Abstract
The invention discloses a kind of digital television devices browser and the extended methods of cross-page plane system event, it include: that module is uniformly processed in system event, for forwarding the system event messages received by websocket protocol, the method is the following steps are included: digital television devices built-in system event occurs, and sends system event for built-in system event and module is uniformly processed；System event is uniformly processed module and establishes connection, and it is forwarded to application layer by built-in system event；Internal system event is monitored and handled using JS code；Browser injection built-in system event is monitored and handled using JS code, the present invention solves the problems, such as the cumbersome and cross-page face of extension.
Description
Technical field
The present invention relates to digital television devices technical field, especially a kind of digital television devices browser and cross-page face
The extended method of system event.
Background technique
With the arrival of Internet era, digital television devices all have two-way and browser function substantially.DTV
Equal system events need processing in time and response, the way before based on browser environment expansion of digital television system event are all
Event methods and attribute are extended based on browser kernel, but this method, there are two main problems, one is to need to modify
Browser kernel extends corresponding attribute and method, and realization is relatively complicated and complicated, another is to cannot achieve cross-page face thing
Part is monitored and processing, needs to realize digital television system event monitoring processing code in each page, but for some thirds
Square application page is helpless.
Summary of the invention
To solve problems of the prior art, the object of the present invention is to provide a kind of digital television devices browser with
And the extended method of cross-page plane system event, solve the problems, such as the cumbersome and cross-page face of extension.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of digital television devices browser and cross-page
The extended method of plane system event, comprising: module is uniformly processed in system event, receives for being forwarded by websocket protocol
The system event messages arrived, the method the following steps are included:
Step S10, digital television devices built-in system event occurs, and sends system event system for built-in system event
One processing module；
Step S20, system event is uniformly processed module and establishes connection, and it is forwarded to application layer by built-in system event；
Step S30, internal system event is monitored and is handled using JS code；
Step S40, browser injection built-in system event is monitored and is handled using JS code.
As a preferred embodiment, the step S10 is specifically included:
Step S11, digital television devices built-in system event occurs；
Step S12, built-in system event is sent to system event by the message mechanism of system and module is uniformly processed.
As another preferred embodiment, the step S20 is specifically included:
Step S21, websocket server is established, the client of connection is recorded；
Step S22, the built-in system event message received is transmitted to all connections by websocket protocol
client。
As another preferred embodiment, the step S30 is specifically included:
Step S31, start websocket connection；
Step S32, websocket system event messages are monitored；
Step S33, parsing and processing DTV built-in system event message.
As another preferred embodiment, the step S40 is specifically included:
Step S41, start new page to be loaded into and judge whether to be loaded into new page, new page mark is set；
Step S42, it is loaded into if it is new page, loading internal system event is monitored and processing JS code.
As another preferred embodiment, the built-in system event includes CA event, tuning event, video thing
Part.
As another preferred embodiment, the built-in system event message uses JSON format.
The beneficial effects of the present invention are: the present invention, which is flutterred using websocket mechanism from browser application layer, obtains system event,
And realize that the mechanism of obtaining is flutterred in cross-page face automatically, solve the cross-page face of digital television devices browser, digital television system event
Extend cumbersome and cross-page face problem.
Detailed description of the invention
Fig. 1 is the flow diagram of the embodiment of the present invention；
Fig. 2 is the flow diagram that browser injects built-in system event in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is described in detail with reference to the accompanying drawing.
Embodiment
As shown in Figure 1, the extended method of a kind of digital television devices browser and cross-page plane system event, comprising: be
Module is uniformly processed in system event, for forwarding the system event messages received, the method packet by websocket protocol
Include following steps:
A, digital television devices built-in system event occurs, and built-in system incident is sent to system event by message mechanism
Module is uniformly processed:
A1. digital television devices occur；
A2. system sends unified receiving module for built-in system event by message mechanism, and code is as follows:
A3. unify receiving module and receive message, extract event content data；
B, system event is uniformly processed module and establishes connection, and it is forwarded to application layer by built-in system event:
B1. websocket server is established, the client of connection is recorded, code is as follows:
B2. the built-in system event message received is transmitted to by websocket protocol the client of all connections,
Local and other lan devices are supported to access DVB application simultaneously, the content of the present embodiment built-in system event message uses
JSON format, JSON are a kind of grammers of storage and exchange of texts information, it and XML characteristic having the same are a kind of data
Storage format, it is but smaller than XML, faster, be easier to people and write and read, be more easily generated and parse, code is as follows:
C, internal system event is monitored and handled using JS code: c1. starts websocket connection, and code is such as
Under:
C2. websocket system event messages are monitored, code is as follows:
B3. DTV built-in system event message is parsed and handles, signal code snippet is seen below:
D, as shown in Fig. 2, browser injection built-in system event is monitored and handled using JS code: d1. starts
New page is loaded into and judges whether to be loaded into new page, and new page mark is arranged, and code is as follows:
D2. it is loaded into if it is new page, loading internal system event is monitored and processing JS code, code are as follows:
A specific embodiment of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
