A post-processing of video content in order to provide a capability to insert ad content, having a method to produce a modified video content from an original video content. The method comprising: analyzing the original video content to detect at least one marker, said marker comprising a marker surface delimited by a marker identification; loading profile data of a target user; determining, based at least on the profile data a replacement content; adjusting the replacement content into the marker surface; and replacing into the original video content the marker surface by the adjusted replacement content to produce the modified video content.

The disclosed computer-implemented method may include receiving, as an input, segmented video scenes, where each video scene includes a specified length of video content. The method may further include scanning the video scenes to identify objects within the video scene and also determining a relative importance value for the identified objects. The relative importance value may include an indication of which objects are to be included in a cropped version of the video scene. The method may also include generating a video crop that is to be applied to the video scene such that the resulting cropped version of the video scene includes those identified objects that are to be included based on the relative importance value. The method may also include applying the generated video crop to the video scene to produce the cropped version of the video scene. Various other methods, systems, and computer-readable media are also disclosed.

An example method performed by a processing system includes retrieving a digital model of a media element from a database storing a plurality of media elements, wherein the media element is to be inserted into a scene of an audiovisual media, rendering the media element in the scene of the audiovisual media, based on the digital model of the media element and on metadata associated with the digital model to produce a rendered media element, wherein the metadata describes a characteristic of the media element and a limit on the characteristic, and inserting the rendered media element into the scene of the audiovisual media.

An encoding method and a decoding method. The encoding method includes generating curved image by creating projection of visual scene onto inner surface of imaginary 3D geometric shape that is curved in at least one dimension; dividing curved image into input portion and plurality of input rings; encoding input portion and input rings into first planar image and second planar image, respectively, such that input portion is stored into first planar image, and input rings are packed into corresponding rows of second planar image; and communicating, to display apparatus, first and second planar images and information indicative of sizes of input portion and input rings.

The techniques described herein relate to methods, apparatus, and computer readable media configured to perform media processing tasks. A media processing entity includes a processor in communication with a memory, wherein the memory stores computer-readable instructions that, when executed by the processor, cause the processor to perform receiving, from a remote computing device, multi-view multimedia data comprising a hierarchical track structure comprising at least a first track comprising first media data at a first level of the hierarchical track structure, and a second track comprising task instruction data at a second level in the hierarchical track structure that is different than the first level of the first track. The instructions further cause the processor to perform processing the first media data of the first track based on the task instruction data of the second track to generate modified media data and an output track that includes the modified media data.

The present disclosure relates to a method and device for transmitting and receiving video content including three-dimensional (3D) data. The method of transmitting video content through a plurality of assets includes identifying whether content transmitted through an asset is a sub-picture; when the content transmitted through the asset is the sub-picture, generating sub-picture asset information comprising information about other sub-pictures constituting a composition picture together with the sub-picture; and transmitting the sub-picture asset information and the content.

A method, computer program, and computer system is provided for splitting viewport bitstreams. A first coded video bitstream is at least partially encoded using a first Group-of-Pictures (GOP) structure at a first resolution. A second coded video bitstream structured into a plurality of tiles is encoded using a second GOP structure at a second resolution, whereby the second GOP structure includes fewer coded pictures than the first GOP structure. A streaming bitstream for decoding or rendering is created using the first coded video bitstream and the second coded bitstream.

Techniques and mechanisms described herein facilitate providing dynamic digital object placement in a video stream. An exchange network for engagements within video streaming content is maintained, and a number of engagement entities and content providers are connected to the exchange network. An engagement proposal is received from an engagement entity in the exchange network, containing media assets for an engagement and proposed engagement information. Content provider requirements are also received from a content provider in the exchange network, containing content provider requirements and one or more engagement surfaces associated with a video stream. The exchange network determines that the received engagement proposal matches the received content provider requirements. Once the exchange network matches the two entities, the media assets from the engagement entity are dynamically inserted into the video stream published by the content provider by mapping the media assets to the one or more engagement surfaces.

A 360 image data processing method performed by a 360 video receiving device, according to the present invention, comprises the steps of: receiving 360 image data; acquiring information and metadata on an encoded picture from the 360 image data; decoding the picture on the basis of the information on the encoded picture; and rendering the decoded picture and an overlay on the basis of the metadata, wherein the metadata includes overlay-related metadata, the overlay is rendered on the basis of the overlay-related metadata, and the overlay-related metadata includes information on a region of the overlay.

A system and method for providing quality control in immersive video during pausing of a video streaming session. In one embodiment, a paused video frame may comprise a plurality of mixed quality video tiles depending on user gaze vector information. Under pause control, the video quality of all tiles of the paused video frame is equalized such that it is of same value for all the video tiles, which may be the video quality of the tiles presented in a viewport of the client device. The paused video frame having the same quality tiles throughout is used as a replacement video frame, which is presented to the client device player for decoding and displaying instead of the mixed quality video frame while the streaming session is paused.
