ETSI TS 102 542-2 is designed as a companion document to help implement the DVB-IPTV Phase 1 specification ETSI TS 102 034 [1], which is referred to as the Handbook.

The present document deals with Broadband Content Guide (BCG) and Content on Demand. It presents the ways to discover BCG and Content on Demand, and how to connect to them. The present document is organized in separate sections in the order of the boot-up sequence of the HNED rather than in the same section structure as the Handbook.

Each clause deals with a specific aspect of the DVB-IPTV technology, and offers explanations and examples not found in the Handbook. Additionally, it provides guidelines to implement the Broadband Content Guide (BCG) specification [3].

Since version 6 the DVB IPTV Handbook [1] also supports the usage of IPv6 addresses and accompanying methods (e.g. for address assigning and multicast support). For the sake of convenience, some examples presented in the present document still make use of IPv4 addresses although IPv6 addresses could also be used. Due to the fact that the IPTV Handbook supports IPv4 and Iv6 in parallel, there is no example which could only work in either an IPv4 or an IPv6 network.
