Multifunctional communication interface and method for realizing multifunctional communication of interface

Abstract

The invention provides a multifunctional communication interface which comprises a 2.4G wireless transceiver and a control unit. The control unit comprises a match code recognition module, a channel selection module, a signal conversion module used for converting a RF (Radio Frequency) signal into an infrared signal and generating a PWM (Pulse Width Modulation) signal and a communication module. The 2.4G wireless transceiver is connected with the match code recognition module of the control unit; the match code recognition module is connected with the channel selection module; the signal conversion module receives information sent by the channel selection module and sends the information to a smart TV motherboard; a TCON sends a signal to the signal conversion module; and the signal conversion module outputs the signal to a backlight drive module. Through communication between the multifunctional communication interface and a TV main chip, communication between a smart remote controller, a touch and talk pen as well as a pair of 3D glasses and the TV is realized through one communication interface, and the problem of separate communication of multiple communication modules is solved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multifunctional communication interface. Background technique [0002] In recent years, with the rapid development of computer and Internet technology, TV is a multi-functional terminal, and users expect to get more information and services. There are also more and more modules, and smart TVs with smart remote control, point-and-click and 3D images have appeared, which requires smart TVs to add different peripheral functions and communication interfaces. [0003] However, when traditional smart TVs add different peripheral function modules, they generally use separate modules for communication and connect with serial ports or USB ports. Although this method can shorten the development time in the early stage, it has multiple The module will increase the cost of the whole machine, and the placement of the structure must also be considered. Especially when the number of int...

[0003] However, when traditional smart TVs add different peripheral function modules, they generally use separate modules for communication and connect with serial ports or USB ports. Although this method can shorten the development time in the early stage, it has multiple The module will increase the cost of the whole machine, and the placement of the structure must also be considered, especially when the number of internal reserved interfaces (such as serial ports, USB interfaces) is not enough, it is more troublesome to add expansion interface chips
