Abstract

The application relates to a signal conversion module and a mobile terminal, wherein the signal conversion module comprises a signal conversion chip and a high-definition multimedia interface, and thesignal conversion chip is connected to the high-definition multimedia interface; when an external device is connected to the high-definition multimedia interface, the signal conversion chip receivesaudio and video signals of the high-definition multimedia interface transmitted by the external device, converts the audio and video signals of the high-definition multimedia interface into audio andvideo signals of a mobile industry processor interface, and transmits the audio and video signals of the mobile industry processor interface to an external mobile terminal main control chip, and the external mobile terminal main control chip generates audio and video data according to the audio and video signals of the mobile industry processor interface. The mobile terminal includes a main control chip and a signal conversion module. The signal conversion module or the mobile terminal may effectively improve the transmission rate of the audio and video signals of the high definition multimedia interface.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a signal conversion module and a mobile terminal. Background technique [0002] With the development of science and technology, various smart devices emerge in an endless stream, such as smart phones and tablet computers, which have greatly changed people's production and lifestyle. People can realize data transmission and sharing through smart phones, tablet computers and other devices. [0003] Smartphones, tablet computers, etc. mostly use USB (Universal Serial Bus, Universal Serial Bus) interface, Mini USB interface and other wireless interfaces to transmit data with external devices based on MIPI (Mobile Industry Processor Interface, Mobile Industry Processor Interface). MIPI is an open standard and a specification for mobile application processors initiated by the MIPI Alliance. The traditional data transmission method has the problem of low transmission rate when tra...
