Assigning region
From A-SMIL.org
The <region>
tag defines a screen layout where individual media items can be assigned to play. Media objects can then be assigned to each defined region.
<smil> <head> <layout> <root-layout width="1280" height="720" /> <region regionName="video" top="0" left="0" width="720" height="480" z-index="1" /> <region regionName="slideshow" top="0" left="720" width="560" height="480" z-index="1" /> <region regionName="overlay" top="50" left="50" width="100" height="100" z-index="2" /> </layout> </head> <body> <par> <video src="ad1.mpg" region="video" /> <img src="ad2.jpg" region="slideshow" /> <img src="logo.png" mediaOpacity="50%" region="overlay" /> </par> </body> </smil>
The <head>
section defines a typical 3-zone digital signage application with a zone for 720x480 video, a slide show zone, and a ticker zone. Overlaying the video zone is an overlay layer which allows the user to place a logo or a dynamic message on-top of the running video.
The <body>
section contains contents to play in parallel in all four regions defined.
