Standard For MP3 CD Players Planned For March

udif writes: "OSTA, the Optical Storage Teechnology Association, (a standards body whose members include HP, Sony, Ricoh and others, and among other things, has defined the UDF filesytem for DVD's), is proposing a standard format for storing MP3's on CD, called CDA. Here is a quote from their press release: 'Many recently produced DVD players now have the ability to play back MP3 or WMA files. However, these players sometimes lack the ease of use of an audio CD when playing CD-R or CD-RW discs with MP3 or WMA files. Due to lack of standard format, discs containing MP3 or WMA files made in today's PCs with standard CD recording software often exhibit long initialization times and lead to a poor user experience ... CD-Text capable CD/DVD players will be able to display the names of artists and song titles and navigate the hundreds of MP3 or WMA files easily by selecting play lists or other criteria.'" CDA, by the way, stands for Compressed Data Audio. Seems like a good step toward at least good labeling of which players can play your shiny disks, whether they hold MP3s, home video in VCD format, or your digital pictures. Demo units using the spec should be at next month's Comdex.

  5. Much needed... by slim · · Score: 2
    Some sort of UI standard might be very useful. I have an LG 3350e DVD player which professes to double as an MP3 player. It's lucky MP3 wasn't a major factor when I decided to buy it...

    What I'd expect a CD MP3 player to do when you put in a disk and press play is something along the lines of:

    find $CDMOUNTPOINT/ -name '*.mp3' -exec mpg123 {} \;

    i.e. play each file in the order you find them.

    What the LG does is:
    • Read the entire directory structure -- this takes several minutes for a CD at full capacity
    • Display the directory in an MS Explorer style GUI (thereby requiring the TV to be switched on, bah!)
    • Select each track you want played individually (there will be several hundred on a CD)
    • then press play


    This is hopeless.

    Of course, it's not really a standard that's required, it's someone working on the product who's actually prepared to think about what a consumer might want from an MP3 player, rather than just wanting to be able to put a tick on the spec sheet.

    I don't see why they can't just make the CDA format itself .. uh .. format-independent. That is, make no assumption about what type of compression is being used: include a space to indicate what format is being used and let the player decide if it can play that format or not, like AVIs.

    Include a space in the specification for new codecs (store them in RAM rather than ROM), and this could be expanded much further. Imagine DVD players that can be flash updated on-the-fly to play DivX movies written to CDA discs, CD players that handle discs with songs in 20 different formats, and so on. Jeez. That'd be cool. Is there any way we can submit this kind of stuff to them?

    You won't see that happen for a long, long time, if ever. And you certainly won't find upgrade flashes that are free.

    The only way these companies stay in business is making sure that every time there is a new standard you have to go out and buy a new player. If you only had to buy one player (and upgrading was free) that would be the end of them. They don't want that. And we all know that consumers exist for the express purpose of serving the needs of big business.

    Oh, and just in case consumers get cocky enough to believe that they are important, there are courts, laws and government bodies. All of which are in place to make sure that we consumers don't get out of line and try to hold back corporations from making money. But, that's just my theory.
