Embodiment

[0021] The following describes the technical solution of the present invention by taking the state transition of the IP videophone as an example.

[0022] For IP videophone, the system usually runs GUI and V2oIP programs, that is, the system is in the videophone state. For other multimedia terminals, its normal state is to run the main program, which is generally a GUI program and a main application program of the system.

[0023] The 5 typical applications in IP videophone are:

[0024] GUI: Graphical user interface program, used for graphical operations;

[0025] V2oIP: video phone program, used for IP-based video / voice communication, this program occupies relatively less system resources when it resides in the background, but it will occupy a lot of system resources when performing video calls;

[0026] Browser: browser program, used to browse web page information;

[0027] Player: player program, used to play local movies or perform streaming media on demand;

[0028] ...

Abstract

The related running method for embedded multimedia terminal optimization based on IP network comprises: a. usually, system only uses one primary program for maintenance and management; b. fro state conversion, the primary program runs relative programs by recalling function way; and c. system automatic quits and releases resource. This invention saves system cost, and increases process capacity for multi-task business.

Description

technical field [0001] The invention relates to multimedia technology, in particular to a multi-task running method of a multimedia terminal. Background technique [0002] Multi-task parallelism has been widely used on X86 personal computers. Since the X86 personal computer system has relatively abundant resources (CPU, memory, graphics card, etc.), it can easily handle multiple parallel small and medium-sized applications. [0003] However, in the embedded field, especially in the field of civil consumer electronics such as IP-based embedded multimedia terminals, such as IP videophones, system resources, especially processor resources and memory resources, are relatively limited due to their sensitivity to cost. How to provide users with various application services as much as possible on the basis of limited system resources requires an optimal design of system resource utilization. Contents of the invention [0004] The technical problem to be solved by the present in...
