Abstract
A system and method for synchronously transmitting media data is described. Synchronization data may be transmitted by a cycle master for receipt by one or more cycle slaves. A cycle slave may update an internal state based on the synchronization data received from the cycle master. The cycle master may transmit media data to multiple cycle slaves. The media data output by the cycle slaves may be determined, in part, by the internal state. In one embodiment, the media data may determine which cycle slave receives particular media data.
Claims18
A method of transmitting media data from a cycle master to multiple cycle slave devices and outputting the media data, the method comprising:
- synchronizing clocks within the cycle master and the multiple cycle slave devices;
- selecting one or more of the multiple cycle slave devices;
- transmitting the media data to each selected cycle slave device using a target address associated with a media data type of the media data;
- and
- outputting the media data from each selected cycle slave device based upon a state of a clock within each selected cycle slave device, wherein the outputting is controlled by an offset added to the clock within each selected cycle slave device.
A system for determining a destination for media data, the system comprising:
- a cycle master for transmitting the media data;
- multiple cycle slaves, each cycle slave including a clock synchronized to a cycle master clock;
- and
- a media inspector configured to determine which of the multiple cycle slaves receive the media data based on information associated with the media data,
- wherein outputting of the media data from one or more selected cycle slaves is controlled by an offset added to the clock within each selected cycle slave.
