Abstract

Transmitting from a wireless router a live stream of time stamped multimedia packets from a server which is capable of providing a system time clock value is disclosed. The wireless router includes a queue for storing the time stamped multimedia packets received from the live streaming server. The wireless router also includes a processor for analyzing the priority of the time stamped multimedia packets stored in the queue, for comparing the time stamps to the system time clock value, for calculating a transmission time to a video client, and for determining a transmission window to transmit the time stamped multimedia packets. The time stamped multimedia packets are discarded if the packets cannot be transmitted within the transmission window, or the time stamped packets are immediately transmitted if they can be transmitted within the transmission window. The priority of the packets in queue may be re-sorted prior to transmission.
