Embodiment Construction

[0277] The following examples refer to Figure 7 The flowchart describes the mechanism for publishing TX delay times and agreeing receiver delay time offsets. In this example, the following assumptions are made:

[0278] - Synchronize network time of multiple participating devices.

[0279] - Transmitters timestamp their output frames / samples according to a shared notion of time.

[0280] - The receiver is able to time synchronize the output with the shared time and the timestamp of the frame or sample.

[0281] Each transmission channel has a local transmitter delay time 50 and an external delay time 60 associated therewith. These values ​​are available to the receiver 18 through entries in a shared database (eg DNS-SD). The receiver 18 should not select a delay time value less than the value 50. To determine the set time-stamped delay time 44, in step 92, the receiver delay time 50 is calculated with any other delay time available to the receiver. The sum of the values ...
