Abstract

A method of communicating among participants at participant stations 1-N, the participant stations 1-N connected to a data communications network. A number of audio packet queues 1-N are assigned to each participant station 1-N. A composite audio packet is sent over the data communications network to each of the stations. The composite audio packet is comprised of an audio packet and a sending station identification (ID), the sending station ID corresponding to the station at which the composite packet originates. When the talking is done, a composite end-of-utterance marker packet is sent over the data communications network to each station. The composite end-of-utterance marker packet is comprised of an end-of-utterance marker and the sending station ID. At a receiving station, the audio packet corresponding to the sending station at which the composite packet originates is placed in an audio packet queue allocated to that sending station. The receiving station detects the composite end-of-utterance marker packet, at which time the contents of the audio packet queue are moved to a ready-to-play queue. The audio packets are played back from the ready-to-play queue.

Claims

1. Apparatus comprising:

an interface that operates to couple the apparatus to one or more other apparatuses to facilitate a user of the apparatus to engage in a multi-party audio chat with user(s) of one or more other apparatuses;

audio mechanism coupled to the interface to facilitate said user of the apparatus to utter to the other user(s) of the multi-party chat, in a manner that allows the user'"'"'s utterances to be staged by the other apparatus(es), separate from other utterances received by the other apparatuses, prior to rendering the user'"'"'s utterances; and

control mechanism coupled to the interface to facilitate said user of the apparatus to denote an end-of-utterance condition to the other apparatus(es) to allow the other apparatus(es) to render received utterances in order.

2. The apparatus as set forth in claim 1, wherein the user of the apparatus engages the control mechanism whenever the user utters, and disengages whenever the user stops uttering, the control mechanism denoting the end-of-utterance condition to the other apparatus(es) when the user disengages the control mechanism.

3. The apparatus as set forth in claim 2, wherein the control mechanism includes a graphical user interface icon designed to be selected by the user of the apparatus whenever the user utters, and deselected whenever the user stops uttering, the control mechanism denoting the end-of-utterance condition to the other apparatus(es) when the user deselects the icon.

4. The apparatus as set forth in claim 2, wherein the control mechanism includes a mechanical switch designed to be set by the user of the apparatus, whenever the user utters, and unset by the user whenever the user stops uttering, the control mechanism denoting the end-of-utterance condition to the other apparatus(es) when the user unsets the mechanical switch.

5. An apparatus comprising:

an interface that operates to couple the apparatus to one or more other apparatuses to facilitate a user of the apparatus to engage in a multi-party audio chat with user(s) of one or more other apparatuses;

staging mechanism coupled to the interface to facilitate separate staging of received utterances from the other user(s) of the multi-party chat; and

audio mechanism coupled to the staging mechanism that renders in order completed ones the separately staged utterances.

6. The apparatus as set forth in claim 5, wherein the staging mechanism includes a first plurality of queues operate to queue audio packets received from the one or more other apparatuses, one queue for each user of the one or more apparatuses.

7. The apparatus as set forth in claim 6, wherein the staging mechanism associates and queues a received audio packet with a corresponding one of the first plurality of queues in accordance with a speaker identification included the received audio packet.

8. The apparatus as set forth in claim 6, wherein the staging mechanism further includes a second queue operates to accept and queue audio packets of completed utterances from the first plurality of queues.

9. The apparatus as set forth in claim 5, wherein when there is more than one other user associated with the multi-party chat, the audio mechanism operates to render the separately staged utterances of the other users in accordance with when the other users complete their respective utterances.

10. The apparatus as set forth in claim 5, wherein when there is more than one other user associated with the multi-party chat, the audio mechanism operates to render the separately staged utterances of the other users without mixing their respective utterances.

11. A method comprising:

(a) transmitting utterances of a participant of a multi-party chat to one or more other participants of the multi-party chat, the utterances being transmitted in a manner that allows the utterances to be staged by the other participant(s), separate from other utterances received by the other participant(s), prior to rendering the participant'"'"'s utterances;

(b) transmitting an end-of-utterance indication to the other participant(s), when the participant stops uttering, to allow utterances received by the other participant(s) to be rendered in order.

12. The method of claim 11, wherein the method further comprises:

(c) communicating to an apparatus on which the method is being practice, the fact that the participant is uttering.

13. The method of claim 12, wherein (c) comprises selecting a graphical user interface icon whenever the participant utters, and deselecting the icon whenever the participant stop uttering.

14. The method of claim 12, wherein (c) comprises selecting setting a mechanical switch whenever the participant utters, and unsetting the mechanical switch whenever the participant stop uttering.

15. The method of claim 11, wherein (a) comprises transmitting the participant'"'"'s utterances as audio packets, including identification information identifying the participant.

16. The method of claim 11, wherein (b) comprises transmitting an end-ofutterance packet.

17. A method comprising:

(a) receiving utterance audio packets from other participants of a multi-party chat, and separately queuing the received utterance audio packets in a plurality of queues, one queue per other participant; and

(b) rendering the queued utterance audio packets in order.

18. The method of claim 17, wherein (a) further comprises receiving end-of-utterance packets from the other participants completing utterances, and moving the queued utterance audio packets of the other participants completed utterances onto a rendering queue.

19. The method of claim 17, wherein (b) comprises rendering the queued utterance audio packets in order of the other participants'"'"' respective completion of their utterances.

20. The method of claim 17, wherein (b) comprises rendering the queued utterance audio packets of the other participants without mixing queued utterance audio packets of different other participants.
