20210058644 | Deblocking Filtering - A method of reducing blocking artifacts associated with pixels of a block boundary of an image. Pixel values of pixels from a first block and a neighboring block, being located on opposite sides of a block boundary, are evaluated. A first offset for the two pixels of each block located next to the block boundary is calculated, after which the first offset is compared to a first threshold value. If abs[first offset]=first threshold, the pixel values of consecutive pixels from the first block and the pixel values of consecutive pixels from the second block are modified by applying weak filtering or no filtering at all on the respective pixels. | 2021-02-25 |
20210058645 | DELAYED DUPLICATE I-PICTURE FOR VIDEO CODING - A method is provided that includes receiving pictures of a video sequence in a video encoder, and encoding the pictures to generate a compressed video bit stream that is transmitted to a video decoder in real-time, wherein encoding the pictures includes selecting a picture to be encoded as a delayed duplicate intra-predicted picture (DDI), wherein the picture would otherwise be encoded as an inter-predicted picture (P-picture), encoding the picture as an intra-predicted picture (I-picture) to generate the DDI, wherein the I-picture is reconstructed and stored for use as a reference picture for a decoder refresh picture, transmitting the DDI to the video decoder in non-real time, selecting a subsequent picture to be encoded as the decoder refresh picture, and encoding the subsequent picture in the compressed bit stream as the decoder refresh picture, wherein the subsequent P-picture is encoded as a P-picture predicted using the reference picture. | 2021-02-25 |
20210058646 | VIDEO SIGNAL PROCESSING METHOD AND DEVICE - According to the present invention, there is provided a video signal processing method of dividing an input image on a per-block basis for encoding, the method including: determining, at a division determination step, whether to divide a current block; dividing, at a block division step, the current block into multiple sub blocks on the basis of the determination; generating block division information on division of the current block; and encoding, at an encoding step, the block division information, the current block, or the sub blocks. Examples of division of the block according to the present invention include division using N-ary tree structures, such as the quad tree structure, the binary tree structure, and/or the triple tree structure. | 2021-02-25 |
20210058647 | MAIN CONCEPT OF EQT, UNEQUALLY FOUR PARTITIONS AND SIGNALING - Methods, systems and devices for using flexible and efficient partitioning techniques are described. An exemplary method for visual media decoding includes applying, to a current visual media block, a partitioning process that splits the current visual media block into exactly four sub-blocks including at least one sub-block that has a size different from half of a width of the current visual media block times half of a height of the current visual media block, decoding, based on a bitstream representation, the four sub-blocks, and decoding, based on the four sub-blocks and the partitioning process, the current visual media block. | 2021-02-25 |
20210058648 | METHOD OF RECORDING, IN A MASS MEMORY OF AN ELECTRONIC DEVICE, AT LEAST ONE MULTIMEDIA CONTENT - Method of recording a multimedia content broadcast streamwise, comprising the following steps: initialize a current throughput of recording of the stream in a mass memory; acquire a current portion of the multimedia content at the current recording throughput, and store it temporarily in the buffer memory; evaluate a rate of fill of the buffer memory; if the fill rate is greater than a predetermined high threshold of fill, decrease the current recording throughput; if the fill rate is less than or equal to a predetermined low threshold, increase the current recording throughput. | 2021-02-25 |
