Re: Use of XML for MPEG Network config

[Richard Lhermitte <richard.lhermitte@thales-bm.com>]

If it's just mapping IP addresses to PIDs, DVB has defined a specific table: INT
(IP Notification Table).
But this table does not inform about service types, service description and
services schedule, but it could be possible to add some specific descriptors to
this tables to give additional information about the IP stream contents. It
depends on the information you would like to transmit in this ?XML? description.
