Iptv service provision method and system for fixed and mobile devices

An Internet Protocol TeleVision (IPTV) service provision method comprising:

• discovering, when an IPTV terminal including a first Open IPTV Terminal Function (OITF) having a plurality of functional entities and an embedded gateway having a plurality gateway functions detects a gateway function of an IPTV Terminal Function (ITF) including a second OITF having a plurality of functional entities and a plurality of gateways, the gateway function of the ITF;
• establishing a link with the ITF by means of the gateway function of the ITF;
• disabling the embedded gateway;
• transmitting a service request message in a Hyper-Text Transfer Protocol (HTTP) format to the gateway function of the ITF;
• transmitting the service request message in a Session Initiation Protocol (SIP) format from the gateway function to a service provider network;
• transmitting a service response message in an SIP format from the service provider network to the gateway function of the ITF;
• and
• receiving the service response message in an HTTP format from the gateway function of the ITF;
• and
• receiving an IPTV service provided by the service provider network via the ITF.

An Internet Protocol (IP) TeleVision (IPTV) service provision system comprising:

• an IPTV terminal including a first Open IPTV Terminal Function (OITF) having a plurality of functional entities and a plurality of gateways, the IPTV terminal being connected to a service provider network to provide an indoor IPTV service;
• and
• a IPTV Terminal Function (ITF) including a second OITF having a plurality of functional entities and an embedded gateway having a plurality gateway functions;
• wherein the ITF establishes, when the gateway function is detected, a link with the gateway function of the ITF, disables the embedded gateway, receives the IPTV service provider by the service provider network via the ITF, enables, when a detachment of the ITF from the gateway function is detected, the embedded gateway, connects to the service provider network using the embedded gateway, and receives the IPTV service from the service provider network.

An Internet Protocol (IP) TeleVision (IPTV) service provision method comprising:

• discovering, when a device supporting a broadcast service detects a gateway function of an IPTV Terminal Function (ITF) including an Open ITF (OITF) having a plurality of functional entities, a plurality of gateways, and an adaptation gateway, the gateways of the ITF;
• establishing a link to the ITF by means of the adaptation gateway;
• transmitting a service request message in a Hyper-Text Transfer Protocol (HTTP) format from the device to the adaptation gateway;
• establishing ADaPtation (ADP) interfaces between the adaptation gateway and the gateways of the ITF;
• transmitting the service request message in a Session Initiation Protocol (SIP) format from the adaptation gateway to a service provider network;
• transmitting a service response message in an SIP format from the service provider network to the adaptation gateway;
• receiving the service response message in an HTTP format from the adaptation gateway;
• and
• receiving an IPTV service from the service provider network via the ITF.
