Embodiment Construction

[0043]The device control method provided by this application is applied to a multimedia device. For a schematic diagram of the connection between the multimedia device and a mobile terminal, please refer to figure 2 As shown, the controller of the multimedia device is connected to the signal conversion module of the multimedia device through an interface, and the controller is used to generate an Operate the corresponding control signal. The control signal is used as a touch control signal.

[0044] exist figure 2 In the connection diagram shown, the controller and the signal conversion module are connected through the RS232 interface. Of course, other interfaces can also be used to connect the two, such as IIC (Inter-Integrated Circuit, integrated circuit bus) interface or SPI (Serial Peripheral Interface, serial peripheral interface), when the controller and the signal conversion module are connected by different interfaces, the controller converts the generated touch co...

Abstract

The present application provides a device control method, device, and multimedia device, wherein the controller is connected to the signal conversion module through an interface. When the user operates the operation interface of the mobile terminal displayed on the multimedia device, the controller generates a signal corresponding to the operation. touch control signal. And the signal conversion module is connected with the mobile terminal through the MHL interface. When it receives the touch control signal, it encapsulates the touch control signal according to the RCP specification of the MHL protocol, and sends the encapsulated touch control signal through the CBus pin of the MHL interface, and the mobile terminal parses and responds to the signal sent by the CBus pin, thereby Realize mutual control between multimedia equipment and mobile terminal. Further, the CBus pin of the MHL interface is used to send signals between the multimedia device and the mobile terminal, and the CBus pin connection belongs to the signal line connection, which improves the anti-interference ability of the touch control signal during transmission, thereby improving transmission reliability.

Description

technical field [0001] The present application relates to the technical field of multimedia equipment, in particular to a device control method, device and multimedia equipment. Background technique [0002] The MHL (Mobile High-Definition Link, high-definition audio and video standard for mobile terminals) interface is widely used in mobile multimedia devices using the Android operating system, and the mobile multimedia device sends the MHL signal to other multimedia display devices through the MHL interface, and is displayed by other multimedia devices. The device plays the multimedia information carried by the MHL signal. The mobile terminal and the vehicle-mounted multimedia device are taken as examples for description below. [0003] The schematic diagram of the connection between the mobile terminal and the vehicle-mounted multimedia equipment is as follows: figure 1 As shown, the mobile terminal sends the MHL signal to the signal conversion module of the vehicle mul...
