 3 (IETF RFC 3376 for "Detailed Service Offer) IPTV service discovery information may be obtained by joining to a multicast address using "delivery over IPv4 multicast (push mode)".

In step S135, the IPTV terminal 200 obtains package information matching the user of the IPTV terminal 200, that is, the subscriber of the IPTV service, from the service search information received in step S130.
