Copyright Claimed on Telephone Tones

awful writes: "Two composers in Australia have copyrighted over 100,000,000,000 phone tone dialing sequences. They state in the article that they are lampooning copyright laws that protect big business rather than artists. Their website has more info and explains how they did it. You can check your number and make sure it hasn't been copyrighted by these guys. They have already recieved one offer of money - from a guy who wanted to purchase the copyright to his number so he could stop direct marketing firms from calling him." Somehow I don't think the inventors of DTMF envisioned this. Update: 10/04 14:11 GMT by M : There's a US mirror available.

prior art? :)

Actually, it was a real problem according to VH1's "One Hit Wonders" show. Not only did the real Jenny get bombarded with calls (yes there was a real Jenny who gave her number to one of the band, and it was 867-5309), but everyone else in every area code as well.

This absolute waste of bits known as pop culture trivia was brought to you by the letters L, O, S, E and R.

Well, now I'll have to get a rotary cell phone so I can call home without paying royalties!

I'm afraid the DMCA will bite you on the ass for circumventing.

Turn about is fair play (pun intended)

[Soko]

Ooo!Ooo! I know what these guys can do for us - sue Hillary Rosen or any RIAA member when they have to call each other in order to make thier little cabal plans. Could you imagine the scowl on her *cough*lovely*cough* face?

GENIUS!

[BiggestPOS]

These guys are brilliant. But what about the timing, or spacing between the "notes"? If I dial in a different rhythm is it the same?

A good use for copyright

[beretboy]

I forsee the following dialouge:

Me: hello?

Tele-solicitor: Hello would you like to buy-

Me: You have just infringed on national copyright hangup now or I will seize all your assets!

Tele-solicitor: *click*

Ah finally a good use for copyright :-)

Nice idea, but won't work

[Gorobei]

Copyright is concerned with COPYING work. It does not apply if someone else independently (usually defined as "was not exposed to your work") recreates the thing in question.

So, even if they have a phone number in their melody database, you don't infringe if you dial that number, because you created the melody independently.

Thats it, time to take action

[Seemlar]

So, who wants to help me encode all these 100,000,000,000 possible ringtones and put them on Morpheus?

Copyright does not squash other independant works

[rcw-home]

If a million monkeys type out the source code to MS Office, Microsoft can't sue. Likewise, if you happen to create a series of dual-tone meta frequency notes using a touch-tone phone using non-copyrighted material (a phone book, your memory, etc), then that's an independant creation. Now if a telemarketer overheard you dialing, and recorded it (made a copy), then you might have something.

IANAL (and I know the whole point was to be funny anyway).

STEP 1: Place hand 3 inches above head and 3 inches in front of head.
STEP 2: Briskly move hand from previous position to 3 inches above head and 6 inches behind head.

Re:And pulse too...

[AntiNorm]

I just copyrighted all the possible combinations of pulse dialing tones too... ahhahahahhah... you all owe me 0.05 cents per use... I'm rich!! I'm rich!!! ahaahhahahha

Just copyright all pulses, period. That way, for example, if someone causes a 500 Hz tone to be emitted, you'd be owed .05c * (500 Hz) = 25 cents per second. Not too bad if you ask me.

music, not number

[hagbard5235]

Ah... but they have not in fact copyrighted the
numbers. They have copyrighted the musical
representation of these numbers as DTMF tones.

Additionally, like hell numbers aren't copyrightable.
What do you think an mp3 file is? It's a very
large number. In fact EVERYTHING digital is a
number. So if you can't copyright a number, how
then is software, source code, digital music,
digital video copyrightable?

Re:Copyright does not squash other independant wor

[charon_on_acheron]

Actually, phone books are copyrighted. You can't legally copy lists of names and phone numbers from the phone book to make your own phone book for sale. Same for maps, which I always thought was the stupidest thing. A basic outline of the US is copyrighted. It is just a shape. A really bumpy shape. But if it is in a child's coloring book, it is copyrighted.

321-2333, not 312-2333

[dirtyhippie]

That's 321-2333, not 312-2333. Unfortunately, if you want to play the whole melody on the phone, there is no way to accurately represent the 5th (the 12th and 13th notes in the melody), but hitting 8 comes close since you hear (the 852Hz component of the 8 is heard as a fifth below the second, which is at 1336Hz - see the DTMF tutorial for where I got this info). Of course, its pointless for someone to waste their valuable time sitting there and trying to figure this stuff out like I just spent the last 20 minutes.

How close are they?

[Anonymous Coward]

People don't seem to have noticed that finicky little disclaimer under the score of their telephone number:
"Notation is an approximation only of the real pitch."
(See: http://www.magnus-opus.com/number_check.html)

The Equitempered Scale (or Equal Tempered Scale, depending on who you talk to) has pretty much been the standard for musical notes for the last 200 years, although the standard for A4 was only ratified as 440Hz in 1939.

The frequencies used for DTMF tones don't exactly match notes on the Equitempered Scale. I have tabulated the differences here:

Matching against the Equitempered scale:
(Based on http://hyperphysics.phy-astr.gsu.edu/hbase/music/e t.html#c2)
DTMF_tone Closest_Note %-error
697Hz F5, 698.46Hz +0.2095%
770Hz G5, 783.99Hz +1.8169%
852Hz G5#, 830.61Hz -2.5106%
941Hz A5#, 932.33Hz -0.9214%
1209Hz D6, 1174.6Hz -2.8453%
1336Hz E6, 1318.5Hz -1.3099%
1477Hz F6#, 1480.0Hz +0.2031%
1633Hz G6#, 1661.2Hz +1.7269%

As you can see, there are some considerable differences from a "purist" point of view.

This begs the question: Have the Magnus-Opus musicians actually copyrighted DTMF tone sequences, or just an approximation of them?

Another question worth asking: Even if the copyright holds-up, is it the end-users who are liable for infringement, or the Telco's who are on-selling the numbers as their own property?

Re:Copyright does not squash other independant wor

[wirefarm]

Map makers used to put in little false details here and there to make sure their maps weren't being copied. A street here or there that didn't exist in real life.
I always thought that was fiendishly clever.
I wonder if they still do it - I've always suspected that Montana doesn't really exist...

Re:Don't Check Your Number in their Database

[unitron]

If they keep a record of every time someone tests a valid number, they could sell that list to telemarketers at a pretty good price, as the list contains verified numbers of computer-owning housholds. With a con game like that, who needs copyrights?

Re:Copyright does not squash other independant wor

[lazytiger]

I can attest for sure, as a cartographer, that ALL map companies do in fact still produce inaccuracies, and quite intentionally. If you actually went to the trouble of comparing street maps to an orthorectified image (a.k.a., terraserver.com) of the same area, you would see that the map practically looks made up. Map companies, if they went to the trouble of checking, could easily tell if one of their maps had been copied. By the way, if you're looking for accurate maps to copy, USGS topo maps are far more accurate than any other maps available. They are made from the aforementioned orthophotos. And they are all in the public domain. They're not always up to date, however.

Worst Slashdot Lawyers Ever!

[Jerf]

I award this article the Worst Slashdot Lawyers Ever award. Not a single legally valid opinion is ranked above 3. Several utterly uninformed opinions are ranked at 4 or 5. Half the replies miss the point. Absolutely amazingly horrible. A record high noise/signal ratio. Wow.

Please for Gnu's sake don't whip off a letter to your Congresscritter based on this article; most posters have already looked stupid enough.

(Oh, in case you're wondering, the subject of this article is a funny-chortle, but no more. It has all the legal force of a Taliban edict in this country.)

How phone tones work

[image]

I wasn't sure what chords the phone tones actually were, so I went to over to howstuffworks and took a look. On page 2 of this article on telephones, it has a great section on the tones.

In particular, I learned that "the dial tone sound is simply a combination of 350 hertz tone and a 440 hertz tone," and "if the number is busy, you hear a busy signal that is made up of a 480 hertz and a 620 hertz tone, with a cycle of 1/2 second on and 1/2 second off" and there is a great chart showing the tone for each button on the keypad. For example, the tone for "1" is a combination of a 1209 Hz tone and a 697 Hz tone.

A little more research turned up this cool frequency to note converter and where I discovered that 1209 Hz is equivalent to D6 plus 50 cents, and 697 is F5 minus 4 cents. So basically the keypad one is an out of tune inversion of the D minor chord. (music majors feel free to Score: -1, Moronic)

Of course, if you were into phreaking then you'd already know all that.
