Abstract: A system and method for performing echo suppression on a server in browser-based online audio conferences without downloading or installing software on a participant's computing device is disclosed. Streams of audio communication data from the participants in an audio conference are received at the server. An echo suppression application determines the first party that speaks by analyzing the streams to locate speech data, and assigns that party as the “owner” of the audio channel. The speech data is sent to the other participants in the conference. The application then determines whether newly received audio from the owner of the channel is new speech; if so, then the party remains the owner of the channel, and the new speech data is also sent to the other parties in the conference. The channel is surrendered if no new speech is received from the owner in a defined period, and the next party that speaks becomes the new owner of the channel. The other audio data from the participants is replaced by silence.

According to one such implementation, a method is implemented for encoding a sequence of images. A plurality of orthogonal transforms is implemented on a set of N images, where N is greater than one. The images are linked by motion fields that include sets of respective portions of the images. In particular, the construction of a motion-compensated orthogonal transform is accomplished for the important case where at least one portion of any of the N images—or any part of this portion—is used more than once to motion-compensate other portions of the N images—or parts thereof.

Abstract: A method is disclosed for decomposing a set of even and odd pictures into low-band and high-band pictures respectively in a image decomposing unit, in which the even picture is used by at least two prediction motion compensators on which the output signal of each prediction motion compensator is scaled according to the number of prediction motion compensators. The method includes calculating the high-band picture by subtracting from the odd picture the scaled motion-compensated signals and using the high-band picture in the at least two update motion compensators, the output signal of each update motion compensator being scaled according to the number of update motion compensators. Finally, the low-band picture is calculated by adding the scaled update motion-compensated signals to the even picture.
