the method for operating the J2ME audio file by the iptv set top box comprises the following steps:

transplanting an jvm virtual machine supporting an Android system;

step two, packing the virtual machine into a so library form, packing the so library into an apk, and arranging the apk into a system of the IPTV set top box;

step three, the IPTV starts to normally enter a special Java game area of the value added service, the IPTV browser downloads jar, jad and audio files required by the Java game, and the jar, jad and audio files are placed in a specified file directory operated by the virtual machine;

step four, after downloading the Java game, clicking a confirmation button on the game interface, pulling jvm the virtual machine running apk by the IPTV browser, and entering a virtual machine running process;

step five, the jvm virtual machine analyzes the execution jar and jad files, judges whether audio data of external equipment exist, if so, the external audio data are used, if not, the audio data specified by the Java game jad are analyzed, and the Java application layer of the game apk is transmitted according to the defined jni interface to play audio and video;

step six, pressing a return button of the remote controller after the game is finished, closing the running of the Java virtual machine after the virtual machine apk receives the key information, closing the playing of the audio data, returning to the running interface of the IPTV browser again, and finishing the playing of the J2ME audio file.

Furthermore, the transplantation supports jvm virtual machines of Android systems, and is used for supporting JSR75 and JSR135, supporting a multi-CPU mode, and realizing the binding function of the designated CPU.

Furthermore, the audio module exists in apk form, is associated with jvm in jni form, extracts jvm the analyzed audio data, and plays according to the extracted audio data.

Furthermore, the IPTV browser downloads jar, jad and audio files required by the Java game, and also comprises the steps of firstly operating the JVM, binding the CPU, and then downloading jar, jad and audio files required by the Java game after the binding of the CPU is completed.

Further, the playing is performed according to the extracted audio data, specifically, the extracted audio data is sent to the playing unit in a streaming form for audio playing.

The invention has the beneficial effects that: the scheme provided by the invention can independently run the audio files in the j2me environment of the set-top box, can use the self-contained audio data of the j2me game, and can also use an external medium, such as a U disk, to load the audio files which are loved by the user.

Detailed Description

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

As shown in fig. 1, a method for implementing an iptv set-top box to run J2ME audio files includes a processing system for J2ME audio files, where the processing system for J2ME audio files includes a virtual machine module, a data acquisition module, and an audio module;

transplanting an jvm virtual machine supporting an Android system;

The transplantation supports jvm virtual machines of an Android system, is used for supporting JSR75 and JSR135, supports a multi-CPU mode and realizes the binding function of a designated CPU.

The audio module exists in an apk form, is associated with jvm in a jni form, extracts jvm analyzed audio data, and plays the audio data according to the extracted audio data.

The IPTV browser downloads jar, jad and audio files required by the Java game, and also comprises the steps of firstly operating the JVM, binding the CPU, and then downloading the jar, jad and audio files required by the Java game after the binding of the CPU is completed.

The playing is performed according to the extracted audio data, specifically, the extracted audio data is sent to the playing unit in a streaming form for audio playing.

Specifically, the technical scheme comprises the following modules: an environment for operating J2ME audio data is jvm supporting an Android platform operating environment based on PhoneME Advanced transplantation, and a virtual machine jvm generated by supporting JSR75 and JSR135 needs to exist in a so library form so as to be called in a set-top box. The game downloading module IPTV browser downloads jar and jad packages required by the Java game and corresponding audio files to a specified file directory remotely through JavaScript.

And an audio playing module which exists in the apk form and is associated with JVM in the jni form, and the audio data analyzed by the JVM is taken out for playing.

The specific implementation process is as follows:

1. the jvm virtual machine supporting the Android system is transplanted, and the support of JRS75 and JRS135 is realized

2. Packing the virtual machine into a so library form, packing the so library into an apk, and arranging the apk into a system of the IPTV set-top box

3. IPTV starts to normally enter a Java game area of the value added service, and the browser downloads jar, jad and audio files required by the Java game and puts the jar, the jad and the audio files into a position specified by the running of the virtual machine

4. After the downloading is finished, the game interface clicks a confirmation button, the IPTV pulls up the virtual machine running apk, and the virtual machine running process is entered

5. The virtual machine analyzes the execution jar and jad files, judges whether audio data of the external equipment exist or not, if so, the external audio data are preferentially used, if not, the audio data specified by the Java game jad are analyzed, and the audio and video are played by a Java application layer of the game apk through a jni interface defined in advance.

6. And pressing a return button of the remote controller after the game is finished, and after the virtual machine apk receives the key information, considering that the operation is finished, closing the operation of the Java virtual machine, closing the playing of the audio data, and returning to the operation interface of the IPTV again.
