The disclosure relates to a method and an apparatus for dynamic scene updates (scenes including timed media) requiring extensions to scene description patch documents supporting timed media. A method for timed and event triggered updates in a scene description for extended reality (XR) multimedia is provided. The method includes parsing a scene description and at least one scene update track sample in a timed scene description update track or at least one scene update item to update the scene description and rendering the updated scene description on a display.

Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method includes receiving media files comprising video or audio data captured at a production stage and determining a hierarchical structure of the multimedia content based on production stage information of the multimedia content. The hierarchical structure indicates that the multimedia content comprises multiple scenes, each of which comprises multiple shots produced with corresponding devices and cast. The method also includes identifying characteristics associated with the individual scenes based on the production stage information, generating multiple copies of the multimedia content at different compression levels, and dividing each of the multiple copies of the multimedia content into segments based on the hierarchical structure. The compression levels and a length of a segment are adaptively adjusted based on the characteristics associated with the individual scenes.

There is provided with an information processing apparatus. A playlist generation unit generates a playlist including a URL (Uniform Resource Locator) for acquiring media data. A transmission unit transmits the media data and the playlist. The playlist includes at least one of transformation process information which indicates one or more transformation processes to be applied to the media data, and one or more layout information for spatially arranging the media data.
