Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic diagram of an architecture of an IPTV browser according to an embodiment of the present invention, where the IPTV browser includes a page loading module, an authentication module, a remote control key module, and a media playing module.
The page loading module is used for responding to the starting instruction, calling a webpage loading method of the chrome kernel through a self-defined ShellManager subclass to load an authentication page, and loading the IPTV page after the authentication is successful.
The authentication module is used for realizing an authentication object of the IPTV service platform through the ShellManager subclass in the authentication page and carrying out authentication operation.
And the remote control key module is used for processing a remote controller key event in the loaded page through the ShellManager subclass.
The media playing module is used for controlling media playing through a self-defined playing interface in the loaded page.
The page loading module and the authentication module are basic modules of the IPTV browser, and mainly function to respond to a start instruction, and upload information such as an account number, a password, a Set Top Box ID (Set Top Box ID), a mac (Media Access Control) address, and the like of the IPTV terminal to the IPTV service platform through an http request. After the verification of the IPTV service platform is passed, the address of the IPTV home page is issued to the IPTV terminal, and the IPTV terminal skips to the IPTV home page according to the guidance (location. After the subsequent user selects the link to be jumped through the remote controller, the IPTV terminal also sends an http request to the IPTV service platform through the page loading module, so as to realize the switching of the page.
In order to realize the http request function, the page loading module is to create a display window of a web page in the IPTV browser and load the page. The self-defined Shell manager subclass calls a launchShell method to create and display a webpage window, and binds the Shell class and calls a page loading method in the Shell class when the webpage window is created.
Fig. 2 shows a process of loading an authentication page by a page loading module, first, a pre-created shellmager subclass inherits a shellmager class of a Chromium core, the shellmager subclass calls a launchShell method of the shellmager class to realize display of a web page window, and the shellmager subclass is bound with the Shell class of the Chromium core in the process of executing the launchShell method. When an authentication address is requested, the authentication address can be acquired by the getActiveShell method of the Shell manager class, and the loadUrl (Page load) method of the Shell class is called to load the authentication address. The jump of the subsequent page can be realized by calling the original function of the chrome kernel by the ShellManager subclass.
The main functions of the Authentication module are to implement JS extension object Authentication (Authentication object defined in IPTV specification) required by IPTV service platform and two methods of this object: the IPTV service platform issues information such as a channel list and the like by an Authentication type SetConfig method, and acquires information of the IPTV terminal by the GetConfig method.
In the Authentication module, an addJavascript interface method is called by a customized ShellManager subclass to map an Authentication object (Authentication, JS extension object) to a customized Authentication class (JsAuthentication, which is a JAVA class), a getWebContents method of the Shell class is called to obtain a WebContents class, and the WebContents class and the customized Authentication class are associated by the Javascript Injector class.
FIG. 3 shows an Authentication process performed by an Authentication module, where a custom ShellManager subclass calls an addJavascript interface method to map Authentication to JsAuthentization; the self-defined Shell manager subclass calls the getWebContents method of the Shell class through the Shell manager class in FIG. 2 to obtain the WebContents class, then converts the WebContents into the Javascript Injector class through the frommWebContents method of the Javascript Injector class, and binds the self-defined JAVA class (JsAuthentification) and the converted Javascript Injector class through the addPossignatureInterfacefunction method of the Javascript Injector class, thereby completing the association of the WebContents and the Autoention. Thus, the IPTV service platform calls the evaluateJavaScript method of WebContents directly through the JS processing logic of the IPTV browser via the ShellManager subclass, thereby realizing the call of the SetConfig and GetConfig methods of Authentication.
The class of the Chromium core and the method thereof comprise:
shell class: getWebContents method;
WebContents class: evaluateJavaScript method;
javascript object class: the frommWebContents method and the addPossiblyUnsementer method.
The chrome core itself does not support remote control keys, but does support keyboard and mouse keys. Therefore, the key technology for realizing remote control key processing and the like is to convert the remote control keys into key values recognized by the IPTV platform and realize JS processing logic required to be executed by the corresponding key values.
The method comprises the steps that since the Shell manager class inherits the base class of the Shell manager of an Android system is a graph display View class of the Android system, a remote control key module responds to a remote controller key event, the Android system calls a DispatcKeyEvent method of the View class to send an obtained key value, a ContentViewCor receives the key value and calls a key value conversion method and a blink process, and JS processing logic corresponding to the key value in a page is executed; the method for dispatchKeyEvent in the ShellManager subclass receives key values of the keys and processes the specified key values, and JS processing logic corresponding to the keys in the page is achieved. The JS processing logic is a JS script provided by the IPTV service platform.
Fig. 4 shows a process of the remote control key module responding to a remote control key event, when a user presses a key, the user may call a dispatckeyevent (distribution key message) method in View, reference is made to a KeyEvent (key value) in the Android system, at this time, both the dispatckeyevent methods in ContentViewCore and the shellmager subclass are called, and after the ContentViewCore receives the key, the ContentViewCore may first convert the key value in the Android system into a key value recognized by the IPTV service platform through the conversion of the keyscorodefromandoidkeycode (key value conversion) method, and then call a blink process to implement a JS processing logic corresponding to the key in the page. The dispatchKeyEvent method in the ShellManager subclass can perform special processing on some special keys, and the requirement of customizing the keys is met.
Wherein, the class and the process of the chromosome kernel include:
ContentViewCore: displaying the JAVA class of the webpage content, and inheriting from the View class;
blink Process: a browser rendering engine.
The media playing module is mainly used for realizing a channel for calling a local playing function by the IPTV service platform. The key technology mainly comprises two technologies: implementing the JS handling logic calls a Mediaplayer (name of JS extension object defined in IPTV specification) object; and calling local JAVA class JMediaplayer (the self-defined name of the JAVA class corresponding to the Mediaplayer in the kernel) by the Chromium kernel, and finally realizing the control function of local playing.
The media playing module is used for controlling media playing through a self-defined playing interface in the loaded page. The playing interface comprises a customized JNI class and a media playing class, and a media playing object and a playing control method which are created by using an interface definition language IDL (InterfaceDescription language), wherein the media playing object comprises a method for acquiring a sequence number of a local player and at least one of the following playing control methods: setting the video window position, playing from the beginning and joining the multicast.
In the first Process, a media playing object corresponding to the local player is created according to the media playing object, and the created media playing object adds a self-defined playing and controlling Communication method in a LocalFrameClient subclass and a RenderFrameImpl class through a LocalFrame class, and is used for transmitting a playing and controlling instruction between playing and controlling Communication methods corresponding to the RenderFrameHostImpl class through Inter-Process Communication (IPC).
In the second process, the renderframehostimipl class controls the playing of the native player through the play control method of the JNI class and the corresponding play control method in the media play class.
Fig. 5 shows a process of controlling local play by the media play module through the play interface, where the play interface mainly includes:
1) the MediaPlayer objects and the corresponding play control modes are added through IDL: getnative player instance id (get local player number), setVideoDisplayArea (set video window position), playFromStart (play from head), and joinChannel (join multicast), etc.
2) Native fmediameplayergetvalue method of self-built JNI class fhplayeye (JAVA class created in the chrome kernel corresponding to MediaPlayer object), fhMediaPlayerGetValue method of sub-class JSMediaplayer of fhplayeye, and onfhmemediaplayecontrol (function for communication) customized in RenderFrameHostImpl.
In fig. 5, first, when a page newly creates a MediaPlayer object by JS, since IPTV has a function of viewing a plurality of videos at the same time, the newly created MediaPlayer object is associated with a local player by a play id (player identification number); the MediaPlayer object adds MediaPlayerGetValue (a self-defined function name for communication) method in LocalFrameClient subclass and RenderFrameImpl class through LocalFrame class; then, the broadcast control instruction is sent to OnFhMediaPlayerControl (a self-defined function name for communication) in RenderFrameHostImpl through IPC communication, so as to realize communication of different processes; finally, a native fmediameplayerGetValue method of the self-built JNI type Fhpayer is called by the RenderFrameHostImpl, and a fhMediaplayerGetValue method of the JNI type Fhpayer is called to the JMediaPlayer subclass of the Fhpayer, so that the calling of a native player (native Player) is realized.
The class of the Chromium core and the method thereof comprise:
LocalFrameClient: the subclass of LocalFrame is mainly used for processing interprocess message communication;
RenderFrameImpl: class of user inter-process communication.
The embodiment of the invention shields the calling of the webkit interface in the frame layer of the Android system, and effectively reduces the condition that IPTV application cannot be normally used due to the upgrading of the Android system. The IPTV application (browser) only runs on the Android system, and the IPTV application can be run by any terminal installed with the Android system.
Referring to fig. 6, in an alternative embodiment, the IPTV browser further includes a focus navigation module and a media information module.
The focus navigation module is mainly used for controlling whether the IPTV service platform displays a focus frame or performs a default navigation function on the IPTV terminal. The key technology is to realize methods of disableDefaultNavigation (default focus Navigation is prohibited), enabledDefaultNavigation (default focus Navigation is enabled), disableHighliight (default focus frame is prohibited from being displayed), and enableHighliight (default focus frame is displayed) of a page calling an extension object Navigation (name of JS extension object defined in IPTV specification) through JS.
The focus navigation module is used for building a focus navigation object in a page newly according to a self-defined focus navigation object arranged in the DOMWindex class, transmitting a LocalFrame class name into the page, and calling a render process through the LocalFrame class to realize focus frame display and/or default navigation enabling; wherein, the focus navigation object is a JS extension object of an IPTV service platform realized by using an interface definition language IDL.
Fig. 7 shows a processing procedure of the focus Navigation module, which is to add a Navigation object (Navigation) in the domBindow class, and then add four methods to the Navigation object, where the four methods call a setSpatialNavigationEnabled method and a setFocusWidth method of the LocalFrame class according to the LocalFrame class transmitted when the Navigation object is created, and finally, the chrome kernel determines whether Navigation is needed or whether a focus frame needs to be drawn at a place where Navigation is needed or the focus frame needs to be drawn.
The class of the Chromium core and the method thereof comprise:
DOMWindow: in the JS grammar, the name of a C + + class in a chrome kernel corresponding to a global variable window;
LocalFrame: the class name corresponding to the html page in the chrome kernel includes setting whether the default navigation setspatialnavigationeenabled method is enabled and setting the default focus frame width setFocusWidth.
The media information processing module is mainly used for actively transmitting the locally played information (the state that the video is played to the head or the tail, and the like) to the IPTV platform. The key technology of the module is as follows: how to inform the IPTV platform of the local playing information through JAVA class; how the IPTV platform acquires the play information through a JS extended object Utility (JS extended object defined in the IPTV specification) object, the implementation manner of the JS extended object Utility is the same as that of the Authentication object, and details are not repeated.
The media information module is used for acquiring and storing the playing information from the local player through a self-defined Event class based on the playing information of the local player, and calling a dispatckeyEvent method of the ShellManager class to send a specified key value; the ContentViewCore acquires JS processing logic corresponding to the designated key value in the designated key value execution page, and the JS processing logic calls a blink process and a getEvent (media message acquisition) method of a JS extension object Utility to acquire stored playing information and execute corresponding operation, wherein the JS extension object Utility is realized through a ShellManager subclass.
Fig. 8 shows a processing procedure of the media information module, when the local player has play information to send to the IPTV service platform, the local player may call an addMediaEvent method of a custom message type Event to store the play information, then call a dispatcheyevent method of a shellmager subclass to send a specific key value (e.g., 768), at this time, the key value may be sent to a kernel via processing (blink process) of the remote control button module, then call JS processing logic of the key value of 768 in the page, the JS processing logic may obtain the play information previously stored by the addMediaEvent by calling a getEvent method of utiity, and then execute different commands according to different play information in the JS processing logic.
Referring to fig. 9, an embodiment of the present invention provides a method for implementing an IPTV browser page, where based on the IPTV browser of the foregoing embodiment, the method for implementing the IPTV browser page includes:
s110, the IPTV browser responds to the starting instruction and calls a webpage loading method of a chrome kernel to load an authentication page through a self-defined ShellManager subclass.
