Patent for License with Right to Enforce:

Silence-based Real Time Voice /Video Transmission    

A methods and systems of silence-based adaptive real-time voice and video communication over the Internet.

Overview

It provides a method of real-time voice and video transmission using silent periods and talk-spurt characteristics of conversational speech. If silence in the sending or receiving voice stream has been detected, it aggressively transmits the corresponding key frames of the video stream adaptively.

The proposed adaptive transmission of real-time voice and video streams that takes into account the on-off patterns in conversational speech provides good quality of voice stream when a real-time video stream is introduced.

Primary Application of the Technology

The invented methods and systems could be used for Video and Voice over IP applications over the Internet.
