  • Patent number: 8942243
    Abstract: The invention relates to a method for controlling a bit-rate of a session in a packet-switched communications system where multiple sessions are set-up via a shared resource. A current bit-rate of the session is compared to a bit-rate range valid for the session to determine a distance from the position of the current bit-rate to one of the end-points of the bit-rate range. The current bit-rate is then adapted differently depending on the distance to the selected end-point. By controlling the bit-rate of each session that is set-up via the shared resource for applications that provide delay-sensitive services to users in this way the method and corresponding system and sender-receiver arrangements have the effect that rate adaptations can be distributed among the applications so that users share responsibility for rate adaptations.

  • Patent number: 8625608
    Abstract: The invention relates to a method for controlling a bit-rate of a session in a packet-switched communications system where multiple sessions are set-up via a shared resource. A current bit-rate of the session is compared to a bit-rate range valid for the session to determine a distance from the position of the current bit-rate to one of the end-points of the bit-rate range. The current bit-rate is then adapted differently depending on the distance to the selected end-point. By controlling the bit-rate of each session that is set-up via the shared resource for applications that provide delay-sensitive services to users in this way the method and corresponding system and sender-receiver arrangements have the effect that rate adaptations can be distributed among the applications so that users share responsibility for rate adaptations.

  • Patent number: 8571039
    Abstract: A method and apparatus for transmitting an audio signal over a communication channel comprising encoding the audio signal with an encoder 204 using a first sampling rate, filtering the audio signal using a first cut off frequency, the first cut off frequency being chosen in dependence upon the first sampling rate, and transmitting the encoded and filtered audio signal over the communication channel. The presence of a condition in which the sampling rate of the encoder 204 is to be switched to a second sampling rate at a switching time is determined and if the condition has been determined to be present, the cut off frequency used in the filtering step is gradually changed from the first cut off frequency to a second cut off frequency, the second cut off frequency being chosen in dependence upon the second sampling rate, such that the audio bandwidth of the transmitted signal changes gradually when the sampling rate is switched to the second sampling rate.

  • Patent number: 8560723
    Abstract: The present invention concerns a method of calculating a filtered filling level of the input buffer of a gateway generating a data stream from a received data stream resisting the jitter of the stream received. It applies more particularly to a gateway receiving an MPEG (Moving Picture Experts Group) transport stream received according to the IP protocol (Internet Protocol) and retransmitted over an ASI interface (Asynchronous Serial Interface). The invention proposes a method of calculating a filtered filling level of the input buffer resisting the jitter of the stream received. The received stream passing through an input buffer, the method is based on a regulation as a function of the maximum level of the buffer evaluated over a period of time, making it possible to protect against the effects of the jitter introduced into the received stream.

  • Patent number: 8477789
    Abstract: A transmission device (100) outputs, to a reception device (200), a stored amount of packets in a first transmission buffer (105) just before a certain packet has been written to the first transmission buffer. A first reception buffer amount read unit (206) in the reception device reads a stored amount of packets in a first reception buffer just before the certain packet has been read from the first reception buffer. A storage amount addition unit (207) adds the stored amount of packets in the first transmission buffer and the stored amount of packets in the first reception buffer, and a correction unit (208) adjusts the frequency of a variable frequency oscillator in a reception timestamp timer 209 so that the resulting added value is a constant value.
