Wireless keyboard, video, mouse device
A wireless keyboard, video, mouse (KVM) system includes transmitting compressed video signals. Analog video data is converted from RGB signals to YUV signals which are compressed using a linear interpolation algorithm.
1 . In a wireless keyboard, video, mouse (KVM) system, a method of transmitting video signals, comprising:
converting analog video data from RGB signals to YUV signals;
compressing the YUV signals; and
providing the compressed YUV signals.
2 . A method as in claim 1 wherein Y signals of the YUV signals and UV signals of the YUV signals are processed in two groups.
3 . A method as in claim 1 wherein the compressing comprises:
compressing the Y and UV data using a linear interpolation algorithm, and wherein the compressed YUV signals represent line segments.
4 . A method as in claim 3 further comprising:
providing at least some of the endpoints using relative coordinates.
5 . A method as in claim 1 wherein the RGB video signals are represented by 24 bits, the YUV signals are represented by 24 bits and at least some compressed YUV signals are represented by 16-bit line segments.
6 . In a wireless keyboard, video, mouse (KVM) system, a method of processing video signals, comprising:
obtaining a compressed YUV signal;
decompressing the compressed YUV signal to obtain a YUV signal; and
converting the YUV signal to an RGB signal.
7 . A method as in claim 6 wherein the compressed YUV signals represent line segments.
8 . A method as in claim 7 wherein the RGB video signals are represented by 24 bits, the YUV signals are represented by 24 bits and at least some compressed YUV signals are represented by 16-bit line segments.
