Directv 4K quality

It is VOD now but it is a step above 1080 picture

Without seeing it (in person) for yourself -there is no real way to "SEE" the difference in any internet forum.

 

definitely you didn't read enough if did that at all

a lot of people expressed they experience with DTV 4k clips,events, VODs, etc

 

Is it any better than watching a 4-K TV - UP-Scaling from a 1080 feed ?

 

Downloading 4k isn't for everyone. Data caps, internet speeds all play into it. I really don't see why all the hoopla about 4k until its being broadcast live. A tip from Solid Signal a 45-minute sample movie took almost two hours on a 60 megabit line in the lab and the file size was a whopping 50 GB. This isn't even a full length movie.

 

So is the upscaled D* content, I think.

Right, we do see a lot of negative comments from folks who don't have 4K sets. You really have to have one to appreciate the PQ.

Did you mean 1080p or 1080i, makes a big difference.

Directv is using a 30 Mbps bit rate for their 4K, which equates to 13.5 GB per hour. That 45 minute sample would have to have been encoded at 150 Mbps for 45 minutes to require 50 GB - that's higher than 4K Blu Ray bit rate so I think they probably had a math error somewhere in their calculations.

 

There is a notable quality improvement from the videos I have watched. They all seem to be 70mm IMAX films that were transferred at 4K.

 

They must have something crossed then. I looked at their numbers and said no way I could do that. I watch MLBTV games also, this year we have the option of following just a single team which is very nice. Thank goodness for the class action law suit.

 

I streamed some 4k off Amazon and it may have been a bit better than upscaled 1080 but didn't blow me away. I just wanted to check to see what it looked like and how much cap it would use. Was about 1.7 gigs for 20 minutes.

 

Streaming movies or VOD will always be lower bit rate than streaming live TV. Encoders are simply a lot more efficient when they can 'take their time' to compress, instead of having to do it in real time.

And as with anything, there are varying levels of quality. Just as with HD, there will be different levels of 4K quality. I'm sure at first providers will be delivering pretty high quality 4K, just like they did at first with HD. If 4K is successful and providers are trying to figure out how to deliver 100 4K channels, quality will inevitably suffer. If there are a lot fewer, Directv will have so much excess bandwidth they'd be able to deliver some high quality 4K indeed

 

What about upconverting current HD to 4k? Is their that much of a difference?

 

I definitely notice a difference from watching some VOD stuff as well as channel 104. Much better detail and less macroblocking.

I have always been somewhat underwhelmed by Amazon's 4K streaming but a lot of it boils down to the source. That said, I recently revisited an episode of Better Call Saul that I purchased through them and the quality seemed improved since last time I watched. In general I have noticed that Netflix's quality seems better but that is hit or miss because they have stuff like Groundhog's Day which is full of grain and looks flat due to the old and probably not very high quality film stock. (Or a poor transfer.)

 

While true it's important to note non of DIRECTVs 4K comes over the Internet. All their Video On Demand is pushed via sat. So no data caps to worry about.

 

To me yes. Easy to tell.

 

Oh wow, I didn't realize that it actually downloaded it via satellite, thanks! I just queued up a couple 4K VODs and looking at my router traffic it isn't pulling anything through my connection. No wonder it is so slow and this whole time I thought it was barely using my 240mbps connection.

Lear something new every day!

 

What is so slow ? The Internet or the VOD feed ?
What carrier do you have for 240 MPBS ??
