XMLTVFormat
The Triax preferred format is the open XMLTVFormat. This format provides a well-defined structure for the EPG data
that can be used in a variety of devices. It should be noted, however, that the TDX, and thus also the EPG Server is
providing the data in UTC time rather than local time, and the application reading the XMLTVFormat must therefore
correct for the local timezone and DST before presenting it to the user.
This picture demonstrates how the XMLTVFormat may be presented after a timezone correction and after the DVB
Triplets have been translated into the actual service names.

Information necessary for the Middleware Server
The IPTV EPG Server is designed to provide EPG data to an IPTV Hospitality TV or Set Top Box. In these setups, the
Middleware Server controls the channel mapping for the TVs, and the only channel information the IPTV EPG Server
can extract from the Barker stream, is the Original Network ID (ONID), the Transport Stream ID (TSID) and the Service
ID (SID). All this means that the Middleware Server must request the EPG data from the IPTV EPG server, using the
ONID, TSID and SID.
