The last one is true :) IPTV STBs usually are very limited, I doubt that
VDR can be loaded on it. While it ideal low-cost remote frontend staff.

Yes, that's true. VLC and streamdev i had in mind but that is not tided
with VDR and could work as an proof of concept so far.

In order to interact from IPTV STBs with backend the middle-ware
required. The main role of middle-ware to reply on http requests and
provide either RTSP URL or multicast group to STB. Basically middle-ware
is a kind of web site that take in to account that STB could overlay
http page on a top of video received via multicast. In theory vdradmin
could be extended to support IPTV STBs.
