Abstract

An accessory is provided wireless connectivity with a game console by reconfiguring an earlier transport format that was used to solely transport voice data packets. The reconfiguration incorporates the use of a hybrid sub-frame, wherein voice data packets are replaced with communication data packets. The replacement is indicated by a set of identification bits inserted into a payload identifier field of the hybrid sub-frame.

Claims

1. A method of communicating information between a wireless headset unit and a game console, the method comprising:

assigning in an upstream frame of data packets directed from the wireless headset unit to the game console, an upstream hybrid sub-frame for transporting upstream voice data packets and communication data packets; and

replacing upstream voice data packets with communication data packets, the replacement being identified by insertion of a first set of identification bits into a payload identifier field of the upstream hybrid sub-frame, wherein;

the upstream communication data packets are carried in

a payload field of the upstream hybrid sub-frame; and

an absence of the first set of identification bits in the payload identifier field of the upstream hybrid sub-frame indicates that the data packets carried in the payload field of the upstream hybrid sub-frame are upstream voice data packets.

2. The method of claim 1, further comprising:

assigning in a downstream frame of data packets directed from the game console to the wireless headset unit, a downstream hybrid sub-frame for transportation of downstream voice data packets and communication data packets; and

replacing downstream voice data packets with communication data packets, the replacement being identified by insertion of a first set of identification bits into a payload identifier field of the downstream hybrid sub-frame.

3. The method of claim 2, wherein an absence of the second set of identification bits in the payload identifier field of the downstream hybrid sub-frame indicates that the data packets carried in the payload field of the downstream hybrid sub-frame are downstream voice data packets.

4. The method of claim 3, wherein the first set of identification bits is identical to the second set of identification bits.

5. The method of claim 4, wherein each of the first and second sets of identification bits contains two data bits.

6. The method of claim 2, further comprising:

inserting in a packet-type identifier field of the upstream hybrid sub-frame, a first set of classification bits that defines the type of information carried in the upstream communication data packets.

7. The method of claim 6, further comprising:

inserting in a packet-type identifier field of the downstream hybrid sub-frame, a second set of classification bits that defines the type of information carried in the downstream communication data packets.

8. The method of claim 7, wherein the payload field of the upstream hybrid sub-frame contains a greater number of bits than the payload field of the downstream hybrid sub-frame.

9. A communication system comprising:

a wireless headset unit comprising an upstream hybrid sub-frame for transportation of upstream voice data packets and communication data packets, the upstream sub-frame comprising an upstream payload identifier field configured to transport a first set of identification bits indicative of a replacement of upstream voice data packets with upstream communication data packets; and

a game console configured to receive the upstream hybrid sub-frame of data packets transmitted by the wireless headset unit, the game console further configured to transmit a downstream frame of data packets to the wireless headset unit, the downstream frame of data packets containing a downstream hybrid sub-frame for transportation of downstream voice data packets and communication data packets, the downstream hybrid sub-frame comprising a downstream payload identifier field configured to transport a second set of identification bits indicative of a replacement of downstream voice data packets with downstream communication data packets, wherein;

the upstream communication data packets are carried in a payload field of the upstream hybrid sub-frame; and

an absence of the first set of identification bits in the payload identifier field of the upstream hybrid sub-frame indicates that the data packets carried in the payload field of the upstream hybrid sub-frame are upstream voice data packets.

10. The communication system of claim 9, wherein the downstream hybrid sub-frame comprises a downstream payload field configured to carry the downstream voice data packets.

11. The communication system of claim 10, wherein the wireless headset unit is configured to extract the upstream communication data packets from the upstream payload field upon detection of the first set of identification bits in the upstream payload identifier field;

and to extract the upstream voice data packets from the upstream payload field when the first set of identification bits is not present in the upstream payload identifier field.

12. The communication system of claim 11, wherein the game console is configured to extract the downstream communication data packets from the downstream payload field upon detection of the second set of identification bits in the downstream payload identifier field;

and to extract the downstream voice data packets from the downstream payload field when the second set of identification bits is not present in the downstream payload identifier field.

13. The communication system of claim 9, wherein the upstream and downstream frames of data packets are transported in a Time Division Multiple Access (TDMA) wireless format.

14. A computer-readable storage medium having stored thereon computer-executable instructions for providing communications between a wireless headset unit and a game console by performing the steps of:

configuring an upstream hybrid sub-frame for transportation of upstream voice data packets from the wireless headset unit to the game console; and

inserting in a payload identifier field of the upstream hybrid sub-frame, a first set of identification bits indicative of a replacement of upstream voice data packets with upstream communication data packets, wherein;

the upstream communication data packets are carried in a payload field of the upstream hybrid sub-frame; and

an absence of the first set of identification bits in the payload identifier field of the upstream hybrid sub-frame indicates that the data packets carried in the payload field of the upstream hybrid sub-frame are upstream voice data packets.

15. The computer-readable medium of claim 14, additionally comprising computer-executable instruction for performing the steps of:

configuring a downstream hybrid sub-frame for transportation of downstream voice data packets from the game console to the wireless headset unit; and

inserting in a payload identifier field of the downstream hybrid sub-frame, a second set of identification bits indicative of a replacement of downstream voice data packets with downstream communication data packets.

16. The computer-readable medium of claim 15, additionally comprising computer-executable instruction for performing the steps of:

17. The computer-readable medium of claim 16, additionally comprising computer-executable instruction for performing the steps of:

extracting the downstream communication data packets from the downstream payload field upon detection of the second set of identification bits in the downstream payload identifier field; and

18. The computer-readable medium of claim 17, additionally comprising computer-executable instruction for performing the steps of:

inserting in a packet-type identifier field of the upstream hybrid sub-frame, a first set of classification bits that defines the type of information carried in the upstream communication data packets.
