A Cable Show IP Video Descrambler5/11/2010 1:39 PM Eastern
One of the stronger undercurrents at this week's Cable Show will be
those two awkward letters, "IP," shadowing every move of the core
From the places where video gushes in to cable headends, to the
gadgets and screens hanging off the ends of the plant, make way.
Internet Protocol, or IP, is somewhere very nearby.
Let's start with the places where video gushes in to the headend.
From geosynchronous orbit, into the IRD (integrated receiver/decoder)
of the satellite dish, right? Yes, but in the new lingo, video content
comes from an off-lane of a fiber backbone, called a Content Delivery
Network. CDN. Know it.
Then there's the stuff hanging off the ends of the plant. Televisions, telephones, and computers, right? Video, voice, data.
Yes, but it's that data passageway, constructed in the late 1990s,
that's at the helm of IP. It was conceived as a way to blast data at
high speeds into a cable modem connected to a computer. We call it
Broadband begat the Baby Huey that is - well -- IP. And the Baby
Huey that is IP is thirsty. Screen upon screen has Wi-Fi or Ethernet
spigots, and wants a connection. Wi-Fi and Ethernet are the wireless
and wired ambassadors of IP, respectively, iPads, smart phones,
netbooks, laptops, e-readers -- they live when connected to IP.
In the middle, everything else. Tons of it. The navigational system.
The hooks into billing systems and core video controllers. "Conditional
access," which in the IP world cedes to digital rights management, or
"DRM." Where to make room for "transcoding," of incoming video, into
the many different resolutions and formats that are thirsting for it on
the receive end.
Architecture. Also big. Going to video over IP means sending video
through the CMTS (Cable Modem Termination System), instead of through
the digital video side of the house. In familial terms, it's the uncle
giving the family jewels to the nephew. In technical terms, it's a big
Gateways, that's something we'll be hearing a lot about, with IP
ascending. Video gateways, home networking gateways, data gateways. Is
it a cable modem tricked out for video, or a digital set-top, tricked
out for IP? (Magic 8-ball says: Ask again later.)
Why all this IP hullaballoo? Chief among the reasons to belly up to
IP is its speed, in making new stuff and getting it out there. Open up
the interfaces, slide a web-based magic carpet onto the front end, test
it, get it out there - weeks. Not months.
There's also the matter of money. Especially the huge piles of cash
directed at developing and honing the stuff of IP. Tonnage of it,
compared to traditional digital video.
When it comes to IP, it's probably best to just go with the flow --
which is yet another example of the linguistic difficulties of "IP."
(Just like "it seems like IP everywhere." Say it out loud and you'll
see what we mean).
