Abstract: The present invention relates to a method for compressing genomic data, whereby the genomic data are stored in at least one data file containing at least a plurality of reads built by a genome sequencing method, whereby each read includes a mapping position, a CIGAR string and an actual sequenced nucleotide sequence as a local part of the donor genome, comprising the steps: —unwind a nucleotide sequence of a current read of one of said data files by using the mapping position and the CIGAR string of said current read, whereby said current read has at least one previous read, —compute a difference between the unwound nucleotide sequence of said current read and an unwound nucleotide sequence of at least one of said previous reads, whereby said difference contains the differences of the mapping positions and the nucleotide sequences, —pass said computed difference to an entropy coder to compress said difference, —encode said current read by the compressed difference, and —repeat the forgoing steps with said cur

Abstract: Coding of screen content includes identifying corresponding areas in one or more previously coded frames to code unchanged areas in current frames. An unchanged area in a current frame is coded by copying a corresponding area from a previously coded frame or several previously coded frames. Usage of a copy mode to be applied to the unchanged areas is signaled in an encoding bitstream. The copy mode can be signaled for each unchanged area or a single copy mode is signaled for a group of unchanged areas. The copy mode can be automatically applied to one or more unchanged areas contiguous to the group of unchanged areas without further signaling the copy mode. Copying the corresponding area from the previously coded frame includes copying palette entries from the previously coded frame. Palette entries copied from the previously coded frame are reordered according to frequency of appearance.

Abstract: An apparatus comprising a processor configured to obtain mixed content video comprising images comprising computer generated screen content (SC) and natural content (NC), partition the images into SC areas and NC areas, and encode the images by encoding the SC areas with SC coding tools and encoding the NC areas with NC coding tools, and a transmitter coupled to the processor, wherein the transmitter is configured to transmit data to a client device, the data comprising the encoded images and an indication of boundaries of the partition.

Abstract: A device for synchronizing an audio signal with a film comprising frames having imprinted time codes. A detector detects the imprinted time code for the sequence of frames to obtain a detected sequence of time codes. A time code generator generates a sequence of synthesis time codes based on an initial value. A decoder decodes a time code of the detected sequence of time codes obtain the initial value. A comparator compares a detected time code and a corresponding synthesis time code and, when a phase deviation is found to be above a deviation threshold value, a time code manipulator manipulates the synthesis time code for this frame in so far that it is changed with regard to its temporal length. An audio processor provides the samples of the audio signal associated with this frame in a time-controlled way in response to a detection of the synthesis time code for a frame.

Abstract: A device for synchronizing an audio signal with a film comprising frames, wherein each frame comprises an imprinted time code, includes means for detecting the imprinted time code for the sequence of frames in order to obtain a detected sequence of time codes. Further, a time code generator is provided which is implemented to generate a sequence of synthesis time codes based on an initial value. A decoder is further provided to decode a time code of the detected sequence of time codes in order to provide the initial value for the time code generator. A detected time code and a corresponding synthesis time code are compared in order to then, when a phase deviation is found to be above a deviation threshold value, manipulate the synthesis time code for this frame in so far that it is changed with regard to its temporal length.
