Abstract: The precision of up-sampling operations in a layered coding system is preserved when operating on video data with high bit-depth. In response to bit-depth requirements of the video coding or decoding system, scaling and rounding parameters are determined for a separable up-scaling filter. Input data are first filtered across a first spatial direction using a first rounding parameter to generate first up-sampled data. First intermediate data are generated by scaling the first up-sampled data using a first shift parameter. The intermediate data are then filtered across a second spatial direction using a second rounding parameter to generate second up-sampled data. Second intermediate data are generated by scaling the second up-sampled data using a second shift parameter. Final up-sampled data may be generated by clipping the second intermediate data.

If, while information on the speed limit indicated by the speed limit sign is displayed, the speed limit information is obtained, and the speed limit determined by the obtained speed limit information is different from the speed limit determined by the previously obtained speed limit information, the display control unit shows information on the speed limit determined by the presently obtained speed limit information.

Abstract: A video encoder and decoder are described. The encoder operates on luma data and chroma data. The luma data is split into two channels. The channel split can be based on frequency regions or based on even and odd lines. When the channel split is based on frequency regions, the encoder produces a channel with low frequency data and a channel with high frequency data. A third channel holds chroma data. The decoder recovers the split luma data and the third channel of chroma data. The decoder may then generate one or more pixels to be stored in a line buffer.

Abstract: An idea used herein is to use the same function for the dependency of the context and the dependency of the symbolization parameter on previously coded/decoded transform coefficients. Using the same function—with varying function parameter—may even be used with respect to different transform block sizes and/or frequency portions of the transform blocks in case of the transform coefficients being spatially arranged in transform blocks. A further variant of this idea is to use the same function for the dependency of a symbolization parameter on previously coded/decoded transform coefficients for different sizes of the current transform coefficient's transform block, different information component types of the current transform coefficient's transform block and/or different frequency portions the current transform coefficient is located within the transform block.

Abstract: A plurality of captured images obtained by repeatedly shooting a rotating object are obtained. In a case where a feature point corresponding to a certain point on the object is specified in one captured image and another captured image, a position information obtaining unit obtains position information relating to a position of the feature point in the one captured image and the another captured image. A rotation angle information obtaining unit obtains rotation angle information relating to a rotation angle of the object between a point of time when the one captured image is shot and a point of time when the another captured image is shot based on position information. A moving image data generating unit generates moving image data by selecting frame images of the moving image data from the plurality of photographed images based on rotation angle information of each of the plurality of photographed images.

Abstract: A subblock-based coding of transform coefficient blocks of the enhancement layer is rendered more efficient. To this end, the subblock subdivision of the respective transform coefficient block is controlled on the basis of the base layer residual signal or the base layer signal. In particular, by exploiting the respective base layer hint, the subblocks may be made longer along a spatial frequency axis transverse to edge extensions observable from the base layer residual signal or the base layer signal.

Abstract: Scalable video coding is rendered more efficient by deriving/selecting a subblock subdivision to be used for enhancement layer prediction, among a set of possible subblock subdivisions of an enhancement layer block by evaluating the spatial variation of the base layer coding parameters over the base layer signal. By this measure, less of the signalization overhead has to be spent on signaling this subblock subdivision within the enhancement layer data stream, if any. The subblock subdivision thus selected may be used in predictively coding/decoding the enhancement layer signal.
