Abstract:
A method of transmitting a live video stream and a pre-recorded video stream over a wireless network to a mobile device, the method including: receiving the live video stream and the pre-recorded video stream for a current scheduling window; dividing the live video stream and the pre-recorded video stream into segments in the current scheduling window, each segment including an aggregate data amount, a transmission start time and a transmission end time; determining a transmission schedule for the current scheduling window, said transmission schedule including the segments; locating slack time slots, the slack time slots being time slots for which no segment is allocated; and scheduling bursts associated with the pre-recorded video stream in the slack time slots.
