1. An information handling system comprising:
- plural processing components operable to generate uncompressed visual information packets;
a source device operable to communicate the uncompressed visual information packets to a sink device, the source device further operable to retrieve identification information from the sink device; and
a packet stuffer associated with the source device, the packet stuffer operable to add a predetermined portion of the identification information to a predetermined position in each uncompressed visual information packet.

Abstract
DisplayPort micropackets of uncompressed visual information are adapted for communication across a network by stuffing packets with sink device identification information. For example, a packet stuffer adds selected portions of sink device EDID information to DisplayPort packets, such as EDID bytes 8 through 15, to a predetermined portion of the DisplayPort packets, such as between symbols FS and FE. Adding sink device identification information to each DisplayPort packet supports routing or switching of the packets to the identified sink device.
