Abstract

A system and a method for dynamically synchronizing a client (110) to a data source (105). The method can include the step of dynamically selecting a first length of format data to correspond to an amount of bandwidth of a commutated bitstream (115) allocated for synchronization. At least a first portion of a first format definition can be transmitted in the commutated bitstream (115). A size of the first portion can correspond to the first length of format data. The method also can include transmitting a current sentinel (205) in the commutated bitstream (115), the current sentinel (205) identifying a current commutation format of the commutated bitstream (115). An indication (120) can be received from the client that indicates that the client requires the first format definition. The step of transmitting the first portion of the first format definition can be responsive to the client indication.

Claims

1. A method for dynamically synchronizing a client to a data source comprising:

dynamically selecting a first length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization; and

transmitting in the commutated bitstream at least a first portion of a first format definition, a size of the first portion of the first format definition corresponding to the first length of format data.

2. The method according to claim 1, further comprising transmitting a current sentinel in the commutated bitstream, the current sentinel identifying a current commutation format of the commutated bitstream.

3. The method according to claim 1, further comprising receiving from a client an indication that the client requires the first format definition.

4. The method according to claim 3, wherein said step of transmitting the first portion of the first format definition is responsive to said step of receiving the indication from the client.

5. The method according to claim 1, further comprising:

dynamically selecting a second length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization; and

transmitting in the commutated bitstream at least a second portion of the first format definition, a size of the second portion of the first format definition corresponding to the second length of format data.

6. The method according to claim 1, further comprising transmitting a cyclic sentinel in the commutated bitstream, the cyclic sentinel identifying at least a second commutation format forthcoming for the commutated bitstream.

7. The method according to claim 6, further comprising:

receiving from a client an indication that the client requires a second format definition correlating to the second commutation format.

8. The method according to claim 7, further comprising:

responsive to said step of receiving from the client the indication, transmitting in the commutated bitstream at least a portion of the second format definition.

9. The method according to claim 8, wherein a size of the portion of the second format definition corresponds to the first length of format data.

10. The method according to claim 9, further comprising:

dynamically selecting a second length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization, wherein the size of the portion of the second format definition corresponds to the second length of format data.

11. A dynamically synchronized communication system comprising:

a data source that dynamically selects a first length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization, the data source transmitting in the commutated bitstream at least a first portion of a first format definition, a size of the first portion of the first format definition corresponding to the first length of format data.

12. The system of claim 11, wherein the data source transmits a current sentinel in the commutated bitstream, the current sentinel identifying a current commutation format of the commutated bitstream.

13. The system of claim 11, wherein the data source receives from a client an indication that the client requires the first format definition.

14. The system of claim 13, wherein said data source transmits the first portion of the first format definition in response to receiving the indication from the client.

15. The system of claim 11, wherein the data source dynamically selects a second length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization, and the data source transmits in the commutated bitstream at least a second portion of the first format definition, a size of the second portion of the first format definition corresponding to the second length of format data.

16. The system of claim 11, wherein the data source further transmits a cyclic sentinel in the commutated bitstream, the cyclic sentinel identifying at least a second commutation format forthcoming for the commutated bitstream.

17. The system of claim 16, wherein the data source receives from a client an indication that the client requires a second format definition correlating to the second commutation format.

18. The system of claim 17, wherein the data source transmits in the commutated bitstream at least a portion of the second format definition responsive to the client the indication.

19. The system of claim 18, wherein a size of the portion of the second format definition corresponds to the first length of format data.

20. The system of claim 19, wherein the data source dynamically selects a second length of format data to correspond to an amount of bandwidth of a commutated bitstream allocated for synchronization, wherein the size of the portion of the second format definition corresponds to the second length of format data.
