Maybe I have a warped sense of how normal people set up their
home networks but I do notice all kinds of network storage for
sale in local computer shops, and various multi-media player devices
that connect to a TV screen, network, etc.
Yes, but there's no real standard. It's mostly hodgepodge based
solutions that allow techie types to cobble together some random
collection of hardware to resolve some particular subset of problems.
What the public wants, though, is for someone to solve this problem
and build it for them.
As an example, consider that it's a lot more popular for home users
to source their DVR from their cable company than it is for them to
get a CableCARD receiver card for their PC and try to roll a MythTV
box for themselves.
I can understand why
a TiVo collects content over the air, because it has TV receivers
built into it. My PVR does much the same thing. But when it comes
to collecting content from the Internet, it seems easier to just
let the file server do that job. Or run the nice easy software on
your home PC that allows you to search the web for torrents and
just click on the ones you want to download.
Let's face it, TiVo may have a lot of mindshare in that people
constantly talk about the thing as if it was some kind of magic,
but it hardly has the same kind of market share as the iPod.
The functions of that the TiVo carries out are software and
software is rather malleable. The functions of the various devices
can be mixed and matched in various ways. We can't predict which
combos will prevail, but we can make a pretty close guess as to
the functionality of the whole system.
The magic of TiVo isn't that it records video. The magic bit is more
abstract, and it is that someone made a device that actually does what
the average consumer _wants_, rather than simply acting as a generic
You actually said it yourself above, "it just seems easier" - but then
you got sidetracked by the loveliness of your PC. The magic of a TiVo-
like device is that end users perceive it as easier. The solution that
doesn't involve them learning what torrents are, or filesharing is, or
having to figure out how to hook a computer up to a TV is, because some
TiVo-like device took it and internalized all of that and SOLVED the
problem, and solved it not only for them but a million other TV viewers
at the same time, that's the solution that's going to be truly

Cisco sells computers that look like a telephone set but have
and Ethernet jack out the back. Whether you use the Gizmoproject
software on a PC or one of these Cisco devices, you are still
making VoIP calls on a computer. The appearance of a telephone
is not terribly relevant. My mobile phone is a computer with
Python installed on it to run a Russian-English dictionary application
but it also includes a two-way radio transciever that is programmed
to talk to a local cell transciever and behave like a telephone.
But it is still a computer at heart.
The hell it is. It's still fundamentally a phone. That you can reprogram
it to do other things is technologically interesting to a small number of
geeks, but were you to ask the average person "what is this," they'd still
see it as a phone, and see its primary job as making phone calls.
Further, that does not even begin to argue against what I was saying,
which is that most people are NOT making phone calls using VoIP from

Yes. There's a certain amount of sense to that, at least once you needed
to be able to process things at wirespeed.

Where have you been!?
I've been right here, serving high bandwidth content for many years.
You have just described the P2P traffic that ISPs and other network
operators have been complaining about since the dawn of this century.
No. I've just described something much worse, because there is the
potential for so much more volume. TiVo implies that the device can do
speculative fetch, not just the on-demand sort of things most current
P2P networks do.
TiVo is just one of a thousand brand names for "home computer".
If you want to define "home computer" that way. Personally, while my
light switches contain microprocessors, and may be reprogrammable, that
does not mean that I view them as computers. I don't think I can run
X11 on my light switch (even though it's got several LED's). I don't
think that it's a good idea to try to run FreeBSD on my security system.
I don't think that I'll be able to run OpenOffice on my Cisco 7960G's.
I'm pretty sure that my thermostat isn't good for running Mahjongg. And
the TiVo probably isn't going to run Internet Explorer anytime soon.
There are microprocessors all over the place. Possessing a microprocessor,
and even being able to affect the programming that runs on a uP, doesn't
make every such device a home computer.
One of these days, we're going to wake up and discover that someone (and I
guess it's got to be someone more persuasive than Apple with their AppleTV
doodad) is going to create some device that is compelling to users. I do
not care that it has a microprocessor inside, or even that it may be
programmable. The thing is likely to be a variation on a set-top box, is
likely to have TiVo-like capabilities, and I'm worried about what's going
to happen to IP networks.

I would say that splitting the market for content into many
small slivers (a forest of shards) is pretty much a revolution.
Agreed I'm not sure it'll happen all at once, though.
Whatever technology is used to deliver this forest of shards is
irrelevant because the revolution is in the creation of this
information superhighway with thousands of channels. And even
though the concept predated the exponential growth of the Internet
let's not forget that the web has been there and done that.
Ok, I'll accept that. Except I'd like to note that the technology that
I have seen that could enable this is probably the Internet; most other
methods of transmission are substantially more restricted (i.e. it's
pretty difficult for me to go and get a satellite uplink, but pretty much
even the most lowly DSL customer probably has a 384k upstream).

This is key. Any scenario that does not expect the end user to amass a
huge library of content for later viewing, is missing an important
component. And if that content library is encrypted or locked in some
way so that it is married to one brand name device, or pay-per-view
systems, then the majority of the market will pass it by.
I ABSOLUTELY AGREE... that I wish the world worked that way. ( )

Bottom line is that our networks must be paid for. If consumers want to
use more of our financial investment (capital and opex) then we will be
forced to raise prices up to a level where it limits demand to what we
can actually deliver. Most networks can live with a step up in
if it levels off because although they may lose money at first, if
dips and levels then they can make it back over time. If the content
do not want this dipping and levelling off, then they will have to foot
bill for the network capacity.
That's kind of the funniest thing I've seen today, it sounds so much like
an Ed Whitacre. I've somewhat deliberately avoided the model of having
some large-channel-like "content senders" enter this discussion, because
I am guessing that there will be a large number of people who may simply
use their existing - paid for - broadband connections. That's the PTA
example and probably the "Star Trek: Hidden Frontier" example, and then
for good measure, throw in everyone who will be self-publishing the
content that (looking back on today) used to get served on YouTube. Then
Ed learns that the people he'd like to charge for the privilege of using
"his" pipes are already paying for pipes.
And if they want to recover that cost from the
end users then they will also run into that limit in the amount of money
people are able to spend on entertainment per month.
Broadcast models were built based on a delivery system that scaled up as
big as you want with only capex. But an IP network requires a lot of
to maintain any level of capex investment. There ain't no free lunch.
I certainly agree, that's why this discussion is relevant.

The only difference from 1965 network TV is that in 1965, the networks
had limited sources capable of producing content at a reasonable cost.
But today, content production is cheap, and competition has driven the
cost of content down to zero.
Right, that's a "problem" I'm seeing too.
Only the middleman selling ads has a
business model any more. Network operators could fill that middleman
role but most of them are still stuck in the telco/ISP mindset.
So, consider what would happen if that were to be something that you could
self-manage, outsourcing the hard work to an advertising provider. Call
it maybe Google AdVideos. Host the video on your TiVo, or your PC,
and take advantage of your existing bandwidth. (There are obvious non-
self-hosted models already available, I'm not focusing on them, but they
would work too)

If this really happens, then some companies will fix their marketing
and sales contracts, others will go into Chapter 11. But at the end
of the day, as with the telecom collapse, the networks keep rolling
on even if the management changes.
I would think that has some operational aspects that are worth talking

You're right. People are already building YouTube clones or
adding YouTube like video libraries to their websites. This
software combined with lots of small distributed data centers
like Amazon EC2, is likely where local content will go. Again
one wonders why Google and Amazon and Yahoo are inventing
this stuff rather than ISPs. Probably because after the wave
of acquisition by telcos, they neglected the data center half
of the ISP equation. In other words, there are historical
reasons based on ignorance, but no fundamental barrier to
large carriers offering something like Hadoop, EC2, AppEngine.
That's true, but it's also quite possible that we'll see it decentralize
further. Why should I pay someone to host content if I could just share
it from my PC... I'm not saying that I _want_ Microsoft to wake up and
realize that it has a path to strike at some portions of Google, et.al,
by changing the very nature of Internet content distribution, but it's a
significant possibility. That P2P networks work as well as they do says
gobs about the potential.

Maybe PVR doesn't mean the same stateside as here in the UK.
My PVR is a box with two digital TV receivers and 180 gig
hard drive that connects to a TV screen. All interaction is
through the remote and the TV.
Then it's part of your TV system, not really a personal computer.
The difference between this
and P2P video is only the software and the screen we watch it on.
By the way, my 17-month old loves YouTube videos. There may
be a generational thing coming down the road similar to the
way young people have ditched email in favour of IM.
That's possible, but there are still some display ergonomics issues
with watching things on a computer. AppleTV is perfectly capable of
downloading YouTube and displaying it on a TV; this is not at issue.
iPhones are _also_ capable of it, but that does not mean that you are
going to want to watch hour-long TV shows on your iPhone with the rest
of your family... that's where having a large TV set, surrounded by
some furniture that people can relax on comes in.
In any case, the point is still that I think there will be a serious
problem if and when someone comes up with a TiVo-like device that
implements what I like to refer to as InterneTiVo. That all the
necessary technology to implement this is available TODAY is completely
irrelevant; it is going to take someone taking all the technical bits,
figuring out how to glue it all together in a usable way, package it
up to hide the gory details, and then sell it as a set-top box for
$cheap in the same way that TiVo did. When TiVo did that, not only
did they make "DVR" a practical reality for the average consumer, but
they also actually managed to succeed at a more abstract level - the
device they designed wasn't just capable of recording Channel 22 from
8:00PM to 9:00PM every Wednesday night, but was actually capable of
analyzing the broadcast schedule, picking up shows at whatever time
they were available, rescheduling around conflicts, and even looking
for things that were similar, that a user might like. A TiVo isn't
a "DVR" (in the sense of the relatively poor capabilities of most of
the devices that bear that tag) so much as it is a personal video
So what I'm thinking of is a device that is doing the equivalent of
being a "personal video assistant" on the Internet. And I believe it
is coming. Something that's capable of searching out and speculatively
downloading the things it thinks you might be interested in. Not some
techie's cobbled together PC with BitTorrent and HDMI outputs. An
actual set-top box that the average user can use.

If it were not for these market data feeds, I doubt that
IP multicast would be as widely supported by routers.
If it weren't for the internet, I doubt that IP would be as widely
supported by routers. Something always drives technology.
The hardware specifics of this is getting a bit off-topic, at least
for this list. Do we agree that there's a potential model in the
future where video may be speculatively fetched off the Internet and
then stored for possible viewing, and if so, can we refocus a bit on
