System and Method for Secure Asynchronous Event Notification for Adaptive Streaming Based on ISO Base Media File Format
ActiveUS20130268761A1User identity/authority verificationSelective content distributionMessage handlingUniform resource locator
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 file transfer method and a terminal adapted thereto are disclosed. When a moving image file request signal is revived, a determination is made as to whether the moving image file to be transferred is in an ISO base media file format. If the moving image file to be transferred is in an ISO base media file format, a movie (moov) box is rearranged so that it is in front of a media data (mdat) box in the moving image file, in terms of the transfer sequence. The moov box is one of the boxes contained in the moving image file and contains detailed information to reproduce moving image data. After that, the moving image file composed of the rearranged boxes is transferred.
