Re: Ultra HD at CES

said by JPL:

The pipe going from Verizon to your house isn't the only one that needs to be expanded is my point. And the reason I made that point is because I kept reading postings on here that made the claim that if these service providers just upped their bandwidth, we could easily go 4k. No, we can't. Because the link from service provider to your house is only one link in the chain. And Rainbow isn't the only one doing that. They just seem to be the one that fosters the greatest number of complaints.

The link from the program provider to the service provider is relatively easy to upgrade; they do that all the time to meet the needs of different program providers. Some providers use satellite backhaul, others use fiber links. In either case, the TV service provider can, upgrade its gear and set up the link relatively easily.

Yes, however program providers are compressing their signals so they can save money on the uplink transmissions -- see Comcast / NBC Universal merger -- Comcast now compresses their channels so they can save on the uplink and the quality has gone to crap.

How would that affect a fiber link?

It wouldn't, but not everything is sent to Vz via Fiber.

Chances are, if they really wanted to offer a 4K channel, they'd use a fiber link to ingest it.

But I believe the point being made is that several channels on a few providers aren't even really being sent up to what we would consider HD quality, so which provider would step up and provide a 4k signal?

Pretty much any of today's major players could provide you with a 4K feed tomorrow if they so wished.

You don't get uncompressed 1080i or 720p today, you wont tomorrow. Bandwidth is not an issue codecs are that allow for clean & clear picture transmission to the STB from provider to customer.

MPEG-2 wont cut it, MPEG-4 could carry 4K today if it so wanted to.

There is no installed base to compel them to deliver 4K broadcasts, regardless of content. The same was true for HD till it reached critical mass, 3D at the current adoption rate will hit critical mass in about 15 years....if ever.....currently the only way it will reach mass is if its built in to TV's by default.
