scope:

The present document is an updated release of TS 102 034 "Transport of MPEG-2 TS Based DVB Services over IP Based Networks"; it is referred to as DVB-IPTV phase 1.4 and provides extensions to the first set of standardized specifications published by DVB for deployments of DVB services over bi-directional IP networks.

Specifically, it adds support for the following new features:

• Support for Remote Management and Firmware Update Services (RMS-FUS) for managed and unmanaged populations of DVB-IPTV Delivery Network Gateways (DNGs) and Home Network End Devices (HNEDs).

• Regionalisation metadata to enable a HNED to acquire the region in which it is located, from and for a service provider. This is used for the signalling of availability of DVB-IPTV services based on regions.

• Support for Content Download Services (CDSs) for user (pull download) or service provider (push download) initiated download of content items to the HNED.

• Optional retransmission mechanism to provide for protection against packet loss of RTP streams.

As in previous releases of TS 102 034, the DVB-IPTV phase 1.4 work is limited to DVB services [1] encapsulated in MPEG-2 TS [52] covering Live Media Broadcast services (i.e. TV or radio styles), Media Broadcast with Trick Modes and Content on Demand services (CoD). In addition CDSs are supported. These specifications define the mechanisms required in order for a consumer to be able to buy a standard DVB Home Network End Device, take it home, plug it into an IP network, choose and consume DVB services available over the IP network. Clause 4 describes the architectural framework defined for this set of specifications and introduces a Home Network reference model. The contents of the remaining clauses are described below.
