It might have been a hoax as well. If I remember it right, it was the operator's fault. From the video footage, only some words were understandable.
On the other hand, I remember watching "encoded" audio + video from a locked channel with a satellite tuner. The quality is *very* poor, but it can be understood at times.
I believe nowadays TV sets are sold with the circuitry to decode digital data (the switching to digital land infrastructure), but I don't remember if it was the case there.
