摘要： Disclosed is a multicast controlling apparatus and method in a multi hop network. The multicast controlling apparatus in the multi hop network includes a packet determining unit to receive a packet from a group management query device or a station, and to determine whether the received packet is a group management protocol packet, a packet type distinguishing unit to distinguish a type of the received packet when the received packet is determined as the group management protocol packet, and a packet transmitting unit to transmit the packet to a second port excluding a first port that receives the query message, when the received packet is determined as the query message.

摘要： Provided is a technology of controlling an electronic device using a broadcasting system. A control signal may be modulated to an audible frequency band and thereby be transmitted from a transmission apparatus to a reception apparatus using the broadcasting system. The reception apparatus may reproduce the control signal of the audible frequency band. A controller may perform a control operation based on the control signal.
