Abstract: A format for use in encoding moving image data, comprising: a sequence of frames including plurality of the frames in which at least a region is encoded using motion estimation; a respective set of motion vector values representing motion vectors of the motion estimation for each respective one of these frames or each respective one of one or more regions within each of such frames; and at least one respective indicator associated with each of the respective frames or regions, indicating whether the respective motion vector values of the respective frame or region are encoded at a first resolution or a second resolution.

Abstract: Method, device and computer program product for estimating quality of a video signal, wherein frames of the video signal are received at receiving means of the device, each frame comprising a plurality of blocks of pixels. A section of a first frame of the video signal, which is correctly received, is used to provide a concealed block for use in place of a block of a second frame of the video signal. A difference measure is determined indicative of a difference between at least some of the pixels surrounding the block in the second frame and the corresponding pixels surrounding the section in the first frame. The difference measure is used to estimate the quality of the second frame of the video signal.

Abstract: An input of an encoder receives moving image data comprising a sequence of frames to be encoded, each frame comprising a plurality of blocks in two dimensions with each block comprising a plurality of pixels in those two dimensions. A motion prediction module performs encoding by, for at least part of each of a plurality of said frames, coding each block relative to a respective reference portion of another frame of the sequence, with the respective reference portion being offset from the block by a respective motion vector. According to the present disclosure, the moving image data of this plurality of frames comprises a screen capture stream, and the motion prediction module is configured to restrict each of the motion vectors of the screen capture stream to an integer number of pixels in at least one of said dimensions.
