Embodiment
Describe the present invention below with reference to the accompanying drawings in detail.
With reference to Fig. 1, the page returning method that is used for electronic program list navigation according to the present invention may further comprise the steps:
Step S102 is provided for the storehouse of memory page parameter.
Step S104, when visiting the homepage of electronic program list navigation, the parameter of homepage is pressed into storehouse.
Step S106, when the link of visit on the current page, enter the link corresponding page after, the parameter of the page that is entered is pressed into storehouse.
Preferably, when the parameter of the page that is entered will be pressed into storehouse, judge whether the parameter of the page entered exists in storehouse,, then all elements on the location ejected that the parameter with the page that entered is pressed into storehouse again if exist.
Step S108, when when current page has been selected return, at first the stack top element with current stack ejects, return up-to-date stack top element then, link according to the stack top element generation back page that is returned enters the page that is returned, and is back to step S106.
Preferably, enter the page that is returned after, the parameter of the page that is entered is not pressed into storehouse.Return sign by setting, distinguish the page that enters link and still enter the page that returns,, then carry out stack-incoming operation,, then do not carry out stack-incoming operation if enter the page that returns if enter the page of link.
Further, by set-top box visit the homepage of electronic program list navigation, on the current page link and select return at current page.
Further, the parameter of homepage is a bottommost element, when only having the parameter of homepage in the storehouse, goes out stack operation and includes only the parameter that returns to the homepage.
Further, the link between the page of electronic program list navigation is a tree structure.
Further, on the page, be provided with and return label, be used to carry out the selection of return.
Page parameter can comprise the page access path.
Can usually trigger stack-incoming operation and go out stack operation by page Tag unit.
The present invention relates to the IPTV technology, particularly EPG page rollback technology.
The page returns the reason that need realize on the EPG backstage be that the embedded browser of set-top box does not offer the rollback that the user carries out the page as the method for the menu of IE or toolbar and so on, the user is when page migration like this, can only advance toward the direction, and the rollback of the page need be controlled by the EPG backstage.
Be directed to the characteristics of the EPG page, the linking relationship between the user to access pages can be abstracted into tree structure.As shown in Figure 2, what the user at first visited is the EPG homepage, it is the root node of tree structure, the link down visit in layer that provides by homepage then, any one other node from certain node visit tree if desired, this node provides the direct link of this node, or return back to higher level from this node, enters into destination node from that place then.If having tabulation on the EPG page shows, may relate to the situation of page turning, but no matter how many pages or leaves the user has turned over, it is to rest on the node of current page correspondence all the time, this situation correspondence be the circular route of Far Left second-to-last node among Fig. 2, if this time, the user carried out rollback, should be to get back to a last node that enters this node from logic, rather than get back on that node of user's page turning just now, so have this link of page turning for the page, on Fig. 2, just be abstracted into a link pointing to oneself.May exist a plurality of places to enter for some pages in addition, when this page returns, should be to get back to that page that enters it so.
According to above-mentioned analysis, in applied environment based on the set-top box accessed web page, the invention provides the implementation method that a kind of page returns, the core of this method is to realize a kind of data structure that is similar to storehouse on the server of EPG, it is a kind of special storehouse, and its operating procedure is as follows:
1, the homepage of set-top box visit EPG, the parameter of homepage is stacked, and homepage is a bottommost element, when only having this element in the stack, goes out stack operation and just returns this element, no longer does other operation;
2, the link on the set-top box visit homepage, enter this link corresponding page after, the parameter of this page is stacked;
3, according to step 2, the page of visit constantly is pressed in the storehouse, in pop down, need do following judgement: judge at first whether the current page of pop down of wanting exists in storehouse, if exist storehouse so with this position and on all records all from storehouse, eject, then with current page pop down;
If 4 have selected return the current page user, EPG at first ejects the stack top element of current stack so, returns the element of up-to-date stack top then; EPG generates the link of back page according to the element that returns.
Adopt above-mentioned logic to realize the context preservation in EPG page access path, have following characteristics: the link between the EPG page is a kind of tree structure, but user's access path can be regarded as linear structure, this structure is a kind of special stack architecture, why adopt this special stack architecture, the stack top element that is storehouse on the one hand is could produce when the user carries out page migration, but the element that produces does not but belong to the element in the user access path, and it only is only the active data element when the user further operates.Judge it is continuous increase for the content that exists in the push operation process, needing, also guarantee to return the correctness of logic simultaneously for fear of storehouse length according to storehouse.
What the present invention at first needed to realize is above-mentioned stack architecture, according to the described page link migration models of Fig. 2, we can think that it is simple tree structure, visit for tree structure, we are that the principle according to depth-first travels through node on the whole tree, support that so the needed secondary data structure of this visit is exactly to need the access path that storehouse comes recording user.
The operation that this storehouse need provide mainly contains two: stacked and pop, Fig. 3 has described the precedence diagram of operation storehouse, but these two operations and the corresponding operation logic of standard storehouse are had any different:
For going out stack operation, we know when entering certain page, at first we must be pressed into storehouse with the required parameter of this page, but when when this page returns, need to carry out one and go out stack operation, this operation should be at first to eject stack top element to abandon, then obtaining current stack top element, as the return value that goes out stack operation.
For stack-incoming operation, at first we need judge whether exist in the stack and the current element that will go into the stack element like-identified, if exist, represent that current stack-incoming operation is to return from a very dark level, so in fact, element all should be abandoned the stack on the element of this existence, and then this element is stacked.So just avoid the unconfined growth of element in the stack.
After having realized above-mentioned stack architecture, what next need to consider is exactly the problem that how combines with this technical characterstic of Web, at first we need consider such problem, when we will turn back to the last page, need to carry out one and go out stack operation, simultaneously when entering that page that returns, need to carry out a stack-incoming operation again, but the data of this action need are exactly the element of current stack top in fact, so when the page returns, stack-incoming operation is unnecessary, but EPG can not distinguish this stack-incoming operation when carrying out stack-incoming operation be normal stack-incoming operation or owing to returning the stack-incoming operation that causes, so EPG is when realization is returned, a sign need be set distinguish this situation, in order not influence the content in the original storehouse, this sign can transmit by the Session mechanism that Web server is supported.
On the EPG page, need to trigger two operations of storehouse, one is the page parameter push operation, and another one is exactly that page parameter goes out stack operation, and these operations can be packaged into the page Tag element of standard.
Fig. 3 has described the flow process that page pop down and the page are popped:
201 clients are initiated page request to the EPG server;
202 EPG servers obtain required parameter, and the object that generates in the storehouse is preserved these parameters;
203 EPG servers are pressed into this object in the storehouse;
204 storehouses are pressed into storehouse according to the stacked rule of foregoing description with this object;
205 EPG server response page requests;
206 clients are initiated the page to the EPG server and are returned request;
207 EPG servers are from the storehouse stack top element of being hit by a bullet out;
208 EPG servers are according to the request of ejecting a target pages of stack top element structure;
209 EPG servers are issued client with the request of target pages and are redirected.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
