There is absolutely no risk that the SCOTUS is going to prohibit VHS recorders, DVD recorders or for that matter DVRs. It is almost certain that a DVR with a firewire port to plug in extra hard drives gets through.

      The question in Grokster is whether there are genuine, substantial non-infringing uses or whether the theoretical and hypothetical uses being proposed are spurious and the only substantial use is to pirate stuff. Grockster can cease to exist tommorow and none of the copyright use I do is threatened in the least.

      When you are dealling with a bunch of corrupt skunks like Hatch and co it is a good idea to choose something other that a sewer to stand in. Expecting to be able to get any music you want for free is simply not a reasonable or sustainable demand.

      This serves two purposes: First, it allows the developer and the world time to figure out what the technology is good for. P2P networks are copyright neutral -- anything can go over the network. Thus, copyright holders can take advantage of it as well. Second, it prevents copyright holders -- really a subset of them, in fact (even back in '84, some were in favor of the Betamax) -- to extend their copyright on a specific work to what would effectively be a patent on a technology.

      Accordingly, the sale of copying equipment, like the sale of other articles of commerce, does not constitute contributory infringement if the product is widely used for legitimate, unobjectionable purposes. Indeed, it need merely be capable of substantial noninfringing uses.

      The question is thus whether the Betamax is capable of commercially significant noninfringing uses. In order to resolve that question, we need not explore all the different potential uses of the machine and determine whether or not they would constitute infringement. Rather, we need only consider whether on the basis of the facts as found by the District Court a significant number of them would be noninfringing.
      Sony v. Universal, 464 US 417, 442 (1984) (emphasis mine).

      "Potential" is the key word here. It means, in conjunction with the significance requirement, that it is okay if there are no current significant noninfringing uses so long as the technology could be used in such a way. It doesn't matter whether it is now, or even whether it's likely to be in the future. Only potential, regardless of realization, is required.

      Since people could stop using P2P in an infringing manner tomorrow, and start using it in a lawful manner, even if it's unlikely, the Sony test is satisifed.

    - the rise of ISPs (with terms of service discouraging consumer-grade customers from hosting servers), and

Now, here's where people want you to think the losses stop. And they are right, under ideal conditions, namely you copying the file to another spot on your own hard drive. The probability of incorrectly copying without loss is pretty low in that case, unless you have a broken hard drive, which unfortunately, Joe Public who bought his PC at a department store, usually has because the manufacturers of those things use low bid hard drives.

    Anyway, once you start transmitting that gigantic file over the internet, you introduce transmission errors, especially when the transfer is interrupted and restarted several times. Not all file transfer software *correctly* resumes files. Most assumes that the last byte recieved was in fact whole, when in fact it could have been less than all 8 bits....you have to use rollback to be *sure*.

    Optical media such as CDs and DVDs are in fact an analog medium, in that the data is stored as a sequence of dots burned on the surface of the disk. If you *lose* some of that surface, you lose the file. (yes, you can pull most of it off with the right tools, but most people don't know Norton utilities from their ass)

    I don't know about you, but my ten year old CD-Rs that I burned in 1995 are getting CD rot pretty bad. Some of them have the foil flaking off. I lost my original OEM Windows 98 CD to CD rot as well. There is a pinhead sized hole on the surface of the cd where the data layer flaked off. Naturally, that hole is right in the middle of a cab file, and well, you get the picture.

    My twenty year old video tapes may be a little fuzzier than they were when they were new, but they are still watchable.

    Also, if you burn at higher speeds, and most people do, the error rate for the data written to the cd is much higher. That means that as the CD ages and God knows what the color change chemicals on the data layer do over time, the error bits on the CD will protect your data much less of the time.

    Formats such as video cd and DVD are more error tolerant because if a chunk of the data is missing or unreadable the playback device can happily corrupt the display until it hits the next keyframe in the file it is playing....becuase the encoding method is relatively simple.

    More complicated compression formats are smaller, but not so error tolerant, hence you get things like those divx green-screen ghost-trip video files that are found on the p2p networks. Those can be repaired sometimes, but since the file format is corrupt most player software poops out when regular people try to watch.

    IIRC, the video-cd and video-DVD formats actually use the error correction bits on the disc to store more movie data, because it's considered to be no big deal if the picture is fubared for a second or two. (that's what causes those rainbow squares and pauses on a mildly scratched DVD)

    And I don't even want to go into all the things people do to video files to make them fit on media that is too small, like truncation and recompression.

    The bottom line is that while yes, under the right conditions you can make perfect copies of video data after the initial two generations of loss, the media on which you usually store them is *less reliable* than video cassette....

  29. overstated, and missing the big picture by sbma44 · · Score: 2, Insightful

    Yes, burned CDs suffer from bitrot. But most of the other sources of data loss you mention are either very rare or not applicable. Conversions are usually lossy, but they generally don't need to be performed more than once. If someone wants to download a divx rip of a DVD, the original mpeg2 stream has suffered a lossy recompression, yes, but each subsequent transmission of that divx file doesn't result in more loss. This is in contrast to analog formats -- the act of distribution necessarily introduces a loss of quality. That's not the case with digital files. Your concerns about transmission errors and hard disk failures are just silly. These things happen, but rarely, and certainly not in a way that introduces quality defects in the "authoritative" copy of a piece of media on a p2p network (ie, the most popular copy of a file, with same-hash files considered identical (b/c they are)). You might want to have a look at wikipedia's entries under "crc" and "hashing". Your intuition that bits occasionally get flipped is correct, but when it happens it's almost always detected and corrected.

  30. The RIAA/MPAA would LOVE no competition! by hadaso · · Score: 2, Insightful
    Right now they argue about copyright infringement by individuals. But in the longrun, what worries them is competition: competition from independent artists that realize they don't have to sign slavery agreements. And competition from their own past (just like book authors complain now about competition from their own used books on Amazon). They would like to own the net and make the rules!

    The assymetry between uplink and downlink bandwidth for the consumer means that only a tiny fraction of what is available on P2P networks can actually be transferred by the network. A single person sharing files is limited by uplink bandwidth, and cannot really supply more than a few minutes of music a day. What the recording "industry" (actually distributors) are doing when taking individuals to court is actually abusing existing law that was made for a world were infringers would typically be mass infringers that do it for profit. A single infringement means a huge fine, but it was made so by lawmakers in a world where a single infringement caught (a single copied CD)would represent mass infringement (a warehouse full of couterfit CDs somewhere). It is necessary because criminals hide a well as they can, and law enforcement needs to be able to use what evidence they can lay hands on. In P2P networks it's quite the opposite: file sharers don't hide. They make their collections available online for evryone to see without really trying to conceal who they are. Copyright holders can then find individuals offering thousands of tracks. But in reallity these are offered through a very narrow channel: you can see all, but you can only sample very little. But the law can still be used to fine them as if for every track they expose they have a truck full of copies and no constarint on distribution!
