COMMUNICATION CONTROL APPARATUS AND CONTROL METHOD THEREOF, COMMUNICATION APPARATUS AND CONTROL METHOD THEREOF, WIRELESS COMMUNICATION SYSTEM, AND STORAGE MEDIUM

摘要

A communication control apparatus, a control method thereof, a communication apparatus, a control method thereof, a wireless communication system and a recording medium are provided to prevent abnormality, occurring in single communication connection, through the other communication connection by enabling plural communication devices to transmit the same data iteratively within the same interval, and transmit data to all communication devices within the same interval, thereby preventing interference of transmission according as all terminals are temporally synchronized. A control terminal comprises a wireless transmitter(201), a wireless receiver(202), a controller(203), an encoder(204), a memory(205), an interval timer(206) and an antenna(207). The controller transmits control data to the wireless transmitter through the memory. The controller modulates the control data into a wireless signal by controlling the wireless transmitter, and wirelessly transmits the modulation result to the antenna. The encoder converts AV(Audio/Video) data from a data source into stream data. The memory temporarily stores the converted stream data. The control terminal converts the stream data into a frame as a unit of transmission data by being synchronized with the interval timer according to an instruction from the controller, and transmits the conversion result from the memory to the wireless transmitter. The wireless transmitter modulates the data from the memory into a wireless signal by being synchronized with the interval timer according to an instruction of the controller, and wirelessly transmits the modulation result from the antenna. The wireless receiver receives the wireless signal from the antenna, demodulates the wireless signal into received data, and transmits the received data to the controller. A grouping unit groups plural communication devices based on each relative location of each communication device. A notification unit notifies a group to which the communication device belongs and a communication slot assigned to the group with respect to each of plural communication devices. A transmission unit transmits transmission data at predetermined timing.
