1080i on HD Cable Box but a 1080p HD TV...still 1080p?

I just bought a 46" 1080p HD TV, and it looks great. But the standard lamp on my HD cable box DVR only say 1080i. Does this mean the blind is broadcast in 1080p or 1080i? Which one overrides?


Answers:    I belive, unfortunatly,that it is 1080i. In the world of vidio and audio a system is with the sole purpose as strong as it's weakest link. There is no channel to upgrade a picture from your DVR box to a true 1080p unless is actually store at 1080p. Hope that makes sense. Think of it similar to scaning a picture an then blowing it up. The picture can stay to a certain extent good to a certian point but regardless it is still losing some representation quality as it get larger.
Under 1080i very other row refreshes and next interlaces for a seamless picture and with 1080p every string scans/refreshes progresively for a seamless picture. It the same amount of lines but different style to display the picture: one is interlaced and the other progresive, many HD box still don't own the capability to display surrounded by 1080p.
