Abstract: A video redirection system redirects an incoming video stream to a remote console. The video redirection system samples the video stream to generate a currently sampled frame comprising a plurality of tiles, and calculates a current hash value for each of the tiles. The video redirection system compresses the tile if the current hash value is different from a reference hash value locally stored inside the video redirection system. A difference in the hash value indicates that there is a change in the tile of the currently sampled frame from the corresponding tile of the previously sampled frame. Thus, it is no longer necessary to compare the currently sampled frame with a reference frame in the memory. Accordingly, the amount of memory access is reduced.

Abstract: A method, device and system for using a first verification algorithm or program to evaluate the integrity or authenticity of a second verification program. The first verification program may be stored in a device and may compare a result of such evaluation with a stored expected result. The second verification program may be included in for example an attachable memory unit of the device or other for example add-on memory unit of the device. The second verification program may evaluate the authenticity or integrity of firmware, software, data or other code that is included on the attachable device or elsewhere in the device. If both verification programs confirm the integrity of the respective codes, the firmware or software may be executed or loaded for execution by the device.
