System and method embodiments are provided for asynchronous event notification and message handling in dynamic adaptive streaming over hypertext transfer protocol (DASH). The embodiments includes sending in a segment file, from a network server to a client, a message box that is configurable for encryption, for scheduling a callback from the client, and with one or more arguments according to a messaging scheme of the message box. The network server further sends a message handling descriptor to the client for reloading a media presentation description (MPD) for obtaining a DASH event. The client then configures a universal resource locator (URL) for the MPD using the message box and the message handling descriptor, and sends the URL back to the network server. After receiving the URL, the network server sends the MPD to the client, which then uses the MPD to request segments of an asynchronous event.

Disclosed are methods and devices for providing metadata (120) to be stored. Periods may be indicated by a point at which the metadata becomes valid (150) and a second point at which the metadata becomes invalid (160). The metadata may be encoded, by an encoder (500) in a file format compatible with or based upon an ISO Base Media File format (510). Similarly, the indication of the point at which the metadata becomes valid and the indication of the second point at which the metadata becomes invalid may also be encoded in the file format compatible with or based upon the ISO Base Media File format. This may be performed by a transmitter (400) or by a receiver (470). A plurality of metadata items may also be stored in the file format in a single location providing efficient storage and retrieval.

A video processing method includes receiving a virtual reality (VR) content, encoding visual data obtained from the VR content to generate a part of a coded bitstream, and encapsulating the part of the coded bitstream into ISO Base Media File Format (ISOBMFF) file (s). In one exemplary implementation, the ISOBMFF file (s) may include a timed metadata track associated with a sphere visual track, where the timed metadata track is set to signal that the associated sphere visual track contains at least one spherical region contributed from at least one region visual track. In another exemplary implementation, the ISOBMFF file (s) may include a timed metadata track associated with a region visual track, where the timed metadata track is set to signal that the associated region visual track contributes to at least one spherical region carried in at least one sphere visual track. Further, an associated video processing apparatus is provided.

A metabox container box which is capable of storing multiple meta boxes for use. The metabox container box can also include a box which indicates the relationship between each of the meta boxes stored in the metabox container box. Various embodiments of the present invention are also backward-compatible with earlier versions of the ISO base media file format.

A method for providing display adaptation metadata (DAM) to a user equipment (UE) at a system level is provided. The method includes configuring the DAM for storage in the International Organization for Standardization (ISO) Base Media File Format (ISOBMFF). The method also includes transmitting a DAM to the UE to control energy consumption of the presentation on a display of the UE. A method for providing display adaptation metadata (DAM) to a user equipment (UE) at a system level is provided.

The method to signal DRM information in an AVS-M file is disclosed in the present invention. Following the general ISO base media file format box structure to achieve the interoperability and compatibility, the default encryption algorithm and related key management information in an IPMP descriptor is defined and carried in a required protection scheme box. The general IPMP signaling scheme through an IPIP tool ID declared by the IPMP descriptor as well is provided to achieve the flexibility in case the default protection scheme is broken or multiple DRM modules are desirable to protect such one video data. Rights data information to facilitate getting the actual usage rule for the content is also provided. The original content type of the media is kept in the new protected media form. Such file is useful to interchange, edit and playback for AVS-M video, especially for its IP protection.

Systems and methods for storing notification messages in an ISO base media file are provided, where different transport cases when notification messages are to be stored are addressed. The systems and methods enable the linking of notification message parts delivered over RTP with other parts of a notification message carried over file delivery over unidirectional transport (FLUTE) or some other protocol.
