  • Publication number: 20090034619
    Abstract: Techniques for adapting an encoded video signal to a complexity of video encoding may be used to reduce a bit rate of an encoded video signal when the complexity is reduced. Video communication according to the present techniques includes adapting an encoded video signal to an encoding complexity used to derive a set of encoded data from a series of video frames.

  • Publication number: 20070247547
    Abstract: A method for performing motion compensated video spatial up-conversion on video. The horizontal samples in successive fields are first interpolated using a spatial interpolation technique. This is followed by interpolating the corresponding vertical samples using a motion compensated deinterlacing technique. Such techniques can include an adaptively recursive motion compensated video spatial up-conversion or an adaptively recursive motion compensated video spatial up-conversion using a generalized sampling theorem. The present invention can be used to convert video captured on a mobile device, such as a mobile telephone, so that it can be subsequently and adequately displayed on a television.

  • Publication number: 20070025441
    Abstract: In general, a methodology of rate control for a video encoding is provided, which is implementable by the means of a method, a device, a computer program and/or a video encoder. A frame encoding process is performed for each frame in that an initial quantization parameter is calculated for being used as a quantization parameter for encoding a current frame. Each group of macroblocks within the current frame is encoded group by group; i.e. group-wise. A score value is determined after macroblock encoding of a current group of macroblocks. In case the score value exceeds a pre-defined threshold, the quantization parameter for encoding the next group of macroblocks is adjusted; otherwise, the macroblock encoding is continued with the quantization parameter which is currently used for encoding the current group of macroblocks.
