A method of encoding display output of a computer using a block-based video encoder, such as H.264 includes receiving display update information, the display update information specifying at least one changed display area. Pixel data associated with the at least one changed area is also received. For each image block of an output frame to be encoded, the encoder determines whether the image block intersects one or more of the changed areas. A block skip indication is encoded for each image block not intersecting at least one changed area, and pixel data is encoded for intersecting blocks. An encoded output frame is then generated including the block skip indications and encoded pixel data.

Efficient encoding of display data

A method for determining which of a plurality of mobile devices connected to the docking station is permitted to control the peripherals involves the docking station determining whether a new mobile device is connected to an input port of the docking station, and, if so, whether the new mobile device is capable of controlling any of the peripherals connected to the docking station. If it is determined that the new mobile device is not capable of controlling any of the peripherals, the docking station determines that the new mobile device is to be connected as a peripheral. If it is determined that the new mobile device is capable of controlling one or more of the peripherals, the docking station determines whether an existing mobile device connected to the docking station has control of the peripherals as a host device, and, if so, determining which of the new mobile device or the existing mobile device has a higher priority to control the peripherals as the host device, and providing the determined host device access to control the peripherals.
