ISO SYSTEM AND METHOD FOR SECURE ASYNCHRONOUS EVENT NOTIFICATION FOR ADAPTIVE STREAMING BASED ON ISO BASE MEDIA FILE FORMAT

摘要

hypertext transfer protocol via the dynamic adaptive streaming (dynamic adaptive streaming over hypertext transfer protocol, DASH) in the asynchronous event notifications and message processing system and method for an embodiment to be provided. The embodiment to a client from a network server, and includes transmitting a message box to the segment file, the message box is encrypted, the possible configuration for the callback scheduling from the client, and one or more in accordance with the messaging system of the message box, It has an argument (argument). The network server also sends media expression technology (media presentation description, MPD) the message to the client processing descriptor (descriptor message handling) for re-loading to obtain the DASH event. Then, the client constitutes a universal resource locator (universal resource locator, URL) for the MPD using the message box and the message processing descriptor, and sends the URL back to the network server. After receiving the URL, the network server will request a segment of an asynchronous event using transmit the MPD to the client, and then the MPD. ;
