摘要： A method for transmitting a computer display image. In one embodiment, the method comprises determining a pixel boundary, referenced to a sub-tile boundary within a grid of tiles, for a changed portion of the image; identifying i) a uniform tile within the changed portion referenced to a first tile and ii) at least one hybrid sub-tile, associated with the sub-tile boundary, within the changed portion referenced to a second tile adjacent the first tile; engaging an SIMD vector processor to transform the uniform tile to an exit matrix, transform the at least one hybrid sub-tile to at least one DC coefficient, and transform the exit matrix to a first DC coefficient and the at least one DC coefficient to a second DC coefficient; quantizing, encoding and transmitting coefficients of the first and second tiles; and transmitting a binary mask specification for the changed portion adjusted to the sub-tile boundary.

摘要： A method and apparatus for accessing a computer resource, wherein, during a first access sequence, the computer resource receives credentials of a user from a device the user is using to access the computer resource, encrypts the credentials using at least a first credentials key stores the encrypted credentials, communicates the first credentials key to a connection broker or to the device, and purges the first credentials key. The computer resource, during a subsequent access sequence, receives the first credentials key, decrypts the encrypted credentials using the first credentials key, and purges the first credentials key. The computer resource authenticates the user using the credentials and purges the credentials after the user is authenticated and enables the device to access the computer resource following the authentication of the user.

摘要： Methods of encoding an image stream. In one embodiment, the method comprises analyzing, for each block in a plurality of image blocks, changes from the same block in previous image frames; classifying each block as a non-video block if it has changed from a corresponding block in an immediately previous frame; re-classifying each non-video block as a video block if it meets video block requirements; encoding each non-video block having a first image type to a lossless quality level; encoding each non-video block having a second image type to a first lossy quality level; and encoding each video block to a second lossy quality level, wherein each of the lossless quality level, the first and the second lossy quality levels define a measurable image quality level of a decoded output of a corresponding block at a client computer, wherein the image frame comprises separate video insert, text and picture portions.
