Technical Field
The invention relates to the field of IPTV set-top boxes, in particular to a method and a system for processing a JavaScript extension object of an IPTV browser.
Background
With the continuous improvement of the basic network and the improvement of the network quality in China, video terminal products developed by operators of telecom, mobile, Unicom, radio and television and the like based on the basic network are successively released, wherein the IPTV set top box is greatly developed, but simultaneously, with the gradual saturation of the market, the development of the IPTV set top box gradually changes from the mode of market development, quantity expansion and the mode that the operators increase the respective user scale, and gradually changes to the direction of improving the content quality of users and reducing the operation cost.
Generally, a set-top box terminal device bears an IPTV EPG service, for this terminal product, the hardware cost and software development cost of an IPTV set-top box itself are included, but with the continuous popularization of an Android television and the continuous improvement of television performance, the hardware capability of an Android television system itself is gradually stronger than the hardware configuration of the IPTV set-top box, and the IPTV function is realized by integrating an application software middleware in the television system, so that the cost of the hardware of the IPTV box itself is removed, which has become an important development direction.
Currently, the mainstream implementation mode of IPTV on set-top box is to bear the content of EPG through a browser, where the EPG implementation language is a WEB language based on HTML + CSS + JavaScript, and meanwhile, by extending a JavaScript object that the WEB itself does not have, interaction on the WEB of the extended object and Native language is opened, to implement functions such as authentication, audio and video playing that the standard WEB does not have.
On the set-top box, the Android system version commonly used is fixed, and the system source codes are customized and maintained by the set-top box, so that the source codes of a system bottom layer browser can be customized on the set-top box to customize the presentation of the EPG content.
However, in a television system, due to the fact that various television brands and television system versions are different, the television brands and television system versions cannot be unified through customizing a system bottom layer source code, the most effective solution is to use a unified API provided by Android for applications to be compatible with Android version differences, and a browser is required to be used on the Android APP to realize the display of WEB EPG content by means of a WebView component interface provided by the Android API.
However, the Android WebView component has the problem that the provided existing interface only supports the extension of a global JavaScript object, and thus does not support the extension of a local JavaScript object, but if the API interface of the extension WebView component supports the global extension, the modification of a java frame module, a JNI module and a Native module of the Android system is involved, which is not sufficient for realizing the compatibility of various differentiated television systems in a unified manner and realizing a unified mechanism.
