Abstract

The present invention is a multiple-format multimedia interface module (100), comprising a first port (10), a circuit module (20), a first transmission line (30), a second port (40), and a second transmission line (50). The multiple-format multimedia interface module (100) connects a mobile device (60) with a display device (70) conveniently, and may bidirectionally transmit signals between a transmitter end with multiple signal formats of MHL, MyDP, and USB and a receiver end with a single signal format of HDMI or bidirectionally transmit signals between a transmitter end with a single signal format and a receiver end with multiple signal formats.

Description

technical field [0001] The invention relates to an audio-visual signal transmission device, in particular to a multi-standard audio-visual signal transmission device capable of connecting a mobile device with a display device. Background technique [0002] Due to the popularization of mobile devices in recent years, the demand for using mobile devices to watch or store multimedia audio-visual signals has also increased significantly. At present, the specifications of multimedia audio-visual signals used in mobile devices mainly include mobile high-definition link (MHL, Mobile High-Definition Link) and mobile display interface (MyDP, Mobility DisplayPort). Universal bus (micro-USB) interface. [0003] On the other hand, the development of liquid crystal display technology has also greatly reduced the price of display devices, and the demand for applications and ownership has also increased significantly. However, most of the multimedia audio-visual signal interfaces of the ...
