Video accompanying the paper "Middleware Support for Seamless Multimedia Home Entertainment for Mobile Users and Heterogeneous Environments" (July 2003) demonstrating the handover of MP3 audio playback from a Linux PDA to a stationary Linux-PC (the Multimedia-Box) and back to the PDA. This whole application scenario is realized using the Network-Integrated Multimedia Middleware (NMM).

Audio file accompanying the paper "Dynamic Distributed Multimedia: Seamless Sharing and Reconfiguration of Multimedia Flow Graphs": This audio file demonstrates a synchronized continuous session handover: active parts of a flow graph for decoding and playback of audio data are moved to a different host during runtime while keeping the playback continous and synchronized. For demonstration purposes, the playback is then performed on both hosts simultaneously.
For measuring a possible offset between the two audio streams during handover, we recorded the audio output of the two systems involved: from both systems, we recorded the same stereo channel as the left respectively the right channel of the stereo input of a third system. We found that the offset between the two streams typically is in the range of 1-2 milliseconds.
  • handover.wav, 5.5 MB; demonstrates three handovers: the left channel is taken from the systems that initiates the handover, the right channel is recorded from the system to which the handover is performed.


We presented our Network integrated Multimedia Middleware at the 1st Saarbrücker IT-Dialog Automotive Saar and highlited the possibilities to easily realize a car infotainment system based on our software with sophisticated services, like audio handover. The following pictures show audio handover between a PDA and our car infotainment system, which is simulated by a Laptop. The Laptop is integrated in a movable wall that shows the cockpit of a VW Beetle and the display of the Laptop.
