摘要： A wireless content protection system includes a coordinator, a source device, and a sink device. The coordinator includes a scheduler. The source and sink devices each have a content protection manager. One of the content protection manager allocates and releases bandwidth via the coordinator for a test message and a response message for a round-trip time computation. The test message is transmitted in a source-to-sink channel time block. The response message is transmitted in a sink-to-source channel time block. The round-trip time is the period between the end of the source-to-sink channel time block and the beginning of the sink-to-source channel time block.

摘要： A network device may include a timing module and at least one interface. The timing module determines a local time of the network device indicating when the network device sends a synchronization start message. The at least one interface sends the synchronization start message to a time client device to set the current time of day on the time client device, receives a synchronization response message from the time client device indicating that the current time of day of the time client device was set, and sends a synchronization success message to the time client device indicating that the time client device has correctly set its current time of day.
