Audio control device and method

Abstract

The invention relates to an audio control device and method. The audio control device comprises a data communication module, a central processing unit, a speech synthesis chip and a memory module, wherein the central processing unit is electrically connected with the data communication module, the speech synthesis chip and the memory module; the data communication module is used for acquiring a program file; the program file comprises text data corresponding to the program text content; the central processing unit is used for caching the program file in the memory module, processing the text data according to preset display control parameters to enable the program text content to be displayed on an LED screen according to the display control parameters, and sending the text data to the speech synthesis chip meanwhile; the speech synthesis chip is used for synthesizing the text data into a voice message, and synchronously playing the voice message when the program text content is displayed according to the display control parameters. The audio control device and method can realize image-text real-time synchronous playing in a sound and text manner.

Description

technical field [0001] The present invention relates to the field of media playing, in particular to an audio control device and method. Background technique [0002] With the rapid development of light-emitting diode (Lighting Emitting Diode, LED) display screens, advertisers or other users no longer meet the requirements of single-screen LED display screens, and the demand for multimedia is also increasing. How to integrate audio and subtitles to provide better advertising services is an urgent problem to be solved. [0003] In the prior art, audio control methods based on LED display mainly include the following two types: [0004] The first method is to send images and sounds in real time through the computer, and its principle block diagram can be shown as figure 1 shown. [0005] figure 1 The middle LED screen display screen 101 connects the sound player 104, and adds a sound control integrated circuit (not shown in the figure), the content to be played is sent to ...

AI Technical Summary

Problems solved by technology

[0009] 1. Since the received information is not processed, the co-playing of video and audio is realized by separating the text information from the audio information and playing them separately, which can easily cause the video and audio to be out of sync;

[0010] 2. Due to the need for real-time computer participation, offline playback cannot be realized

[0012] 1. The system structure is complex and the hardware cost is too high;

[0013] 2. The sound information is directly input from the outside and cannot be synchronized in real time
