Abstract: A method for checking channel interference in short range communication is provided to stably transmit a stream and to obtain an effect of load balance in short range communication. A transceiver, monitoring frames, checks the number of frames successfully received to a receiver whenever a preset time lapses(S500,S501). The transceiver compares the number of successfully received frames with an upper limit value and a lower limit value(S502,S504). In case the number of successfully received frames is smaller than the upper limit value, the transceiver subtracts the difference value from an initial value(S503). And if the number of successfully received frames is larger than the lower limit value, the transceiver adds the difference value to the initial value(S505). Every time an appointed period elapses, the transceiver compares the varied number of frames with a threshold value whenever the preset time elapses, in a state that the initial value is continuously changed(S506,S507). If the varied number of frames is smaller than the threshold value, the transceiver judges that interference has occurred(S508).

Abstract translation: 提供一种用于在短距离通信中检查信道干扰的方法，以稳定地发送流并获得短距离通信中的负载均衡的效果。 收发器，监控帧，在预设时间过去时，检查成功接收到的接收机的帧数（S500，S501）。 收发器将成功接收的帧数与上限值和下限值进行比较（S502，S504）。 在成功接收帧数小于上限值的情况下，收发器从初始值中减去差值（S503）。 如果成功接收到的帧数大于下限值，则收发器将差值加到初始值（S505）。 每当指定时间段过去时，收发器在初始值连续变化的状态（S506，S507）中，每当经过预设时间时，将不同数量的帧与阈值进行比较。 如果不同帧数小于阈值，则收发器判断已经发生干扰（S508）。

Abstract: An A/V equipment and a channel selecting method are disclosed, wherein the A/V equipment forms a wireless network by using information of each channel obtained by scanning each channel of a monitoring channel set to compute a predetermined parameter, and comparing the computed parameters to select an optimum channel. Consequently, the A/V equipment is configured to form a wireless network at a channel in which the wireless environment is the most satisfactory, thereby being enabled to satisfy a QoS requirement and to provide good quality of service, and to effectively distribute frequency resources under an environment, where the wireless equipment is mixed exists
