System for video digitization and image correction for use with a computer management system
First Claim
1. A Keyboard, Video, Mouse (“
- KVM”
) system with improved video digitization and image correction, said KVM system comprising;
a remote management unit;
a plurality of workstations each containing at least a keyboard or cursor control device, wherein the plurality of workstations are coupled to the remote management unit via a first communications medium,a plurality of remote networking devices coupled to the remote management unit via a second communications medium;
wherein the remote management unit includes;
a Liquid Crystal Display (“
LCD”
) controller comprising an analog-to-digital (“
A/D”
) converter, the LCD controller for converting analog video signals received from at least one of the remote networking devices to image-correction processed digital video signals,a video processor circuit for compressing said image-correction processed digital video signals,a packetizer for packetizing the compressed, image-correction processed digital video signals, andmodules for processing and bidirectionally communicating over the first communications medium keyboard and cursor control signals to and from the plurality of workstations and for transmitting the packetized, compressed, image-correction processed digital signals to the plurality of workstations via the first communication medium, andwherein all keyboard and cursor control device signals bidirectionally pass through the LCD controller unprocessed.

Abstract
The present invention discloses a remote network management system for coupling a series of remote serial devices, servers, and computers to one or more user workstations allowing for selective access of the remote devices. The remote serial devices, servers, and computers are all connected to a remote management unit which interfaces the user workstations to the remote devices. The power supply of each remote device is also connected to the remote management unit through a controllable power supply. The video from the remote networking equipment is digitized and optimized by an LCD controller located within the remote management unit before it is compressed for transmission. An option menu containing a menu of all the remote devices allows a user to select and operate any of the remote devices. The option menu is also utilizes to selectively control the power to the remote serial devices, servers, and computers.

22. A method for providing improved video digitization and image correction in a KVM system, said method comprising the steps of:
-
receiving analog video signals and control signals from one of a plurality of remote devices connected to a remote management unit; processing the received analog video signals using an analog-to-digital (“
A/D”
) converter element of an LCD controller to convert the analog video signals to digital video signals;correcting the digital video signals by the LCD controller to form image-correction processed digital video signals; passing the control signals to and from one of the plurality of remote devices through the LCD controller unprocessed and uncorrected; compressing the image-correction processed digital video signals by a video processor circuit; packetizing the compressed, image-correction processed digital video signals by a packetizer, and transmitting the packetized, compressed image-correction processed digital video signals and the control signals to one of a plurality of user interface devices. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
