Abstract: Methods and apparatuses for managing received data by a client device and indicating data removal management by a server. A method for managing received data by a client device includes receiving a message including information about a number of modes for removal of the data from a buffer at the client. The method also includes selecting a mode for removal of the data from the buffer with a maximum required buffer size among the modes indicated by the information about the modes in the received message and removing the data from the buffer based on the identified mode. A method for indicating data removal management by a server includes generating and sending a message including information about a number of modes for removal of received data from a buffer at a client device. The information indicates, for each of the modes, a type of mode for removal of the data.

Abstract: A method, an electronic device, and computer readable medium is provided. The method includes receiving, from a media source, a request for media processing, where the request includes a requested media output. The method also includes identifying one or more media processing functions to perform the request for media processing based on information associated with each of the one or more media processing functions. The method further includes configuring each of the one or more media processing functions by mapping the request for media processing to the one or more media processing functions based on the information associated with each of the one or more media processing functions. The method additionally includes monitoring the one or more media processing functions while the one or more media processing functions perform tasks to generate the requested media output.

Abstract: An electronic device, a server and a method for rendering timed text within an omnidirectional video are disclosed. The method includes receiving a signaling message including a flag indicating whether a position of the timed text within the omnidirectional video is dependent on a viewport of the omnidirectional video. The method also includes determining whether the position of the timed text within the omnidirectional video is dependent on the viewport based on the flag. The method further includes rendering the timed text within the omnidirectional video based on the determination.
