The present invention relates to a queue management unit and method for streaming video packets in a wireless network. The method includes determining a type of frame from a header of a video packet received at a transmit buffer. The method further includes discarding the received frame if the received frame is dependent upon any previously discarded frame, otherwise storing the received frame in one of a plurality of sub-queues of the transmit buffer according to the type of frame, where each sub-queue of the plurality of sub-queues stores frames corresponding to one type of frame. Also, the method includes creating space in the transmit buffer if there is insufficient space for a higher priority frame by discarding lower priority frames, as well as discarding frames in the transmit if the received frame is delayed more than a maximum period of time.
