Abstract: A data rate controlling feedback loop evaluates an actual instantaneous available quality of service of a communication link for transmitting data and controls the data rate based on an evaluation result, Feedback control may both be local to a device for acquiring examination data, such as a magnetic resonance imaging coil, or over the communication link by reducing the data rate at least momentarily to fit the communication link's performance over time, enabling a graceful degradation of an image quality at lower data rates.

Abstract: A method is provided of processing image data for display by a display panel of a display device. The method comprises receiving main image pixel data representing a main image and side image pixel data representing a side image, and performing a mapping of the pixel data to signals used to drive the display panel. The mapping is arranged to produce an average on-axis luminance which is dependent mainly on the main image pixel data and an average off-axis luminance which is dependent at least to some extent on the side image pixel data. A compression of the main image pixel data is performed in advance of or at least partly incorporated into the mapping, the compression being performed at least partly in dependence upon the main image pixel data and at least partly in dependence upon how the off-axis luminance varies with pixel data input to the mapping.

Abstract: A radio frequency antenna comprising a resonant pickup circuit (102) arranged to pick up a magnetic resonance signal, an analog-to-digital converter (105) arranged to convert the magnetic resonance signal to digital data, and a frequency converter arranged to convert a primary band of frequencies of the digital data. By upshifting the frequency of the transmitted bit-stream, it is possible to RF-trap the transmission channel (109) by simple high-pass filtering techniques. In case the transmitted bit pattern has frequency components that approach the resonance frequency, an encoding technique like Manchester encoding can be used to eliminate unwanted signals.

Abstract: A method is provided for performing robust frame rate conversion of video data to a higher frame rate. A metric is formed (16) as a function of motion compensation error normalised by a measure of image content, such as image texture (10, 11). The metric is then compared with thresholds (17, 18) to determine whether conversion will be based on motion compensated interpolation or frame repetition. If the metric falls between thresholds, the previously selected mode may be repeated.
