摘要： A number of computing devices (13) are controlled from a touchscreen display system (11) using a Touch Intermediator Machine (TIM) (12) receiving information indicating the location of one or more touches on a connected touchscreen panel (11). The TIM (12) determines whether the pattern of touches received matches one of a pre-programmed set of interface manipulation gestures. If so, the TIM (12) alters the user interface presented on the connected touchscreen display system (11) depending on the gesture detected. If not, the TIM (12) determines the connected computing device (13) associated with the location of the touch received and updated co-ordinates of the touch received within an area on the touchscreen display system (11) associated with the connected computing device (13). The TIM (12) transmits information to the relevant connected computing device (13) regarding the touch received. The computing device (13) processes the information to determine the pattern of touches received and responds to the pattern of touches received according to predetermined instructions for user interaction.

摘要： A method of generating display data by a host device for transmission over a variable bandwidth connection to a display control device for display involves receiving (S42), at the host device, information indicative of available bandwidth on the variable bandwidth connection between the host device and the display control device, which may be based on monitoring a signal level on the connection, a link radio modulation mode, traffic on the connection, or the data rate of any return signals from the display control device. The host device then sets (S44) one or more parameters used to generate the display data that change compressibility of the display data based on the information, where compressibility of the display data affects efficiency of compression of the display data. The parameters may be chosen from parameters controlling colour depth, colour space, spatial frequency, quantisation level, supersampling, and frame rate. The setting of the one or more parameters may be based on a compression algorithm used when compressing the display data. The display data is then generated using the one or more parameters, compressed, and transmitted to the display control device.

摘要： In virtual-reality display devices it is possible to use head movement as an input to compression, which assumes that the user is looking at something that is moving at approximately the same rate in the same direction as the user's head. This method determines whether an eye of a user of a head mounted display is directed at a relatively fixed point. The method involves detecting (S51) a movement of the user's head, including a lack of movement thereof, determining (S53) a direction of the movement of the user's head, detecting (S52) movement of at least one eye of the user, including a lack of movement thereof, and determining (S54) a direction of the movement of the user's eye. If the directions of movement of the user's head and at the user's eye are different (S55), within a predetermined threshold, it can be assumed that the user's eye is directed at a fixed point (S57), whereas if the directions of movement of the user's head and the user's eye are not different (S55), within a predetermined threshold, then it can be assumed that the user's eye is not directed at a fixed point (S56).

摘要： A method of compressing image data involves determining an active area of an image to be displayed, at least part of which changes from frame to frame to provide a moving image. Color values for each pixel in at least part of the active area that has changed are determined (S73) and a resolution of a blue component of the color values is dynamically reduced (S75) relative to resolutions of green and red components of the color values. The image data is then transmitted, together with error correction information indicating how to correct the blue component when the image data is displayed. The active area may be a particularly fast changing part of the image or an area on which a user is focused.

摘要： 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.

摘要： A heterogeneous multi-core integrated circuit comprising two or more processors, at least one of the processors being a general purpose CPU and at least one of the processors being a specialized hardware processing engine, the processors being connected by a processor local bus on the integrated circuit, wherein the general purpose CPU is configured to generate a first instruction for an atomic operation to be performed by a second processor, different from the general purpose CPU, the first instruction comprising an address of the second processor and a first command indicating a first action to be executed by the second processor, and transmit the first instruction to the second processor over the processor local bus. The first command may include the first action, or may be a descriptor of the first action or a pointer to where the first action may be found in a memory.

摘要： Data, particularly display data, is sent to a particular peripheral device, particularly a display device) from a computer device, such as a mobile device. The method involves determining an identifier of each peripheral device and receiving (35) a user identification identifying a particular peripheral device. The user identification is then associated (36) with the identifier of the particular peripheral device, and data is sent to the particular peripheral device based on the identifier associated with the user identification. The user identification comprises a user gesture which is captured as an input image, which is processed to determine which particular peripheral device the user gesture is gesturing towards and associating the user gesture with the identifier of the particular peripheral device. Alternatively the user identification may be directly input by a user on a display showing either recognised elements that have been associated with identifiers of the peripheral devices, or a listing of available peripheral devices.

摘要： 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.

摘要： 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.
