Embodiment Construction

[0011] The method also involves the operation of two independent operating systems, the two systems are independent and complementary in function, one of which is a master system and the other is a slave system. The multimedia function of the secondary system is powerful, and the purpose of seamlessly expanding the multimedia function of the main system is realized by distributing the display on different layers. The master system and the slave system in the present invention operate independently, and the displays of the two systems are distributed in different layers.

[0012] The master system has powerful computing functions and is suitable for desktop computing fields other than multimedia decoding and display; the slave system has powerful multimedia processing and graphics computing functions and is suitable for multimedia codec and graphics display. The desktop application of the main system is displayed on the OSD layer, and the multimedia playback of the slave system...

Abstract

The invention discloses a method for expanding system-level multimedia functions on the basis of layered display. According to the method, two operating systems which are independent from and complementary to each other simultaneously operate, wherein one operating system constitutes a host system, whereas the other operating system constitutes a slave system having a powerful multimedia function. By allocating the display on different layers, particularly, displaying the desktop application of the host system on an OSD (on-screen display) layer and displaying the multimedia player services of the slave system on a VIDEO layer, the invention can achieve the purpose of expanding the multimedia functions of the host system in a seamless manner; and the operation of the common desktop application is completed by the host system, and the multimedia files are switched to the slave system for playing, so that the tasks can be switched between the host system and the slave system via networks or other communication methods in a seamless manner.

Description

technical field [0001] The invention relates to a multimedia function extension method, in particular to a system-level multimedia function extension method based on display layering. Background technique [0002] At present, the general implementation method for multimedia function expansion is to install a DSP decoding chip on the original system motherboard or replace it with a more powerful graphics card. However, it involves motherboard design, driver writing and other fields, and it is difficult to develop and debug, and the function expansion is flexible. The shortcomings of insufficient sex. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that can conveniently and flexibly expand the multimedia playing function of the original system. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a system-level multimedia function extension...
