Abstract
The invention discloses a kind of browser and download, by data broadcast, the call method starting java application, java application is play by Cable holding wire in the way of OC (DSMCC Object Carousal) by the Data Frontend of digital television system, the html application on digital TV middleware is run at user terminal (DTV STB), digital TV middleware meeting automatic cutting-table is to the channel playing this java application, then middleware downloads the AIT table on this channel, resolve AIT table, judge whether the application currently started, if finding the java application to start, the then description according to AIT table, java application class file bag is downloaded to local by doLoad interface, then JavaVM starts the described java to start application by mainClassName。
Description
Technical field
The invention belongs to digital television techniques field, download, by data broadcast, the call method starting java application particularly to a kind of browser。
Background technology
In DTV overall transformation in the past few years, all kinds of Set Top Box millions that each radio and TV operator provides, owing to Set Top Box specification refines not, the disappearance middleware system support to the Set Top Box software and hardware unified platform and business, cause the contradiction between the function monotonicity of Set Top Box and the multiformity of market business demand, and in aggravation, set top box upgrading difficulty, user's viscosity gradually reduces, value-added service income is low, have a strong impact on the needs of business development under the integration of three networks, seriously constrain the strategic development of CHINA RFTCOM Co Ltd。
The business that middleware Technology is radio and TV operator provides a relatively uniform platform so that cross-domain business intercommunication becomes simpler。Abstract by bottom hardware resource of middleware Technology, it is provided that the support to the various application in upper strata。Middleware platform is responsible for shielding bottom hardware diversity, and is that upper strata api interface calls for third party's business module by underlying resource module abstracts。Meanwhile, terminal platform is the carrier that whole digital TV platform presents, and it is responsible for various data and the instruction that receiving front-end is broadcast, and carries out resolving and presenting。In middleware platform, terminal platform, while being responsible for basic audio and video playing, also is responsible for the application of receiving front-end broadcast, and the operation according to user runs these application so that carrying out of business is possibly realized。
The function of digital TV middleware strengthens day by day, and by original seeing merely, TV develops into use TV, uses TV to surf the web, program request film, and Query Information plays game etc., and the application of increasing TV platform is developed。The exploitation of TV applications has two ways, and one is html+javaScript mode, and two is the application using java language development。It requires that TV middleware possesses can start that management controls the management system of java application。
Along with the universal of DTV and popularization, have the valued added applications run on more digital TV platform and produce, make user pass through TV platform, obtain more information, entertain and exchange。The deployment of various valued added applications, upgrading, popularization etc., the management difficulty of operator certainly will be increased, it requires that middleware has and start more easily, run, the operating capability of unloading application。
Summary of the invention
It is an object of the invention to provide a kind of browser and download, by data broadcast, the call method starting java application so that this digital TV middleware has startup, management, controls the management function of java application。
The technical scheme is that, a kind of browser downloads, by data broadcast, the call method starting java application, java application is play by the Data Frontend of digital television system, with OC, namely the mode of (DSMCCObjectCarousal) is play by Cable holding wire, user terminal is to operate in the html application on digital TV middleware, by javascript interface AppManager.startAppName, according to parameter dvb three elements, described digital TV middleware switches to the channel downloading application, download, resolve the AIT table on this channel, judge whether the application currently started, if finding the java application to start, the then description according to AIT table, find mainClassName and the mainClassPath of main classes, java application class file bag is downloaded to local by the doLoad interface of DVBJProxyImp class, then the described java to start application is started again through mainClassName。
The application managements such as present invention achieves digital TV platform java application, broadcasting and TV front end broadcast system is broadcast by under cable holding wire, then passes through a simple html and describes the three elements of java application, complete the startup of this application, controls, destruction。
This method starting java application, it is based on the Java application of MHP (MultimediaHomePlatform) standard of following of JavaVM, it is the combination of method and the browser startup CDC/CLDCjava application process starting and downloading java application, is network data transmission (TCP/IP) and the combination of data broadcast object carousel transmission (DSMCCOC)。The method is meet the new middleware of integration of three networks specification, develops new application and provides conveniently。More convenient startup, manages new valued added applications。
Accompanying drawing explanation
Fig. 1 is the digital TV terminal Organization Chart in the embodiment of the present invention。
Fig. 2 is the digital TV middleware structural representation in the embodiment of the present invention。
The digital TV middleware that Fig. 3 is in the embodiment of the present invention realizes schematic flow sheet。
Detailed description of the invention
The system of the digital TV middleware of the present invention and structural representation are as illustrated in fig. 1 and 2。
As shown in Figure 3, a kind of browser of the present invention downloads, by data broadcast, the call method starting java application, the method starting java application quickly and easily, java application is play by Data Frontend, terminal is to operate in the html application on TV middleware, by a simple javascript interface AppManager.startAppName (inttsid, intonid, intserviceid, char*appName), by downloading AIT under corresponding frequency, find the java application to start。Description according to AIT table, finds mainClassName and the mainClassPath of main classes, downloads java application class file bag to local by the doLoad interface of DVBJProxyImp class, then starts this application again through mainClassName。
1, the webpage pattern starting Java application is as follows:
2, the AppManager. primary interface increased has:
A kind of browser of the present invention downloads, by data broadcast, the call method starting java application; solve the java application owing to the reason of history and technical development causes and html applies incompatible problem; protect the technological investment of client; facilitate the updating and management of operator; expand more new business for operator and eliminate obstacle; convenient in webpage startup java application, facilitate radio and TV operator to carry out the deployment of new valued added applications, upgrading and popularization etc.。
Claims (1)
1. a browser downloads, by data broadcast, the call method starting java application, it is characterized in that, java application is play by Cable holding wire in the way of " DSMCCObjectCarousal " by the Data Frontend of digital television system, run in the html application on digital TV middleware at user terminal, by javascript interface AppManager.startAppName, according to interface parameters dvb three elements, digital TV middleware meeting automatic cutting-table is to the channel playing this java application, then middleware downloads the AIT table on this channel, resolve AIT table, judge whether the application currently started,
If finding the java application to start, the then description according to AIT table, find mainClassName and the mainClassPath of main classes, downloading java application class file data bag to local internal memory by the doLoad interface of DVBJProxyImp class, then JavaVM can start the described java to start application again through mainClassName。
