  • Method and apparatus for changing communication link between source devices and sink devices
    Patent number: 8340035
    Abstract: Provided is a method of changing a communication link between source devices and sink devices. The method includes in a first downlink period, broadcasting an uplink period allocation message to the sink devices and passive source devices by an active source device, which establishes a communication link with a primary sink device from among the sink devices; during a first uplink period, broadcasting by a primary passive source device a link set message for establishing a communication link with the primary sink device to all the source devices in the network; during a second downlink period, relaying the link set message to all the sink devices in the network, wherein the link set message is relayed by the active source device; and during a second uplink period, establishing a communication link between the primary sink device and the primary passive source device by the primary sink device.
