Abstract: A method for video teleconferencing comprises receiving a starting image with a number of rows and a number of columns. The starting image is downscaled with a dual-axis warping function to create a scaled image with a number of rows fewer than the number of rows of the starting image and a number of columns fewer than the number of columns in the starting image. Then, a transmission image is created from the scaled image.

Abstract: A system teleconferences first and second speakers in first and second connected remote teleconference sites. Each teleconference site includes corresponding transceivers to transmit and receive electronic signals. First and second acquirers are configured to acquire an image of the first and second speakers, and to generate the electronic signals based on the acquired image. First and second remote image displays process the electronic signals to display the image of the remote speaker. The first remote image display includes a processor with a screen to display the image of the remote speaker. The first acquirer is adjacent the screen, so the acquired image of the first speaker, while looking at the image of the second speaker, is similar to an image acquired if the first speaker would look at the first acquirer. The second display includes a displaying screen suitable to contain an image projected life-size of the first speaker.

Abstract: The technology disclosed further relates to distribution of live streaming sources during a video collaboration session. In particular, it relates to receiving or placing an outside call from or to at least one remote limited participant to be joined with an ongoing video collaboration session on a display wall that combines multiple live streaming sources, locating a template that identifies at least one live streaming source selected from the ongoing video collaboration session to transmit to the remote limited participant, and causing a copy of the selected live streaming source to be directed to the remote limited participant upon connection to the ongoing video collaboration session.

Abstract: A processing method and device for packet loss compensation in video-conferencing system are provided. The method includes: when a video conference is held, judging whether terminals participating in the video conference include one or more FEC terminals, if yes, matching code stream processing capabilities of transmitting terminal and receiving terminal between FEC terminals which transmit a code stream or between an FEC terminal and an ordinary terminal which transmit code stream, and converting a data code stream transmission rate of the transmitting terminal into a bearable data code stream rate of the receiving terminal. The device includes a judgment component and a matching component. The solution enables a terminal with packet loss to activate an FEC function to compensate lost data, and also enables an ordinary terminal without packet loss to keep an original data code stream rate for communication, thereby maximally ensuring the image quality of the video-conferencing system.
