A method of embedding vector graphics content such as SVG into the 3GPP ISO Base Media File Format for progressive downloading or streaming of live rich media content over MMS / PSS / MBMS services. The method of the present invention allows the file format to be used for the packaging of rich media content including graphics, video, text and images; enables streaming servers to generate RTP packets; and enables clients to realize, play, or render rich media content.

Provided are a method and apparatus for storing and playing back an MPEG-2 TS based on an ISO-based media file format. The method includes: storing a target MPEG- 2 TS in an mdat box of the ISO-basedmedia file format; and dividing the MPEG-2 TS by samples through time information, location information, size information, and Program Map Table (PMT) related information for random access and describing the divided samples in an moov box of the ISO-based media file format.

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.

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 includes configuring the DAM for delivery in an MPEG-2 Transport System (M2TS). The method also includes transmitting a DAM to the UE to control energy consumption of the presentation on a display of the UE.
