890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.6.1 Service reporting capture | Service reporting information captured by the Multicast gateway is supplied to the Service reporting capture function via reference point RS. The reports may include metrics and other key indicators describing the performance of the service (e.g. cache hit ratio, viewership). The metrics depend on which channels are re... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.6.2 Network control | This function is responsible for controlling, configuring and provisioning Network resources. This includes the resources for multicast transmission (over reference point M) and well as those for unicast operation (over reference points U, A, A′, A″ and B). In systems with centralized co-ordination, the Network control... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.7 Content Provider control | This function uses the control interface CCP provided by the Network control function to provision information about services that can be made available over the multicast delivery path M. A single Content Provider control function may be interacting with multiple Network control functions, each one of the latter opera... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8 Content playback | |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8.0 Introduction | 5.3. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 8.0 Introduction | This is the entity managing the request, reception, decryption and presentation of content. It only supports unicast delivery via reference point L. Playback behaviour is agnostic to the delivery path traversed by the content. The Content playback function may be located separately from the Multicast gateway on an end ... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8.1 Content unpackaging | The Content unpackaging subfunction is responsible for extracting elementary stream data from retrieved transport objects and presenting it to the Content decryption and Content decoding subfunctions. For example, with ISO Base Media File Format segments this involves extracting the appropriate media data box(es), whil... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8.2 Content decryption | If a Digital Rights Management system is in operation, the Content decryption subfunction is responsible for obtaining appropriate decryption keys from the DRM licence management function and for decrypting any encrypted elementary streams. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8.3 Content decoding | The Content decoding subfunction is responsible for parsing and interpreting the contents of elementary media streams, allowing them to be rendered for playback on, for example, a screen or loudspeakers. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.8.4 Playback metrics reporting | The Playback metrics reporting subfunction reports information relating to the behaviour and quality of experience of content playback to the Content Provider metrics reporting capture function via reference point RPM. The metrics may include (but are not limited to) details of HTTP request/response transactions, initi... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.9 Multicast rendezvous service | The Multicast rendezvous service maintains records of managed Multicast gateway instances, including their current status, and records of current multicast sessions, including their status. The Network control function is responsible for supplying all of this information to the Multicast rendezvous service, but the mea... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.10 DRM licence management | This optional entity is responsible for core content protection services, providing appropriate encryption keys to be used by the Content encryption function, and supplying licences to the Content decryption subfunction to enable the Content playback function to decrypt encrypted content. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.11 Application | The Application is responsible for controlling the Content playback function. Examples include an embedded control application on an integrated television set or set-top box ("EPG application") or a third-party application contributed by a Content Provider. The interface the Application function uses to control the Con... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 5.3.12 Service directory | The Application may use a private Service directory in order to locate available linear services. The Service directory function may be configured by the Content provider control function. Because the Service directory function is application-specific it is outside the scope of the present document. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 6 Deployment models | 6.0 Introduction The reference architecture described in clause 5 is intended to support the deployment models described in this clause. |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 6.1 Multicast gateway deployed in network edge device | Figure 6.1-1 The terminal device does not support reception of IP multicast from the home network. It includes the Content playback function, and loads an Application to control linear playback. The Multicast gateway is deployed in a network edge device upstream of the terminal device and provides multicast-to-unicast ... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 6.2 Multicast gateway deployed in home gateway device | Figure 6.2-1 The Multicast gateway is deployed in a home gateway device, such as a router (typically supplied by the Internet Service Provider) and provides multicast-to-unicast conversion facilities for multiple terminal devices in the same home network. These terminal devices each have an instance of the Content play... |
890aa8b91864c4a2d64f76c40ff5f123 | 103 769 | 6.3 Multicast gateway deployed in terminal device | Figure 6.3-1 The terminal device supports reception of IP multicast within the home network. Each such terminal device includes both Multicast gateway and Content playback functions, and loads its own Application to control linear playback. In this deployment model, the Multicast Gateway function shall provide content ... |
