Home Theater Demo Disc - Version 2.0 - Page 6

There's nothing really to see at this point, the solution just has all of the assets brought in, put into clips and then put into streams. I haven't finished the menu nor began working on the navigation.

I've ran into a snag and am filling up the 16MB HDMV Menu buffer again, I have twice as many pages as with the first version and for some reason I thought I was well under half of the 16MB HDMV limitation then. Turns out with Version1.0 I was at 10 of the 16MB, so when I double that, well, It's obviously more than 16MB. Gotta reduce the size and I should be home free.

I believe I've solved it Leo, I just needed to take more stuff out of the IG layer and move it to the background (video) image. I haven't 100% verified it yet, but with a test I'm good. There shouldn't be a limit on the number of pages in an HDMV title, at least I don't see why. The bottleneck is likely the 16MB buffer.

Unfortunately you cannot just simply create another fresh menu and jump between them easily.

This disc has the following pages:

Auto - (This is a dummy page with an auto-action button for navigation coding)
Screen Type Selection
Widescreen Categories
Widescreen LFE
Widescreen Surround
Widescreen Visuals
Scope Categories
Scope LFE
Scope Surround
Scope Visuals

That's 10, hopefully there's no problem with 9 or more pages.

The buffer issue has nothing to do with the number of pages, buttons ect. It's simply a buffer for the graphics (IG layer) of the menus. My auto-action button is literally one black pixel, that is in the lower right corner of the screen and will be covered within the black bars of the widescreen/scope menu background. This auto action button, that resides in it's own menu-page is so virtually small I could probably build a million of these pages within a single HDMV menu. If I were you, I'd see if there is anything I can move from your individual buttons (N1: XXX, S1: XXX, A1: XXX) for each of your BOGs in each Page to a background layer. This will reduce the total IG size and will more than likely allow you to put all of your pages in one simple menu. This will ease the authoring side quite a bit.

For example, if you remember version1.0. On the right side of the menus is a transparent arc, on top of this arc is where all of the selectable items are. Up until now this transparent arc has resided in my IG, on each button, spliced accordingly. This caused the menu size to be larger than it needed because I just simply move that transparent arc to the background image (the image of my theater) so that the menu IG doesn't have to store that data for the graphics. I did this with Version1.0 because the arc was different between the category and clip selection screens. with Version2.0 the arc is exactly the same, so I'm pulling it from the menu IG. This reduced a single page from about 1.9MB to 0.7MB. Designer has a buffer checker, but from what I can see that is only for BD-J, which has a 45MB Buffer to work with.

You don't want to hop between menus, i.e. (One menu with 4 pages for widescreen and another separate menu with 4 pages for scope) because you then lose your ability to store register values. This is at least how I understand it. Not to mention the lag and delay, which is something I want to avoid.

The V1 Solution won't be of much help, because it won't show you the steps. What you need is a tutorial.

You have to have a normal image, as well as active and selected. All 3 states will be present at one time or another. If it's static text and simple an arrow that points at the static text indicating your selection, then the normal state needs to exist, just empty. The selected and active states can be the same, or different if you want confirmation after the button click. If you're doing animations, I will be of no help.

I assume you are building your menus in Photoshop and using Scenarist Designer.

I'll send you a PM.
