Method for developing digital television application based on browser

Abstract

The invention discloses a method for developing digital television application based on a browser. The underlayer operation of DVB application is packaged into javascript objects and functions by a set-top box and then supplies to the browser; the digital television application is manufactured into an HTML page by a front-end application management system, and the HTML page is sent to the browser, wherein the HTML page contains Javascript objects and functions capable of being analyzed and executed by the browser; when a user uses the digital television application, the browser opens the HTML page and executes the Javascript functions; the Javascript functions are translated into the DVB application through underlayer explanation; and the browser integrates the DVB application and the VOD application in the HTML page into one HTML page and displays the HTML page. By adopting the technical scheme of the invention, the DVB application and the VOD application can be combined for use, so that the framework of a television system is more flexible and can be maintained and expanded more simply.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a method for developing digital television applications based on a browser. Background technique [0002] With the development of technology, the digital TV two-way service platform can already bring more and more personalized experiences to users with the support of browsers. However, with the development of two-way services and the improvement of user requirements, traditional digital video broadcasting (Digital Video Broadcasting, DVB) business applications have highlighted the shortcomings of inhumanity.

AI Technical Summary

Problems solved by technology

[0019] 1. The EPG obtained by the set-top box through TS stream parsing of the EIT table can only be provided to its own application, which requires the program upgrade of the set-top box for subsequent expansion and modification

[0020] 2. Since the upgrade of the set-top box is very risky, and the upgrade program is troublesome, frequent upgrades of the set-top box are not allowed

[0022] 4. If the set-top box cannot be upgraded locally, the risk of upgrading the set-top box will increase. If the overall upgrade fails, the set-top box cannot be used

[0023] 5. Affected by the hardware conditions of the set-top box, it cannot provide users with rich personalized services

[0024] 6. Since the loader upgrade program can only be triggered when the device is turned on, each upgrade needs to be turned off and on again, and the user's power on / off is uncontrollable. Most users will not power off for several months, so the upgrade process sometimes Unable to start

[0025] 7. TV users cannot actively initiate personalized services, such as: template replacement function
