SHV Video, Now That's Bandwidth

September 17th, 2008 by · 1 Comment

Over on Contentinople is an article on SHV, or Super Hi Vision, which is seen as a successor to HD.  What is it?  Think resolution of 33M pixels (7680 X 4320) and 22 channels of sound.  Think 24Gb/s uncompressed, maybe 1Gb/s compressed.  One hour of SHV video would bust that Comcast usage limit.  Of course, we're just barely seeing HD video go anywhere now let alone via the internet, so this is far far away. 

Just think of the bandwidth SHV would require though.  Think of the aggregation networks you'd need to supply SHV video on-demand to a neighborhood for this sort of thing.  Exaflood doesn't even begin to describe it. Then there's this quote:

Uptake of 3D and even super high-resolution HD will depend on how technology "catches the users' imagination," [Zubrzycki]

Well, I have to disagree there. Uptake of these technologies will depend much more on the ability of networks to deliver 100 times (or more) what they do now but for the same price something that will take many breakthroughs.  Catching the user's imagination is much easier than convincing his non-infinite wallet to open that much wider.  But that said, I know some fiber-based carriers that would love to take on the challenge...

Yeah, I know, it's more dream than anything else right now.  But with the financial markets in the state they are, sometimes dreams can help pass the time.

    You’re onto something here, Rob, but probably not as one would notice by reading the following:

    “Well, I have to disagree there. Uptake of these technologies will depend much more on the ability of networks to deliver 100 times (or more) what they do now but for the same price something that will take many breakthroughs.”

    Source-sink relathionships and where sources are sited with respect to the sink, are all important here. Of course, I agree with your assessment above if sourcing and delivery were made possible only over the larger WAN of today, and through the use of protocols that are used to optimize delivery over the Internet. However, it’s not difficult to conceive a scenario where a closed communications network, say a greenfield network where the also possesses caching capabilities, couldn’t deliver such payloads over an infrastructure using WDM, or even a second strand that availed itself of “wide open glass” properties — or even coax in situations that were less demanding. And with time, as we’ve seen in just about every other futuristic type of possibility, the world of global inter-networking qill eventually catch up.

    Incidentally, this is the same migratory pattern local area network protocols took, first in-building, then over the access network, then the metro, and finally the WAN . Hm…
