Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] see figure 1 As shown, the embodiment of the present invention provides a method for realizing mixed audio playback in a Java virtual machine, comprising the following steps:

[0039] S1. Use the extension component JSR135 of the Java virtual machine to obtain the KNI extension interface related to audio. The KNI extension interface in the Java virtual machine includes an audio playback control interface, a video playback control interface, and a volume interface, etc., and the KNI extension interface related to audio includes an audio playback control interface and a volume interface.

[0040] Since the Java virtual machine is a multi-system integrated system integrating multiple environments, here only the Qt (a cross-platform C++ graphical user interface application development framework) environment under the linux operati...

Abstract

The invention discloses a method and a system for realizing sound mixing play in a Java virtual machine, relating to the field of Java application. The method comprises the following steps: obtaining a KNI expansion interface related to audio by using an expansion part JSR135 (Java Specification Requests) of the Java virtual machine; realizing an audio play interface of hardware equipment according to the KNI expansion interface related to audio, wherein the KNI expansion interface is provided by the JSR135 part; supporting creation of two players and simultaneous play by the hardware equipment, realizing an audio playing interface by expanding of a software development kit based on the hardware equipment, initializing the hardware equipment, creating a main player and a slave player, realizing sound mixing play control of the main player and the slave player; and compiling the expansion part JSR135 into the Java virtual machine, and generating a Java virtual machine client supporting audio play and sound mixing play. The Java virtual machine disclosed by the invention realizes sound mixing play by virtue of the main player and the slave player, and is capable of ensuring the stability of the sound mixing play.

Description

technical field [0001] The invention relates to the Java application field, in particular to a method and system for realizing audio mixing and playing in a Java virtual machine. Background technique [0002] IPTV (Internet Protocol Television, IP TV / Interactive Network TV) is a broadband cable TV network that integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. A new technology for service. IPTV services are roughly divided into two categories: basic services and value-added services. The basic services of IPTV refer to video content services based on audio-visual content, including live broadcast, on-demand, carousel, time-shifting, etc.; and value-added services of IPTV include games, Instant messaging, electronic payment, and karaoke, etc. Among them, games are divided into two types: web games and Java games, which are an important part of IPTV value-added services.
