subtitle question

just a quick one. if i have
[71 00 00 0E 00 45 00 00] Set gprm(14) =(mov) 69
and then
[41 00 00 00 8E 00 00 00] (SetSTN) Set Sub-picture stream = gprm(14)

what exactly do i get in the end? i mean, which subtitle number this selects? according to dvd shrink list, this would select subtitle #6. so when using SetSTN with gprm, gprms are starting from 64 for first subtitle stream? can someone confirm this?

gprm(14) will be assigned the decimal value of 69

[41 00 00 00 8E 00 00 00] (SetSTN) Set Sub-picture stream = gprm(14)
sprm(2) will now be assigned the decimal value of grpm(14) so sprm(2) = 69

Subtitle #6

DVD Shrink is correct and you are also too for the starting 64 value. Also if sprm(2) = 0 then no subtitles will display.

OK. confirmed.

@2COOL - Bit confused here.

I thought SPRM(2) has to be 62 (and then add 128) (ie 0xBE) to be off?

I was working on a DVD earlier with a subtitle menu with 4 options

Subp 1: English
Code:
[51 04 00 00 C0 00 00 09]  (SetSTN) Set Sub-picture stream = 0, on ; LinkPGCN PGC 9
Subp 2: French
Code:
[51 04 00 00 C1 00 00 09]  (SetSTN) Set Sub-picture stream = 1, on ; LinkPGCN PGC 9
Subp 3: Espanol
Code:
[51 04 00 00 C2 00 00 09]  (SetSTN) Set Sub-picture stream = 2, on ; LinkPGCN PGC 9
None

Upon viewing the sprm(2) after selection...

English > sprm(2)= 64
French > sprm(2) = 65
Espanol > sprm(2) = 66
None > sprm(2) = 0

I tested other DVDs other and yielded the same results.

So why is this the command to turn all subbies off?

Code:
[51 00 00 00 BE 00 00 00]   7  (SetSTN) Set Sub-picture stream = 62:none
Regards

You are right. sprm(2)=62 can also turn off subtitles. I found in my testings that if no selection is made in the subtitle menu, sprm(2) will hold a value of 0 during Title play. By default, sprm(2) should be 0 upon DVD insert.

Edit: hmmm...let me get back to you on sprm(2). I'll see if I can get a reference.

Update: Default sprm(2) is 62.

In SetSTN, the value you use is the number of the subtitle (ie 0 to 31, or 62 for none selected, or 63 for forced) + 0x40 to turn the subtitle ON.
You MUST also set the bit 7 (0x80) to instruct SetSTN to change the subtitle assignment.
Valid values are therefore:
128 to 159: Select subtitle 0-31 but don't turn it on.
192 to 223: Select subtitle 0-31, and turn it on.
190: Don't select any subtitle (leave the player decide)
255: Set forced subtitle

When playing, the SPRM 2 will hold the same value ORed with 0x7F (ie, bit 7 is turned off):
0 to 31: Subtitle 0-31 selected but not displayed.
64 to 95: Subtitle 0-31 displayed.
62: Player decide.
127: Forced subtitle.

The value 69 is therefore: Subtitle 5 displayed.

Here were mpucoder's thoughts:

Stream 31 is not "off", it is just very unlikely that it will be present. There can be as many as 32 subpicture streams, numbered from 0 to 31 (0x00 to 0x1f, or substream numbers 0x20 to 0x3f). The designation for "off" is stream 62 (ox3e, combined with the required flag to cause the new value to be stored is 0xbe).
I know IfoEdit is messed up in its interpretation, and we had a long thread about the values. Since that was awhile ago, it bears repeating.
value meaning
00-7f will do nothing, bit 7 must be set to cause any change
80-9f stream 0 to 31 selected, but off
a0-bd meaningless
be no subpicture
bf stream 0 forced, but off - ie, invalid
c0-df stream 0 to 31 selected and displayed
e0-fe meaningless
ff stream 0 forced and displayed.

Yes, except for 62. You have said "let the player decide" while mpucoder has said "no subbie".

He is right... and wrong. When 'not set', the player may take the decision to select and turn on a subpic, based on the user's preferences. This is why it is best to use a stream explicitely turned off (values 128 to 159) to be sure the player won't select one.

[51 00 00 00 FF 00 00 00]  (SetSTN) Set Sub-picture stream = 63:forced sprm(2) = 127

You must turn the forced subpic ON, so last line should be:

[51 00 00 00 FF 00 00 00] (SetSTN) Set Sub-picture stream = 63:forced sprm(2) = 127

Ooop!. Everything is correct now and can be used as a solid reference. thanks again r0lZ! I was meaning to document that for a long time now. It just keeps getting bump down my TODO list.

@rolz

Does this mean that we want the forced stream on in every instance?

By forced stream, I understand this to mean, the occasional subtitles that display (such as the Japanese subbies in Kill Bill 1?) as opposed to the full dialogue. Is this correct?

I feel like I'm 0-2 now but here is goes.
Code:
[51 00 00 00 FF 00 00 00]  (SetSTN) Set Sub-picture stream = 63:forced sprm(2) = 127
This will only force subpicture 0. It's actually the first subpicture. Can't confirm with Kill Bill 1 but the Japanese subs aren't Subp 0, then it won't show them. I hope I read your question right.
