  • Publication number: 20210409707
    Abstract: An apparatus for decoding a picture is configured to partition the picture into coding blocks, using recursive multi-tree splitting. Splitting schemes for the multi-tree splitting are described. According to an embodiment, the decoder decodes a split direction flag from a data stream by context adaptive entropy decoding using a context which depends on whether, and discriminates be-tween, a first number of criteria which would be fulfilled in case of a split direction indicated by the split direction flag being horizontal equals a second number of criteria which would be fulfilled in case of the split direction indicated by the split direction flag being vertical, the first number being greater than the second number, and the first number being smaller than the second number.

  • Publication number: 20210368176
    Abstract: An apparatus for decoding a picture using predictive coding and block-based transform residual coding. The apparatus is configured to select, for a predetermined transform block, a transformation dependent on a size of the predetermined transform block. If the size of the predetermined transform block exceeds a predetermined threshold size, the apparatus is configured to use a default way for selecting the selected transformation.

  • Publication number: 20210084313
    Abstract: The refinement of block-based predictive coding and decoding of pictures as applicable in, e.g., hybrid video codecs, using additional reconstructed samples or residuals is described. An apparatus for block-based predictive decoding of a picture is described. The apparatus includes a combiner configured to combine a residual signal a predetermined block of the picture and a reference signal for the predetermined block so as to obtain a first spectrum, the residual signal correcting a prediction error of a prediction of the predetermined block of the picture; a reducer configured to perform thresholding on the first spectrum to obtain a second spectrum so that coefficients below a threshold value are set to a predefined value; an extractor configured to obtain from the second spectrum a modified version of the residual signal; and a reconstructor block configured to decode the predetermined block of the picture from the data stream on the basis of the modified version of the residual signal.

  • Publication number: 20210084304
    Abstract: The coding of a media signal is rendered more efficient by describing the media signal using a sequence of samples and sequentially encoding this sequence by selecting, for a current sample, a set of quantization levels out of a plurality of quantization level sets depending on indices encoded into the data stream for previous samples of the sequence of samples, quantizing the current sample onto one level of the set of quantization levels, and encoding a quantization index to the one level for the current sample into the data stream. In other words, scalar quantization of the individual samples of the sequence of samples is used, but it is rendered dependent on quantization indices encoded into the data stream for previous samples of the sequence of samples.

  • Patent number: 9391800
    Abstract: Systems, methods, apparatuses, and computer program products are described herein that enable a computing device to dynamically generate virtual private network (VPN) connection profiles to which policies can be mapped and then subsequently enforced. The VPN connection profiles are dynamically generated by a translation engine by obtaining parameters from payloads received from a plurality of different VPN gateways pursuant to establishing connections therewith in accordance with a respective plurality of different tunneling protocols, which may include both standard and proprietary tunneling protocols. The dynamically-generated VPN connection profiles are then provided to a connection manager, which enforces any policies associated with the VPN connection profiles when servicing requests for connections received from applications running on the computing device.
