Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a starting method and a starting device of a set top box, which are used for accelerating the starting of the set top box, improving the user experience and providing a better service effect.
It should be noted that, before executing the starting method of the set-top box, an association list needs to be constructed. The associated linked list contains scheduling index information of the execution module, and is used for finding out the corresponding execution module to execute the starting process of the set top box.
Optionally, referring to fig. 1, one embodiment of generating the association linked list is:
s101, aiming at each service scene, constructing an execution module corresponding to each task included in the service scene.
Wherein the service scenario includes: and a plurality of service scenes in the starting process of the set top box.
In general, a business scenario may be: monitoring updating of PSISI table, monitoring private table information, monitoring upgrade flow information, filtering OC data flow, obtaining CA authentication information, one or any combination of multi-frequency point and multi-service requirements.
It should be noted that each service scenario includes at least one task, and a task requires at least one execution module to process the task.
And S102, loading the configuration item information of the execution module.
Wherein, the configuration item information may include: configuration information of transmission channels in Digital Video Broadcasting (DVB), for example: frequency points, symbol rate, transmission mode, etc.; information of the tables to be monitored, for example: packet Identification (PID), table Identification (Table Identification, table id), and the like; ordering priority information of the services; service context information or similar service context information.
It should be noted that each execution module includes these types of configuration item information, but the function of each execution module is different, and accordingly, the specific content of these types of configuration item information included in each execution module is also different.
And S103, configuring the function of the corresponding execution module by using the configuration item information.
And analyzing the configuration item information of the execution module, and setting the function of the execution module by using the configuration item information. Specifically, referring to fig. 2, after configuring the functions of the execution module, the execution module generally includes three parts, namely, a chain pointer, the functions of the execution module, and default parameters.
The chain pointer is determined according to configuration information of a transmission channel in DVB in the configuration item information and sequencing priority information of services, and the chain pointer is used for determining the association relation between tasks to be executed through frequency points in the chain pointer and the tasks. The incidence relation between the execution modules means that the execution module and the other execution module have the same frequency point and process the same task.
The functions of the execution module may be create, run, detect, terminate, and complete, etc. Specifically, the service context information or the similar service context information in the configuration item information is determined. For example, to create and run a task, two execution modules may be used for processing, one execution module is created, and the other execution module is run, and the two execution modules have an execution sequence, which is necessarily created first and then run.
The default parameters of the execution module can also be determined by the service scenario information or similar service scenario information in the configuration item information, or can be configured by the information provided by the set-top box.
It should be noted that the established execution modules can be managed and scheduled by an overall controller. The master controller can add or delete execution modules, and can also sequence and schedule tasks.
S104, establishing an association table of the scheduling index and the execution module with the configured function as the association table according to the configuration item information.
The scheduling index and the association table of the execution modules with the configured functions are used for explaining the execution sequence of the execution modules at the same frequency point and explaining the execution sequence of the execution modules at the same task.
The associated linked list connects the scheduling index with the execution module after the function configuration, and the execution module and the execution sequence of the execution module can be found out through the scheduling index. Specifically, the execution modules and the execution sequence thereof at the same frequency point, and the execution modules and the execution sequence thereof under the same task can be found.
The embodiment of the invention aims at each service scene, constructs the execution module corresponding to each task included in the service scene, introduces configuration item information to each execution module, and configures the function of each execution module. Different service scenes are processed through the execution module, the effect of high cohesion and low coupling is achieved, only the logic scheduling and execution module of the execution module needs to be processed, and the maintenance and the expansion of the codes are facilitated.
It should be further noted that after the association linked list is constructed, a task chain queue is also constructed, where the task chain queue includes multiple task linked lists arranged according to the execution priority order.
Each task linked list at least comprises one task, and the tasks are in the same priority level. The tasks included in the task chain table are basically the tasks involved in the set top box starting process. The priority level of the task is used for explaining the execution sequence of the task, and the higher the priority level is, the more the corresponding task needs to be executed.
Optionally, referring to fig. 3, one way of generating the task chain queue includes:
s301, at least one service included in each service scene is determined.
The set-top box needs to start a plurality of service scenarios, each service scenario includes at least one service, and first, the executed service and the execution sequence thereof need to be clarified.
S302, classifying the plurality of determined services according to the sequencing priority of the services, and sequencing the classified classes.
The service sequencing priority comprises the following steps:
setting tasks, special tasks and core tasks which are irrelevant to the frequency points as task classes of a first execution sequence;
setting tasks of the central frequency point and tasks with frequency locking execution time smaller than a first threshold value as task classes of a second execution sequence;
and setting the tasks with the conflict items and the tasks with the frequency locking execution time larger than a second threshold value as the task class of a third execution sequence.
The factors for determining the service sequencing priority order are as follows: whether the frequency point is irrelevant to the frequency point, whether the frequency point is a central frequency point, whether the frequency point is a main frequency point or a standby frequency point, whether the frequency point is a special service or not, and the length of the execution time of frequency locking.
It should be noted that the task class in the first execution order, the task class in the second execution order, and the task class in the third execution order are the execution priority order of the tasks, that is, the multiple task chain tables included in the task chain queue may be classified into the three task classes, and the three task classes have the execution sequence.
It can be known that, the sorting of the classified services means that the sorted services are imported into the task chain queue. In the task chain queue, the master controller can schedule the three types of task classes, that is, can schedule the ordered services.
Because the set-top box only has one demodulator and one demultiplexing, one demodulator can only lock one frequency point at any time, and one demultiplexing has a multipath channel and a multipath filter, tasks irrelevant to the frequency points can be executed concurrently, tasks at the same frequency point can also be executed concurrently, and under the condition of the same frequency point, no conflict item exists among the tasks.
The embodiment of the invention classifies and sequences the services, so that the set top box can be scheduled according to the optimal scheduling strategy in the starting process, thereby meeting the requirements of actual services.
Based on a task chain queue constructed in advance, the method for starting a set top box disclosed by the embodiment of the invention, as shown in fig. 4, includes:
s401, a task chain queue is obtained, wherein the task chain queue comprises a plurality of task chain tables which are arranged according to an execution priority sequence, and each task chain table comprises at least one task with the same priority.

S402, sequentially scheduling each task linked list according to the arrangement sequence of the task linked lists in the task chain queue.
That is, the first execution order task class, the second execution order task class, and the third execution order task class in the task chain queue are scheduled in sequence. As can be seen from fig. 5, the task classes in the first execution order are scheduled in sequence according to the execution priority order until the task classes in the third execution order are scheduled.
S403, acquiring at least one task included in the scheduled task linked list.
With reference to fig. 5, each task class includes at least one task, at least one task included in the task chain table that is scheduled is obtained, that is, at least one task included in each task class is obtained, and the order of obtaining the tasks is obtained according to the order of the execution priority, that is, at least one task included in the task classes from the task class in the first execution order to the task class in the third execution order is obtained in sequence.
S404, the acquired at least one task is executed concurrently.
The tasks included in the same task class are the tasks with the same priority, and the tasks with the same priority can be executed concurrently. That is, all tasks included in the same task class can be concurrently executed, and all tasks included in the three classes of task classes can be executed in order of execution priority. With reference to fig. 5, the tasks included in the same task class are the tasks with the same priority, and may be all the tasks included in the task class in the first execution order are the tasks with the same priority, and all the tasks in the task class are executed concurrently. Similarly, all tasks included in the task class in the second execution order are executed concurrently, and all tasks included in the task class in the third execution order are executed concurrently.
In addition, the embodiment of the invention can also check whether the task is executed, and if the task to be executed is not executed, the task is executed. The embodiment of the invention can also mark whether the execution time of the executed task is overtime.
According to the embodiment of the invention, at least one acquired task is executed concurrently, and when the set top box schedules and executes the task, the task can be executed concurrently, so that the time for starting the set top box is shortened, the user experience is improved, and a better service effect is provided.

Referring to fig. 7, F1, F2, and F3 in fig. 7 are different frequency point indexes, and S1, S2, and S3 are different task name indexes. If F1 is the frequency point of the first execution module, and the second and third execution modules with the same frequency point as the first execution module can be found. If S1 is the task name index of the second execution module, the second execution module and a third execution module with the same task name as the second execution module can be found. Meanwhile, the execution sequence of the first execution module, the second execution module and the third execution module can be determined.
