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 1.5 and provides extensions to the 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:

• Delivery of System Renewability Messages (SRM) over IP networks

• Optional server-based fast channel change mechanism to reduce the Live Media Broadcast service switching response time

• Optional companion stream fast channel change mechanism to reduce the Live Media Broadcast service switching response time

• DVB Frame compatible plano stereoscopic 3DTV

As in previous releases of the present document, the DVB-IPTV phase 1.5 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, Content on Demand services (CoD) and Content Download Services (CDS). These specifications define the mechanisms required in order for a consumer to be able to buy a standard DVB Home Network End Device (HNED), take it home, plug it into an IP network, choose and consume DVB services available over the IP network.

The interface to the HNED defined as IPI-1 in clause 4 represents the end-terminal interface for a DVB-IPTV service. This IPTV ecosystem can be extended with a home network content sharing model as defined in the DVB Home Network specification (DVB-HN) TS 102 905 [114], which uses the DLNA Guidelines [i.4] as its foundation.

Clause 4 describes the architectural framework defined for the present document and introduces a Home Network reference model. The content of the remaining clauses are described below.
