Using
Meta Data information representing objects motion images and video can be
efficiently compressed to maximise bandwidth use while maintaining
quality
The
Technology
Efficient use of bandwidth in ever increasingly detailed video streams is
a key driver for compression of video. The technology developed at UNSW is based
on the JSIV (Jpeg2000 scalable interactive video) system and uses motion meta
data to ensure a highly efficient compression focussing detail on objects of
interest. This combination system allows for more efficient bandwidth use and
image quality maintenance upon video retrieval and scaling.
The technology can be adapted in areas where remote interactive browsing
is useful. This may include: streaming, conferencing, surveillance and
broadcasting. Currently researchers have developed a demonstration software
prototype of the system which demonstrates JSIV with explicit motion. This may
be used to benchmark the capabilities of the technique or could be developed
further into a product.
Key
Benefits
- Application of motion and disparity data in interactive
video
- Use of a variety of metadata to allow client reconstruction of images
with more efficient bandwidth usage and minimal quality
loss
- Efficient transmission/use of wide field surveillance imagery with
emphasis of detail on areas of motion.
Applications
- Surveillance and security monitoring
services/technologies
- military/security video streaming
applications
- Online Video streaming services
The
Opportunity
NewSouth Innovations is currently looking for partners to licence the
technologies developed by Prof David Taubman, the inventor of the successful
Kakadu Software JPEG2000 compression SDK. Due to the similarities across the
portfolio these technologies are available as a group or individually for use in
potential licensee’s commercial products.
