摘要： Computer program products and a mobile terminal for transmitting and receiving video data. Image data of first and second frames of a video signal captured by a camera is used to determine encoded first spatial units of the first frame and encoded second spatial units of the second frame at lower spatial resolution, which are transmitted to the receiver terminal. The second spatial units are unaligned with the first spatial units due to rotation of the camera between the first and second frames, such that each of the second spatial units partially overlaps with at least one first spatial unit. An indication of the angle of rotation of the camera between the first and second frames is detected using a rotational motion sensor and transmitted to the receiver terminal. The receiver terminal combines the first and second spatial units using the indication to reconstruct an image of higher spatial resolution.

摘要： An input receives a video signal comprising a plurality of frames of a video image, each frame comprising a plurality of higher resolution samples. A projection generator generates a different respective projection of each of a sequence of the frames, each projection comprising a plurality of lower resolution samples, wherein the lower resolution samples of the different projections represent different but overlapping groups of the higher resolution samples which overlap spatially in a plane of the video image. Inter frame prediction coding is performed between the projections of different ones of the frames based on a motion vector for each prediction. The motion vector is scaled down from a higher resolution scale corresponding to the higher resolution samples to a lower resolution scale corresponding to the lower resolution samples. An indication of a rounding error resulting from this scaling is determined and signalled to the receiving terminal.

摘要： A receiver receives a video bitstream from an encoder, comprising encoded image portions each having a common form representing components of a channel in a color space. Each of a plurality of the encoded image portions comprises a different set of quantized values of the components, including values of one or more first ones of the components quantized according to a first scheme. The received bitstream further comprises, for each of the one or more first components, an indication of one or more characteristic points in a respective quantization level distribution according to the first scheme, but fewer points per distribution than there are quantized levels of the respective distribution. A de-quantizer at least partially de-quantizes the different quantized values of that first component using the points of the respective distribution, by reconstructing the distribution from those points.

摘要： A video bitstream is received from an encoder, comprising encoded image portions each having a common form representing components of a channel in a colour space. Each of a plurality of the encoded image portions comprises a different set of quantized values of the components, including at least a value of a first of the components being quantized from amongst a first scheme of quantized levels. Further, the received bitstream comprises a look-up table mapping the quantized levels of the first scheme to at least partially de- quantized respective levels. A de-quantizer uses the look-up table received in the bitstream to at least partially de-quantize the different quantized values of the first component in a plurality of the image portions, by converting the quantized values of the first component to at least partially de-quantized values corresponding to ones of the at least partially de- quantized levels of the first scheme.
