The present invention relates to a method for providing reliable motion vectors, comprising the steps of determining motion vectors between two image frames with backward and forward estimation, comparing backward estimation motion vectors and forward estimation motion vectors, and detecting unreliable motion vectors based on the comparison result. The present invention further relates to a system for providing reliable motion vectors.

The present invention relates to a method for providing a content stream () comprising processing information, comprising the steps of providing (S) content data () comprising image and/or audio data, acquiring (S) auxiliary data () from the content data () representing information for processing the content data () and embedding (S) the auxiliary data () into the content data () thereby providing said content stream (). The present invention further relates to such a content stream () and to a device for providing such a content stream (). Additionally, the present invention relates to a method and a device for processing a content stream () comprising processing information.

A method for interpolating a previous and subsequent image of an input image sequence, including: determining fidelity information for at least one motion vector that is descriptive for motion between a previous and subsequent image, wherein the fidelity information is descriptive for the level and accuracy of the motion, determining classification information for the at least one motion vector, wherein the classification information depends on the fidelity information, the classification information being descriptive for the motion type of the motion, and selecting an interpolation method in dependence of the determined classification information.

The present invention relates to a method for interpolating a subpixel at an interpolation position, which is situated in the chronological order between two source frames. Thereby the calculation of the interpolated subpixel's value is based on the value of the pixels of the two source frames and additional weighting coefficients, which are based on the motion vectors correlating the two source frames.

A system for storing and rendering multimedia data includes a first storage configured to store multimedia data files of a plurality of formats. The system also includes a second storage configured to store program files including information regarding a transformation of multimedia data files of a first format into multimedia data files of a second format, where the first format is one of the plurality of formats. The system also includes a rendering device configured to render multimedia data files of the second format. At least one of the multimedia data files stored in the first storage is linked to at least one of the program files, and the program file includes information regarding a transformation of multimedia data files of the format of the at least one of the multimedia data files into the second format.
