20160124463 | SYSTEM FOR CONTROLLING PERIPHERALS CONNECTED TO A DOCKING STATION - 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. | 05-05-2016 |
20150138217 | DISPLAY SYSTEM - A display system comprises a processing device connected to a plurality of display devices, the processing device comprising a processor connected to a system memory and to a graphics processing unit, the graphics processing unit comprising a graphics processor connected to a video memory. A method of operating the system comprises the steps of maintaining a system frame buffer in system memory, creating a shared primary surface in video memory for an additional display device not controlled by the graphics processing unit, rendering the contents of the system frame buffer onto the shared primary surface, rendering any and all directly rendered applications onto the shared primary surface, maintaining a second frame buffer in system memory, copying at least some of the content of the shared primary surface to the second frame buffer, and outputting at least some of the content of the second frame buffer to the additional display device. | 05-21-2015 |
20140267335 | Display Control Device - A display control device is connected to and controls a display device. The display control device comprises a frame buffer store, and a control component. The display control device is arranged to receive (S | 09-18-2014 |
20140267326 | PROCESSING OF DISPLAY DATA IN A DISPLAY SYSTEM - In a method of processing display data, a host device (e.g. a PC) determines display data to send to a remote device and compresses it, and determines processing resources required at the remote device to decompress the compressed display data. The host sends the compressed display data and control information regarding the required processing resources data to the remote device, and the remote device adjusts its processing resources based on the control information, saving energy. The required processing resources can be the number of processing units, clock speed, or operating voltage required by the remote device. The host may determine the required resources for each display frame. The remote device may send details of its processing capabilities to the host. | 09-18-2014 |
20140267321 | Image Generation - A method of generating an image comprises receiving a signal over a USB interface comprising encoded display data for one or more rectangular group of pixel tiles within an image and position data for the or each group of pixel tiles. The coefficients are obtained from the encoded display data, maybe by converting variable bit length fields into AC coefficients and an inverse Haar transform performed on them to generate pixel data for each rectangular group of pixel tiles. A frame buffer, which may be part of the display, is then updated with the generated pixel data ready for output to the display device. Copy protection may also be incorporated using AES negotiated over HDPC. | 09-18-2014 |
