NECTAR :: Theme 3
This project involves the creation of an interactive slide adaptation system. The system uses a web browser as the client display software. Interactivity is provided through user activated hyperlinks which are used to retrieve and expand content on-demand.
A novel summarization scheme is proposed which combines information from multiple sources such as audio data and presentation slides to improve accessibility of presentation archives for users.
A demonstration of time stretching an audio signal, i.e. changing the playback speed without altering the pitch of the signal.
A database-driven transcoding engine which transcodes video content and manipulates the ePresence screen-layout based on received metadata (e.g., client preferences and capabilities, communication channel properties, etc.).
System for transcoding encrypted multimedia content (video, audio, slides, etc.) without requiring decryption. Full scalability can be achieved while maintaining end-to-end security. Current focus is on scaling encrypted MPEG-4 video stream.
Shape-Adaptive Image Coding
A codec for compressing arbitrarily-shaped still visual objects in support of application-driven transcoding.
