Abstract: A central unit for a digital conferencing system comprises a processing unit arranged for receiving a plurality of first control signals from a plurality of interpreter desks and indicating which interpreter channel is selected on an interpreter desk, and for identifying, based on the first control signals, which interpreter is interpreting in which interpreter channel and arranged for returning to and displaying on the plurality of interpreter desks a plurality of feedback signals. The central unit is arranged for receiving a plurality of second control signals from a plurality of listening units, and indicating which audio channel on a listening unit of the plurality of listening units is selected, for deriving, based on the plurality of second control signals, a total of listeners per listening channel and for sending to and displaying on the plurality of interpreter desks, information on the total of listeners per listening channel.

Abstract: An interpreter desk for a conferencing system is presented comprising a first interface configured to select an audio input channel from a plurality of audio input channels. Each corresponding to a different language, from which selected audio input channel a translation into a target language is to be performed. A processing unit is arranged to suggest one or more audio input channels and corresponding language as a source language for translation into the target language, based on at least one user preference and an indication of the quality of the different languages.

Abstract: The present disclosure provides a system for receiving signals over a power line distribution. Typically, problems of noise and interference are being solved at the receiver side. Systems of the present disclosure, however, are not limited to the receiver-side solution. Systems according to the present disclosure may also be used at the transmitter side. The receiver comprises a high pass filter, a preselect crossover filter, and an analog front-end receiver architecture.

Abstract: A circuit for end-of-burst detection in a portion of a received bit stream is disclosed. The circuit comprises: a first counter for counting the number of bits in the portion, a second counter for counting the number of bit value transitions in the portion, and a circuit for comparing the counted number of bits in the portion and the counted number of bit value transitions therein with preset values, the circuit for comparing is further arranged for generating a signal indicative of end-of-burst detection based on the result of the comparison.

Abstract: The present invention is related to a circuit (1) for detecting activity in a burst-mode receiver. The circuit is arranged for receiving an input signal (2) comprising a preamble. The circuit comprises a differentiator (11) for detecting signal transitions in the input signal (2) whereby the preamble comprises information on operating said differentiator (11). In a preferred embodiment, the information is a time constant. The circuit further comprises an integrator (12) arranged for being fed with an output of the differentiator. The resulting signal is compared to a reference (16). If this reference is crossed, activity is detected. In an embodiment a front-end circuit is presented comprising next to a circuit for detecting activity, a reset circuit arranged for resetting the front-end circuit and a clock phase alignment circuit arranged for recovering the phase.
