DoStudio Authoring basics
DoStudio Authoring replaces the complexity of the Blu-ray Disc™ specification with simple to understand
concepts that any DVD author can learn quickly. This section briefly explains the concepts and terminology
that are essential to working with DoStudio Authoring successfully.
Menu elements
Let's begin with the elements that comprise a pop-up menu. When building menus in DoStudio Authoring,
you will be working with three basic elements: menu blocks, sets, and buttons.
Menu blocks
Menu blocks are rectangular areas of the screen, defined by you, the author, that contain a menu such as
your main menu, or a submenu such as a menu for chapter selection or special features. DoStudio
Authoring can accommodate 32-bit graphics for your menus (HDMV-only tools can accept only 8-bit
graphics). Menu blocks cannot overlap on screen. They typically have a background image that defines the
block's size on the screen; however, menu blocks can be transparent. You can create as many menu blocks
as your project requires.
By default, the menu block that is listed at the top of your project's menu tree is the menu block that is
associated with the pop-up menu button on the Blu-ray Disc player's remote control. In other words, it will
toggle on and off screen when the viewer presses the pop-up menu button. You can change which menu
block is associated with the pop-up menu button using actions, so you can program your disc to display a
different pop-up menu depending on what part of the disc is playing.
Menu blocks can animate on and off screen. They can float, or "pop up," over your video while it is playing.
Menu blocks are the parent element of a menu. This means that any other menu elements live inside them
and are attached to them. When you delete a menu block, any sets or buttons contained in that menu
