I'm an earlier adopter with my mythTV box and fast connection. But I'm really keen to see the move to getting TV shows over IP. Cable's bulk pricing just isn't doing it for me any more.
Hard disk drives these days are cheap. Too cheap, in that while we love paying 30 cents/GB, the reliability is getting pretty poor. Doing backups, especially automatic backups is a must, but what about RAID?
One of the problems with RAID, at least RAID-5 is that you need to have 3, and ideally 4 or 5 drives in a machine. That's a lot of drives, a lot of power, a lot of heat, a lot of noise. And many machines only have two IDE controllers so they can barely do 3 drives and can't readily do more even if they had the slots and power for them.
So I propose a software RAID-5, done over a LAN with 3 to 5 drives scattered over several machines on the LAN.
Slow as hell, of course, having to read and write your data out over the LAN even at 100mbits. Gigabit would obviously be better. But what is it we have that's taking up all this disk space -- it's video, music and photos. Things which, if just being played back, don't need to be accessed very fast. If you're not editing video or music, in particular, you can handle having it on a very slow device. (Photos are a bigger issue, as they do sometimes need fast access when building thumbnails etc.)
This could even be done among neighbours over 802.11g, with suitable encryption. In theory.
Not that there aren't some major issues to overcome. The machines must be on most of the time. (A single disk can be taken out of a RAID temporarily, and thus a single machine hosting one disk can be turned off or rebooted, but not for long periods.) If you lose access to two disks (or your LAN) you can't get access to the data. And it's going to use a lot of your network capacity, though gigabit networking is starting to get cheap. And the idea gets better...
(You might want to see Tivo's actual press release about being able to move programs from a Tivo to an iPod.)
ALVISO, CA -- NOV 21, 2005 -- TiVo Inc. (NASDAQ: TIVO ), creator of and a leader in television services for digital video recorders, today announced an enhancement to it's system which actually allows the copying of files from one computer device to another, at least if its one of their partner devices.
I was amused to hear folks on PRI's Marketplace radio program say that 99 cents for a rerun on the video iPod was a good price. Turns out that 99 cents includes commercials in that rerun, because people polled said they would rather pay 99 cents with commercials intead of $1.50 without them.
Yesterday I visited Tag Camp an impromptu weekend conference on tagging in the spirit of Foo Camp and the Bar Camp I wrote about earlier. User-applied tagging has become all the rage on sites like fickr and del.icio.us. I was pleased when one person at the conference saw my name and said, "hey you started all this."
IPTV is the new buzzword for video over IP, in particular as it relates to DSL/phone companies wanting to compete with cable companies and give you TV using your DSL. (The cable companies are hard at work at giving you phone service over your cable modem.)
At every conference I go to, with a few rare exceptions, we always see people wasting time fiddling with computers and projectors in order to show their presentation, which is (sadly) almost always in powerpoint. Many laptops won't switch displays until they see a monitor on the VGA port, which makes things take longer.
So how about a wireless protocol for sending presentations from laptops to projectors or a computer connected to the projector. Over 802.11 or bluetooth, presumably.
You are probably familiar with Google adsense, which is providing the ads you see on the right hand side of this page. Adsense code examines the text of pages, and tries to match Google adwords bids against it. The publisher of the page gets some undisclosed share of the Google revenue.
I wrote before on the ideal car dock for an MP3 player but the truth is we could use something even simpler sooner. On my recent trip, we brought the cassette adapter but there was no tape player in the rental car. We forgot the FM transmitter, but that's not as good anyway.
So right away let's see a small headphone plug on the car stereos to do a nice aux input, especially if you are taking away the tape. Duh.
Sunday, I was invited, along with a crowd of other local friends and bloggers, to a preview screening of the new art film "Yes" by Sally Potter. I'll review Yes, but what was interesting was the idea of Sony Pictures doing free screenings of movies for the "blogger" demographic. As I noted earlier, I'm also in this group called the "Silicon Valley 100" where they send us free stuff in the hopes we'll generate buzz and useful feedback. (The last few products they sent have not been exciting enough to inspire me to write about them, though.)
I'm writing a larger essay on this topic, but I recently posted the following to Interesting People and it was requested to put it here. It relates to the theme of "light" DRM.
I used to wonder if you made a DRM system that was so well designed that only a serious pirate would notice it was there, if this might be a workable system.
I've written before about the dichotomies between serial and browseable, between writer-friendly and reader-friendly.
One idea that now seems obvious is to integrate wiki functions into a mailing list manager (particularly one that does a web interface to the mailng list.)
On both a personal and professional note, I am happy to report that the federal courts have unanimously ruled to strike down the FCC's broadcast flag (that's a PDF) due to our lawsuit against them.
When people watch TV with a hard disk video recorder, they always watch the show delayed, often by hours or many days. They all watch it at a different time.
Earlier I reported on Peerflix, which is implementing a P2P DVD sharing system with similarities to some of my own ideas. I have tried it out a bit now, and learned a bit more. I also have updated experiences with Peerflix.
The web site is marked beta and still very buggy, which is bad, but my first try on the service was first-rate. I mailed off my first DVD, Eternal Sunshine of the Spotless Mind,
on Wednesday to somebody in San Jose (who almost surely got it today) and got the replacement for it -- by strange coincidence another memory-related movie called Memento in the mail today. That is faster than most of the services, though people like Netflix could be this fast if they decided to take the same step and trust you when you said you mailed a disk, rather than waiting for it to arrive.
All this is good, but there's still a killer flaw in the idea of actually selling the DVDs. All DVDs will have a limited lifetime of high-demand. As demand drops below supply, somebody holding the DVD at that time will get "stuck" with it, though you can fix that by being fast on the draw in agreeing to be the one to mail any new requesters that do come along.
For the past couple of years, I've been mulling over an idea for a different kind of DVD "rental" company, similar in ways to the popular NetFlix. Now I have encountered a new company called Peerflix which is doing something similar. Is it annoying or vindicating to see somebody else run with something? :-)
So instead I will comment on Peerflix, which I am going to try out, and what I planned to do differently.
Ok, it's strange because I think one of the whole points of the hard disk video recorder / PVR is that you are not supposed to watch live TV any more, not supposed to channel surf -- but I keep coming up with ideas relating to it. Maybe I have a secret desire to surf again.
As many people know, with digital recording, the no-surf rule is enforced because it's harder to do. The digital delay introduces a long channel change delay, intolerable when combined with another delay (satellite/cable box).
I notice from this chart in advertising age (which requires an annoying complex if free registration form) that there's been a giant jump in the CPM (cost per thousand viewers) of a 30 second Superbowl ad. From 1968 to 1998 it hovered close to $10 in constant dollars -- or about a penny per impression.
Then there's a big jump (thanks in part to Fox and the dot-com boom) and now it's up to $25. But they're still paying, even though the $10 figure is more common for regular TV.
