Is your black box networked?
If so, there's different clients to log-on, rsh and telnet to it.
Moreover, you can control the "remote control"
interface via a java clients or something custom that can be made in rev
(which i dont want to go into
since the java client does it all already). With this interface (in this
case the Gemini Manager for dreambox)
you can framegrab, import recorded movies, schedule recordings, etc...
Sounds like what you need...
The key would be to look for such a client for your blackbox - hopefully
there is one for Mac or unix that can be ported to
The dreambox can also emulate different decoders and gets frequent "system
updates" via the
net (including codecs, keys, sat-directories, EPGs, etc) which is why it's
so interesting... Im not sure it's legal in the
states though - but it's easy to find in europe... www.dreamboxworld.com
has most the info and links you'll need.
Just throwing some magic ideas that work well in this category for me and
a few friends who have dreamboxes.
What's the feed name?
