Step（1）, the Linux_TVOS bridges that linux system is connected with TVOS systems are established, Linux_TVOS bridges
Linux ends are connected with the server in linux system or client, TVOS ends and corresponding client or clothes in TVOS systems
Business device is connected, and wherein Linux system server is corresponding with TVOS system clients, TVOS system servers and Linux systems
Client of uniting is corresponding；
Step（2）, after the startup of TVOS systems, register the TVOS ends server of Linux_TVOS bridges；
Step（3）If succeeding in registration, operation TVOS ends server, start Linux ends server, monitoring information；If registration
Failure, exits TVOS systems；
Step（4）, it is right when client call request occur in the TVOS ends or Linux ends that listen to Linux_TVOS bridges
The server answered receives request；
Step（5）, corresponding server carries out protocol analysis to the call request information for receiving client, and according to association
View is handled, and result is fed back to the client for sending call request；
Step（6）, after TVOS system closedowns, stop and nullify the server of Linux_TVOS bridges.
Application method of the foregoing linux system software module in TVOS systems, it is characterised in that：The step（1）
The process for establishing the Linux_TVOS bridges that linux system is connected with TVOS systems is to establish between client and server
Invocation protocol, invocation protocol is identical with the interface function that the software module under linux system provides, and invocation protocol includes agreement letter
Several ID, each function parameter sequence and return values, the ID of the protocol function, each function parameter sequence are passed through by client
Linux_TVOS bridges are delivered to server, and return value is delivered to client by server, invocation protocol by shared drive from
One end of Linux_TVOS bridges is delivered to the other end.
Application method of the foregoing linux system software module in TVOS systems, it is characterised in that：The step（5）
Server carries out protocol analysis to the client call solicited message of reception, and is handled according to agreement, provided with synchronous and different
Walk two kinds of processing modes：Synchronization process mode, which is that server feeds back to result by return value, sends call request
Client；Under asynchronous process mode, the call request for the client that server passes through this side, result is fed back into offside
Server, the server of offside is to using feedback processing result.
The beneficial effects of the invention are as follows：Application method of the linux system software module of the present invention in TVOS systems, builds
Found Linxu_TVOS bridges, also known as LTTB (Linux To TVOS Bridge, Linux to TVOS bridge), realize TVOS systems and
Mutually called between two kinds of different C java standard libraries under linux system, the software mould compiled under the traditional linux system of convenient use
Block, save trouble and labor, there is the characteristics of cross operating system calling, across compiling system calling, reliability are high and stability is high, have good
Good application prospect.
Brief description of the drawings
Fig. 1 is the flow chart of application method of the linux system software module of the present invention in TVOS systems.
Fig. 2 is the schematic diagram of the server sync processing mode of the present invention.
