[0036] According to the first embodiment of the present invention, an image display device compatible with the QoS function under discussion of "IEEE802.11e / D8.0 February 2004" and having a wireless LAN access point function is exemplified. The wireless LAN according to the first embodiment is obtained by adding the QoS function under discussion of the IEEE802.11e draft of "IEEE802.11e / D 8.0 February 2004" to the IEEE802.11g 2.4GHz band wireless LAN scheme. Contrary to this QoS wireless terminal, a conventional wireless LAN terminal incompatible with "IEEE802.11e / D8.0February 2004" is called a non-QoS wireless terminal.
[0037] figure 1 is a block diagram showing the configuration of the image display device 100 with an access point function according to the first embodiment.
[0038] exist figure 1, reference numeral 101 denotes a QoS compatible access point (QAP) (hereinafter referred to as access point 101 ) according to the first embodiment. Reference numeral 102 denot...

[0139] In the first embodiment, the third threshold γ is a fixed value. However, the third threshold γ may be variable according to factors such as the number of connected terminals. In the second embodiment, the third threshold γ is variable.
[0140] Figure 12 is a flow chart showing an example of the second embodiment and the updating process of the first, second and third thresholds α, β, γ when the third threshold γ is a variable. In the second embodiment, with Figure 8 The processing shown is the same, and the update flow of the first, second, and third thresholds α, β, and γ is also updated in each beacon period.
[0141] exist Figure 12 Among them, step S21 is the same as step S1, and steps S31 to S36 are the same as steps S2 to S7, so the description thereof will be omitted. When the first and second thresholds α and β are updated in steps S35 and S36 after the process starts or after the end of the beacon period, the collision number parameter "m" is initiali...

[0157] In the first embodiment, the priority in the information table is determined by mode, AC, and average data rate. However, priority can be determined by using parameters such as average data rate or peak data rate obtained from TSPEC. Priority can also be determined based on the remaining information in the TSPEC.
[0158] Also, in the first wireless terminal device 201 or the second wireless terminal device 202 having a plurality of wireless channels, the aperiodic data transmission channel may be connected before the video channel and the audio data transmission channel are connected. The application program of the access point 101 may receive the same terminal control information as the TSPEC information element from the application program of the second wireless terminal device 202 through the aperiodic data transmission channel.
[0159] In the first embodiment, the AP manager 301, within a period predetermined by an internal timer, at Figure 9In the flow shown, ...
