Abstract
Resources may be managed in a topology for audio/video streaming. The topology includes audio/video sources and sinks and intervening branch devices. Messages between these sources, sinks, and branch devices may be used for resource management.
Claims22
1-24. (canceled)
A storage device comprising instructions that, when executed, cause a processor to at least:
- obtain a first global unique identifier (GUID) via an auxiliary channel from a topology of devices, the first GUID corresponding to a first function;
- obtain a second GUID via the auxiliary channel from the topology of devices, the second GUID corresponding to a second function;
- and
- determine that the first function and the second function are part of a same one of the devices when the first GUID corresponding to the first function matches the second GUID corresponding to the second function, the same one of the devices to include the first GUID in a first GUID register, the first GUID register being one of first DisplayPort configuration data (DPCD) registers, and the same one of the devices to include the second GUID in a container descriptor of the second function.
1 more element
An apparatus comprising:
- a transmitter;
- a receiver;
- memory;
- and
- at least one processor to execute instructions to:
- obtain a first global unique identifier (GUID) via an auxiliary channel from a topology of devices, the first GUID corresponding to a first function;
- obtain a second GUID via the auxiliary channel from the topology of devices, the second GUID corresponding to a second function;
- and
- determine that the first function and the second function are part of a same one of the devices when the first GUID corresponding to the first function matches the second GUID corresponding to the second function, the same one of the devices to include the first GUID in a first GUID register, the first GUID register corresponding to first DisplayPort configuration data (DPCD) registers, and the same one of the devices to include the second GUID from a container descriptor of the second function.
6 more elements
An apparatus comprising:
- means for receiving a first global unique identifier (GUID) and a second GUID from a topology of devices via an auxiliary channel, the first GUID corresponding to a first function, and the second GUID corresponding to a second function;
- and
- means for processing the first and second GUIDs to determine that the first function and the second function are part of a same one of the devices based on a match between the first GUID and the second GUID, the same one of the devices to include the first GUID in a first GUID register, the first GUID register being one of a plurality of DisplayPort configuration data (DPCD) registers, and the same one of the devices to include the second GUID in a container descriptor of the second function.
