Abstract
A method of processing data in an IPTV receiver and such an IPTV receiver are disclosed. The method includes receiving location information necessary to acquire a content corresponding to a content reference identifier (CRID) by using the CRID, requesting an Internet protocol multimedia subsystem Gateway (IG) to transmit a session description protocol (SDP) file of the content, wherein the content is identified by the CRID and an instance metadata identifier (IMI), receiving the requested SDP file from the IG, and controlling a session setup for processing the content by using the received location information and the received SDP file.
Claims7
A method of retrieving at least one parameter of a SDP (session description protocol) file prior to a session setup in an open IPTV terminal function (OITF) receiver, the method comprising:
- performing a content reference identifier (CRID) location resolution process of mapping a CRID to either other CRIDs or a location information, wherein the location information provides additional data to retrieve the content;
- retrieving the at least one SDP parameter prior to the session setup, the retrieving comprises,
- firstly requesting by the OITF receiver to an Internet protocol multimedia subsystem Gateway (IG) on a home network interface-IG interface (HNI-IGI) interface, the at least one SDP parameter;
- secondly requesting by the IG to a network, the at least one SDP parameter, wherein the content is identified by at least one of CRID and Instance Metadata Identifier (IMI);
- retrieving, by the IG, the at least one SDP parameter from the network;
- forwarding the at least one SDP parameter from the IG to the OITF receiver;
- and
- performing the process of the session setup after the OTIF receiver has retrieved the at least one the SDP parameter,
- wherein the CRID location resolution process further comprises:
- transmitting the CRID to a location resolution server;
- and
- receiving other CRIDs or location information based on a content referencing table from the location resolution server.
An open IPTV terminal function (OITF) receiver that retrieves at least one parameter of a SDP (session description protocol) file prior to a session setup, the OITF receiver comprising:
- a first performing unit configured to perform a content reference identifier (CRID) location resolution process of mapping a CRID to either other CRIDs or a location information, wherein the location information provides additional data to retrieve the content;
- a retrieving unit configured to retrieve the at least one SDP parameter prior to the session setup, the retrieving comprises:
- firstly requesting by the OITF receiver to an Internet protocol multimedia subsystem Gateway (IG) on a home network interface-IG interface (HNI-IGI) interface, the at least one SDP parameter;
- secondly requesting by the IG to a network, the at least one SDP parameter, wherein the content is identified by at least one of CRID and Instance Metadata Identifier (IMI);
- retrieving, by the IG, the at least one SDP parameter from the network;
- forwarding the at least one SDP parameter from the IG to the OITF receiver;
- and
- a second performing unit configured to perform a process of the session setup after retrieving the at least one SDP parameter,
- wherein the CRID location resolution process further comprises:
- transmitting the CRID to a location resolution server;
- and
- receiving other CRIDs or location information based on a content referencing table from the location resolution server.
