Abstract: A communication device (12), computer readable medium and method for synchronizing video data with audio data received by a communication device, the video data including a plurality of segments of video data and the audio data including a plurality of segments of audio data. The method includes receiving a first segment of audio data at the communication device (12); receiving a first segment of video data at the communication device, at the same time or later in time than the first segment of audio data, the first segment of video data being logically related to the first segment of audio data; and applying a synchronization mechanism between the first segment of audio data and the first segment of video data based on a predetermined indicator.

Abstract: A device, system, and method for adapting a current target rate of a video signal (VS) transmitted from a video provider (32) to a video receiver (10). The method includes receiving the video signal (VS) at the video receiver (10), measuring at the video receiver (10) at least an indicator of the received video signal (VS), the at least an indicator being different from a packet loss rate, calculating at the video receiver (10) a new target rate based on the current target rate of the received video signal (VS), the at least an indicator, and at least a reference, and transmitting from the video receiver (10) the new target rate to the video provider (32) to adapt the current target rate.

Abstract: A method for discriminating a telephony content signal into a first category or a second category is described. The method comprises a filtering procedure for obtaining from the telephony content signal a band signal set comprising one or more band signals, each band signal being associated with a respective frequency band at least one of said band signals being a sub-band signal (n) associated with a sub-band of an overall frequency band of the telephony content signal. Furthermore a determination procedure is provided for determining a band signal variation value (LLn) and a band signal strength value (TLn) for each band signal (n) of said band signal set. Finally, a discrimination procedure discriminates whether the telephony content signal is of the first category or of the second category.

Abstract: A method of dynamically adjusting the buffer delay of an adaptive jitter buffer of a network node receiving packets of a media stream from a packet switched network. The method comprises inserting packets arriving to the network node into the jitter buffer and executing a jitter buffering procedure once every Trepin, wherein Trepin is equal to the jitter buffer play-out interval. Executing the jitter buffer procedure involves updating a jitter protection time, Tjit, wherein Tjit defines a current target value for the maximum buffering delay, on the basis of the variation of the number of pending packets, N in the jitter buffer.

Abstract: The present invention relates to a method and a device for analyzing transport delay between a sender device and a receiver device in a communication system. In particular, the present invention relates to a method for estimating transport delay in a communication system comprising a sender device dividing a frame into segments, wherein each segment is transmitted in a packet with a send time stamp to a receiver device, the method comprising the steps of: receiving and time stamping packets with a receipt time stamp; identifying the relative-position of packets in a frame; calculating the offset of one or more packets in a frame, and performing transport delay analysis based on the send time stamp, the receipt time stamp, and the calculated offset of the one or more packets.
