Then, the multimedia playing device 100 may screen out a corresponding working channel from the obtained WiFi hotspot information, that is, as shown in table 1, the multimedia playing device 100 may obtain the working channel 13, the working channel 11, the working channel 6, and the working channel 149, and then perform secondary screening from the screened working channels based on the local frequency band, for example, 2.4Ghz, to obtain a screened channel having the same frequency band 2.4Ghz, and as can be known from the channel and frequency band standards, the working channel 149 corresponds to a channel having a frequency band 5Ghz, and is therefore excluded, and the rest is reserved, that is, a plurality of screened channels 6, 11, and 13 are obtained. The initial channel corresponding to the multimedia playing apparatus 100 is, for example, channel 7, and then the multimedia playing apparatus 100 determines the target channel based on the filtered channels, the initial channel and the available channels.
There are two ways of determining the target channel based on the multiple filtered channels, the initial channel, and the multiple available channels, where the first way is that the multimedia playing device 100 sequentially determines whether there is an available channel different from the multiple filtered channels in the multiple available channels, if there is an available channel, the determination is stopped, and the available channel different from the multiple filtered channels is used as the predetermined channel, if there is no available channel, the predetermined channel is determined based on the multiple filtered channels, and then it is determined whether the predetermined channel is the same as the initial channel, so as to obtain the target channel, for example, the preconfigured multiple available channels of the multimedia playing device 100 include: based on the foregoing examples of the initial channel and the filtered channels, the multimedia playback device 100 has an available channel 10 different from all of the filtered channels, and it can be understood that the available channel 10 does not have a corresponding WiFi hotspot, the available channel 10 is taken as a predetermined channel, and then it is determined that the predetermined channel, that is, the available channel 10 is different from the initial channel 7, and the available channel 10 is a target channel, and for example, the preconfigured multiple available channels of the multimedia playback device 100 include: the channel 6, the channel 11, and the channel 13, and if it is found after the judgment that the available channels of the multimedia playing device 100 are all the same as one of the plurality of screened channels, the screened channels are counted to obtain screened channels with few corresponding WiFi hotspots, that is, as can be seen from table 1, the working channel 11 corresponds to two WiFi hotspots, the working channel 13 corresponds to two WiFi hotspots and the working channel 6 corresponds to one WiFi hotspot, then the screened channel with the fewest corresponding WiFi hotspots, that is, the working channel 6, is used as a predetermined channel, it is judged whether the predetermined channel, that is, the working channel 6, is the same as the initial channel 7, at this time, the judgment is different, and the working channel 6 is used as a target channel.
In addition, the second way of determining the target channel based on the multiple filtered channels, the initial channel, and the multiple available channels is to determine whether there is an available channel different from the multiple filtered channels in the multiple available channels one by one for the multimedia playing device 100, after all the multiple available channels are determined, if it is determined that there is at least one first available channel, for example, the multiple first available channels are different from the multiple filtered channels, determine whether there is a channel identical to the initial channel in the multiple first available channels, if so, take the initial channel as the target channel, if not, randomly select one of the multiple first available channels as the target channel, if it is determined that each available channel is identical to one of the multiple filtered channels, determine the predetermined channel based on the multiple filtered channels, and then determine whether the predetermined channel is identical to the initial channel, thereby obtaining the target channel, for example, the plurality of available channels of the pre-configured multimedia playing device 100 includes: the available channels 6, the available channels 8, the available channels 10, the available channels 11, and the available channels 13, after determining the available channels, the available channels 8 and the available channels 10 are found to be different from the screened channels, further, when determining that the available channels 8 and the available channels 10 are both different from the initial channel 7, one of the available channels 8 and the available channels 10 is randomly selected as a target channel, and for example, the preconfigured available channels of the multimedia playback device 100 include: the channel 6, the channel 11, and the channel 13, and if it is found after the judgment that the available channels of the multimedia playing device 100 are all the same as one of the plurality of screened channels, the screened channels are counted to obtain screened channels with fewer WiFi hotspots, that is, as can be seen from table 1, the working channel 11 corresponds to two WiFi hotspots, the working channel 13 corresponds to two WiFi hotspots and the working channel 6 corresponds to one WiFi hotspot, then the screened channel with the least WiFi hotspot, that is, the working channel 6, is used as a predetermined channel, it is judged whether the predetermined channel, that is, the working channel 6, is the same as the initial channel 7, at this time, the judgment is different, and the working channel 6 is used as a target channel.
In short, the first and second manners of determining the target channel disclosed above are different in that the first manner of determining the target channel is to sequentially determine a plurality of available channels, and stop determining to perform the next step after determining that any one of the available channels is different from all of the plurality of screened channels, and the second manner of determining the target channel is to sequentially determine a plurality of available channels, and perform the next step after all of the plurality of available channels are determined.
After the target channel is obtained through the foregoing steps, the multimedia playing device 100 automatically configures the local WiFi hotspot to the target channel for operation. The client can then connect to the native WiFi hotspot to perform the aforementioned data transmission and control of the multimedia playback device.
