series is based on a series of specifications that was originall y developed by the Open I PTV Forum (OI PF) They specify the user-to-network interface (UN I ) for consum er term inals to access I PTV and open internet m ultimed ia services over m anaged or nonmanaged networks as defined by OI PF The Open I PTV Forum (OI PF) I PTV solution provides specifications for an end-to-end platform for the deployment of I PTV services Figure shows a high-level logical view of the scope of the OI PF I PTV solution The Open I PTV Forum has developed an end-to-end solution to allow an y consumer enddevice, com pliant to the Open I PTV Forum specifications, to access enriched and personalised I PTV services either in a m anaged or a non-m anaged network To that end, the Open I PTV Forum focuses on standardising the user-to-network interface (UN I ) both for a m anaged and a non-m anaged network, as depicted in Figure M an ag ed N e t w o rk OIPF Com m on rd P a rt y C o n te n t P ro v i d e r

interchangeabl y to refer to the ability to access an y service provider using an y access network provider without an y quality of service guarantees Managed network I PTV services are provided with QoS guarantees, for exam ple within a triple-play walled garden Open I nternet I PTV services are accessed via the I nternet, without QoS guarantees, for example via a portal In both cases, I PTV services are accessed via a service platform that provides supporting facilities for multiple service providers Third-party content providers suppl y media assets that are delivered within the I PTV

as the residential network) is as shown in Figure B and composed of functional entities, with well-defined interfaces between them , and where each functional entity includes a num ber of functions As shown in Figure B.2, the entire collection of these functional entities is called the I PTV terminal function (I TF) The residential network architecture is designed to: • • support m ultiple deployment scenarios; allow non-I PTV applications to co-exist with I PTV services, but be able to execute independentl y from the I PTV service The architecture chosen to com pl y with the above is depicted in Figure B below There are two main interface groups between the Residential N etwork and the Provider(s) Network dom ain: the H N I -I NI and the H NI -AMNI The m apping between these key functional groupings and UN I reference points is depicted in Figure B Note also that while not shown explicitl y in Figure B 2, all com munications are mediated by the WAN gateway IEC Fi g u re B – Resi d en ti al n etwork arch i tectu re I EC 62766-1 : 201 © I EC 201 B B F u n cti o n a l – 33 – e n ti ti e s G e n e l Below is a brief description of the functional entities in the residential network B 2 Open I P T V t e rm i n a l fu n c t i o n a l en ti ty (O I TF ) The OI TF includes the functionality required to access I PTV service for both the unm anaged and the m anaged network m odels through the HN I -I NI and HN I -I GI interfaces • • To access the I PTV services using the unmanaged model, the OI TF only needs to use the HN I -I NI interface Thus, the m inim um set of functional entities needed to access unm anaged I PTV services are the OI TF and the WAN gateway To access I PTV service using the managed network m odel, the OI TF needs to use both the H NI -I N I and the H NI -I GI interfaces Thus, the minimum set of functional entities needed to access the managed I PTV services are the OI TF, the I G and the WAN gateway (as it provides the ph ysical connection between the residential network and the WAN) The HN I -I GI interface requires special protection, as it carries credentials/secrets The OI TF has its own direct user interaction (e.g , rem ote control, keyboard) and audio/video rendering and, optionall y, grabbing functionalities (e g display, speakers, cameras, microphones) or can be directl y connected with other audio/video rendering/grabbing devices without passing through hom e network communication All residential network deploym ents will have at least one instance of the OI TF The OI TF may include functions to allow Open I PTV Forum defined services to be accessed on DLNA devices [24] B 3 I M S g a t e w a y fu n c t i o n a l e n ti t y ( I G ) The I G includes the necessary functionality to allow an OI TF device to access m anaged network services, based on an I MS core network, through the HN I -I GI interface The I G provides an I PTV end user with access to m anaged network I PTV services and to blended person-to-person comm unication services such as chat, messaging, presence, etc Support for unsolicited notification is also included for such services as presence, caller I D, etc The I G is able to offer its functionality to the AG via the H NI -AGI interface Support for new or enhanced applications can be realized by a firm ware upgrade to the I G without an y impacts on the OI TF functionality In a device that implem ents both the OI TF and I G , the use of the HN I -I GI interface is optional B Ap p l i c a t i o n g a t e w a y fu n c t i o n a l e n t i t y ( AG ) The application gateway (AG) is an optional gateway function that incorporates a procedural language-based application execution environm ent where applications can be remotel y downloaded for execution This functionality is required by certain service providers that wish to have generic procedural language-based applications related or unrelated to I PTV services downloaded for execution in the hom e environm ent Exam ples of applications related to I PTV services include: – an EPG generating a remote UI ; – proxying for signaling protocols when not involving SI P; and when client and server are not in the sam e I P dom ain: – 34 – I EC 62766-1 : 201 © I EC 201 – support for proprietary or non-standard content download protocols (where the AG has A/V content storage capability); – insertion of personalized advertisements in the media stream ; and – full blended person-to-person communication services (e g , videoconference using a TV set as a display) An exam ple of an application unrelated to I PTV services is one that collects alarms from hom e devices To interface to the AG, an OI TF uses the H NI -I NI * interface The HN I -I NI * is a subset of the reference points in the HN I -I NI interface in addition to support for discovery of an AG by an OI TF When present, the AG, via an application running in the executable application environm ent, can perform an y of the following functionalities: • • Manipulate m edia streams Note that for protected content, this is onl y addressed when the AG and the CSPG are combined in the sam e device and that the I EC 62766 series does not define the routing of media content (for the purposes of m edia control) via an AG that is not also a CSPG Filter content guide (CG) data I nsertion of its own CG data Note that in the release solution, this is onl y addressed where the resulting content guide is output from the AG to the OI TF in the form of a rem ote UI The release solution does not define how an AG may output CG data in broadcast content guide (BCG) form at to an OI TF, or how an OI TF m ay discover that BCG form at inform ation is available from an AG – Support proprietary applications through a remote user interface (RUI ) – Support for proprietary or non-standard content download protocols – Support advanced blended communication services When the AG is deployed in a device with local graphics rendering (e g com bined with an OI TF), applications running in the PAE can offer a wide range of applications and services directl y using that local graphics rendering system without using a remote UI The AG is able to m ake use of the services of the I G via the HN I -AGI interface This interface is not defined in the release solution H owever, where an AG and an OI TF are combined in the sam e device, the device m ay use the H NI -I GI interface for both DAE and PAE applications B.3.2.5 Content and service protection (CSP) gateway functional entity (CSPG) The CSP gateway (CSPG) is an optional gateway functional entity that provides a conversion from a content and service protection solution in the network to a secure authenticated channel between the CSPG and the OI TF B.3.2.6 WAN gateway functional entity (WG) The WAN gateway function supports the ph ysical connection between the residential LAN and the access network WAN A WAN gateway functional entity will exist in all deployments although not all its functions will be required in all cases B.4 B.4.1 Residential network functional entities General The following is a more detailed description of the various functional entities identified above I EC 62766-1 : 201 © I EC 201 – 35 – For ease of understanding of the detailed functional description of the residential network, this document uses a stepwi se buildup of the residential network functional entities com prising of the following steps: • • • OI TF and WAN gateway (WG); OI TF, WG and I G; OI TF, WG, I G and the optional functional entities AG and CSPG This buildup of functions does not impl y that these combinations of functions are the onl y deploym ent options possible Each of the OI TF, I G, AG, CSPG and WAN gateway functional entities may be deployed as separate ph ysical devices in the residential network or in com binations or m ay not be deployed at all in the case of the optional entities AG and CSPG B Open I P T V t e rm i n a

the downloaded applications is within the scope of the Forum The DAE can also query, internall y to the OI TF, the Metadata-based content guide client in order to extract an y data it may contain The downloaded applications that run in the DAE are considered to be service provider specific and therefore will not be defined by the Forum ’s specifications : client for m etadata-based content guides
