Abstract: Colour conversion apparatus comprises mapping circuitry configured to map pixels of an input image having colour components in an input colour space to pixels of an mapped image having colour components in an output colour space, the input colour space and the output colour space being different colour spaces such that at least a subset of colours representable in the input colour space are not representable in the output colour space; the mapping circuitry being configured to: convert pixels from the input colour space to an intermediate colour space in which a colour space representation of hue approximates to a consistent perceived hue independent of brightness and/or saturation; map pixels in the intermediate colour space which lie outside a region of the intermediate colour space corresponding to representable colours in the output colour space to generate mapped pixels so that the mapped pixels lie within that region, by varying the brightness and/or saturation of those pixels in the intermediate colour

Abstract: Systems, apparatuses, and methods for adjusting the compression level for blocks of a frame based on a distance of each block to the focus region are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter compresses frames of the video stream prior to sending the frames to the receiver. For each block of pixels of a frame, the transmitter selects a compression level to apply to the block based on the distance from the block to the focus region, with the compression level increasing the further the block is from the focus region. The focus region is the portion of a half frame where each eye is expected to be focusing when viewed by a user. The transmitter encodes each block with the selected compression level and then conveys the encoded blocks to a receiver to be displayed.

Abstract: A drive circuit (100) for driving actuators of a printhead (97) from a common drive waveform has a switching circuit (32) for coupling the common drive waveform to an actuator (1,2), and a timing circuit (10) to control the switching circuit to form a drive pulse from the common drive waveform. The drive pulse is trimmed by controlling a duration (TTRIM) of a step at an intermediate level (VHOLD) in the drive pulse. This can improve the trade-off between available range of trimming and thermal efficiency because the voltage drop across the switching circuit can be reduced, compared to trimming only the height. Decoupling during a flat portion of the common drive waveform can enable the timing of the decoupling to be more relaxed compared to decoupling during a slope. Such relaxing can enable costs, complexity and thermal loading to be reduced.

Abstract: Systems and methods are disclosed for delivering programming content to vehicles (e.g., seagoing vessels) in a cost-effective manner. In some embodiments, programming content may be delivered to vehicles over previously deployed networks (e.g., satellite networks), using excess network capacity which may not otherwise be used to deliver data. By opportunistically employing excess network capacity (e.g., as the capacity becomes available), data constituting programming content may be delivered to vehicles over a period of time, such as via multicast transmission. A vehicle may store received data on one or more onboard servers. After an item of programming content has been received, the item may be made accessible to the vehicle's crew and/or passengers, such as by streaming the item to one or more suitably configured playback devices. Content may be served to playback devices “on demand” and/or according to a programming schedule.
