Media Player. To play the media files PlayBOX can use almost any existing media player on the market. Most of these are freeware or Open Source. Per default PlayBOX is configured to use Winamp (xxx.xxxxxx.xxx) on Windows, AlsaPlayer (xxx.xxxxxxxxxx.xxx) on Linux and iTunes (xxx.xxxxx.xxx/xxxxxx) on Mac OS x. The user will only be able to see the player if the PlayBOX back-end and front-end run on the same pc. But PlayBOX provides visual feedback in the user’s browser about current track and playlist along with the familiar »VCR buttons« (play, pause, stop, next, previous, rewind and fast forward). Code Structure The code is extremely well-structured and well-written. It utilizes PHP’s object oriented capabilities and a layering scheme to make code maintenance and extension very straightforward. The code is divided into 3 layers: The Business Logic layer is where all data structures are manipulated, the database is interacted with and files are managed. The code in this layer has no knowledge about presenting the data. The Utility layer »asks« the objects in the Business Logic layer about the data and prepares html and variables for the Presentation layer. The Presentation layer is almost 100% html, CSS (Cascading Style Sheets) and graphics (gif and jpeg). Dynamic data in this layer is retrieved from the Utility and Business Logic layers using PHP tags, and simple PHP loop structures can be used to present variable length lists etc. If a new platform – PDA, WAP, Series 60 or any other platform that requires specific presentation – must be supported, only the presentation layer needs to be written, cutting off more than two thirds of the development time. All formatting is done with CSS, separated in a folder that serves as a »theme«. Giving PlayBOX a whole new appearance is just a matter of making a new theme by changing the desired graphics and CSS files. This is also how PlayBOX branding is done.
