Why are TV shows still sent via satellite?

This won’t end well.

Hail Ants, I know what you mean. It’s been a long frustrating day and I’m getting crabby. No need to argue the matter.

Maya runs on Windows, OSX and Linux. From what I’ve read, they have a mixture. When they were animating and rendering on SGIs, they were scanning all the artwork to Adobe Illustrator files with a Windows-only product, CorelDraw. They probably use Macs for artist workstations and PCs running Windows 7 or some variety of Linux for rendering. That’s how I’d do it - put the pretty and more malware-resistant interface in front of the artists, and put the better bang-for-the-buck systems in the back churning out frames.

Once the jump to the backbone is installed, there isn’t much to maintain. The backbone is going to be maintained because well, it’s the backbone. Every major city in the US has at least one Tier 1 backbone connection.

You’re suggesting a realtime uncompressed feed over the internet is somehow slower than someone driving to some facility and having the information beamed some 330,000 miles into space and back instead of the broadcast dumping onto the backbone at the headpoint and arriving at its destination milliseconds later?

No, but I am claiming these delays are measured in tens milliseconds. Not the thousands of milliseconds in a satellite uplink delay. Surely we can agree that tens of milliseconds is less than thousands of milliseconds, thus ensuring IP is in fact “faster” than satellite. I don’t see how instant quality check changes the laws of physics, to wit, the speed of light.

Also, just as an aside, can satellite handle an uncompressed 1080 feed with room to spare?

Oh, I see…it’s just a small problem then. I’ll just call Google and ask them to drop a line over to the house then.

You’ve avoided dealing with the issue of what this would cost. Again, they’d have to pay for this 24/7 service every month. Assuming the contract they would have to get to get that “last mile” service that can stream the same speed as the backbone, is anything like the one I have to deal with as a consumer, they would be locked into service for a year. For a program that is only in production 14 weeks out of the year.

Sorry, but appear to be deliberately confusing the meaning of “speed” in this context. How fast the first bit gets there is not particularly important. How fast the rest of the bits get there is.

I’m talking about two transportation systems. One has an inherent delay of roughly 3 seconds compared to the other, but vastly greater reliability and bandwidth.

To abuse your comparison, I’m not talking about the speed of light, but the quantity of light.

Please, you have GOT to be kidding! Seriously!

How do you think every single HD TV program you’ve ever seen was delivered to you? Fiber is the exception, not the rule.

As for bandwidth, a C or Ku satellite has from 24 or more transponders. A typical, though older sat like AMC-3 has 24 C and 24 Ku transponders - devices that just re-transmit the signal they receive on a particular frequency band. This chart will show you how many different channels are on each satellite - notehow many standard definition MPEG4 channels are on a single transponder. Note also how many of them are labeled “HD”.

The bandwidth needs of the different broadcasters vary. Each engineer selects the parameters for symbol rate, PIDs, etc. But in general, you can fit 5 HD signals on a single transponder, at a very low level of compression. Uploading a program like South Park, they just need a small amount of time on a portion of a transponder. They buy just that block of time, or they use one of the transponders that Comedy Central has already leased.

Pop around that site I linked, and move from satellite to satellite. You will see every single TV channel you have ever heard of and hundreds you have never heard of. And all those ones labeled “FEED” are feeds of network programming, sporting events, interviews, syndicated programs, corporate television, music, nearly every piece of media you have ever consumed.
