Abstract: A video compression method may include providing and transmitting encoder commands for sequences of one or more pixels in a video frame in a YCbCr color space from a set of hierarchal encoder commands. A particular encoder command for a particular sequence may include on of a copy command, a delta command, or a make pixel command. A copy command may indicate that the particular sequence is identical to one of a previous pixel in the video frame, a pixel located above a first pixel of the particular sequence in the video frame, or a pixel in a previous video frame at a location of the first pixel. A delta command may indicate that the particular sequence includes a single pixel with color values equal to the previous pixel in the video frame combined with a signed color delta. A make pixel command may provide color values of particular sequence.

Abstract: Methods and systems are provided that allow a user to remotely access another computer and view its desktop without regard to whether that desktop has a relatively static image typical of a computer desktop, or whether it is playing a video, such as from a DVD. Relatively static screens may be displayed along with full motion video in such systems. These systems may also provide for both short mouse lag time when full motion video is displayed. In one implementation, hardware and firmware captures and encodes the video from the remote computer, and software on the client computer decodes the encoded video and displays it to the user.
