Detailed Description
in order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention provides a flow chart of a preferred embodiment of a multi-mode set-top box program filtering method, as shown in fig. 1, wherein the method comprises:
and S100, acquiring and storing the connection state of each front-end signal line in the multi-mode set-top box at a preset time interval after the multi-mode set-top box is started.
in specific implementation, the multi-mode set top box has 3 modes, namely DVB-S satellite transmission, DVB-C cable transmission and DVB-T ground transmission. If the current 3 modes are all in the connected state, the programs searched by each front-end type will be accumulated together much. The multimode set-top box acquires the connection state of each front-end signal wire at intervals of preset time and stores the connection state for comparing with the connection state acquired next time. Wherein the predetermined time is preferably 1-3 min.
in a further embodiment, step S100 further includes, before:
Step S1, a register is set in the multi-mode set-top box in advance for storing the connection status of each front-end signal line in the multi-mode set-top box.
In specific implementation, a connection state for storing three front-end signal lines in the multimode set-top box is set in the multimode set-top box in advance, and different states are represented by different values respectively. When the connection state of the front-end signal changes, the value in the register also changes correspondingly.
In a further embodiment, as shown in fig. 2, step S100 specifically includes:
step S101, reading a numerical value in a register in the multi-mode set-top box every other preset time after the multi-mode set-top box is started;
And S102, analyzing the connection state of each front-end signal line in the multimode set-top box according to the numerical value in the register and storing the analysis result.
in specific implementation, after the multi-mode set top box is started, data are read from a register in the multi-mode set top box every 3-5 min, and corresponding signal connection state parameters in the register are analyzed and stored.
Step S200, when detecting that the connection state of each front-end signal wire obtained currently changes compared with the connection state of each front-end signal wire obtained last time, obtaining the type of the front-end signal wire of which the signal connection state is disconnected.
in specific implementation, after a new front-end signal connection state is obtained each time, the state is compared with the previous state, and if the state is found to be changed, the current front ends are known to be in the connection state and the front ends are known to be in the disconnection state according to the signal connection state parameters of the register.
In a further embodiment, after step S200, the method further includes:
Step S201, when detecting that all front end signal line types in the multi-mode set-top box are in the disconnection state, the multi-mode set-top box menu prompts that all signal lines are in the disconnection state.
In the specific implementation, if an extreme condition is met: if all the signal lines at the front end are not connected, the memory space B does not contain any program information, and when the situation occurs, a multi-set top box menu system is needed to prompt a user that all the signal lines are not connected and the program can be played only by connecting the signal lines.
And step S300, acquiring an original program in a program database of the multimode set-top box, and filtering out a program corresponding to the type of the disconnected front-end signal line in the original program.
In specific implementation, all original programs in a program database of the multimode set-top box are obtained, the currently disconnected front-end type is analyzed according to the previous analysis, all program information of the program database is filtered to remove programs corresponding to the disconnected front-end type, and the rest programs are normally connected programs, so that the signal without signal connection is eliminated, and the time for switching to visible programs by a user is reduced.
in a further embodiment, as shown in fig. 3, step S300 specifically includes:
Step S301, updating a program database in the multi-mode set top box according to an operation instruction input by a user;
Step S302, an original program in the updated program database is obtained, a target program is generated by filtering a program corresponding to the type of the disconnected front-end signal line in the original program, and the target program is used as a program source when the multi-mode set top box switches programs or displays a program list.
in specific implementation, after the multi-mode set-top box operates, two memory spaces A and B are firstly allocated, the step specifically comprises two tasks, wherein the first task is responsible for checking whether a program database is updated, the reason for updating the database is mainly that a user searches programs or edits programs again (for example, the user deletes a certain program), once the programs are updated, the content in the memory A needs to be refreshed, all the latest programs in the memory A are ensured, and meanwhile, a message is sent to inform the second task that the program information is changed. And after the task two is operated, receiving the information from the signal connection state and the task one, if the information is received, firstly copying the data in the memory A to the memory B to ensure that the current database in the memory B contains the latest all programs, then analyzing the current signal connection state information, analyzing the current disconnected front-end type, and simultaneously processing all program information in the memory B to filter the programs corresponding to the disconnected front-end type. Therefore, the programs with normal signal connection in the memory B can be ensured in real time, and all program sources come from the programs in the memory B when the user switches the programs in a full screen mode or displays a program list, so that the programs without signal connection are eliminated, and the processing effect is optimized.
The invention also provides a flow chart of a specific application embodiment of the multi-mode set-top box program filtering method, wherein the specified application refers to a music player for example, as shown in fig. 4, the method comprises the following steps:
Step S10, start;
step S20, allocating memory spaces A and B, and then executing step S30 and step S31;
Step S30, starting a task I;
Step S40, monitoring database programs;
Step S50, judging whether there is updating, if yes, executing step S60, if no, executing step S40;
step S60, updating the content in the memory space A;
Step S70, sending a message to task II;
Step S31, starting a task II;
step S41, receiving a task I and a front-end state monitoring message;
Step S51, judging whether the message is received, if yes, executing step S61, if no, executing step S41;
Step S61, copying the content in the memory A to the memory B;
Step S71, analyzing the signal connection state information to obtain the type of the disconnection front end;
Step S81, processing and filtering program data in the memory B;
Step S91, determining whether the program number is zero, if yes, executing step S92, and if no, executing step S41;
Step S92, the menu prompts the user to insert a signal line, and then step S41 is executed.
the method can monitor the connection state of each front end of the current multi-mode set top box in real time, automatically filter out programs without signal line connection, and ensure that a user can display a program list in a full screen mode or through a remote controller when switching the programs up and down in the program list without prompting the condition of no signal caused by the problem of signal line connection. Due to the reduction of the number of times of trying to lock the screen when the system is invalid, the system operation efficiency is improved, and unnecessary waiting time of a user is reduced. In addition, the scheme does not need a user to know the DVB transmission standard to a certain extent, and programs can be intelligently filtered without selecting the front-end type through a menu, so that the intelligent DVB transmission system is suitable for people of all ages, is easy to use and is more intelligent.
