Description

Event response method and display device

Technical Field

The present application relates to the field of television technologies, and in particular, to an event response method and a display device.

Background

A Hybrid Broadcast Broadband TV (HBBTV) application in a display device generally needs to respond to an event in the display device, for example, when a channel switching event in the display device is triggered, part of the HBBTV module needs to respond to the event, and perform operations such as updating related information according to a switched channel.

Currently, when a main program module of a display device detects an event, a callback function of each HBBTV module that needs to respond to the event is sequentially called, so that each HBBTV module responds to the event. In this process, for each HBBTV module, the main program module needs to call the callback function of the next HBBTV module after the execution of the callback function of the HBBTV module is completed, and if the callback function of a certain HBBTV module is blocked, the main program module cannot continue to call the callback functions of other HBBTV modules behind the HBBTV module, so that other HBBTV modules cannot respond to the event.

Disclosure of Invention

The embodiment of the application provides an event response method and display equipment, which are used for enabling each HBBTV module not to influence each other when responding to an event in the display equipment.

In a first aspect, there is provided a display device comprising:

a display;

a controller coupled to the display, comprising at least: the HBBTV broadcast system comprises a main program module and at least two mixed broadcast broadband television HBBTV modules; wherein,

the main program module is configured to, when an event is detected, find at least one event queue corresponding to the event from event queues pre-configured for each HBBTV module, and store the event into the corresponding event queue;

each HBBTV module is used for detecting a configured event queue, determining a configured calling function of the HBBTV module to be called according to the event type of a newly added event when detecting the newly added event in the configured event queue, and running the calling function according to the event parameter of the newly added event when the corresponding event parameter exists in the newly added event.

In a second aspect, an event response method is provided, which is applied to a display device, where the display device at least includes a main program module and at least two hybrid broadcast broadband television HBBTV modules, and the method includes:

when the main program module detects an event, at least one event queue corresponding to the event is searched from event queues pre-configured for each HBBTV module, and the event is stored in the corresponding event queue;

each HBBTV module detects an event queue configured by the HBBTV module, determines a calling function configured by the HBBTV module to be called according to the event type of a newly added event when the newly added event in the configured event queue is detected, and operates the calling function according to the event parameter of the newly added event when the corresponding event parameter exists in the newly added event.

In the above embodiment, the main program module only needs to store the event into the corresponding event queue configured for the HBBTV module when detecting the event, and each HBBTV module only needs to respond to the event stored in the event queue configured for the HBBTV module. Therefore, when responding to the event in the display device, the HBBTV modules do not influence each other, and even if the function called when one HBBTV module responds to the event is blocked, other HBBTV modules are not influenced.

To facilitate understanding of the above embodiments, an event response flow diagram is illustrated in FIGS. 2A-2B. Described below in connection with FIGS. 2A-2B by way of example:

in fig. 2A, module B, module C, and module D are all HBBTV modules. The module a, the module B, and the module C all need to respond to a channel switching type event (hereinafter, referred to as a channel switching event), and register their callback function a, callback function B, and callback function C in the main program module in advance, respectively. For the above channel switching event, in an embodiment, a channel switching instruction input by a user operating the control device may be used as a trigger for the channel switching event, where the channel switching instruction may be a key input instruction corresponding to a key on the control device (e.g., a "CH +" key/"CH-" key), and the channel switching event is triggered when the key input instruction corresponding to the key on the control device is received.

When a channel switching event in the display device is triggered, the main program module in the display device in fig. 2A needs to sequentially call the callback function a, the callback function B, and the callback function C, so that the module a, the module B, and the module C respond to the channel switching event. As shown in fig. 2A, when the callback function B of the module B is called, the callback function B needs to call the function D of the module D; for the callback function of each module, the main program module needs to call the callback function of the next module after the execution of the callback function is completed and a call result is returned.

If a certain callback function is blocked and cannot return a call result when the callback function B calls the function D in the flow shown in fig. 2A, as shown in fig. 2B, the main program cannot call the callback function C that should be called after the callback function B because the call result returned by the callback function B is not received, so that the module C corresponding to the callback function C cannot respond to the channel switching event.

As can be seen from the flow shown in fig. 2A-2B, when an event is triggered, the main program module sequentially calls the callback functions of the HBBTV modules corresponding to the event, so that the HBBTV modules are coupled when responding to the event in the display device, and if the callback function of a module called by the main program module is blocked and cannot be executed, the main program module cannot continue to call the callback function of the next module, so that the next module cannot respond to the event.

Moreover, since other functions may need to be called when the callback function is called, and other functions may also call other functions, the call chain may be relatively deep, and the blocking of any function in the call chain may cause the blocking of the callback function, which makes it difficult to find and repair the root of the blocking of the callback function in a short time, so that the next HBBTV module of the HBBTV module corresponding to the blocked callback function is continuously affected by the blocking.

Therefore, the application provides an event response method, so that the HBBTV module does not influence each other when responding to the event triggered in the display device. The following is described in connection with fig. 3:

referring to fig. 3, fig. 3 is a flowchart illustrating an event response method provided by an embodiment of the present application. As shown in fig. 3, the process may include the following steps:

step S41, when the main program module detects an event, finds at least one event queue corresponding to the event from the event queues pre-configured for each HBBTV module, and stores the event in the corresponding event queue.

For convenience of description, the event detected in this step S41 will be hereinafter referred to as a target event. In one example, the target event may be any event registered in the display device, such as a channel switching event instructing the display device to switch from a current channel to a target channel, a language switching event instructing the display device to switch a system language from a current language to a target language, and so on. Taking the channel switching event as an example, the main program module may perform a channel switching operation in response to the channel switching event, and perform the step S41, so that the HBBTV module may respond to the channel switching event.

The event queue in step S41 is an event queue configured by the HBBTV module, and in one example, before step S41 is executed, at least one event queue for storing events may be created and configured for each HBBTV module in the display device, so that each HBBTV module is configured with a different event queue. As an embodiment, if there is an HBBTV module that does not need to respond to an event in the display device, the event queue may be configured only for HBBTV modules other than the HBBTV module that need to respond to an event in the display device.

In creating each event queue, as one embodiment, the event queue may be assigned a queue ID that is used to distinguish the event queue from other event queues. As an embodiment, when configuring an event queue for any HBBTV module, the queue ID of the event queue may be recorded in the HBBTV module, so that the HBBTV module records the event queue as an event queue configured by itself.

The main program module finds at least one event queue corresponding to the event from the event queues pre-configured for each HBBTV module, and there are various implementation manners, which are described below with reference to the embodiments.

In one example, the main program module may receive event information sent by each HBBTV module, the event information including a queue ID of an event queue to which the HBBTV module is configured. When searching for the event queue corresponding to the target event, as an embodiment, the main program module may determine the event queue corresponding to each received queue ID as the event queue corresponding to the target event. Thus, the target event is stored in the event queue corresponding to each queue ID.

For any HBBTV module, as an embodiment, the HBBTV module may send event information including a queue ID of an event queue to which the HBBTV module is configured to the main program module after booting (for convenience of description, this step is described as registering the event queue with the main program module in the following embodiments). Specifically, the starting of the HBBTV module herein may be the first starting of the HBBTV module in the display device, or may be each starting of the HBBTV module in the display device. For one embodiment, when the HBBTV module stops operating, a logout message may be sent to the main program module, where the logout message includes the queue ID of the event queue to which the HBBTV module is configured, so that the main program module deletes the recorded queue ID. As another example, any HBBTV module may register the queue ID of the configured event queue to the main program module after being configured with the event queue.

In another example, the number of registered events in the display device is large, and when the HBBTV module is actually applied, only part of the events need to respond. The main program module may receive event information sent by each HBBTV module, where the event information may include a queue ID of an event queue configured by the HBBTV module and an event type of an event that the HBBTV module needs to respond to, that is, may include a correspondence between the queue ID of the event queue configured by the HBBTV module and the event type of the event that the HBBTV module needs to respond to.

When searching for the event queue corresponding to the target event, as an embodiment, the main program module may find a queue ID having a corresponding relationship with the event type according to the event type of the target event, and determine the event queue corresponding to the queue ID as the event queue corresponding to the target event. Thus, the target event is deposited into the event queue configured by the HBBTV module which needs to respond to the target event.

In another example, the above two examples may be used in combination, and specifically, the main program module may receive event information sent by each HBBTV module, where the event information may include only a queue ID of an event queue configured by the HBBTV module, and may also include a correspondence between the queue ID of the event queue configured by the HBBTV module and an event type of an event to which the HBBTV module needs to respond.

When searching for an event queue corresponding to a target event, as an embodiment, for a queue ID having a correspondence with an event type, searching for a queue ID having a correspondence with the event type according to the event type of the target event, and determining an event queue corresponding to the queue ID as an event queue corresponding to the target event; and directly determining the event queue corresponding to the queue ID as the event queue corresponding to the target event for the queue ID which does not have the corresponding relation with the event type.

In the above embodiments, the queue ID of the event queue configured for each HBBTV module, and the correspondence between the queue ID of the event queue configured for each HBBTV module and the event type of the event that the HBBTV module needs to respond to may also be recorded to the main program module by other means (such as manual configuration).

In a specific implementation, there are various implementation manners of step S41, which are described below with reference to fig. 5 for example, and are not described herein again.

In step S42, each HBBTV module calls the configured calling function of the HBBTV module according to the event type of the newly added event when detecting the newly added event in the event queue configured by the HBBTV module.

In one example, each HBBTV module configured with an event queue may retrieve a deposited event from the configured event queue and respond to the event. As an embodiment, when the event queue configured by the HBBTV module does not store an event, the HBBTV module may detect whether an event is newly added to the configured event queue in real time, so that when an event is newly stored to the event queue, the event can be timely taken out and responded. In one embodiment, the HBBTV module is provided with an event detection thread for detecting in real time whether an event is newly added to the configured event queue.

In one example, when any HBBTV module detects a newly added event in an event queue in which the HBBTV module is configured, the HBBTV module may determine a configured calling function that needs to be called according to an event type of the newly added event. As an embodiment, when there is a corresponding event parameter for the newly added event, the HBBTV module runs the determined call function according to the event parameter. For one embodiment, when there is no corresponding event parameter for the newly added event, the HBBTV module may directly run the determined calling function.

Whether the newly added event corresponds to the event parameter or not and what event parameter corresponds to the newly added event can be configured in the display device in advance according to actual needs. For example, for the event type of channel switching, the event parameter corresponding to the event of the event type may be configured as the relevant information of the switched channel, so that when the HBBTV module responds to the channel switching event, the HBBTV module may run a call function according to the relevant information of the switched channel, so as to achieve the effects of updating the channel information in the user interface of the HBBTV application to the relevant information of the switched channel, and the like.

As an embodiment, if the event information sent by the HBBTV module to the main program module includes a correspondence between a queue ID of an event queue configured by the HBBTV module and an event type of an event that the HBBTV module needs to respond to, the newly added event in the event queue configured by the HBBTV module is an event that the HBBTV module needs to respond to, and the HBBTV module can directly determine a calling function that needs to be called for the newly added event in the event queue configured by the HBBTV module.

As an embodiment, if the event information sent by the HBBTV module to the main program does not include a correspondence between a queue ID of an event queue configured by the HBBTV module and an event type of an event that the HBBTV module needs to respond to, a newly added event in the event queue configured by the HBBTV module is not necessarily an event that the HBBTV module needs to respond to, and when detecting a newly added event in the configured event queue, the HBBTV module may first determine whether the newly added event is an event that the HBBTV module needs to respond to, specifically, may determine whether the event type of the newly added event is an event type of an event that the HBBTV module needs to respond to, and if the determination result is yes, determine an already configured calling function of the HBBTV module that needs to be called according to the event type of the newly added event. For one embodiment, in the case where the determination result is negative, the HBBTV module may discard the newly added event.

The flow shown in fig. 3 is completed.

Through the flow shown in fig. 3, each HBBTV module only needs to call a call function of a response according to an event stored in the event queue configured for each HBBTV module to respond to the event, and each HBBTV module does not affect each other, and even if a certain HBBTV module blocks the call function called by the event, other HBBTV modules are not affected.

To facilitate understanding of the flow and benefits shown in fig. 3, another event response flow diagram is illustrated in fig. 4A-4B, which is described below in connection with fig. 4A-4B by way of example:

in fig. 4A, module B, module C, and module D are all HBBTV modules, and module a, module B, and module C are configured with event queue a, event queue B, and event queue C, respectively. The module a, the module B and the module C all need to respond to a channel switching event, and respectively register the corresponding relationship between the queue ID of the event queue a, the queue ID of the event queue B and the queue ID of the event queue C corresponding to the module a and the module C and the channel switching event type to the main program module in advance.

When the main program module detects a channel switching event, for example, when a channel switching instruction is received, as shown in fig. 4A, the main program module stores the channel switching event in the event queue a, the event queue B, and the event queue C, respectively, so that the module a, the module B, and the module C take out the channel switching event from their corresponding event queues, respectively, and respond to the channel switching event. When the module B responds to the channel switching event, the function D of the module D needs to be called.

If the function D called by the module B is blocked and the call result cannot be returned in the flow shown in fig. 4A, as shown in fig. 4B, the module B cannot receive the call result returned by the module D, and the module C is not affected by the blocking of the function D and can still respond to the channel switching event stored in the event queue C corresponding to the module C.

As can be seen from the processes shown in fig. 4A-4B, by applying the event response method provided in the embodiment of the present application, each HBBTV module may not affect each other when responding to an event triggered in a display device, and even if a function called when a certain HBBTV module responds to an event is blocked, other modules may not be affected to respond to the event.

Step S41 in the above-described flow shown in fig. 3 is described below by way of example with reference to fig. 5.

Referring to fig. 5, an implementation flowchart of step S41 is exemplarily shown in fig. 5. In one example, before the flow shown in fig. 5 is executed, each HBBTV module has sent the corresponding relationship between the queue ID of the configured event queue and the event type of the event that needs to be responded to the main program module. As shown in fig. 5, the process may include the following steps:

in step S51, when detecting an event, the main program module determines at least one queue ID having a correspondence relationship with the event type from the received correspondence relationship between the queue ID and the event type according to the event type of the event.

In step S52, for each determined queue ID, the main program module generates an event according to the event type of the detected event, and stores the generated event in the event queue corresponding to the queue ID.

In one example, the event generated by the main program module may include at least an event type and a parameter corresponding to the event. Taking a channel switching event as an example, the event parameter corresponding to the event may be related information of a channel to be switched to, where the related information may include: original Network Identification (ONID), Transport Stream Identification (TSID), Service Identification (SID), and the like.

To facilitate understanding of the present step S52, a simple example is given below. Taking the event detected by the main program module as a channel switching event and the event parameter corresponding to the event is the related information of the channel a as an example, the main program module may generate an event for each queue ID determined in step S51, where the event includes the event type of channel switching and the event parameter as the related information of the channel a, and store the generated event in the event queue corresponding to the queue ID.

To facilitate understanding of the events generated by the main program module, the data structure of the generated events is exemplarily shown by table 1 below:

string eventName；
	int eventType；
Type1 eventParam1；
	Type2 eventParam2；
……
	TypeN eventParamN；

TABLE 1

As shown in table 1, the data structure of the event mainly includes: eventName (event name), eventType (event type), and eventParam (event parameter). The event name and the event type are used for uniquely identifying the event, each module in the display equipment mainly identifies different events according to the event type, and the different events are mainly identified according to the event name during manual testing; the event parameters 1-N are event parameters that need to be transmitted by the event, and are filled in by the main program module according to the event parameters actually corresponding to the event, and if the event does not correspond to the event parameters, the event parameters in table 1 may be empty.

This completes the description of the flow shown in fig. 5.

It should be noted that the flow shown in fig. 5 is only an example of a specific implementation of the step S41, and other implementation manners may exist in practical application, which are not listed here.

As described in the above embodiments, when an event occurs, the main program module in the display device stores the event in the corresponding event queue, and each HBBTV module only needs to respond to the event stored in the event queue configured for the HBBTV module, so that when responding to the event in the display device, each HBBTV module does not affect each other, and even if a function called when a certain HBBTV module responds to the event is blocked, other HBBTV modules are not affected.
