摘要： A method of displaying a portion of an image (13) on a mobile device (15b) having a screen by communicatively coupling the mobile device (15b) to a computer device (11) displaying an image (13) on a display (12) under the control of the computer device (11), receiving image data relating to the image (13) from the computer device (11), and displaying an area (16b) of the image (13) on the screen of the mobile device (15b), the area (16b) having a magnification factor compared to the image (13). The magnification factor may be selected by the user according to the level of detail that is required and therefore allows the user to view the magnified area (16b) more privately, which may be appropriate in a presentation context where a member of the audience has difficulty seeing the screen and wishes to instead view the presentation or magnified sections of it on a hand-held device.

摘要： A USB dock (32) which includes a USB data hub (35) that does not provide negotiated power levels to devices connected to the USB dock (32), is connected to a host device (31) via a USB connection and to a peripheral device (33) via a USB connection and a power connection. The USB dock (32) includes a power source (37) connected to the power connection and a power controller (36) connected to the USB data hub (35), the power source (37) and the peripheral device (33). The power controller (36) receives instructions from the host device (31) to control the power source (37) to provide power to the peripheral device (33), communicates with the peripheral device (33) to determine parameters for power to be provided to the peripheral device (33), and controls the power source (37) to provide power at one of a plurality of different power levels to the peripheral device (33) via the power connection based on the instructions from the host device (31) and the determined parameters.

摘要： A method to composite image data into an image frame and transmit the image frame to a controller for display on a device. The image has a predetermined portion having a QoS requirement higher than the rest of the image. Based on a performance level of the system, the predetermined portion with the image data is composited into the image frame at the host device if the host device has sufficient performance capability. If the performance level is not sufficient, then the host device composites the image data without the predetermined portion and transmits it to the controller. The host device also transmits information regarding the predetermined portion to the controller independently of the image frame, so that the controller can composite the received image frame with the predetermined portion based on the information to produce the image for display.

摘要： Display data of a first type for a first display device is fetched from a first portion of a first buffer memory and display data of a second type is fetched from a first portion of a second buffer memory at a first time according to an arbitration control signal and then combined into display data for the first display device. Display data of the first type for the second display device is fetched from a second portion of the first buffer memory and display data of the second type for the second display device is fetched from a second portion of the second buffer memory at a second time according to the arbitration control signal, and then combined into display data for the second display device, which is multiplexed with the combined display data for the first display device into a single display data stream and output.

摘要： 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 (S1) compressed display data, store (S2) the received compressed display data in the frame buffer store, and for each frame refresh of the display device access (S3) stored compressed display data, decompress (S4) the accessed display data, and output S5 the decompressed display data.

摘要： A method of displaying application windows (18) on display devices (12) includes maintaining a designation of an application window as either public or private, maintaining a designation of a display device as either public or private, receiving an input directing the display of a private application window on a public display device, and preventing or adjusting the display of the private application window on the public display device, e.g. by obscuring the contents, blacking out a window, making a window invisible, or restricting a window from being dragged onto another display device.

摘要： A method of compensating for potential interruptions in a wireless spatially selective connection over which data at a first compression level is transmitted from a host device to a client device involves determining (S32) that an interruption to the wireless spatially selective connection over which data is being transmitted at a first compression level to a client device is starting or is due to start, compressing (S3Y3) the data at a second compression level that is higher than the first compression level, and forwarding (S34) the data compressed at the second compression level to a transmitting component for wireless spatially non-selective broadcast while the interruption to the spatially selective connection occurs. Determining that the interruption is due to start may involve analysing a historical record of previous interruptions to determine a periodicity of the previous interruptions or receiving information from the transmitting component that an interruption is expected to occur. Determining that the interruption is starting may involve determining that a buffer used for storing the data prior to transmittal is full, indicative that an interruption has commenced, or receiving information from the transmitting component that an interruption has commenced.

摘要： A method at a client device for mitigating motion judder in frames of an image due to display data for a particular frame being unavailable at a required time at the client device. The method involves receiving (S35) the display data for a current frame n, and generating (S3Y3) the current frame n from the received display data. Motion vectors for some elements of the image in the current frame n are obtained (S3Y1). If it is determined that display data for the next frame n+1 is not available, the next frame n+1 is generated (S3N4) from either the current frame n or a previous frame n−m, where m=1, 2, 3, etc, adjusted based on an extrapolation (S3N3) of the motion vectors for the elements of the image in either the current frame n or the previous frame n−m.

摘要： Disclosed herein is a method of writing data to, and reading data from, one or more buffers. The method comprises: determining a write rate of writing data into a first buffer; determining a read rate of reading data from the first buffer; determining, using the write rate and the read rate, a portion of the first buffer; writing data into the portion of the first buffer; starting to read data from the first buffer when the writing of data to the portion of the first buffer has finished; and writing data into a remaining part of the first buffer, different from the portion of the first buffer. The portion of the first buffer is determined such that the reading of data from the first buffer does not overtake the writing of data into the first buffer.

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.
