The embodiments relate to a method at a sender device, the method including receiving, as a response to a delivered indication of a number of supported subpictures, from a receiver an indication on a number of subpictures allowed in an encoded image data; partitioning a bitstream representing an image data into subpictures, the amount of which corresponds to the indicated number of subpictures; generating an encoded bitstream including said subpictures; delivering the encoded bitstream to a receiver apparatus; and delivering required parameter sets for said subpictures to said receiver apparatus. The embodiments also concern a method at a receiver device, and corresponding devices.

A method of providing a menu for accessing media assets may include defining an media asset menu, defining an media asset menu item, the menu item including visibility criteria, adding the menu item to the defined menu, storing the defined menu, and distributing the stored menu to client devices over a network. A method of providing a menu for accessing media assets may include defining a new a menu for accessing media assets, loading a menu template from storage, the loaded menu template comprising a plurality of menu items, for each menu item among the plurality of menu items, determining if visibility criteria specified for the menu item are met, upon determining that the visibility criteria specified for the menu item are met, adding the menu item to the menu, otherwise excluding the menu item from the menu, and displaying the menu.

A media presentation and distribution system communicatively coupled to a client device is provided. The client device receives a media stream from the media presentation and distribution system via a network. The media stream includes media content and one or more tags. The client device further identifies in the received media content, the one or more tags, which corresponds to the overlay-graphic items. The client device further identifies candidate time-periods in the media content based on the one or more tags in the media content. At least one presentation attribute for the overlay-graphic items is identified based on the one or more tags in the media content. The client device further presents the overlay-graphic items at the candidate time-periods on the media content based on a degree of correlation between the identified tag in the media content and a corresponding context for the media content at the candidate time-period.

Methods and systems for calculating, storing, and allowing electronic searches for metadata associated with media titles. The metadata includes scores specific to each actor and each genre of a media title, where the scores indicate the degree to which an actor's performance in that title corresponds to a particular genre. Electronic searches for particular actors' performance in a specific genre thus return more accurate results that more correctly reflect how well the actors' performances reflect that genre.

One or more frames sampled from a first media item of an event are analyzed to identify one or more candidate event periods within the one or more frames. For each of the one or more frames, whether a candidate event period of the one or more candidate event periods satisfies one or more conditions is determined. Responsive to determining that the candidate event period of the one or more candidate event periods satisfies the one or more conditions, the candidate event period is identified as an actual event period used to divide a time the event. Mapping data that maps the actual event period to a timestamp associated with a respective frame of the one or more frames of the first media item is generated.

A system for broadcasting that includes a watermark payload.

A method for encapsulating media data into an ISO Base Media File Format (ISOBMFF) standard compliant file, the media data comprising a sequence of samples, including obtaining at least one sample of the sequence, generating ISOBMFF structure data indexing the at least one obtained sample, compressing the at least one obtained sample, and embedding the generated ISOBMFF structure data and the compressed at least one sample within the ISOBMFF compliant file.

Systems and methods for matching videos to podcast episodes are provided. A data store comprising podcast episode identifiers is accessed. The podcast episode identifiers are associated with one or more podcast episode attributes. A video content item is identified. The video content item includes one or more video content item attributes. A matching podcast episode identifier that matches the video content item is determined based on the one or more podcast episode attributes and the one or more video content item attributes. A ranking of one of the video content item or the matching podcast episode identifier is caused to be adjusted to reflect the correspondence between the video content item and the matching podcast episode identifier. Information associated with the matching podcast episode identifier is provided to a first user device.

Various embodiments described herein support or provide for cultural distance prediction operations of a media asset, such as determining events in a media asset, determining geographical region corresponding to the culture of origin and the culture of destination, accessing weight values of cultural attribute categories respectively associated with the geographical regions of the culture of origin and the culture of destination, generating cultural distance score of events, and causing display of the cultural distance score on a user interface of a client device.

Aspects discussed herein relate to systems, apparatuses, and methods to identify points of interest of viewers of a content item concurrently being transmitted in a linear stream to the viewers. A point of interest may refer to a segment of the content item that caused a surge in user reactions. During a subsequent transmission of the content item, identified points of interests may be displayed to the viewer. The viewer may select the point of interest in the content item to begin playback of the point of interest in the content item.
