 The prototype will be a new platform that enables the capture, mixing, filtering, analysis, recording and streaming of teleimmersive 4D audio-visual data in a real-time, modular and flexible manner so that individual data sources or algorithms can be replaced or evolved in the future. The key features are therefore:
 
 * **F1:** *Generation* - Scene reconstruction from fixed lab spaces as a 4D-AV data source 
-* **F2:** *Mixing* - 4D-AV mixing and filtering system, from any number of arbitrary data sources
+* **F2:** *Transformation* - 4D-AV mixing and filtering system, from any number of arbitrary data sources
 * **F3:** *Analysis* - 4D-AV Analysis system to extract and embed higher-level data about a scene
 * **F4:** *Recording* - 4D-AV recording and playback as a generic 4D-AV data source
 * **F5:** *Streaming* - Lossless and lossy compression of 4D-AV for storage and streaming
