Abstract: A video processing method includes performing a conversion between a video block of a video and a coded representation of the video. The coded representation conforms to a format rule. The format rule specifies that applicability of a transform skip mode to the video block is determined by a coding condition of the video block. The format rule also specifies that a syntax element indicative of applicability of the transform skip mode is omitted from the coded representation. The transform skip mode includes skipping applying a forward transform to at least some coefficients prior to encoding into the coded representation, or during decoding, skipping applying an inverse transform to at least some coefficients prior to decoding from the coded representation.

Abstract: Devices, systems, and methods for lossless coding for visual media coding are described. An exemplary method for video processing includes determining, based on a current video block of a video satisfying a dimension constraint, that coding modes are enabled for representing the current video block in a bitstream representation, where the dimension constraint states that a same set of allowed dimensions for the current video block is disabled for the coding modes, and where, for an encoding operation, the coding modes represent the current video block in the bitstream representation without using a transform operation, or where, for a decoding operation, the coding modes are used to obtain the current video block without using an inverse transform operation; and performing a conversion between the current video block and the bitstream representation of the video based on one of the coding modes.

Abstract: Methods, apparatuses, and computer program products are provided herein for improving consumer interactions with Marketing and Promotion Service systems. In one embodiment, a method for searching for promotions is provided which includes accessing a map to be displayed to a consumer; receiving input comprising a time period; and receiving input comprising a circumscribed region on a map, wherein the circumscribed region provides an indication of an area in which the consumer is planning to travel. The method further includes searching, by a processor, for promotions within the circumscribed region that are redeemable during the time period and generating an impression comprising one or more promotions returned from the searching for promotions, wherein the impression includes at least one promotion related to travel. A corresponding apparatus and computer program product are also provided.

Abstract: Embodiments of the present disclosure provide a solution for media processing. A method for media processing comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein each main stream representation (MSR) in the media presentation is associated with an external stream representation (ESR) in the media presentation. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.

Abstract: Embodiments of the present disclosure provide a solution for media processing. A method for media processing is proposed. The method comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein the media presentation comprises a main stream representation (MSR) and an external stream representation (ESR) associated with the MSR, a concatenation of a first segment in the ESR, a second segment in the MSR corresponding to the first segment, and subsequent segments following the second segment in the MSR results in a file conforming to a file format standard. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.

Abstract: A method of video processing includes: determining an affine mode type to be applied to a current block coded in an affine mode in a video frame, wherein the current block is split into a plurality of sub-blocks; and deriving motion information for each of the plurality of sub-blocks based on the affine mode type, at least one control point (CP) motion vector (MV) at a specific location being derived and stored for predicting other blocks to be processed subsequently.

Abstract: A method of visual media processing includes determining, for a conversion between a current video block of visual media data and a bitstream representation of the current video block, a buffer that stores reference samples for prediction in an intra block copy mode; for a sample spatially located at location of the current video block relative to an upper-left position of a coding tree unit including the current video block and having a block vector, computing a corresponding reference in the buffer at a reference location, wherein the reference location is determined using the block vector and the location; and upon determining that the reference location lies outside the buffer, re-computing the reference location based at least in part on a location of the current video block relative to the coding tree unit including the current video block.

Abstract: Embodiments of the present disclosure provide a method for video processing. The method comprises: determining, during a conversion between a current video block of a video and a bitstream of the video, whether to insert a target motion candidate for the current video block into a prediction list for the current video block based on a comparison between the target motion candidate and at least one existing motion candidate in the prediction list; and performing the conversion based on the determination. The proposed method can advantageously fill the prediction list more efficiently.
