1184.0. "CD Programming" by COOKIE::KITTELL (Richard S. Kittell - Database A/D) Fri May 06 1988 16:02

From what little market research I've done, the CD player designers have got
the wrong idea about programmability. Their designs are easiest to program
when you want to play only a few tracks. But about the only thing I use the
feature for is to exclude a few tracks, ala /EXCLUDE. So "programming"
involves selecting all those tracks except the ones I want to exclude.

Am I alone, or do others typically use the inverse of what is provided?

This is only a minor annoyance, but I've been looking at machines that have
persistent recall of programming specific to each CD. The only system I've
found so far is FTS (favorite track selection) on Phillips and Magnavox
(same thing). Sorry, I don't have a model numbers. The non-volatile storage
is unformatted (no pre-allocated disc directory), so the number of
discs that can be stored is related to how many tracks you store for each
disc.

The Phillips machine I looked at had a 2kb NVRAM. The memory usage was 8
bytes per CD plus 1 byte per selected track. There must have been some other
overhead because they gave figures like 155 discs at 5 tracks per disc,
which only uses 2015 bytes.

If I only exclude 1 or two tracks, I'm really going to eat up that
storage fast. If the cost was 8 bytes plus 1 per track excluded, I'd be able
to put many more discs in.

I realize that select gives one the ability to change the order, but I'd
rather have exclude. An RS232 plug on the back of the player would be an
acceptable alternative...

1184.1Programming helps you play singlesBAVIKI::GOODMichael GoodFri May 06 1988 17:034
    I use programming primarily to turn my rock CD's into a programmable
    45.  Often I'll just want to hear 1 or 2 songs from each of several
    CD's. Programming makes it really easy to do that, and is one of the
    big reasons I like CD's.

    I use programming mainly when I'm making tapes to play at work.
    Mostly, I'm excluding tracks, but occasionally I need a track
    from another disc.
    
    What I wish is that there was a way for the disc to tell the
    player that two tracks are `linked'.  That way, tracks that
    are really introductions to the following track would be
    played as one.  That would be nice in shuffle (random) mode.

    Yes, that would give me an incentive to buy a home computer.
    
    Are there any home CD players that can be controlled externally?

    My first CD player, a Maggie 2020, had the "exclude" feature you
    would like. I didn't often use it -- mostly, I used it when putting
    CD's onto tape for the car, and wanted to cut a track or two from
    a longer_than_45_minute CD so it would fit on one side of a tape
    -- but it's still a useful feature to have. I wish my current player
    (Pioneer CLD-1010) had that feature. I *could* just program all
    of the tracks *except* the one or two I want to leave out, but the
    Pioneer only accepts 10 program items, and one disc that I have
    in mind for transfer to tape would have more than 10 tracks to
    program. I suppose I'll end up borrowing back the Mag from the
    friend it's loaned out to in order to do the taping.
    
    The Pioneer is nifty for being able to play both videodiscs and
    CD's (four different sizes/formats all together), which is the
    reason I got it in the first place, but it's lacking somewhat in
    programmability.

    Sony's newest players can also store a program for discs - it seems
    to have a lot more storage available than the Philips players.
    Some models alternatively allow you to set your own "index" points
    for a disc that can be later cued to, and the CDP-707ESD also can
    store a title for a disc that displays while you play it.
    
    I think certain Sony models allow "track delete" programming,
    and I have seen Akai ads claiming such a feature too (the "without"
    key).
    
    I have seen RS-232 controlled CD players, but they are professional
    models and very expensive.
