Method and apparatus for implementing digital broadcast network station based on file type transmission mode

Abstract

The invention discloses a method for realizing a digital broadcast website, which comprises the following steps: based on a strategy of first storing and then browsing, the content of the broadcast website is made, sent, received and displayed; a webpage to be broadcast is generated and checked whether the webpage meets the standard; the webpage to be broadcast is subjected to compression and security coding and sent to a digital play system; broadcast webpages are alternately downloaded from a plurality of frequency points of the digital broadcast receiving system; the received webpage data is subjected to decompression and decoding; the decompressed and decoded webpage data is subjected to content selection, the release of storage space, the deletion of overdue content and other operations; and a webpage browsing request sent by a browser is received, corresponding response is given according to the request type. The result is as follows: when the broadcast website is browsed in a digital broadcast receiver, data is locally obtained only from the receiver, thereby separating the processes of browsing webpage data and receiving the webpage data in order that the browsing of the webpage has no relation with the quality of a broadcast signal where the receiver is positioned at that time.

Description

technical field [0001] The invention relates to a method for realizing a digital broadcasting website and related devices. The implementation method and related devices adopt the file-type transmission method, that is, the content service strategy of not browsing when receiving, and browsing after storage, and can realize interactive content browsing of digital broadcasting websites on the digital broadcasting receiver in the one-way digital broadcasting application environment and quasi-real-time content updates. The present invention can be applied to any digital broadcasting (wired or wireless digital broadcasting) field. Background technique [0002] Compared with the analog broadcasting technology, the digital broadcasting technology enables users of broadcasting receivers to obtain higher-quality broadcasting information services because the information it broadcasts is digitally coded. Digital broadcasting technology, in addition to broadcasting digital video and au...

Problems solved by technology

[0010] (1) Ignoring the positive role that the local storage capability of the receiver can play in the application of digital broadcasting websites, so that re-browsing of the same content requires re-downloading

In addition, all style information and fixed content of digital broadcasting websites need to occupy valuable digital broadcasting bandwidth for broadcasting;

[0011] (2) When the receiver cannot receive the digital broadcast signal, it cannot browse the content of the website, no matter whether it has had the opportunity to receive the content of the webpage to be browsed before;

[0012] (3) The response speed and quality of web browsing are highly related to factors such as the digital broadcasting signal quality at the location of the receiver and the broadcasting frequency (broadcasting times per unit time) of the web page data being browsed, resulting in a negative quality of web browsing service. Uncertainty;

[0013] (4) In the case of using multiple frequency points to broadcast digital broadcasting websites, end users need to select different channels to browse the content of the corresponding broadcasting website, which brings unnecessary troubles to users;

[0014] (5) For receivers without conditional access devices, there is no corresponding mechanism to protect the content of broadcast websites;

[0015] Due to the above-mentioned problems that have brought many restrictions to the actual application capabilities of digital broadcasting websites, such as the display style of the website, the scale of the website, and the ability to publish advertisements on the website are all restricted, so that some important Internet website functions are only available on digital broadcasting websites. Theoretical significance, but no practical application value at all
