Understanding the files on the DVD of Arirang Karaoke (hk2 & midi0)

Here is the English song book for Arirang DVD Vol 31 in Excel format :

By the way, does anyone know what program is used to produce a Midi Karaoke DVD like that?

[bigboss97]

When I searched for "your" I found:


For "madonna":


But strange, that I can't find anything for "beatles","elvis".
Why only those few songs? If they are compressed they all shouldn't be readable.

Speculations :-)
1) here's a dynamic mask which "rotates" and plain text only appears accidentally at certain rotation.
2) The mask is based on the song number or title. All these readable songs have a common charater.
3) They are not compressed. Otherwise all should be unreadable.

Just an update:

Trying to get the best tool.

[bigboss97]

Based on the fact, that some lyrics have upper and lower case reversed. In order to reverse this, a 0x20 mask is required. After analysis of some blocks (based on "OK") I found the mask  It's 4 bytes before the text starts:


It's only a single byte mask which is much simpler than California Electronics.

Do to:
Find the offset of a song. It could be in the index file.

2 of those 4 bytes could the the length of the lyrics:

I still can't figure out how to associate the song ID from MASECOS4.IDX to the data in MULTAK. Any one can help?
I also tried in SEARCH1.IDX, no success  :-(

Alternatively, we can search for "OK" (start of a data block). I know that the first song in MULTAK is 20001. I simply count from there. But there's a risk that there are jumps in song numbers. So, the original song ID's won't match my count. Also, I need to identify the first song of each language because there's a jump in song number.

That's a very "dirty" solution. But if we can't read the address table I think that's the only way. Any suggestion?

[bigboss97]

It's obvious that from 0xd20 there's a table. But there's no direct link to the offset of each song. Since we know the size of a song block (based on "OK") I calculated the difference between 2 values. I took the result and times 8. Then we can see it's almost exactly the size of the blocks:



1) Ignore the first 2 songs. This table must be referring to the offset of each song.
2) There are recurring huge jumps, e.g. 20009. When do they occur?
3) 20013 & 20014 look more like corrupt data. But if that's the case these 2 songs should fail on the player?

To do:
Find out the pattern of the jumps. Then we can get to the offset of each song.

[bigboss97]

I use the 2 MSB bytes seperately and multiply with 0x4b00. Besides the first 2 songs, the new algorithm seems to be handling the jumps well

[bigboss97]

I think that I've got the table read correctly. The list is created by reading the header information of each data block in MULTAK. Although there are craps in the middle it has read up to 6000 records without crash.

I guess that the address table also refers to the next big file. But I'll start looking into details in each block. I think that 6000 songs should be enough for experimenting.

I'll post the source codes later. Unless someone want to see the current codes.

Ari2Midi.zip

The lyrics should be read in the same way.

I still haven't found a way to read the MIDI data. I've tried to read the section after the lyrics according to:
http://board.midibuddy.net/showpost.php?p=533722&postcount=31

which was used in California as well. I can't see any 5 bytes pattern:

[bigboss97]

Since we don't know the start of the MIDI part we need to do some experiments. I'm going to run the CalElect MIDI routine on the data. In order to get the best chance to read the MIDI correctly, I've picked the shortest song (from 5000).

mask.zip

[bigboss97]

This routine will "cut" the shortest song from 1000 songs (starting at the given song number). Two files are written, one raw and one masked. Hopefully, this can help further analysis.

P.S. The number in the output file names is not the song number.

Can anyone see any MIDI data?

Hi, can you help me to get the Korean list song also please, I really have no idea how to work with the DVD. I really appreciate your help. Thanks

[bigboss97]

See:

I don't know what code is used. It's not unicode, i.e. you won't be able to read it on English XP. You might be able to read it on Korean XP.

[bigboss97]

I have updated my list generator and created two Chinese song lists. It seems that vol.34 has less Chinese songs than vol.31, is that true?

Found this forum after googled HOTDOG30.dat

Registered just to say: Your work is impressive!!!
Now trying to understand your code, especially the midi and lyrics parts :)

[bigboss97]

Welcome to forum.

Since you were searching for HOTDOG file I assume that you are using California player, right? That one is basically done, at least for 2 DVD's of different versions.

In Arirang, I couldn't progress further. The lyrics part is half way done. But no progress in MIDI at all although (I believe) the MIDI is not that hidden as the lyrics, because normal eyes won't be able to read MIDI data. So, I guess the same mask is applied to the MIDI part. Unfortunately, I still can't read it.

Currently, I don't have access to Arirang player. Without patching the data I have no chance  :-( Even the analysis of patching MIDI data would be hard enough. If you can help with the MIDI part that would be great. Get the latest source code. It allows you to extract a section of data of one song.
