Silicon Valley startup Pulsent has claimed a new approach to video compression which breaks the technical barriers in delivering broadcast quality video over broadband networks.
The company said that its patent-pending technology provides a 400 per cent improvement in bandwidth and storage efficiency over existing block-based video compression techniques like MPEG-2.
Adityo Prakash, chief executive and co-founder of Pulsent, explained that the technology will provide the means for telcos and other service providers to deliver full screen, broadcast-quality video into the home at 1.1Mbps with the same resolution as TV pictures.
"The industry has long needed a fundamental rethinking of how video is processed and delivered to enable the next generation of services and applications. That is what we've achieved," said Prakash.
Pulsent is talking to major telecoms companies to license its technology for video-on-demand, cable programming and internet access over DSL line services.
The technology identifies structural elements and objects in any video scene and models their motion. The objects are the natural, elastic components of any image and directly correspond to parts of real-world objects, the company explained.
Due to be demonstrated at the National Association of Broadcasters convention next month, the system will enable the development of new applications and products that benefit from object manipulation.
Pulsent also intends to work on technology to solve internet video delivery problems such as packet loss, congestion and buffering.
Microsoft, RealNetworks and others also expect to deliver broadcast quality programming over the internet.
