Embodiment Construction

[0025] In the following description, functions or constructions known to one of ordinary skill in the art will not be described in detail since they do not affect the description.

[0026] The description of the invention relates to an example of an audio-visual communication device SB utilized in the field of mobile telephony. The device SB is a cordless portable telephone, also called a mobile telephone. The mobile phone is a 2G+ or 3G mobile phone based on the 2G+ communication standard such as GPRS ("General Packet Radio System") or EDGE published by ETSI ("European Telecommunications Standards Institute") or the 3G communication standard. ("enhanced data rates for the development of Gsm"), said 3G communication standard is e.g. UMTS ("Universal Mobile Telecommunications System") or IMI- 2000 (“International Mobile Telecommunications”). These standards allow the existence of adequate data transfer rates and a high level of flexibility for multimedia communication by mean...

Abstract

The present invention relates to an audio-visual communication device (SB) and an associated method. Said audio-visual communication device has two reception paths, one video (VRP B) and one audio (ARP B), said paths being suitable for receiving a video signal (VS) and an audio signal (AS), respectively, originating from a second audio-visual communication device (SA). Said device is characterized in that it comprises means of return control (CNTRL) suitable for adapting an image frequency (FR) of said video signal (VS) as a function of a noise signal.

Description

technical field [0001] The present invention relates to an audio-visual communication device comprising an audio receiving path and a video receiving path adapted to respectively receive a video signal and an audio signal originating from a second audio-visual communication device. The invention also relates to a communication method suitable for said device. [0002] The invention finds particular application in the field of mobile telephony. Background technique [0003] The first edition of the journal "Wireless Communications and Mobile Computing", published in March 2001, discloses a communication device (in this case, a portable telephone currently referred to as a mobile phone) comprising a screen, a video camera and a wireless receiving module, the communication device permits communication with a second communication device via video teleconferencing. Teleconferencing via mobile phones is a service designated as a third-generation communication service, which is s...
