Patent number: 9525569Abstract: A terminal for transmitting a voice signal, comprising: a transmitter having a first transmission module arranged to transmit signals over a packet-switched data network and a second transmission module arranged to transmit signals over a circuit-switched telephony network; a microphone for generating a voice signal; and signal processing apparatus configured to generate a first signal and a second signal from the voice signal, each representing information from the voice signal over a same portion of time. The signal processing apparatus is further configured to supply the first signal to the first transmission module for transmission to a receiver via the packet-switched data network, and to supply the second signal to the second transmission module for transmission to the receiver via the circuit-switched telephony network. There is also provided a terminal for receiving such signals and reconstructing the voice signal, and corresponding methods and program products.Type: GrantFiled: March 3, 2010Date of Patent: December 20, 2016Assignee: SkypeInventors: Jan Plasberg, Koen Vos

Publication number: 20140362291Abstract: Method, apparatus and computer program product for processing a video signal, the video signal comprising a plurality of frames, wherein the frames of the video signal are received at a jitter buffer, and the frames are output from the jitter buffer at a variable output rate to account for jitter in the received frames. Variations in the output rate are controlled in dependence upon the visual information content of the video signal, the visual information content of the video signal being the portion of the video signal that is to be displayed when the video signal is played out.Type: ApplicationFiled: August 25, 2014Publication date: December 11, 2014Inventors: Jan Plasberg, Andrei Jefremov

Publication number: 20110134911Abstract: A method, terminal and program for making a call in a packet switched network between a calling device and a called device. The method comprises receiving at a processor of the calling device samples of a speech signal and an identity of the called device, executing code on the processor to perform the steps of: determining based on the identity of the called device whether a filter should be applied to the samples, when it is determined that a filter should be applied, filtering the samples, and encoding the filtered samples for transmission on the packet switched network.Type: ApplicationFiled: June 23, 2010Publication date: June 9, 2011Applicant: Skype LimitedInventors: Mattias Nilsson, Stefan Strommer, Jan Plasberg
