Claim 7:
8. An apparatus comprising:
a transmitter;
a receiver;
memory;
instructions; and
processor circuitry to execute the instructions to:
access a first global unique identifier (GUID) obtained via an auxiliary channel during topology discovery, the first GUID corresponding to a first video or audio endpoint;
access a second GUID obtained via the auxiliary channel during the topology discovery, the second GUID corresponding to a second video or audio endpoint; and
determine that the first video or audio endpoint and the second video or audio endpoint are part of a same device when the first GUID corresponding to the first video or audio endpoint matches the second GUID corresponding to the second video or audio endpoint, the same device to store the first GUID in a first GUID register, the first GUID register corresponding to first DisplayPort configuration data (DPCD) registers, and the same device to store the second GUID from a container descriptor of the second video or audio endpoint.
