Perhaps. I think the guys at one of the other PVR software places
recently blogged about an 11 tuner system using a combination of PVR-500
(2 tuner / PCI) and USB tuners. With hardware encoding, you could
easily go above 4 tuners per backend. I think your limitations come
more in the bandwidth writing to disk and serving the content out.
You can easily address the disk writing limitations by moving away from
local storage on the backend to something more SAN like using
I think you can also address the serving/network bandwidth by using
non-backend NFS servers to share the aforementioned storage. While the
frontend does need to talk to the backend systems for things like
scheduling, etc., if it has local access to the files via NFS shares, it
will use that for distribution leaving the backends alone.
I imagine part of the challenge of using Myth for this type of
environment will boil down more to the questions of security and how do
you prevent those 300 users from disabling other users scheduling rules,
deleting content, or otherwise mucking about. The system isn't designed
for disparate users but more of a common househould...
Something to think about.
