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 present invention proposes a dual-mode data receiving and accessing method based on an embedded browser, which is used to support the embedded browser to receive broadcast data and Internet data through CABLE and IP channel respectively, including: step 101) data for the IP channel , the embedded browser uses the standard HTTP protocol to transmit and receive; Step 102) For the data of the CABLE channel, the embedded browser uses the custom data communication protocol "cable protocol" to receive broadcast data, and when downloading the broadcast data When there is a URL request, the application layer outside the browser kernel performs broadcast data transmission processing, and after processing the download and storage of the data, the broadcast data The storage address, that is, the new URL address, is returned to the browser kernel for use. The invention places the processing of broadcast data in the application layer instead of in the browser kernel, so that the structure is clear, the application expansion is strong, and the development cycle is accelerated.

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. [000...
