Most Hackable Coupon-Eligible DTV Converter?
An anonymous reader writes "So I've finally gotten my DTV coupons, now I have to choose a converter before the analog signals go dark. I'd like to get one that is hackable, but haven't had much luck finding information about the internals of the units available. My question is: What chipsets do the different coupon eligible converters use, and which one is the most hackable? It'd be great to be able to send my own MPEG stream and have it displayed, or to grab the raw stream out of the device."
The little Apex 502 is one of the few coupon eligible converters with S-video out.
If you have a TV or monitor with S-Video inputs, you'll get a better picture than using RS170 composite video (and much better than CH3/4 RF)
yeah I tend to agree. I live in an apartment where my analog channels weren't perfect but were watchable (and audible), even with static. I get quite a bit of interference on and off and it's rather annoying when a digital signal cuts or has problems and the sound goes out entirely (even if the picture is just blocking)until it picks back up (sometimes the picture as well). It's quite a bit different than getting a bit of static (or even a big burst of static) in the picture and sound on an analog channel where it may be annoying but I don't miss anything (less it goes completely out).
To me the sound is the most annoying aspect and almost seems like there is less tolerance there. Then again, digital cable isn't much better either, in fact its worse because of the higher compression and more outages I have gotten with it. In the cable arena I preferred analog over digital by far. As far as over the air, the quality of the picture and sound is so much better when it comes in, but there really does seem to be less tolerance for when it doesn't. Video and sound with some static in them is much more followable to me (maybe just me) than blocking video or sound that cuts out entirely.
Again, I live in fairly old apartments. Another thing to consider is that with the frequencies that analog used, many were more resilient than what digital uses. Basically the VHF channels are probably what most people use to compare analog to digital. Since digital is closer to your UHF channels (which could be non-existent due to interference in some places) the only real comparison is with them. Basically the digital signals will only be as good as the weaker set of the analog signals. Going by that, digital (based on frequencies used as opposed to method used) is probably going to be worse in many cases than people used to watching VHF channels alone.
In other words, NBC/CBS/ABC, given a user with weak UHF before and similar power output by the stations, is going to be worse than before as far as interference because it's no longer in the VHF spectrum. I consider it worse when I cannot follow the show (sound cutting off or the screen blocking where I cannot see the picture compared to sound with static and a picture with static - since I can follow a scene with quite a bit of static) So saying that over-the-air HDTV is better than over-the-analog (or vice versa) is really just BS since it's apples and oranges (unless you leave out VHF, which was the meat of analog). That's also why DTV antennas are so similar to UHF antennas.
In case any of you are interested, I took photos of my teardown of the Zenith DTT900, one of the first available DTV converters, available here: http://nuxx.net/gallery/v/acquired_stuff/zenith_dtt900/.
HDCP dummies *do* exist. A mate bought one 2 years back after he discovered that HDCP wouldn't let him send HD content to his 12k UKP SIM2 rear projection HD TV, as it was an early model that didn't have HDMI. We suspect they spoof the encryption key of common HDCP devices by other major manufacturers, so it would be difficult for the keys to get blacklisted. Works great, was quite hard to buy...!
