| Trunkin said: The most expensive 4K displays at this Bestbuy each had their own unique demo reel, while the cheaper 4K sets had ads for Netflix, Hulu, etc. 1080p sets were playing seemingly random footage. One was what looked like a DVD of TDKR, and some of the others had TV ads running, so it could have been cable. Walmarts in my area tend to have the same footage showing on all their TVs usually with one special exception, so you may have hit the nail on the head, there. I didn't realise cable was still capped at 1080i. 7-8mbits? Wtf? Does that include channels like HBO and Starz? Bummer, if so. I guess this explains why the Walking Dead looks and sounds so much better on Netflix than it does on TV. |
Afaik hdtv broadcasts are still in 720p or 1080i. My cable box doesn't have a 1080p option, 1080i is the highest. At the start (2006) we got the full 15mbps channels, yet after they started adding more HD channels they reduced the bandwith to half to squeeze more in. It's something like this: Channels are received at 21mbps, it used to be 1 HD channel packed with 1 SD channel, now 3 HD channels are packed together and SD channels have been compressed even further. There's only a maximum amount of total bandwidth, more channels = lower quality.
If you know how big the HDD is in your pvr it's not that difficult to caclulate the average bandwidth. The more fits on, the lower the bandwidth gets.
And yeah HD cable looks like a joke during fast action scenes. Analog tv looked better during fast action. However analog has been axed completely to make room for more 'HD' channels. (You need a digital adapter now for horrible quality SD channels)
