Embodiment 1

[0078] Such as figure 1 As shown, the embodiment of the present invention provides an infrared remote controller, including: a pointing stick or an optical touch mouse 1 , a central processing unit 2 , a keyboard 3 and an infrared emitting circuit 4 .

[0079] The pointing stick or the optical touch mouse 1 is directly connected to the central processing unit 2, and the user controls the movement of the cursor through the pointing stick or the optical touch mouse 1, and the pointing stick or the optical touch mouse generates cursor movement data in real time. Such as figure 2 As shown, integrate the pointing stick on the infrared remote control, or integrate the optical touch mouse on the infrared remote control.

[0080] The keyboard 3 is connected with the central processing unit 2, such as figure 2 As shown, the keyboard 3 can be extended to 60-128 keys on the basis of the existing infrared remote control keyboard, including shift key, ctrl key, fn key, data keys 0-9, ...

Embodiment 2

[0100] Such as Figure 4 As shown, a method for sending data transmission provided by an embodiment of the present invention includes:

[0101] Step 101: The infrared remote controller samples the cursor movement data integrated in its own pointing stick or optical touch mouse every 54ms, and when the user moves the cursor, sends an Asf data frame to the receiving end to notify the receiving end to start moving the cursor;

[0102] Wherein, a pointing stick or an optical touch mouse is integrated in the infrared remote controller, and the user can control the movement of the cursor through the pointing stick or the optical touch mouse. When the user moves the cursor through the pointing stick or the optical touch mouse, the pointing stick or the optical touch mouse generates cursor movement data in real time, including the abscissa x and y coordinate of the current cursor.

[0103] In addition, the infrared remote controller temporarily stores the cursor movement data of the la...

Abstract

The invention discloses a data transmission method and an infrared remote controller, which belong to the field of wireless communication. The data transmission method comprises that: the infrared remote controller samples cursor moving data from a track point or an optical touch mouse integrated on the infrared remote controller with a period of 54 ms in real time, transmits a notice to a receiving end when a user starts to move a cursor, alternately combines the cursor moving data into a B cursor moving data frame and an A cursor moving data frame with the period of 108 ms and transmits thedata frames to the receiving end; when pressing a composite key down, the user combines key codes of the composite key into a key command frame and transmits the key command frame to the receiving end; when pressing a one-click key down, the user combines the key codes of the one-clock key into a single-key one-click frame and transmits the single-key one-click frame to the receiving end; and when pressing a double-click key down, the user combines the key codes of the double-click key into a single-key double-clock frame and transmits the single-key double-click frame to the receiving end. The data transmission method can enable the infrared remote controller to perform cursor input in an electrical appliance under the remote control of the infrared remote controller.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data transmission method and an infrared remote controller. Background technique [0002] Infrared remote control is a remote control device, which can remotely control various electrical appliances, which is convenient for people's life. [0003] For example, with an infrared remote controller used to remotely control a television, the user can directly use the number keys on the infrared remote controller to change channels, and use the keyboard for volume adjustment to adjust the volume of the television. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Current infrared remote controllers cannot input cursors into the electrical appliances they control. For example, an infrared remote control used to control a TV cannot input cursors in the TV. Contents of the inv...
