what's different between BuildPipeline.BuildPlayer and BuildPipeline.BuildStreamedSceneAssetBundle?

Thanks!!

BuildPlayer (Unity Pro Only) - Allows the user to build out the player programmatically instead of through the build menu options under file. The output of this will be a unity3d file and some wrapper for it’s execution. If you build a webplayer, you will have an html file to execute it, etc, etc.

BuildPlayer API

BuildStreamedSceneAssetBundle - Allows you to build an asset bundle, scenes are available to the calling unity application after the asset is downloaded(or streamed) and assetBundle is called on the WWW object that downloaded it. This will output a unity3d file that contains compressed assets.
