Abstract: The present invention discloses an arrangement and a method of localizing active speakers in a video conference. According to a preferred embodiment of the invention, a localization device locates one or more microphones relative to the camera, while the microphone(s) in turn localize the audio source relative to their own position(s). As the microphone(s) is/are usually positioned close to the audio source in a video conference, the ratio of the distance between microphones (or microphone elements) relative to the distance between table microphone and audio source is reduced. Thus, the microphone(s) is/are able to determine the position of the audio source with a higher resolution than if placed close to the camera. When the respective positions of the microphone(s) relative to the camera and the audio source are known, the position of the audio source relative to the camera is then determined by means of geometrical calculations.

Abstract: The present invention discloses an improved audio echo canceller processing echo, noise and near end talk in a narrower, but still intelligible, frequency band for reducing required processing power and complexity. In a preferred embodiment of the present invention, an input audio signal of captured sound in an audio communication system is decimated and then divided into a number of sub bands by an analyse filter. Each sub band is processed as in conventional audio echo cancelling by subtracting the signal with an echo estimate from a model of the acoustic signal in the respective sub band, except from that the signal is also bypassed, adjusted by an filter and subtracted from the processed signal. The resulting signals are then recombined by a synthesise filter and interpolated to the original sampling rate and bandwidth. Finally, the output from the synthesize filter is added to the input audio signal, which has been delayed and adjusted by an filter. The filters are controlled by an control algorithm detecting the presence of near end sound, far end sound and noise, so that the filters, and consequently the high pass filter of the echo canceller, only pass high frequency (above low pass frequencies) in cases where only near end sound is detected.

Abstract: A method in a video conferencing device for filtering media packets from a video conferencing data stream. The video conferencing device comprises a media processing network, a general purpose network, a soft-core processor, a Look-up Table memory (LUT), and a full network stack. The method comprises receiving at the soft-core processor a packet of a video conferencing media stream, determining whether the length of the packet is sufficiently long to contain media, determining whether the protocol of the packet is supported by the soft-core processor, finding a media stream ID for the packet, sending a request to the LUT using the stream ID as an input value while in parallel determining whether the packet is a valid media packet; and when receiving an destination address in the media processing network from the LUT and determining that the packet is a valid media packet, modifying the header of the packet with the destination address received from the LUT; and routing the packet to the modified destination address. A video conferencing device is adapted to perform the method.

Abstract: Different sampling rates between a playout unit and a capture unit are compensated for. The playout unit receives samples from a computational unit, and the capture unit sends samples to the computational unit. A playout fifo buffer operates in a playout time domain, and a capture fifo buffer operates in a capture time domain. The computational unit is synchronized to a common clock. A first relationship is calculated between the common clock and a playout fifo buffer read pointer, and a second relationship is calculated between the common clock and a capture fifo buffer write pointer. For each sample in the playout time domain a corresponding sample in the samples from said computational unit is found and sent to the playout fifo buffer. For each sample in the common clock time domain the corresponding sample in the capture time domain is found and sent to the computational unit.
