Are they going to be able to deliver 4K using MPEG4? or will it take a transition to HEVC/H.265? Any news on when we'll be seeing 4K on DirecTV?

 

HEVC/H.265 probably means new satellites, dishes/LNBs, receivers?

 

Would make sense to switch to HEVC/H.265 for bandwidth anyways...

It would not take new satelites. It would not take new dishes or lnbs.

It would take new sat boxes and of course a new tv.

But who knows.

1080 p can not offer as dramatic a difference as 4k could over 1080i.

I wouldn't be surprised if dtv doesn't offer 4k stuff within two years. But who knows.

Lol, well, there are some PPVs in 1080p. People are gonna demand 4k when they get 4k TVs.

 

H.265 = 50% less bandwidth then MPEG4 at the same bitrate. Still a lot of bandwidth for 4k.

So if they change the encoding to H.265, they wouldn't need to replace any hardware except the boxes? Didn't they have to change everything for HDTV? Although that was the Ka/Ku transition too.

Satellites dont care what is transmitted to and from, same thing with dishes and LNBs.  Remember when HD first came out it was in MPEG2 on 101.

I think HEVC is going to have to get out there and into use, and it'll be good for everyone.

H.265 is far from ready for prime time..H.264 provides superior results, from what i've seen to date. Was kind of bummed about it, actually. H.264 has been around a long time though..not sure if or when 4k will be available via sat. If wanting UHD/4K now, Sony will stream if willing to join their service (aka proprietary), and get the right equipment.

How does that work? I thought bitrate and bandwidth were inextricably tied together.

As was said earlier, we haven't even completed the transition from SD to HD yet. I think the current state of 3D foreshadows the uphill climb that 4K has ahead of it. There is a lot of support for it among the groups of people who take the time to join an internet forum dedicated to a satellite TV service or to AV equipment discussions, but you have to keep in mind that we here or the folks at somewhere like AVS are a very very small minority when it comes to the customer base of DirecTV. There aren't a lot of 4K TVs out there, the general public has no idea what it is, plus there's a lack of content even to fill a channel. Plus, bandwidth is an issue not only on the service provider (DirecTV) side, but on the distribution side. There's not an unlimited amount of satellite space for channels to send their signals to cable/satellite companies and moving to 4K would put a strain on that to be sure. I'm sure many content providers are still using older MPEG-2 systems to distribute.

 

I see it, for a good long time, being a niche that is served by a couple of PPV channels and perhaps one or two linear movie or event channels. If you're expecting every day channels like Discovery or USA, or heck even the normal HBO feed to switch to 4K, you may be waiting a while. It wouldn't require new dishes, LNBs, or satellites in space, but it would certainly need new receivers and TVs.

 

 

How does that work? I thought bitrate and bandwidth were inextricably tied together. 

 

I think maybe he misspoke. By "bitrate" maybe he meant resolution/picture quality. Bitrate and bandwidth are exactly the same thing.

If you're missing a post it's because of me.  As has been posted many, many times, discuss the topic and not each other.

 

Take the personal comments to PM or let it go but STOP taking jabs at each other here, or any thread for that matter.
