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： 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 method of compensating for potential interruptions in a wireless connection (110) over which data is transmitted from a host device (11) to a client device (12) involves determining an expectation of an interruption to the wireless connection (110), setting a second compression level for compressing the data when an interruption is due, the second compression level being set at a higher level than a first compression level normally used for the data, compressing the data at the second compression level, and forwarding the data compressed at the second compression level to a transmitting component (16) for transmittal to the client device (12). The expectation of a potential interruption may be determined by analysing a historical record of previous interruptions to determine a periodicity of the previous interruptions and using the determined periodicity to calculate when a next potential interruption may be expected, or by determining that a buffer used for storing the data prior to transmittal is full, indicative that an interruption has commenced, or by receipt of information from the transmitting component that a potential interruption is expected to occur or has commenced.

摘要： A method of processing image data for transmittal to a display device involves receiving a frame of image data, the frame being divided into tile groups composed of tiles of pixels, each having a number of colour component values of a first colour space. Each tile includes a number of colour component planes of the first colour space having the colour component values for the pixels forming the tile. Each tile group is processed in an execution unit, formed by arithmetic logic units (ALUs) and a local shared memory, where each ALU includes dedicated register space for use solely by the ALU, and each tile of each tile group is processed by a number of the ALUs of the execution unit. Each ALU performs a reversible colour transformation (S1) on the colour component values from the first colour space to a second colour space and discards the remaining colour component values and then performs a discrete wavelet transformation (S2) on the colour component values of one colour component plane of the second colour space to produce wavelet coefficients, which are quantized (S3) and entropy encoded (S4) into variable length codes. The variable length codes for all the tiles of the tile group are assembled together for transmittal to a display device. Each ALU stores the data at each stage of the processing in its dedicated register space but not in the local shared memory of the execution unit.

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 docking station configured to enable a host device to access resources provided by or connected to the docking station is disclosed. The resources include one or more peripheral devices, interfaces and/or network connections. The docking station is configured to receive setting information including at least one configuration setting for configuration of interaction between the host device and one or more of the resources. The docking station is also configured to transmit the setting information to the host device for use in configuring the host device to interact with one or more of the resources, when the host device communicatively couples to the docking station.
