Abstract: 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.

Abstract: Embodiments are provided herein for a system and methods for real-time video (or other real-time traffic) delivery, e.g., for cellular or wireless networks. The schemes herein address real-time video delivery by a joint design of the radio resource scheduler and the video encoder at the network side, and of the decoder at the users' terminals. The system design reduces frame loss and hence improves user quality of experience. In an embodiment, a radio node detects a frame of a real-time traffic flow. Upon determining that a transmission deadline corresponding to a rate for real-time traffic flow does not support a size of the frame, the transmission deadline is extended according to the size of the frame and a size of a next frame. The frame and the next frame are scheduled for forwarding within the extended transmission deadline.
