Video bit stream highlighting method for transmitting stream to videoconference participants, involves adjusting value of encoding quality parameter of video bit stream based on measured value of predefined parameter of audio bit stream

摘要

The method involves measuring a value of a predefined parameter of an audio bit stream (aA-aC). A value of an encoding quality parameter of a video bit stream (vA-vC) is adjusted based on the measured value of the predefined parameter, to encode the video bit stream. The quality parameter has an encoded video bit stream rate, a redundancy rate in video bit stream transmission and a number of images per time unit of the video stream. Independent claims are also included for the following: (A) a method for encoding and transmitting video bit streams to several participants of a videoconference (B) a software module having instructions for highlighting a video bit stream associated to an audio bit stream (C) a videoconferencing bridge for encoding and transmitting a video bit stream to participants of videoconference and having a video bit stream highlighting device.
