ALADIN - Streaming Server
ALADIN is the mobile extension of the CYBERLOUNGE project, developed in Ubiquitous Computing Class 2003 (http://isnm.de/cyberlounge) User's are equipped with mobile devices, that are able to scan their location by using Infrared and Bluetooth location tracking techniques. A PC/laptop version using RFID labels and Infrared will be also available. Users have to register at the device using biometic access methods (in our case we use a PDA with inbuilt fingerprint scanner). Also objects can be identified using RFID labels. This context information (user, location, objects) triggers a list of context-based services to be available. These services can be customized and tailored to the specific needs and requirements of the respective context spot. |
Participants of this class have specified, designed and implemented a streaming server for the ALADIN project. Audio and video files for the ALADIN services as well as film clips for the 'Digital Film and Video Development Class' are supported by a Helix Streaming Server installation. For this purpose, scripts have been provided to transform the raw video material. Beside a 90° rotation to support the landscape display, the size has been reduced to the display resolution of 320*240 pixel and the video has been compressed into different datarate parameters. |
