  1. Re:Dual G5 requirement should be improved on EFF Reviews HDTV PVR Solution for Mac · · Score: 1

    My experience has differed from yours. And, I think there are plenty of other reports out there to prove that MPEG2 acceleration is not a "lie". Do a google search and you'll find a lot. You'll also find a lot of comments on problems getting it working well. Or, you can even look at source code from the Linux apps implementing XvMC to see exactly what is being offloaded.

    I have had Fusion cards for almost two years, and I originally used it with a 1GHz P3. The HD playback with DxVA acceleration was good on that system. (although, at that time the Fusion software was not exactly reliable, so the overall solution wasn't great)

    Software playback is also much more sensitive to other system issues. You have high CPU utilizatin, and high AGP Bus utilization. So, it's sensitive to any resource limitations. On a system that had interrupts shared among multiple devices, I would often get stutters in the video and audio glitches. With some of the video drivers I tried, I had big problems with DxVA. So, everything needs to be working well. But, when it is, DxVA works well.

    > That is a marketing lie which was commonly told a few years ago.

    Actually, No.. DxVA is what makes the CPU requirements reasonable, even with the software decode products. The 2.4GHz -> 800MHz was specifically addressing DxVA offload of HDTV MPEG2 decode.

    I have two MyHD cards and two FusionHDTV cards. The MyHD cards have an onboard MPEG2 decoder and they display the HDTV output directly from the receiver card - not through your video card. It does the complete MPEG2 decode in hardware, so the CPU requirements on the host are VERY low. You could do it with a Pentium II.

    The Fusion cards only do the reception of the ATSC Transport Stream - they pass that 20Mbps data stream to the host for processing. All MPEG decoding and display is done in software (which is the same as with the Sasem USB HDTV device, ATI HDTV Wonder, pchdtv.com HD-3000 for Linux, and the EyeTV 500). In this model, the decoding is done on the CPU in software, and some of the more compute intensive portions are offloaded to the video card via the DxVA API. Specifically, the iDCT (inverse discrete cosine transform) and motion compensation are hardware accelerated. So, it still takes a decent CPU, to do the MPEG decoding, but much less than for full software decode. On my Athlon64 3400+, the CPU utilization goes from ~ 70% to ~ 35% when I turn DxVA on.

    I prefer the MyHD cards for a number of reasons. But, their main drawback is flexibility. They just do the HD video output. If you want to integrate with a PVR solution, like XP Media Center, you need the video to be displayable on the PC video output. So, the hardware decode cards are becoming less popular.

    > Also it is worth noting that although Apple's DVD player uses MPEG2 acceleration it still doesn't do de-interlacing decently. You can probably get better results with VLC.

    That's just a limitation of Apple's software.. DVD Player is not exactly renowned for its video quality.
    The video hardware and MPEG2 accel are fully capable of good de-interlaced display. The FusionHDTV software does a good job of de-interlacing 1080i output when using DxVA. It looks almost as good as the output from the MyHD.

  4. Dual G5 requirement should be improved on EFF Reviews HDTV PVR Solution for Mac · · Score: 4, Informative


    A dual G5 requirement for smooth HDTV playback is a big problem. You should be able to easily do this with a midrange G4 system.

    The problem is that Apple has not opened the API for the MPEG2 acceleration available in most of the video chips in Macs. ( The equivalent of DxVA in Windows, or XvMC in XFree86 ). In the x86 world, this takes the CPU requirement down from ~ 2.4GHz P4 to ~ 800MHz P3.

    Apple's DVD player uses the MPEG2 acceleration, but they don't allow others to use it. So, we're stuck with extremely high CPU requirements of dec oding those hi-res HDTV files.

    But, the point is that this is an example of what is to come in the general purpose computing arena. There are a number of initiatives already well along on the PC side that will look an awful lot like this.

    BIOS manufacturers are implementing several DRM security mechanisms, which will work with the OS DRM mechanisms that microsoft is putting into the OS. These will be required components for HD-DVDs to work in PCs, or for Digital TV tuners which support the broadcast flag.

    Basically, the content producer will decide how your PC is going to operate, not you. Your Digital TV tuner will not pass the HDTV Transport Stream to the host PC unless it is encrypted. So, any modification of the content (downscaling to resolution for smaller files, cutting out commercials, or just taking samples of the video) will not be allowed.

    So, no.. don't just bury your head and say it's not a big deal, or claim that someone will just crack the security anyway. If people are complacent, they will end up with what Bill Gates and Disney think are reasonable usage rights, and hobbyists or small startups will be locked out of any innovation in this space.

The CableCard is a PCMCIA card that works with the cable security system to allow viewing of premium channels, PPV, etc. CableCard support is currently available in several high end HDTVs (it's only in the high end units now, because it requires a built-in HD tuner).

It was only after GMail came on the scene that they increased their storage and added several usability features (but they are still not even close to GMail).

    Yes, at the user side there is nothing directly needed to support SecurID authentication. But, on the application server side it needs to be built into the app using RSA's API. But, since SecurID is so broadly deployed, pretty much all security related applications implement SecurID auth.

    For corporate uses, it's much easier to dictate Smart Cards, and integrate a bunch of different corporate applications - multiplying the benefit of the card.

    But, thinking about the problem a bit more.. I guess that clunky two factor authentication processes solve some real problems. They protect against worms/viruses reading all the stored passwords on a users's system. They also minimize the risk of the phishing scams, because the passwords only last 60 seconds. Although, they don't totally eliminate the risk. A phishing site could ask for the SecurID code, then connect out to the bank site in real time to authenticate and do what they want.

    Google will continue to innovate, developing new features, integrating new capabilities into the developing 'user portal' centered around GMail. They will continue to develope advanced ways to organize, search, and use huge amounts of data.

    Microsoft will wait to see what the users gravitate to the most, and will create a nearly identical version of the feature. They will extend it in a few minor ways to integrate more tightly with their operating systems. Since it will be in the OS by default, they will quickly gain a large market share.

    On a lesser note, other 'competitors' like Yahoo, will continue to innovate in areas of banner advertising, and flash advertisement integration. They will add new features only after Google releases products that make theirs look primitive by comparison.

    Why not go to a modern smart card system? It can store full certificates, and tie directly into really strong security/crypto. Tie the smart card / cert into the autentication of your system, and into IPSec, SSL, etc.

    SecurID offers only the authentication piece, based on a completely closed algorithm.

    While even in startups the executive option profits can be obscene. More reasonable rewards are often achieved by the rank and file developers and marketing types. If accounting changes are made, guess who will lose out? Yeah, it won't be the execs. Us little guys will no longer have the potential for good gains.

    Will the equation change at all for Pre-IPO companies, where the shares are not on the open market? Can they report a share price below what it would probably go for in the open market? Can they grant shares, effectively giving ownership of the company, rathern than options - and would that make a difference?

    Once a company goes IPO, it seems like this would make it tough to "get over the hump" to being a larger company where they can absorb option costs without totally killing reported profits.

    Maybe it's time to look for one of those stable corporate IT jobs, with all salary compensation. The IPOs are a lot more risky these days, and reducing options will not leave much incentive to stay.
