Methods and systems are provided for transmitting multiple video streams to clients based on individual preferences of the clients and network conditions. A cost-function minimization problem is formulated based on various network parameters. The network parameters (e.g., round-trip time (RTT), available bandwidth, packet loss rate, etc.) may be inputs to this optimization problem, which attempts to find optimal resolutions, bitrates, etc., given the network parameters and the video content. Additionally, by incorporating quality prediction, the cost-function may be based on actual content of video sequences. |
