21、d This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The present document describes the main type of IMS based IPTV Customer Devices that take part in Customer
22、 Premises Network in terms of general architecture and in terms of reference points with the NGN and CNG. ETSI ETSI TS 185 009 V2.2.1 (2009-05) 6 1 Scope The present document defines the stage 2 Customer Network Devices for IPTV services (IPTV-CND) specifications. It is therefore addressing the over
23、all architecture of the customer network device (CND) enabling the IPTV service consumption. The architectural definition is covering both transport and service layer related functionalities. The reference points between the CND and the Customer Network Gateway (CNG) are also part of the specificati
24、ons. The 2 solutions elaborated specified in TS 182 027 2 and TS 182 028 4 are IMS based IPTV and IPTV Dedicated Subsystem solutions but only the IMS based IPTV solution is considered in the present document. 2 References References are either specific (identified by date of publication and/or editi
25、on number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is accepted that it will be possible to use all future changes of the r

36、 they could be also Consumer Electronics equipment and other devices which may have nothing to do with these premium services (e.g. services performing a content sharing within a CPN, typically between a PC and a music system, through the CNG). Customer Network Gateway (CNG): gateway between the Cus
37、tomer Premises Network (CPN) and the Access Network able to perform networking functions from physical connection to bridging and routing capabilities, but also possibly implementing functions related to the service support Customer Premises Network (CPN): in-house network composed by customer netwo
38、rk gateway, customer network devices, network segments (physical wired or wireless connections between customer network elements), network adapters (performing a L1/L2 conversion between different network segments) and nodes (network adapters with L3 routing capabilities) IPTV services Customer Netw
39、ork Device (IPTV-CND): physical device enabling consumption of IPTV service(s) NOTE: IPTV-CNDs are dedicated to the TV like audio-visual services such as live TV or On demand. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ACF Access Configuration Func
