Abstract: In one embodiment, a mobile communications system has a plurality of radio access network (RAN) nodes communicating wirelessly with a plurality of wireless user devices, a video server transmitting one or more packetized video streams to one or more of the wireless user devices, and a packet core routing packets of video data from the video server to the one or more wireless user devices via the RAN nodes. For each packetized video stream, the video server transmits in-band information related to the packetized video stream, such as relative screen size, relative video activity level, and minimum and maximum video quality levels, and each RAN node extracts and uses the in-band information to schedule transmission of the packets of video data to its one or more corresponding wireless user devices. The system can provide higher-quality video experience without wasting bandwidth on user devices that don't require much communication resources.
