System and method for secure asynchronous event notifications for adaptive streaming based on Iso base media file format

摘要

Aspects of the systems and methods are provided for the asynchronous event notifications and message handling in a dynamic adaptation streaming over Hypertext Transfer Protocol (DASH). Aspect, from a network server to a client, comprising the steps of sending a message box, the segment file, message box, may be configured for encryption, to schedule a call-back from the user device, and the message having one or two or more arguments based on the messaging scheme of the box, including the step of transmitting. Network server further, in order to reload a media presentation description (MPD) for obtaining DASH event, the message handling descriptor, to send to the client. The client then uses the message boxes and message handling descriptor constitutes a universal resource locator (URL) to the MPD, and returns the URL to the network server. After receiving the URL, the network server sends the MPD to the client, then uses the MPD to request a segment of asynchronous events.
