What's humorous is that this would probably also enable a super advanced commerical skip. Most of the time, in order to support random channel access, there are i-frames every couple of seconds at most. With i-frames removed to prevent skipping, commercial skip just has to look for periods of really long iframe gaps and dump all that content (e.g., 2 seconds after last iframe to next iframe gets dropped). Won't work on clear-QAM (e.g., locals), but would work anywhere they implemented this "feature"

This is exactly the reason that many cheap things offer long warranties (or for consumables, unlimited refills [handling fees may apply]). Most people will just say screw it and buy a replacement for a $2 bulb rather than spend what might amount to only $1 for postage/packaging. Unless you're sending back a case of them, it's just not worth your time for the $1 savings.

OSX has focus follows mouse sort of. Between X applications or between terminal instances it works fine, but outside of those two instances it's (ick) click to type. You can get it to sort of work between the browser/mail clients and terminal sessions (e.g., terminal sessions behind the browser/mail can usually be typed in by mousing over them), but it's not terribly consistent. Now if only I could fix the splat-cxv for copy/cut/paste...

Switched video is already being used by the cable companies (well, Time Warner in any event). They've kind-of solved the killing non-cable company dvr's issue with a switched video adapter, which is basically nothing more than a stripped down cable box, and they'd like to kill that with 2 way cable cards. Switched video is really just an extension of the pay per view/on demand stuff, extending it to traditional channels.

All you really need for this is an HDMI receiver with HDCP support but no keys and an HDMI or DVI transmitter. Wire the two chips together, add in a small microcontroller (msp430/cypress psoc class should be sufficient) to manage the link. Keyless receiver/transmitter chips use a simple I2C eeprom to store the keys externally on the assumption that you've paid the HDCP consortium for the keys (chips with built in keys require you to sign a license deal in order to purchase them). Use your pc to generate a valid sink key, program that into the eeprom, write some relatively simple code to manage the receiver/transmitter and your done. Analog Devices used to sell a dev board that would be perfect for this purpose - it contained all the necessary parts, save the microcontroller, so would need to build that part of the system. A bit of overkill for this kind of project, but it would work.

And the number of embedded Linux systems with ludicrous boot times that could be improved by something like this is quite high. Think of that BluRay player that takes 90 seconds to open the tray from power off, or your new LCD TV that takes 30 seconds to produce a picture, or your Tivo that takes minutes to be ready to do anything. The vast majority of these devices run embedded linux and getting the boot times down to sub 10 seconds would go a long way to making customers much happier. I know I'd be much happier with consumer electronics if I didn't have to wait so much for things to boot (and sadly, since I've been doing embedded Linux for the last 8 years, I'm probably responsible for some of it...) Yeah, this demo is certainly a contrived example - I'd guess that they've stripped the kernel and u-boot to the bare minimum, loading from parallel flash instead of serial, no arbitrary delays anywhere and init is probably the application they're demoing.

Disclaimer: I work for LifeSize Communications, so I might be biased...

Anyway, in the dedicated hardware area, you've got HP and Cisco at the high end (100k++++), Polycom and Tandberg (merging with Cisco) in the middle end (10k++) and LifeSize and a host of other smaller players at the low end (<20k). If you want HD (720p30 minimum), you're not really going to find it on PC based implementations, most are limited to 640x480p15 - 30 due to the compute required to encode the stream efficiently. Polycom and Tandberg offer a mix of SD and HD products with the SD products generally being cheaper than the HD ones. Everyone in the "professional" video conferencing space is moving to HD. LifeSize offers products from 2.5k (passport - 720p30 only, point to point only) to about 17k (room 220, 1080p30/720p60, 8 way multipoint, H.323) with a variety of products in between. We pride ourselves on needing the least bandwidth to achieve certain levels of performance (e.g., we'll do 720p30 in 768kbps, 720p60 in 1mbps and 1080p30 in < 2mbps). Polycom and Tandberg offerings are generally 2x the bandwidth at the same resolution/frame rate. Cisco's telepresence stuff needs (I could be wrong here, but I think I'm in the right ball park) something like 18mbps for the 3 screen solution you've seen on 24 and a couple of other shows (that's 6mbps/screen).

There are plenty of pc clients, but truth be told, they look like a** compared to the (HD) professional ones in my opinion. Of course, I'm starting to realize that HD TV looks like crap too, so it might just be me.

US Air Force Buying Another 2,200 PS3s 144

Posted by Soulskill
from the quick-who-knows-a-good-ps3-flight-sim dept.
bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."

Most of the CEC enabled players allow you to selectively enable or disable CEC support. And if the software is written correctly (and the path to the TV is not too deep), the source can tell if the sink is on or off, regardless of the connection topology. Of course, most of the CEC and HDMI implementations I've come across are half baked at best.

If I remember correctly, my ancient Sun 3/75 diskless workstation used to state: le0: no carrier when the (AUI -> fiber) ethernet dongle fell off the back of the box (the network is the connector was the old slam against Sun's flaky AUI network connectors of that time). Of course that was before 10baseT was popular, so I suppose it's possible that that form doesn't use a carrier.
