Problems solved by technology

[0013] However, in the above Patent Document 1, for example, if the unallocated bandwidth of the relay device 1710b is only 10 Mbps, the minimum requested bandwidth requested by the content transmitting terminal 1700 is not satisfied, so the content receiving terminal 1720 cannot receive desired content.

Embodiment approach 1

[0113]

[0114] figure 1 It is a system diagram showing the system configuration of the band setting system. As shown in the figure, the frequency band setting system includes a wireless slave unit 100, PLC (Power Line Communication) devices 200a, 200b, 200c, and 200d, a content transmitting terminal 300, a content receiving terminal 310, and wireless master units 320b and 320c. , 320d to form. Such as figure 1 As shown, the content transmission terminal 300 is wired to the PLC device 200a. In addition, the PLC devices 200a, 200b, 200c, and 200d are connected to each other through a power line network, and QoS settings can be performed. As shown in the figure, the PLC device 200b and the wireless master machine 320b, the PLC device 200c and the wireless master machine 320c, and the PLC device 200d and the wireless master machine 320d are paired. In this figure, the wireless slave device 100 is wirelessly connected to the wireless master device 320 b and is paired with ...

Embodiment approach 2

[0216] In the above-mentioned embodiment, when the setting between the PLC devices fails, the PLC device itself proposes a new route to the wireless slave unit. Here, after that, that is, after the wireless slave unit switches the wireless master unit for frequency band setting, the content transmission terminal fails to perform the QoS setting between the PLC devices connected to the wireless master unit instead of the PLC device. Implementation of the following processing.

[0217]

[0218] Figure 8 It is a system diagram showing the system configuration of the frequency band setting system according to the second embodiment. As shown in the figure, the frequency band setting system includes a wireless slave unit 400, PLC devices 500a, 500b, 500c, and 500d, a content transmitting terminal 600, a content receiving terminal 610, and wireless master units 620b, 620c, and 620d. The basic structure It is the same as that shown in Embodiment 1. Hereinafter, parts that are di...

Embodiment approach 3

[0263] In Embodiments 1 and 2 above, a closed network is disclosed in which a content transmitting terminal and a content receiving terminal can always be connected to any wireless main unit with which the wireless slave unit is to be connected. However, in Embodiment 3, a case will be described in which a wireless master unit to which a wireless slave unit can be connected is not necessarily connectable to a content transmission terminal.

[0264]

[0265] exist Figure 13 The system configuration of this embodiment is shown in . As shown in the figure, the frequency band setting system includes a wireless slave unit 700, PLC devices 800a, 800b, 800c, and 800d, a content transmitting terminal 900, a content receiving terminal 910, and wireless master units 920b, 920c, and 920d. The basic structure It is the same as that described in Embodiment 1. Here, in addition to devices included in the frequency band setting system, as wireless masters to which the wireless slave 100...

Abstract

A wireless communication device capable of receiving a content by securing a band as much as possible, if a predetermined band is required to be secured when the content is received by wire. The wireless communication device judges whether or not the predetermined band necessary for receiving the content can be secured with a wireless master device. When it is judged that the predetermined band cannot be secured, the wireless communication device switches a connection destination from the wireless master device to which the wireless communication device has been connected to a different wireless master device that can secure the predetermined band, e.g., a predetermined receiving electric field strength.

Description

technical field [0001] The present invention relates to a wireless communication device, and particularly relates to a technique for securing a frequency band for content distribution. Background technique [0002] In wireless distribution of content such as streaming distribution, a predetermined frequency band may be reserved between a server distributing the content and a terminal receiving the content in order to smoothly reproduce content requiring real-time performance such as audio or video. The content is distributed from the server to the terminal via devices such as wireless or wired, and via routers. A technique for securing this frequency band is known as QoS (Quality of Service). [0003] The related technology is to reserve a frequency band specified by a server that distributes content between two devices that transmit and receive content, and between the devices that transmit and receive content before transmitting content, thereby ensuring a constant commun...
