I bought a Daewoo box with a Top up Tv slot, and it's been just about
perfect. Mind you I did have a new antenna fitted, as I was told 90% of
the problems people have are in reality antenna faults.
Told by the people who sell these shit digiboxes, I presume.
The box gets a garbage signal.... it puts garbage out !
Obviously if the signal input breaks up, the image output will breakup,
but it is not acceptable for the box to crash or reboot under any
circumstances short of pouring a bucket of water on it.
In an ideal world, the MPEG decompression implementation will have been
properly fuzz-tested to make sure that it can cope with being fed garbage
(i.e. a burst of RF noise) without crashing.
However, back in the real world, with limited time available for R&D, and
limited margins, this testing and any remediation will be similarly
limited. Rebooting is probably the least-bad option for many boxes, and
will be controlled by a watchdog timer that detects when the box appears
to have hung.
