Will this (or something like this?) work?
cat $vid > /tmp/out1 ; sleep 10; cat $vid > /tmp/out2
diff /tmp/out1 /tmp/out2 1>/dev/null 2>/dev/null && echo "STB is powered off?"
That is, out1, out2 will not differ if the STB is dead as it is
grabbing blank frames.( and blank grab files /hopefully/ are exactly
out1,out2 will be differing it STB is sending stuff over to grab.
That being said, I am miles away from my machine to test.
