18、 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB foste
19、rs market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consort
20、ium came together in 1993 to provide global standardization, interoperability and future proof specifications. The present document is part 1 of a multi-part deliverable covering the Guidelines for the implementation of DVB-IPTV Phase 1 specifications, as identified below: Part 1: “Core IPTV Functio
21、ns“; Part 2: “Broadband Content Guide (BCG) and Content on Demand“; Part 3: “Error Recovery“; Sub-part 1: “Overview of DVB-IPTV Error Recovery“; Sub-part 2: “Application Layer - Forward Error Correction (AL-FEC)“; Sub-part 3: “Retransmission (RET)“; Part 4: “Remote Management and Firmware Update“; P

23、ing Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 102 542-1 V2.1.1 (2016-04)7 1 Scope The present document is designed as a companion document to help implement the DVB-IPTV Phase 1
24、version 6: ETSI TS 102 034 1, which is referred to as the DVB-IPTV handbook. The present document is the part 1 of the Guidelines and is focusing on the core IPTV functions. Other parts present other aspects of the DVB-IPTV technologies. The present document is organized in separate sections in the
25、order of the boot-up sequence of the HNED rather than in the same section structure as the DVB-IPTV handbook. Each clause deals with a specific aspect of the DVB-IPTV technology, and offers explanations and examples not found in the DVB-IPTV handbook. 2 References 2.1 Normative references References

39、gh the FUS and HNED configuration changes so the requirement is for the HNED to contact the RMS. This process will be described fully in the documentation specific to the RMS methods used, where the RMS is compliant with the Broadband Forum methods. This description is carried in section 3.1 of TR-0
40、69 6. The RMS can configure the entry into the FUS announcement service using the DVB extensions described in ETSI TS 102 824 3. ETSI ETSI TS 102 542-1 V2.1.1 (2016-04)15 5.3.2 Unmanaged HNEDs In the case of an unmanaged HNED one of the options for locating the FUSS should give a result in the form
41、of either a unicast or multicast URL. Figure 5.6: Options for locating the FUSS The URI provided in the FUS Stub file may be either unicast or multicast with the options below: The unicast URL may: - point directly to a file image for downloading from the FUS directly (e.g. http:/ The Multicast URL
42、will be based on the “dvb-mcast“ URI scheme as described in clause G.3 of ETSI TS 102 034 1, and may: - point directly to a file image for downloading from the FUS directly (e.g. dvb-mcast:/ - If SDP/SAP is used as the protocol may provide: square4 location of the announcement message specific to th
43、e update image available; square4 location of the entry point of the announcement message hierarchy, may be useful to point to wider populations (not completely populated ID info in FUSS); square4 location of an intermediate pointer message based on wider targeting, may be useful to point to wider p
44、opulations (not completely populated ID info in FUSS). - If DVBSTP is used the protocol may provide: square4 location of the XML description announcement message specific to the update image available. The HNED should be able to locate the firmware update using announcement description on the addres
45、ses provided. The detailed description of those operations is provided in ETSI TS 102 824 3 and the associated guidelines in ETSI TS 102 542-4 i.8.

The capability to associate a firmware update with a specific group of HNEDs can be supported at all these levels with different levels of flexibility. 5.4 Content Discovery 5.4.0 Processing steps Now that the HNEDs have their IP address and that they have performed the FUS
49、 process (including firmware update if necessary), they start looking for the SD it is perfectly possible for the HNED to just join the corresponding multicast group. 5.5.1 Content Selection in Routed Mode with Local DHCP Server The multicast join message is sent on the HN, and the gateway forwards it to the access network. Thus the Live TV stream can be received by the HNED. DNG HNED 2 HNED 1 Home Network Segment Access
