Embodiment Construction

[0020] Please refer to figure 1 As shown, the present invention provides a kind of realization using state machine to construct TV software system

[0021] method, including the following steps:

[0022] Step 1: Create a state according to the TV software requirements;

[0023] Step 2: Create a state manager that manages the state;

[0024] Step 3: Build the TV software system.

[0025] Here are three basic concepts:

[0026] State (State): refers to a state of an object in its life cycle. An object in a certain state must meet certain conditions, perform certain actions, or wait for certain events.

[0027] Event (Event): Refers to those things that occupy a certain position in time and space and are meaningful to the state machine. Events usually cause state transitions, prompting the state machine to switch from one state to another.

[0028] Transition: refers to a relationship between two states, indicating that the object will perform certain actions in the first s...

Abstract

A method of using state unit to structure software system of TV set includes setting up state required by software of TV set; setting up state supervisor to manage said state and structuring software system of TV set.

Description

technical field [0001] The invention relates to the field of embedded operating systems, in particular to a method for constructing a television software system using a state machine. Background technique [0002] In the TV field, each TV program basically starts from initialization, displays the LOGO, displays the menu, and then officially runs the program. Multiple states may appear at the same time—for example, a menu pops up during the program. [0003] The traditional way to deal with multi-state is to use a large number of judgments, loops, and branch statements. The TV is initialized, and after exiting the LOGO state, it starts to cycle until a key is pressed; then the menu is displayed until the selection operation is completed. Every time the program loops, it must be checked whether the menu should be displayed or simply wait. Moreover, the part of the program that handles the event must also determine whether the input is a menu response or a program response. ...
