Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0012] To implement the digital TV function on the Android system, you first need to understand the framework of the Android system. like figure 1 As shown, the Android system is divided into four layers:

[0013] The first layer: Linux operating system and drivers;

[0014] The second layer: local frame (also known as C frame);

[0015] The third layer: Java framework;

[0016] The fourth layer: Java applications.

[0017] From the perspective of the Linux operating system, the first level belongs to the kernel space, and the second, third, and fourth levels belong to the user space. The second and third layers are the interface between the native code layer (C / C++) and the Java code layer. Between the third layer and the fourth layer is the interface of the Android system API. For the development of Android applications, the content of...

Abstract

The invention discloses a method for achieving digital televisions in accordance to DVB standards in an Andriod system. The method is characterized by comprising the following steps: using a socket mode to achieve digital television functions in a second layer of the Andriod system; and providing the digital television functions achieved in the second layer for application programs in a Java application layer through a Java application program interface (API) for calling, achieving digital television functions in a C framework layer by using the socket mode, and providing the digital television functions achieved in the C framework layer for application programs in the Java application layer through the Java API for calling. Accordingly, a large number of digital television related applications can call the Java API directly; the problem that how Java applications achieve digital television software module functions by using a base layer C language through the Java API is solved; and development efficiency and portability of the Java applications are greatly improved.

Description

[0001] Technical Field The present invention relates to the technical field of digital television, and in particular to a method for implementing a digital television conforming to the DVB standard on an Android system. Background technique [0002] Android system (Android) is the name of the open source mobile phone operating system based on the Linux platform developed by Google. The platform consists of operating system, middleware, user interface and application software. It is the first truly open mobile software for mobile terminals. Due to its free, open source, and open features, it has become the number one smartphone operating system in just a few years. At the same time, many digital TV and set-top box manufacturers are flocking to Android, and have transplanted the Android system to digital TVs and set-top boxes. [0003] However, Android is a system specially developed for mobile phones, and its framework does not support digital TV playback. Domestic digital TV...
