Abstract: Systems and methods for providing a visible watermark in a remote session. The methods comprise: determining if a graphic update needs to be made at a client computing device during the remote session; generating a first graphic update message in response to a determination that a graphic update is needed; identifying pixels of the graphic which would be affected by at least one watermark if the graphic and watermark were both displayed on a screen of the client computing device; constructing a second string of commands specifying a new color value for each of the pixels that were previously identified; converting the first graphic update message to a second graphic update message by inserting the second string of commands in between a first string of commands and an End-Of-Frame (“EOF”) command; and communicating the second graphic update message from the sever to the client computing device.

Abstract: An encoder includes a processor and a memory coupled thereto. A digital image to be encoded is stored in the memory. The digital image includes an array of pixels, with each pixel having an RGB color value associated therewith. Image filtering is performed on the digital image and includes calculating an RGB Euclidean geometric distance between a current pixel and a prior pixel, comparing the calculated RGB Euclidean geometric distance to a threshold, and changing the RGB color value of the current pixel to the same RGB color value as the prior pixel when the calculated RGB Euclidean geometric distance is less than the threshold. Run length encoding is performed on the filtered digital image.

Abstract: Systems and methods are provided for encoding a multi-pixel caching scheme for lossless encoders. The systems and methods can include obtaining a sequence of pixels, determining repeating sub-sequences of the sequence of pixels consisting of a single repeated pixel and non-repeating sub-sequences of the sequence of pixels, responsive to the determination, encoding the repeating sub-sequences using a run-length of the repeated pixel and encoding the non-repeating sub-sequences using a multi-pixel cache, wherein the encoding using a multi-pixel cache comprises, encoding non-repeating sub-sequences stored in the multi-pixel cache as the location of the non-repeating sub-sequences in the multi-pixel cache, and encoding non-repeating sub-sequences not stored in the multi-pixel cache using the value of the pixels in the non-repeating sub-sequences.

Abstract: Computer-implemented systems and methods are disclosed for encoding a display frame, wherein the systems and methods acquire a plurality of display frames. The computer implemented systems and methods further detect transient regions for a display frame of the plurality of display frames. Systems and methods are disclosed for encoding transient regions of a display frame using a first encoding mechanism if the display frame contains transient regions. Further, systems and methods are disclosed for encoding non-transient regions using a second encoding mechanism if the display frame contains non-transient regions.
