Problems solved by technology

However, in order to fully realize the support for the data broadcasting protocol inside the embedded browser, it is necessary to add a data broadcasting protocol module inside the browser. In addition to the long development cycle, it will also destroy the original independence of the browser. In addition, if the front-end The various definition conditions and standards of the system are constantly changing, and the browser needs to be updated repeatedly, which is inefficient

Embodiment

[0054] (1) For example, the user clicks a hyperlink in an Internet web page. The URL of this hyperlink is cable: / / 660 / cover.html. This URL indicates that it is a broadcast data. The following describes in detail how the embedded browser requests A complete step from data to reception and access.

[0055] Step 1: The browser passes the URL address to the application layer through the callback interface registered by the application layer. Go to step 2.

[0056] Step 2: The application layer obtains the resource identifier cable: / / 660 / cover.html, analyzes that the syntax of the resource identifier conforms to the cable protocol, starts the DSM-CC protocol to download data, and proceeds to step 3.

[0057] Step 3: Download the data through the data broadcast channel and store it in buffer1, and then store buffer1 in the file / tmp / 660 / cover.html. Go to step 4.

[0058] Step 4: The callback interface re-registered by the application layer returns the actual data path / tmp / 660 / co...

Abstract

The invention proposes a dual-mode data reception and access method based on an embedded browser and the method is used for supporting the embedded browser to receive broadcast data and internet data through a CABLE channel and an IP channel respectively. The method includes the following steps: step 101): for data of the IP channel, the embedded browser adopts a standard HTTP protocol to carry out transmission and reception; step 102) for data of the CABLE channel, the embedded browser adopts a user-defined data communication protocol 'cable protocol' to carry out reception of the broadcast data and adopts an interface callback method when downloading the broadcast data. The interface callback method is specifically as follows: when a URL request exists, transmission processing of the broadcast data is carried out on an application layer outside an inner core of the browser; after downloading storage of the data is processed, a storage address of the broadcast data, that is, a new URL address, is returned to the inner core of the browser for use. In the dual-mode data reception and access method based on the embedded browser, processing of the broadcast data is carried out on the application layer instead of the inner core of the browser so that the structure is clear, the application extensibility is high and the development cycle is speeded up.

Description

technical field [0001] The present invention relates to the technical field of data broadcasting and embedded browser data receiving and accessing technical field, in particular, the present invention relates to a method for receiving and accessing Internet data and data broadcasting data based on embedded browser. Background technique [0002] After digitalization of analog TV, in addition to transmitting traditional audio and video programs, other data can also be transmitted to realize data value-added services, among which data broadcasting is the basic platform of digital TV value-added services. [0003] Data broadcasting refers to the non-audio and video services transmitted by the digital TV broadcasting system, using the data expansion function in the MPEG-II standard to carry out some value-added services, such as stocks, weather forecasts, news, classified advertisements, life information, distance education, TV Games, email, SMS services and applications.
