Embodiment
Fig. 1 of the specific embodiment of the present invention such as accompanying drawing-shown in Figure 6 hereinafter is further detailed embodiments of the present invention with reference to the accompanying drawings.
Whole implementation mode of the present invention as shown in Figure 1, wherein, regular website maker 2, condensing encoder 3, content manager 6 and content manager 7 four parts are for the present invention relates to content, all the other four parts are for adopting existing techniques in realizing, therefore do not make related description.
With reference to Fig. 1, digital broadcast network station dispensing device of the present invention is comprised of website making system, regular website maker, condensing encoder and digital broadcasting broadcast system four parts.
See figures.1.and.2, the major function of regular website maker 2 is to generate the webpage that meets digital broadcast network station design and making of the webpage standard of the present invention.Concrete steps are: at first from website making system 1, read the webpage raw information that to broadcast, make, the automatic generating standard webpage of digital broadcast network station design and making of the webpage standard according to the present invention, in generative process, when finding webpage raw information and norm conflict, will point out the website making personnel to make amendment.These conflicts comprise that the web displaying size goes beyond the scope, the web storage volume is excessive, violate webpage naming rule etc.After this, with the standard web page files that generates, store by relevant storage directory structure (Fig. 7, Fig. 8) in the digital broadcast network station webpage making standard of the present invention.After the generation of all webpages of finishing this website issue, condensing encoder 3 will be notified and activate to regular website maker 2.
With reference to Fig. 1 and Fig. 3, the major function of condensing encoder 3 has two, and the one, all webpages that broadcast are carried out compressed encoding, the 2nd, the web data behind the compressed encoding is sent to digital broadcasting broadcast system 4.Concrete steps are: at first read the web site contents that will broadcast from regular website maker 2, then, in order to reduce the bandwidth occupancy that is broadcasted data, the web site contents that will broadcast compresses; Not have on the receiver of conditional receiving device in order solving, to realize the safeguard protection of web page contents, the web site contents after will compressing again carries out security code, and is last, and the web site contents behind the security code is sent to digital broadcasting broadcast system 4.
With reference to Fig. 1, Fig. 4, digital broadcast network station receiving system of the present invention is comprised of digital broadcast receiving system, content manager, content server and web browser four parts.
Wherein, content manager is comprised of three parts, that is:
(1) the data receiver unit of Content Management is finished from digital broadcast receiving system and is received web data;
(2) the file process unit of Content Management is finished the web data that receives is decompressed, separates coding;
(3) memory management unit of Content Management is finished and the web data behind the uncompressed encoding is carried out the memory management functions such as content choice, memory space release, expired content deletion.
Configuration and the workflow of above-mentioned three unit are described below:
With reference to Fig. 4, Fig. 5, content manager data receiver unit 6-1, at first automaticallying switch from data broadcast receiver system receives frequency (Fig. 5 S3-1), receives object data from a plurality of frequencies.The switching that receives frequency does not need user intervention.The data age that the design of handover mechanism has taken into full account application program corresponding to each frequency requires and the master data unit-sized, can guarantee that the data of each frequency are in time received, thereby satisfies the demand data of application program corresponding to each frequency.Then to the data that receive disappear heavily (Fig. 5 S3-3).Because the data broadcast end constantly repeats to send object data, so, after receiving terminal is received object data, judge whether it is new.The data of the object of the same name (if any) of the object data newly received and receiving terminal storage are compared, if the different file of just replacing original storage has so just reduced the write operation number of times to flash memory most possibly.
With reference to Fig. 4, Fig. 5, content manager file process unit 6-2 at first carries out safe decoding (Fig. 5 S3-5) to the web page files that receives, and (Fig. 5 S3-5) then decompresses.
With reference to Fig. 4, Fig. 5, content manager memory management unit 6-3 mainly is achieved as follows function:
(1) web site contents standard bibliographic structure structure (Fig. 5 S3-9, S3-11, S3-13).Guarantee that the chained address in the webpage is effective, receiving terminal is the creating website bibliographic structure correctly, and obj ect file is stored in the correct catalogue.Receiving terminal is determined the bibliographic structure of website according to the contained directory information of object oriented.In addition, bibliographic structure is arranged to web object file management (webpage of the same name when web page contents upgrades is replaced, and web page files is superseded etc.) convenience is provided.
Web site contents top-level director structure on the terminal as shown in Figure 7.Among the figure, deposit the curing content (content under the BuiltIn/ catalogue is that all terminal types are shared, and the content under the BuiltInT01/ catalogue is the terminal of T01 for type only) of website under BuiltIn/ and the BuiltInT01/ catalogue.The content of solidifying the webpage under the catalogue seldom becomes, and mostly is frame page, navigation page and permanently effective webpage, so can in advance these contents be write the curing catalogue before terminal is dispatched from the factory.The content of solidifying under the catalogue can be broadcasted new edition content replacement or increase by initiator.Deposit the content of frequent renewal (replace, increase or deletion) under the Variable/ catalogue, be generally concrete/detailed content page or leaf.
(2) content choice (Fig. 5 S3-7).Broadcast Website is supported the terminal of multiple different screen size and resolution simultaneously.Initiator sends many cover template/frame page files simultaneously, every cover template/frame page file is for a kind of terminal, receiving terminal abandons the template/frame page that belongs to other terminal type simultaneously according to respective directories template/frame page under one's name that this terminal type is selected and storing received arrives.The website top-level director structure of initiator broadcasting as shown in Figure 8.Type be on the terminal of T01 the directory web site structure then as shown in Figure 7.Can find out, type is to only have BuiltInT01/ on the terminal of T01 this solidifies catalogue (except the curing catalogue BuiltIn/ and variable content catalogue Variable/ that each terminal type is shared), leaves template/frame page of using on this terminal in.
(3) memory space discharges (Fig. 5 S3-15, S3-17).Flash memory storage limited space on the terminal, and the content of broadcasting can be constantly updated and increase, so the inadequate situation in space can occur.Remaining space is less than when specifying size, just need to according to certain rules selection (as the last access time of file early, or the document creation time early etc.) and delete some web objects, with the release memory space.A webpage may be made of a plurality of parts, and such as framework and parts, webpage and embedded picture thereof etc., deletion action " top-down " is carried out, and avoids leaving over imperfect webpage.
(4) expired content deletion, some web object has been set the term of validity by the web content management person, and the term of validity one be after namely should not being seen by the user again, thus can not stay in the storage system of terminal, therefore will delete.
(5) data receiver situation report (Fig. 5 S3-19 ,-23), in order to save broadcast bandwidth, the display layout such as template/frame page and style information are only broadcasted finite time, but not always broadcasting in its life cycle.So certain terminal might not receive template/frame page because do not start shooting during the broadcasting, causes web site contents normally not present.This situation need to be notified the user the very first time (when the user starts shooting for the first time after the situation generation).
Initiator sends the key object information table always, wherein list also in life cycle, but the template/frame page of having broken for information about, and receiving terminal shows accordingly to judge whether that the latest edition of object or object does not receive.
(6) desktop important news generates, and when the web page files content update under the assigned catalogue or newly-increased web page files, searches for the web page files under this catalogue, automatically generates terminal desktop important news message file, hands over the desktop management program to present to the user.Desktop important news information comprises important news title, date and chained address (pointing to the important news particular content).The important news clauses and subclauses are pressed treaty rule (press the filename under the assigned catalogue, or by the date that extracts) ordering from file.
With reference to Fig. 1, Fig. 4 and Fig. 6, according to the present invention, content server (Fig. 4 7-1) receives the web page browsing request that browser is sent, and gives browser with response.Be implemented as follows function:
(1) request analysis (Fig. 6 S4-1, S4-3) is waited for request, receives the request string and will ask string to resolve to path (containing object name) and parameter (can be a plurality of) two large divisions.
(2) request response (Fig. 6 S4-7, S4-9, S4-11), minute following two kinds of situations:
● ask concrete webpage, take out corresponding web object Data Concurrent from storage system and give browser.
● request dynamic generates the navigation page of the webpage under the assigned catalogue, and the template based on appointment dynamically generates the navigation page Data Concurrent to browser automatically.If entry number is too many, not in the entry number restriction of template regulation, then in the navigation page that generates, automatically implant " prevpage ", " the next page " button and corresponding chained address (to indicate dynamic generation " prevpage " or " the next page ") thereof.Clauses and subclauses listed in the navigation page are by the date ordering of extracting from its corresponding web page files.
