New Technologies in Multimedia

Fully Configurable Video Coding

Personnel: Professor Iain Richardson
Dr. Sampath Kannangara

We propose a new video coding paradigm, namely fully configurable video coding. This radical new approach has the potential to dramatically improve compression efficiency and image quality and will enable new ideas and technologies to be implemented rapidly and flexibly. It opens up exciting new challenges for video compression research and offers significant potential benefits to a wide range of video-based applications. In the new paradigm, a universal decoder can be configured as any standard-based or proprietary design of video decoder, without downloading new software. The universal decoder can be re-designed during decoding, adapting its configuration to maximise video compression performance. This will be achieved by specifying new or changed video coding functions at the encoder, communicating these changes to the decoder, creating them in the decoder and carrying on with decoding using the new functions.

This work will establish a framework for Fully Configurable Video Coding and will demonstrate adaptation, communication and instantiation of decoding structures in a prototype fully-configurable video codec.
