Abstract

The invention discloses a method for realizing synchronous display of text, audio and video on a mobile communication terminal. In order to solve the problem that existing mobile communication terminals cannot display text files synchronously when playing audio or video files, the present invention proposes the following method: create a mark for each text file, and the mark includes the corresponding audio or video file and time mark; this method The method includes the following steps: 1. The mobile terminal receives a request from the user to play video or audio files; 2. The mobile terminal reads all text files corresponding to the audio or video files to be broadcast by retrieving the marks of the text files; 3. According to the time mark, determine the time when all text files start to play, start to play the audio or video file to be played, and start to play the text file when the time when the text file starts to play. The method of the invention can synchronously display text files along with audio or video files, and enhances the functions of existing mobile communication terminals.

Description

Method for Realizing Synchronous Display of Text and Audio or Video on Mobile Communication Terminal

technical field

The invention relates to a data processing method, in particular to a method for synchronously displaying text and audio or video on a mobile communication terminal.

Background technique

As a convenient tool for people to communicate, mobile communication terminal equipment has become an indispensable necessity in daily life. Especially since the 1990s, mobile communication terminal equipment has made great progress, and the call quality has been continuously improved. At the same time, people are no longer satisfied with using mobile communication terminal equipment only for calls, and have continuously developed various technologies that can be applied to mobile communication terminal equipment, which greatly meet people's needs for mobile communication terminal equipment. Communication terminal equipment can not only receive/send various voice signals, but also have the functions of image and text transmission and playback, and the function of receiving, sending and playing synchronous audio and video signals, such as the existing support for receiving and playing TV, mobile phone that supports video calling. However, the text cannot be displayed synchronously.

Contents of the invention

The purpose of the present invention is to address the defects in the prior art and propose a method that enables the mobile playback terminal to simultaneously play text display when playing audio and video signals.

The present invention is achieved in the following way: a method for synchronously displaying text and audio or video on a mobile communication terminal. First, a mark is established for each text file, and the mark includes: an audio or video file corresponding to the text file , a time mark, the mark indicates that the text file and the audio or video file establish a corresponding relationship;

The method includes the following steps:

(1) When the mobile terminal receives a request from the user to play a video or audio file, it reads all text files corresponding to the audio or video files to be played according to the mark of the text file corresponding to the video or audio file;

(2) Determine the time when all text files start playing according to the time stamps of all text files, start to play the audio or video files to be played, and play the text files when the playback time of the text files starts.

Wherein, the time mark is a time offset, that is, the difference between the time when the text file starts to play and the time when the corresponding audio or video file starts to play.

Wherein, a corresponding list is established for each audio or video file, and all text file tags corresponding to the audio or video file are stored in the corresponding list, and are arranged in sequence according to the time marks in the marks.

Wherein, the step (2) is specifically:

(A) judge whether the corresponding list of the audio or video file to be played is empty, if it is empty then start playing the audio or video file, the step ends; if not empty, then enter step (B);

(B) A timer is set, and the counter value of the timer is set to 0. When starting to play audio or video files, the timer records the playing time:

(C) read the time of starting playing of the first text file in the corresponding list, compare with the count value of the timer, when the count value of the timer is equal to the time mark, start to play the first text file , and delete the identifier of the text file from the corresponding list;

(D) Judging whether the corresponding list is empty, if it is empty, the step ends, if not empty, return to step (C).

Wherein, the step (1) also includes: judging whether the user has selected a text file synchronously played with the audio or video file, if selected, storing the text file selected by the user into the audio or video file In the corresponding list; if not selected, then in the text file list, retrieve all text files corresponding to the audio or video files to be played, and store the retrieved text files into the corresponding list of the audio or video files middle.

The present invention realizes synchronous display of text, audio and video on a mobile communication terminal, can synchronously display text files and audio or video files, enhances the functions of existing mobile communication terminals, and improves the usability of mobile communication terminals.

Description of drawings

Fig. 1 is a flowchart of a preferred embodiment of the present invention.

Detailed ways

The present invention will be further described below according to accompanying drawing.

To realize the synchronous display of text along with sound or video, it is necessary to provide a file containing the text to be displayed, which is divided into several basic sections, and each section is a text file.

As shown in Figure 1, the preferred embodiment process of the present invention is:

(1) set up a mark for each text file initial position, described mark information comprises: audio frequency or video signal, time identification corresponding with described text file; Described time identification is a time offset, promptly begins to play text The difference between the time of the file and the time when the corresponding audio or video file starts playing;

(2) set up a corresponding list for each audio or video file, store the mark of all text files corresponding to this audio or video file in the said corresponding list, arrange in order according to the time mark in the said mark;

(3) After receiving the playback request from the user, the mobile terminal reads the audio or video file to be played by the user;

(4) Judging whether the user has selected a text file to be played synchronously with the audio or video file, if the user has selected a text file to be played synchronously, put the marks of all text files selected by the user into the corresponding audio or video file In the list, go to step (6); if the user does not make a selection, go to step (5);

(5) search for all text files corresponding to the audio or video files to be played by the user, and put the identifiers of all text files searched into the corresponding list of the audio or video files;

(6) according to the time mark in all text file marks in the corresponding list, determine the time that all text files start playing, all marks in the list are arranged according to the order of start playing time;

(7) Read the audio or video file selected by the user, judge whether the corresponding list of the audio or video file is empty, if it is empty, start playing the audio or video file, and the step ends; if not empty, enter step (8);

(8) a timer is set, and the value of the timer is set to 0, and when starting to play audio or video files, the timer records the playing time;

(9) read the time point when the first text file in the corresponding list starts to play, compare with the counter value of the timer, when the counter value of the timer is equal to the time mark, start to play the first text file, and delete the identifier of the text file from the corresponding list;

(10) Judging whether the corresponding list is empty, if it is empty, the step ends, if not empty, return to step (9).
