Abstract: A media composition application, such as a musical scorewriter or a digital audio workstation, provides in situ suggestions for continuation or completion of a media composition. The suggestions are based on some or all of the portion of the composition already composed or are based on a corpus of compositions, such as those by a particular composer or those of a specific genre. The length of the suggestions is specified by the user. The suggestions are provided within a graphical user interface of the application and displayed as a possible direct continuation of the composition within a musical stave. If the user rejects the suggestion, additional suggestions are automatically displayed in situ. Reductive, most-probable suggestions may be offered as well as exploratory suggestions that facilitate a creative compositional interaction between user and application. Data filters enable selected aspects of a data source to be used for suggestion generation.

Abstract: A video decoding method performed by a video decoding device according to the present document comprises the steps of: parsing a flag pertaining to a weighted prediction from a bitstream; parsing the syntax of a prediction weighted table from the bitstream based on the flag; performing a weighted prediction for the current block in the current picture based on the prediction weighted table syntax to generate prediction samples for the current block; generating residual samples based on residual information acquired from the bitstream; and generating reconstructed samples for the current block based on the prediction samples and the residual samples, wherein the prediction weighted table syntax can be parsed from the picture header of the bitstream based on the value of the flag being 1, and can be parsed from the slice header of the bitstream based on the value of the flag being 0.

Abstract: Disclosed is a method and chip for vertically filtering an image, including: caching and reading image data; calling a filter to vertically filter the image data to obtain first filtered data; updating the image data according to the first filtered data, and judging whether a to-be-read row is the last row of the image data; if not, updating the to-be-read row to the next row of the to-be-read row, and returning to execute the step of caching the image data; and if so, determining the vertically filtered image data. In the present application, point-by-point feedback is changed to row-by-row feedback according to an algorithm principle of a digital recursive filter and the characteristics of an image chip.

Abstract: Systems and methods for editing a media composition from media assets are provided. An editing device receives a media asset associated with a scene to be rendered in a media composition. The editing device receives a script including script elements that index script sections associated with the scene and metadata. The editing device edits the media composition with segments of the media asset based on a comparison of the segments, the script elements, and the metadata.

Abstract: A method of decoding video data, that method includes: receiving a picture parameter set; parsing a first syntax element specifying whether in-loop filtering operations may be performed for pictures in the picture parameter set, in a case that a number of tiles in a picture is greater than 1, and parsing a second syntax element specifying whether a raster-san slice mode or a rectangular slice mode is in use and whether slice information is signaled in the picture parameter set, in the case that the number of tiles in the picture is greater than 1.

Abstract: There are provided a method and apparatus for illumination and color compensation for multi-view video coding. A video encoder includes an encoder for encoding a picture by enabling color compensation of at least one color component in a prediction of the picture based upon a correlation factor relating to color data between the picture and another picture. The picture and the other picture have different view points and both corresponding to multi-view content for a same or similar scene.

Abstract: A sequence of tuples, each having one or more attributes, is received at one of one or more processing elements operating on one or more processors. Each processing element may have one or more stream operators. A first stream operator may be identified as one that only processes an instance of a first attribute in a currently received tuple when a difference between an instance of the first attribute in a previously received tuple and the instance of the first attribute in the currently received tuple is outside of a difference threshold. A second stream operator may generate a difference attribute from a first instance of the first attribute in a first one of the received tuples and a second instance of the first attribute in a second one of the received tuples. The difference attribute may be transmitted from the second stream operator to the first stream operator.
