Method for real-time broadcasting of multimedia files during a videoconference, without interrupting communication, and man-machine interface therefor

Abstract: The invention concerns a method of broadcasting data files, in particular multimedia files, during a video conference using a sending terminal and a man/machine interface located in the said terminal. According to the method proposed, the broadcasting of the files is effected in real time with a current video conference communication, without breaking this communication, using the audio and video channels open for this communication, a participant being able, using the said terminal, by means of a simple selection of the file appearing on his screen and movement of this, to activate the launch of the broadcasting of the file to be broadcast.

Process for the transmission and reception of conditional access programs controlled by the same operator

Abstract: Process for the transmission and reception of conditional access programs controlled by the same operator. According to the invention, specific check words (MCSi) are formed for various programs of the same operator from a root check word individual to said operator. The check words of the access titles include a part which is common to all the programs controlled by the same operator and a part which is specific to each program. Uses in television, radio, data transmission, messaging, etc.

Reconfigurable device for insertion-extraction of wavelengths

Abstract: This device includes optical add-drop multiplexers (M1 to M2) each having a band-pass filter. An optical switch (C1) has outputs connected to the multiplexers. An optical coupling (C2) has inputs connected to the multiplexers. The device is useful in optical communications.

Automated test generation from SDL specifications.

Abstract: Automated test generation from formal specifications presents a lot of promises, either in cost control or test suite correctness Some interesting tools begin to emerge, either prototypes or industrial strength tools We present the result of the integration in ObjectGEODE of an industrial test generation tool 1 This tool is based on two complementary test generation prototypes, TVEDA and TGV TVEDA comes from the research laboratory France-Telecom-CNET, it provides for test purposes and test case generation, based on state space exploration combined with heuristics TGV has been designed in the research laboratories Irisa and Verimag, it provides test case generation based on efficient, on-the-fly state space exploration techniques

Optimized Rate-Distortion Extraction with Quality Layers

Abstract: In this paper, we present the concept of quality layers that has been introduced in scalable video coding (SVC) amendment of MPEG4-AVC. The quality layers are used to evaluate and signal the impact on rate and distortion of the various enhancement information pieces. Using this quality layers information allows to gain up to 0.5 dB with respect to the basic standard software verification model (SVM) extractor that was proposed initially in SVC. Thanks to the signaling of this information in the header of the network abstraction layer (NAL) units, the rate adaptation can be performed with a simple parser, e.g. for rate adaptation in an intelligent network node.
