[mythtv] IPTV project - 'officially' starting

[Jun Yu]

I am interested in the idea or GPL iptv solution but not quite sure about
what you are referring to here. Are you talking about to use backend as
server and stream the video to the frontend which is pretty much what mythtv
does today? Simply enable UDP multicast isn't going anyway unless you have
router supports multicast to MANY users with MANY video sources. You don't
need multicast to support 2 or 3, even 4 or 5 frontends which is a lot
comparing to what most of us have at home. Also, with mutilcast, the
frontend would have to buffer the video so it can moving back which make it
a recorder also.
I am in the process of building my home entertainment system with one
backend with 4 tunners and 4 frontends for each TV.
My idea of IPTV infrastructure would be like this: a server/backend shoot
out video programming on different channels (AKA multicast IPs), when client
chose a channel, it register corrordinate multicast IP with the route which
will then distributing the stream down. But that is hardly needed by any
family, I would think.
Paul, It is not my intention to shot anyone rather than sharing my 2 cents.
