Intermittent black screen - DirecTV

#1
Several days ago I started getting about 3 seconds of picture and 1 second of black screen in a cycle. The black screen got longer and in about 5 minutes everything froze. If I turned the tv off, I could start the cycle over. I have refreshed the DVR and reprogrammed the satellite multiple times. Very occasionally I will get a sustained picture for an hour or so. My question is this: Is this a satellite problem or my equipment problem... ie... HDMI cable or satellie?
Thank you in advance.
