Abstract:
1. A method for initiating and optimizing the transmission of wireless video configuration data in a system comprising a display monitor connected to a first wireless adapter and a host computer connected by a wired connection to a second wireless adapter external to the host computer, the method comprising the steps of: (a) the second wireless adapter in response to initiation of a power up process pretending to be unplugged from the host computer; (b) the first wireless adapter in response to said initiation of said power up process detecting the display monitor and initiating a request from the first wireless adapter to the display monitor for EDID information as part of said startup process; (c) sending said EDID information from the display monitor to the first wireless adapter in response to said EDID request initiated by the first wireless adapter; (d) transmitting said EDID information over a wireless link from the first wireless adapter to the second wireless adapter; (e) the second wireless adapter ceasing to pretend to be unplugged from the host computer, initializing a connection controller of the second wireless adapter and activating a connection between the second wireless adapter and the host computer after said EDID information is received by the second wireless adapter, wherein data is not transmitted from the second wireless adapter over any wired interface until after the connection is activated; and (f) sending said EDID information from the second wireless adapter to the host computer after said initializing and said activating in response to an EDID request from the host computer, wherein the second wireless adapter acts as a proxy for the display monitor from the point of view of the host computer, (g) wherein the second wireless adapter initiates the overall process of routing said EDID information from the display monitor through said second and first wireless adapters to the host computer as part of said start up process.
