Image perfection for virtual presence architecture (VPA)
First Claim
Patent Images
1. A method of image improvement in a virtual presence architecture (VPA), the method comprising:
- a host computer in communication with a virtual presence server (VPS), a remote computer in communication with a virtual presence client (VPC), on each new screen resolution that is received by a VPS, adjusting a screen border to correspond with the new screen resolution;
identifying whether the adjusted screen border is near an expected location; and
if no border is found close to the expected border location, discarding the adjusted screen border and loading a predetermined set of values for the screen border instead.

Abstract
A method and system is disclosed for perfecting the images generated by a KVM switch. Video signals generated by a host computer are transmitted to a client computer in order to allow the user of a client computer to have a virtual presence on the host computer. However, the signals transmitted by the host computer may contain errors that would impair the client user'"'"'s ability to remotely control the host computer. Therefore this virtual presence architecture uses phase locked loops to compare screen data that is being sent to the client and removes errors so that the user data is properly transmitted and displayed.

6. A method of image improvement in a virtual presence architecture (VPA), the method comprising:
entering a phase locked loop (PLL) adjustment cycle each time a new screen resolution is detected;
trying a range of PLL values to detect a best value;
capturing two screens and comparing them;
if no acceptable match is found by the comparison, adjusting the tile color sensitivity and trying a complete set of values again; and
if no acceptable match is found again, reverting back to a set of factory settings. - View Dependent Claims (7, 8, 9, 10, 11, 12)
