Benefits of technology

The present invention provides a method and apparatus for managing multiple channels in a multi-channel input system, which can prevent interference and quickly and accurately set channels. The invention also includes a multi-channel interference management method and a multi-channel terminal that can detect interference and select an alternative channel to avoid interference. The invention can efficiently manage channel settings and provide a better user experience for cordless connections between terminals and input apparatuses.

Problems solved by technology

Therefore, users cannot easily understand channels that have been set at other terminals and radio keyboards.
In this case, there has been a problem that the terminal 101 can receive key data from both the radio keyboard 201 and the radio keyboard 202, and this results in the occurrence of interference.
Further, there has been a problem that even if the set channel of the terminal 101 and the radio keyboard 201 has been changed from the channel CH1 to the channel CH2, the terminal 101 can receive the key data from both the radio keyboard 201 and the radio keyboard 202, and this results in the occurrence of interference.
As a result, there has been a problem that it takes time to set the channels, and errors easily occur in the channel setting.

first embodiment

[0065]FIG. 1 is a block diagram showing a structure of the present invention. FIG. 1 shows a multi-channel input system that has a plurality of terminals connected to a plurality of radio keyboards corresponding to these terminals via radio links based on a multi-channel system, for enabling a high-order terminal to manage the setting of the plurality of channels, and catch the interference status of the channels.

[0066] Specifically, the multi-channel input system is constructed of a high-order terminal 100 for managing the setting of channels CH1 to CHn (refer to FIG. 2) and catching a channel interference status, n terminals 3001 to 300n that are connected to the high-order terminal 100 via a network 200, displays 4001 to 400n that are connected to these terminals 3001 to 300n respectively, and n radio keyboards 5001 to 500n corresponding to the terminals 3001 to 300n respectively. In this multi-channel input system, key data are transmitted and received in the units of terminals ...

second embodiment

[0162]FIG. 13 is a block diagram showing a structure of the present invention. In this drawing, portions corresponding to those shown in FIG. 1 are attached with like reference numbers. In FIG. 13, a multi-channel input system is constructed of a high-order terminal 700 for managing the setting of channels CH1 to CHn (refer to FIG. 2) and catching a channel interference status, n terminals 8001 to 800n that are connected to the high-order terminal 700 via a network 200, displays 4001 to 400n that are connected to these terminals 8001 to 800n respectively, and n radio keyboards 9001 to 900n corresponding to the terminals 8001 to 800n respectively.

[0163] The high-order terminal 700 is a personal computer for managing the setting of the channels CH1 to CHn and catching a channel interference status. The high-order terminal 700 can communicate with the terminals 8001 to 800n via the network 200. In this high-order terminal 700, a CPU 701 executes the management of the setting of the cha...

Abstract

A multi-channel input system connects between a plurality of terminals and a plurality of radio keyboards corresponding to these terminals by radio links (channels), according to a multi-channel system. A high-order terminal has a CPU that manages a setting status of each channel in this multi-channel input system, by using a channel-setting table, and notifies the setting status to any one of the terminals a according to a request from this terminal.

Description
