Wireless display

Abstract

This invention relates to a radio display device including a control module, a user control unit connected with the control module, a USB interface module, a LCD driver, an amplifying and D / A converting module, a display screen and an audio output device connected with the LCD driver, power amplifying and D / A converting module and a power supply or its interface, in which, the USB interface module receives the decoded audio and video data flows sent by peripheral equipments and converts them into a mode identified by the control module, a microcontroller distributes the audio and video data flows into the power amplifying and D / A converting module and the LCD driver, which converts the video data flow into the format suitable for the display of screens and the converting module converts the audio data flow into analog signals to be amplified and output to the audio output device to be played.

Description

【Technical field】 [0001] The present invention relates to a wireless display device, in particular to a device which uses a wireless USB to receive decoded audio and video data streams, and displays and plays them on a display screen and an audio output device after processing them. 【Background technique】 [0002] With the rapid development of digital technology, video entertainment devices are becoming cheaper and cheaper, and thus tend to become electronic equipment commonly owned by families. These video playback devices can play the video and audio data stored in themselves. [0003] see figure 1 Shown is a schematic diagram of a video playback device in the prior art. It mainly includes: a processing module, which controls the working status of each component in the video playback device, and handles data calculations. It includes a processor and a buffer memory and memory connected to the processor, and the processing module performs data processing and input and outp...

AI Technical Summary

Problems solved by technology

The defect of the above-mentioned patented technology is that the wireless multimedia communication terminal is set independently from the audio and video equipment and connected with a cable, so the wireless multimedia communication terminal needs to be connected to the audio and video equipment separately when in use. The function of audio and video playback and display cannot be realized. In addition, the wireless multimedia communication terminal is equipped with a decoder for locally decompressing the multimedia resource information obtained from the computer, and it needs to be equipped with a corresponding processor with a large amount of data processing, thus increasing manufacturing cost
