If, after having delivered an utterance, a plurality of undelivered utterances remains to be delivered, the one utterance that was finished first is delivered first. This promotes the participants to make their utterances not too long, because utterances of other participants that are ended earlier will be delivered first.
  • the arbitrator is arranged for refraining from causing the utterance to be delivered if it has not been delivered within a predetermined time after it was received. This helps to avoid the storage means to become full. Also, in some applications the value or the relevance of an utterance may become small after a certain period of time, and it may be better not to deliver utterances that have not been delivered within this period of time.
  • the input comprises means for establishing a begin and an end of the received utterance by monitoring at least one button to be pressed by the participant and/or by a signal level monitoring of an audio input.

Any time before or after the utterance may be discarded, even if the button is depressed.

Abstract

L'invention porte sur un système (110) pour fournir un service de communications, lequel système comporte une entrée (114) pour recevoir un énoncé (T1) d'un premier participant (101) du service de communications. Des moyens de stockage (118) sont prévus pour stocker l'énoncé au moins temporairement jusqu'à ce qu'il soit délivré à un second participant (103) du dispositif de communications. Un arbitre (112) détermine quand distribuer l'énoncé au second participant, en fonction d'éventuels énoncés non délivrés (T2) reçus au niveau de l'entrée depuis d'autres participants (102), assurant qu'un seul énoncé est délivré à la fois. Une sortie (116) est utilisée pour délivrer l'énoncé au second participant à l'instant déterminé par l'arbitre.
