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
The present invention relates to a kind of multimedia function extended method, particularly a kind of based on the method for expanding system-level multimedia functions that shows layering.
Background technology
Expand for multimedia function at present, general implementation method is by the DSP decoding chip being installed on original system board or being changed the more powerful video card of function and realize, but relate to motherboard design, driving such as writes at the field, exist the exploitation debugging difficulty big, the not enough shortcoming of function expansion flexibility.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that can make things convenient for, expand the multi-media player function of original system flexibly.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of based on the method for expanding system-level multimedia functions that shows layering, it comprises following steps:
(1) two operating systems of configuration: main system and from system, two system's independent operatings, and by network two systems are connected:
Main system: computing function is powerful, is applicable to except that multimedia decoding and the Desktop Computing showing, operation remote desktop server and order send client on the main system;
From system: multimedia handle and graphics calculations powerful, be applicable to multi-media decoding and encoding and graphical display, OSD layer and VIDEO layer and network function are supported in the demonstration of this system at least, from system's operation remote desktop client and a based on network order reception server, display is connected on system;
(2) with main system, from system start-up,, by remote desktop client login main system the desktop of main system is presented on the local OSD layer from system, and handle official business, ordinary desktop such as browse network or file operation use;
(3) in the time of play multimedia files, be presented on the VIDEO layer from the multimedia of system, the play command that sends the order transmitting terminal of main system arrives from system, this play command is a bidding protocol of appointing, the address that comprises the file that to play, the playing program played file is moved in positions of broadcast window etc. and the concrete relevant information of player after system receives order; Situation for the file of this locality is play needs to rewrite the playing program of main system, and the broadcast of playing program is partly changed into to sending play command from server; For the video that embeds in the webpage, need write browser plug-in, this plug-in unit sends play command to from the system command reception server, starts player at corresponding browser window displaying video.
The present invention can make things convenient for, expand flexibly the multi-media player function of original main system, the function expansion flexibly, reduce the redesign mainboard, write work such as driving again, thereby avoid steps such as exploitation, debugging, this thought also can be applied to the expansion of other functions.
Embodiment
Include two independently operating systems in this method simultaneously, two systemic-functions are independent and complementary, and one of them is a main system, and another is from system.Powerful from multimedia system, by demonstration being distributed on the different layers, realize the purpose of seamless expansion main system multimedia function.Main system among the present invention and from system's independent operating, the demonstration of two systems is distributed in different layers.
The main system computing function is powerful, is applicable to except that multimedia decoding and the Desktop Computing field showing; Powerful from multimedia system processing and graphics calculations, be applicable to multi-media decoding and encoding and graphical display.The desktop application of main system is presented on the OSD layer, is presented on the VIDEO layer from the multimedia of system.
When the operation common table top is used, finish by main system; When play multimedia files, switch to from system and finish, main system with from system by the communicate by letter seamless switching of realization task of network or other modes.
Be that example describes method of the present invention with Godson 8089 ease jade for asking rain notebooks and SMP8655 multimedia high definition player below, following Godson 8089 ease jade for asking rain notebooks, SMP8655 multimedia high definition player are called for short 8089 and 8655.
8089 what adopt is that plate carries the low-power consumption integrated graphics card, be applicable to the ordinary desktop display application, can not play high definition videos such as 720P, the 8655th, a high definition is play scheme, and the high definition ability to play is stronger, shows to support OSD layer and VIDOE layer, two systems can both the independent operating linux system, operation VNC server and play command client on 8089, operation VNC client and play command service end on 8655 are connected to display on 8655.
After the system start-up, 8655 VNC client is from the VNC server that is dynamically connected on 8089, and the desktop 8089 is presented on 8655 the OSD layer, the play command service end of the play command client connection 8655 on 8089.By the VNC client, the user operates 8089 and realizes office software, browser, desktop application such as file operation.
During playing video file, 8089 start the playing program interface, and by the play command client file path of the position of broadcast window, size, broadcast and other play parameter are sent to 8655,8655 and start playing programs, in the corresponding position of VIDEO layer played file.
The present invention has expanded 8089 high definition ability to play, makes 8089 to possess the ability of playing high definition videos such as 720P.
The foregoing description does not limit the present invention in any way; every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention; the present invention expands the multimedia function except being applicable to, the task division of labor, the thought of switching also are applicable to other functions of expansion.
