US 2015/0092013 A1 · METHOD AND A DEVICE FOR TRANSMITTING AT LEAST A PORTION OF A SIGNAL DURING A VIDEO CONFERENCE SESSION

Abstract

A method and a device for transmitting at least a portion of a signal during a video conference session is disclosed. In one aspect, a method of transmitting at least a portion of a signal acquired by a first terminal to one second terminal during a video conference session, the signal comprising an audio stream and a video stream conveying images acquired with the help of one video image sensor is disclosed. The method comprises obtaining a parameter representative of a quality of the acquisition performed by the sensor of the video images conveyed by the video stream of the signal, and a process of notifying the first terminal of information representative of the acquisition quality. If this parameter is representative of an acquisition quality that is higher than a predetermined level, both the audio stream and the video stream of the signal are transmitted to the second terminal. Otherwise, the audio stream is transmitted to the second terminal and the video stream is blocked so that it is not transmitted to the second terminal.

Dependent claims

A method of transmitting at least a portion of a signal acquired by a first terminal to at least one second terminal during a video conference session, said signal comprising an audio stream and a video stream conveying video images acquired with the help of at least one video image sensor associated with the first terminal, said transmission method comprising:

a parameter-obtaining process for obtaining a parameter representative of a quality of the acquisition performed by the sensor of the video images conveyed by the video stream of the signal;
a notifying process for notifying the first terminal of at least one item of information representative of the acquisition quality of the video images conveyed by the video stream, said representative information enabling a user of said first terminal to take corrective action seeking to improve the acquisition quality of the video images by said sensor;
and
if this parameter is representative of an acquisition quality that is higher than a predetermined quality level, a process of transmitting both the audio stream and the video stream of the signal to said at least one second terminal;
or else:
a process of transmitting the audio stream to said at least one second terminal;
and
a process of blocking the video stream so that the video stream is not transmitted to said at least one second terminal.

a module for obtaining a parameter representative of a quality of the acquisition performed by the sensor of the video images conveyed by the video stream of the signal;
a module for notifying the first terminal of at least one item of information representative of the acquisition quality of the video images conveyed by the video stream, said representative information enabling a user of said first terminal to take corrective action seeking to improve the acquisition quality of the video images by said sensor;
a module for transmitting both the audio stream and the video stream of the signal to said at least one second terminal, which module is activated if the parameter is representative of an acquisition quality greater than a predetermined quality level;
and
said device being suitable for activating, when said parameter is representative of an acquisition quality that is not greater than said predetermined quality level:
a module for transmitting the audio stream to said at least one second terminal;
and
