Abstract
A network device includes a communication interface and a processor. The communication interface may receive a multicast stream that includes a frame. The processor is coupled to the communication interface and may determine whether to send the frame unicast or multicast. The communication interface transmits the frame unicast or multicast based on the determination by the processor. The determination by the processor may be based on characteristics of the frame. If the characteristics of the frame include characteristics of a key frame such as an I-frame, the processor may determine to transmit the frame unicast. The determination may also be based on a predetermined state of client devices that are to receive the frame. If a client device is in a predetermined state such as a power save state, the processor may determine to transmit the frame unicast to that client device. Other embodiments are also described.
