Economic problems that hurt the country can't possibly their fault, it must be the fault of dissenters and other wrong-thinkers who must be punished, so that profit by a few corporations can somehow stimulate the economy.

If us normal people have our income cut in half by bad policy making, government feels a tiny pinch. If Corporations or wealthy people have their income cut in half, Government will go bankrupt at its current spending rates. This is a problem of inefficient central control, I think. It makes Government dependent on the profit of the wealthy, and since central control will tend to make 'The People' dependent on Government...well, follow the chain.)

It is illegal to make a copy of it so you don't get the CD scratched up. And it's illegal if you're caught with it. How long before your computer is reporting everything you do to the corporation you are buying the music from? "John Smith is playing this song 4 times a day, we better up the price a bit so we get some more money out of it. Oh wait, today he stopped listening to the song. Flag him, he may have found another way of listening to it."

Compare this to the RIAA! The RIAA doesn't want Napster around, so it sues it to death. The RIAA doesn't want MP3.COM around, so it sues it to death! THAT is where the Hitler image came from.

    Blockquoth the poster:

    Having said all this, record industry does have the right to implement copy protection.

    I've thought about the following for a while. There ought to be a two-track system of copyright. Whenever anything is released for public consumption, the publisher would make a choice:
    • Forego any technical copy protection -- the data is presented in the clear. However, stringent and heavy penalties accrue for copyright infringement, and the publisher can utilize the court system to recover these penalties.
    • Encrypt the data or otherwise protect it by technical means. In this case, however, no penalties would follow from circumvention of the encyption ... the works would, in essence, be public domain, with only the encryption providing protection (= revenue stream) to the publisher.


    In other words, the content publisher doesn't get to eat his/her cake and have it, too. By restricting Fair Use access, by cordonning off the material from the public domain (essentially forever), the publisher loses the protection of the courts. If you don't want to play ball with the justice system, you don't get to use it, either.



    This approach is entirely justifiable, as copyright is a privilege granted by the state, not a right inherent in the content. As Litman and others point out, historically, copyright has been viewed as a bargain between the publishers and the public. If publishers try to unilaterally change the terms of the game -- by, for instance, encrypting data streams -- then the public has every right and justification to revoke the copyright.

    Back in those bad old days I worked for Xanaro, a competitor of Lotus and after a fairly serious analysis of the cost/benefit ratio, we elected to ship without copy protection.

    The issue we were seeing was customer resistance to disks that were "defective". End users weren't terribly technical, and tended to call a colleague company's help line whenever their disks didn't read.

    Of course, stealing copies of our program was as illegal as breaking copy protection is now, and that was sufficient for the majority of our customer base. When a customer called our help line with what turned out to be a stolen copy, we first helped them, then arrange for them to get a copy of the update release (with some bug fixes they needed!) for the regular update price.

    I recollect actually going out to both a local college and high school and helping them set up whole labs of our product after they agreed to put us on next year's budget at the reduced academic rate (;-)).

    My conclusion? Companies selling ordinary CDs without copy protection will have a business advantage over the ones trying to shoulder both the costs of DVDs for normal-fidelity audio and the support costs of "copy protection". Scofflaws will further reduce the profitability of copy-protected DVDs if they target them preferentially...

  13. Error detection, etc..... by filtersweep · · Score: 2, Interesting

I am very curious how this software (vs. a freebie ripper) would handle a "protected CD"- (unfortunately there isn't any protected music worth buying).

    I realize Universal has implied that this is a hardware issue, but I have a hard time with that "line"- my guess is that anyone could write software "error detection" that emulates that of an audio CD player capable of playing a "protected CD". My understanding, and I may be wrong here, is that a PC's CD drive uses a more exacting form of error detection (since they spin faster, and let's face it- one bit of error sneaking by in your walkman's CD playing in real time can be interpolated with less impact than on a data CD for a PC).

    I also find it difficult to believe that all of the glass mastering facilities have been retooled to accept masters with "errors." Obviously there is a great difference between "pressing a CD" and burning one- and the error tolerances are very different.

    The actual digital data of a CDDA file is identical to that of a .wav file at 44.1 sample rate, 16 bits... no format conversion occurs. The only issue is the layout on the CD- but the raw data is identical. I seriously cannot believe that this cannot be extracted intact through software.

    Labels need to realize that a compressed format such as mp3 poses a legitimate compromise to fidelity. It is not unlike making a mix tape on(cassette). Granted many people also are copying entire CDs with the wave audio intact, but if the labels wanted to show a gesture of good faith, they would INCLUDE mp3s at a decent audio quality (above 128!). This would at least make purchasing the CD "valuable" (since it is higher quality than mp3).

    But keep in mind that we will soon see high resolution audio on DVD, and the labels will try to resell you your entire collection with audio at least at 24 bits, and likely twice the sample rates... likely with surround sound mixes, etc. This of course if overkill considering most people's listening environments. Again, this could be viewed as a value added service worth paying a premium (and I consider the cost of a new CD at that price point, considering what little you get for your money). An mp3 will look like a very inferior medium to those with discerning ears.

    To address another point someone raised, it will be VERY EASY to fill a DVD audio CD- the audio files themselves could easily double if not triple, and they will likely add alternate mixes of the same songs, and dump a bunch of other multi-media crap on them... and probably add "commercials" promoting other artists or products .

    They CANNOT mandate copy protection for PCs. Hardware has historically been ahead of media (think VCR if you must... or cassette tapes). Look what a flop the "pay-per-view" DVD players were... consumers voted with their wallets.

    The DIRECT DIGITAL copy argument does not apply here if we consider that a blank DVD could cost more than a high-res audio DVD (which it could- for the time being). In the meantime, people need to use the technology to unseat the stranglehold that the centralized form of distribution places on content (FOUR major labels controlling everying, including the LAW?!- certainly promotes a grassroots "open source" movement for artists to distribute their wares directly- most consumers would arguably rather pay the artist than the label anyway, and arguably actual production costs are at an all-time low and are headed lower... as long as you don't need that top shelf producer).

    Since neither option would be attractive to most publishers, it would appear that widespread copyright violations (and violators) will be with us for a long, long time.

    Really, the RIAA is facing nothing that retailers haven't faced since the beginning of commerce. While copying (or theft to use their term) is a bit higher than for retail, but their loss per copy is also lower.

    At the same time, retailers have faced a serious threat to their profits for many years that the RIAA never sees in any realistic way....Competition in a free market.

    Imagine starting a new department store in an environment where some sort of DSIA (Department Stores of America) controled every single advertising medium you might use to advertise your existance except for word of mouth.

    One symptom of this state of affairs is that prices are much higher than they would be otherwise. In any sane pricing in a free market, the seller has to strike a balance between profit per unit and consumer willingness (and ability) to pay the price that results. Since the barriers to entry for the music market are artificially high, the RIAA has been able to consistantly keep profit/unit high. At the same time, they have created an unusually large population that really wants music, but can't/won't afford the price they charge. By consistantly making large profits while the artists make very little, they have also made themselves easy to despise.

    That is a combination that makes widespread copying (or theft as they prefer) inevitable.

    Returning to your equasion, I believe it will better reflect the real world as:

    Rc = (Cp - (Ce + Cm + (Ca*Pa))) * Vd

    I agree more or less with your analysis of the controlability of the variables (Though RIAA HAS tried hard to manipulate Cm and Ca through legislation and Ce through stupid copy protection scheme). Note that this version of the equasion subtly changes the meaning of Rc to utility (to the consumer) of copying.

    For the sake of convieniance, I will define Cc, cost of copying, as Cc = (Ce + Cm + (Ca*Pa)).

    Note that in any case where Cc < Cp there will be negative utility in copying. In those cases, the RIAA is a commodity manufacturer and gains it's profits from the efficiencies of mass production vs. individual copying.

    I believe that the RIAA CAN compete with Gnutella! There is value in not having to hassle with crappy quality tracks, nodes that are too busy, or never seem to actually provide the tracks they claim to offer, misnamed tracks, etc... In addition, video tracks in free and open formats can also up the Cc without 'cheating'. If Cp is low enough, the only people who will copy are people whose time is worth nothing (who couldn't pay anyway since they are unemployed and unemployable).

    The RIAA can also boost their profits through business innovations. At a low Cp, they might be best off by terminating their expensive ad campaigns and instead producing a subscription based review service. They could also capture value by charging a nominal fee to broadband providers to colo a music server (yes, charge a fee to allow a provider to colo!). The provider could then use that as an incentive to sign up and reduce their costs for upstream bandwidth.

    Other sources of revenue could include providing a content rating system for parents and paid advertising in their review media (website, magazine, television show, streaming broadcasts etc).

    In short, they could switch from their current strategy of poisoning every well in town but their own to the strategy that made them big in the first place: providing something of value at a reasonable cost.
