Description
Utilize the method for standard TV receiver display webpage and the browser technology field for this method
It is more particularly to a kind of when using standard TV set for browsing webpage the present invention relates to a kind of method that effective display area domain of utilization standard TV receiver browses webpage, the effective display area domain of standard TV receiver is made full use of, a certain particular frame is shown as completely as possible（Frame the method for content), and it is related to the interface method for being used to browse the browser of webpage used in a kind of display web-page approach of the invention.
Background technology
So-called frame, is exactly divided into many regions, each region is a relatively independent region when showing webpage by the window of browser.Table identifier is e.g. used in webpage（For example<table〉）The region that institute's segmentation comes out（On by the content that Web-page segmentation is region, refer to http:The technical documentation of RFC1942, RFC 1866 in //www.w3.org）.In the design of webpage, the tissue to the content of each frame is typically all that the information of different classifications is categorizedly organized in different frame ins.
Method using general television set browsing network information has many kinds.For example directly by webpage according to certain ratio directly all including on the screen of television set；The user surfed the Net using TV will be transmitted under new webpage again either after the server end info web to be accessed user is reorganized, arranged；Also a kind of is exactly to utilize digital image processing techniques in client, and high-resolution Web page image is converted into being adapted to the method for vision signal shown on standard TV receiver to the mode that any part or full figure Jin Hang Shrink for generating original image by local browser are put.
For last this method, refer to the number of patent application of the present inventor is 00105579.8 " using the adaptation method of standard TV set for browsing network image, text and data " patent application.The characteristics of this kind of technology, can be made using standard TV receiver or other types of low resolution monitor come the user of browsing network information, it can be seen that clearly web page contents, while not destroying the personalized style of the original design of webpage and the skill of layout also
Art effect.
In the invention of the invention described above people, it refer on when carrying out any scaling to original image, it needs to be determined that " viewing area " to be dealt with, in its determination principle, it is that whole image is treated as one on the whole, and actually most of webpage present in real world is that its content framing is carried out into tissue.For actually browsing the people of webpage, during browsing network information, the amplification of some part is interested in this part of information because of him by he, and this partial information is actually in some specific frame in.Due in above-mentioned published invention, it is actual to user on television screen it can be seen that " viewing area " determination, the framing information of webpage being made up of multiple frames is not considered, " viewing area " thus so determined, also could not just consider that content of the user actually to which subregion of whole Web page image is interested.
Fig. 4 represents to throw the net page all including the schematic diagram on television screen by one with the above method of the present inventor.The scope that dotted line in Fig. 4 is enclosed is exactly the scope of one of frame.User moves the cursor to the position that arrow in figure is identified, and this position is exactly in the range of that frame that dotted line is identified.Now if the user desired that by webpage amplify so that its a little clearer, " utilizing the adaptation method of standard TV set for browsing network image, text and data " directly as mentioned above is amplified processing to it, then must processing " viewing area " as dotted line is drawn a circle to approve in Fig. 5 scope, the effect that it is obtained after directly handling is as shown in Figure 6, in the present invention as stated above, it is determined that the basic principle of " viewing area " is determined centered on cursor position, according to set scaling.It will be seen that in result at this moment, that frame interested to user（That frame of scope is marked in Fig. 4 with dotted line）Interior information only accounts for the sub-fraction of whole screen, and remainder is not intended to the part browsed, so that the failing of the limited effective display area domain of television set is fully utilized.
On the other hand, ' graph text information on network, such as webpage, there is the form for supporting framing, relative position of the different frame in whole webpage is known.Herein, the boundary information of webpage framing and each frame in whole Web page image is provided by browser.
Object handled by browser is HTML (Hypertext Markup Language) file, and in html format, with framing（Frame function), i.e. when showing webpage, the window of browser is divided into multiple regions, each region is an independent Webpage, so as to constitute multiple frames, by this framing function, the content of webpage can be split, so that there is provided a kind of brand-new method for browsing webpage.（Referring to Internet webpage making guides, People's Telecon Publishing House, 1998,12).If these framing information can be made full use of, more flexibilities can be provided to Web page image processing.
The present inventor's《Browser and the method using the browser display image》（Application number：00123435.8) in invention, browser is divided into web browser module and webpage postprocessor module according to function.Web browser is obtained after information from internet, by output translator, enter the Web page preprocessor, the data exported by webpage preprocessor to browser carry out image real time transfer, then input the picture output device such as standard TV receiver or high-definition television and shown.And the user instruction information inputted from user input, it is also the data processing by webpage preprocessor, and after input converter is changed, input to web browser.The function of web browser module is that HTML language is parsed, and the function of webpage postprocessor module is to carry out image real time transfer to the data that web browser is exported.
When with the webpage with framing structure is shown in standard TV receiver, pass through webpage preprocessor, to any local of the original image that is generated by web browser or full figure is zoomed in and out using framing information so that each frame can be shown as completely as possible on standard TV receiver.
During above-mentioned display, when with the webpage with framing structure is shown in standard TV receiver, pass through webpage preprocessor, to any local of the original image that is generated by browser or full figure is zoomed in and out using framing information so that each frame can be shown as completely as possible on standard TV receiver.This is accomplished by the information that the information of the piece image with multiple frames is converted to the image that can generate each frame.
But, because the data that web browser is exported are that framing information is blended in by one kind
Video flowing together, webpage preprocessor is when handling the data of browser, if using existing data processing method, then None- identified goes out each framing information related to frame structure, so as to when the image real time transfer such as zooming in and out to original image, it is impossible to take into account the characteristics of by the structure of frame so that the image of display only shows a part for several frames, rather than whole images of some frame, the display for making image is not fully effectively.
Have again, when with standard TV set for browsing webpage, user is needed by user input equipments such as keyboard or Genius mouses, information and the various command informations such as the frame browsed are wanted in input, such as user clicks on the position where some framing on screen by using Genius mouse, to represent that user wants to browse the content of the framing.Now the flow of data is, the information that user is inputted by input equipment is transmitted to webpage preprocessor, web browser is transmitted to after input converter, web browser is received after the input information of user, operation to user is reacted, and refresh the output data of browser, webpage preprocessor is given by new data afterwards, and video reception apparatus is transmitted to after the processing of webpage preprocessor.So as to set up corresponding relation between user input equipment and standard TV receiver in keyboard etc..But, because the data of user input are the processing of webpage preprocessor to be first passed through, and between webpage preprocessor and browser in the case where not setting agreement in advance, browser can not receive and recognize these user profile, and webpage preprocessor can not also obtain the information about structure of web page from browser.
The disclosure of invention,
The purpose of the present invention is exactly in order to solve above-mentioned weak point, by it is determined that take into account the situation of frame in webpage when " viewing area ", making " viewing area " as much as possible to include user's content interested.

The present invention utilizes the information of webpage framing, the frame where the information interested to user is judged by current cursor position, so it is determined that can be seen on a television set region when, that frame interested to covering user, the effective display area domain on the fluorescent screen of general television set can be more fully utilized to reach as wide as possible.
On the part related to the structure of the browser of the present invention, it will be specifically described later.
In general, the content of different classifications is located in different frame.It is sometimes interested in some contents as browsing for people, when he using television set to browse info web when, interested region can be moved the cursor to, and the subregion is exaggerated in order to browse, this method is done as follows when user does such operation：
1. the size and the information of position three of cursor in the original image region of processing needed for the boundary position of frame, current webpage preprocessor where obtaining cursor.
2. the border of processing region is determined centered on present cursor position.
3. the border in detection process region whether where the cursor frame border, if its corresponding other border is redefined by new border of the border of place frame if.
4. detecting current border, the frame in where each border is satisfied by being in cursor, or scope determined by current border are a most boundary values of this content frame included in the region repeatedly determined repeatedly.
5. the boundary information of identified process range is passed into webpage preprocessor, it is further processed by it.
6. when including real-time video image stream in the info web of required processing (such as when browsing the website playing news, film in real time）The real-time video image stream viewing area is defined as a special frame, the change of ratio is only done in processing to the frame, the passage of one bypass webpage preprocessor is provided for browser, " viewing area " should write with the position of the video data buffer area of standard TV receiver interface that there is provided the data channel write direct come " special frames " of processing needed for determining directly according in current system determined by.
In above-mentioned steps 2, determine that the method on the border of processing region uses number of patent application for the adaptation method described in 00105579.8.
Fig. 3 corresponds to the schematic diagram of aforesaid operations step 1 one 6.
As described above, the method of the present invention is " viewing area " for determining more to meet user's custom using the information of framing in webpage, it is simultaneously a kind of special frames also by the frame definition with real time video image stream, and offer can bypass the passage of webpage preprocessor, by the data of real time video image stream after transformation of scale, the video data buffer of output is write direct, for this partial data without processing, to mitigate the calculating intensity of webpage preprocessor.Implement bypass processing unit when, can according to " viewing area " facilities, by the data division of the frame in of real time video image stream or all write-in it is defeated
Go out screen buffer, according to the selection of user, according to output screen buffer and the size of the special frames of real time video data, special frames Shrink can also be reset and put ratio, special frames are displayed in full screen.
When the processing region determined by causing due to magnification ratio is limited only to a frame in portion, the content of other frames is not seen on the fluorescent screen of television set then, at this moment on each border of the viewing area of television set, corresponding prompt message is shown, indicates there is the presence of other frames.
When user is moved the cursor in the prompt message of other frames, automatically processing region is switched to other frame locations, if on the tv screen it can be seen that in the case of the marginal information of other frames, region where Genius mouse to be moved to user other frames, and cursor is remote enough apart from the border of frame（On definition remote enough, determined according to actual analysis result）In the range of frame where processing region is switched to cursor by Shi Zidong.
After above-mentioned a few step operations, according still further to " utilizing the adaptation method of standard TV set for browsing network image, text and data ", corresponding original Web page image is handled and is shown on the fluorescent screen of television set.
The effect of the present invention is as shown in Figure 7, according to interested to cursor position determines user the position of frame, according to new " viewing area " can be redefined to the implementation process that is described of the present invention above, in the figure 7, the region that single dotted line is enclosed is " viewing area " determined according to number of patent application for the adaptation method described in 00105579.8, the region that doublet is enclosed is to want " viewing area " that browses with boundary demarcation, the user of frame, and this region will be re-determined according to the method described in the present invention.Fig. 8 is the schematic diagram for being amplified the region that doublet in Fig. 7 is enclosed.It can be seen that the information of frame occupies most of region of television screen where cursor, so as to so handle the purpose for also just having reached and having made full use of television screen to show user's content interested.
It can be seen that there are several arrows lower left corner in Fig. 8, the presence of these arrows is in order to indicate whether also having depositing for other frames around region shown by this current screen
By such prompting, user can easily know the presence of other different information areas when the webpage browsed is being shown by non-full page（Because in general the organizer of webpage is usually that the information of different classifications is organized in different frame ins）.Also allow for being switched fast viewing area simultaneously to other frames, for example, the arrow in different directions is tapped by defining, viewing area can be switched rapidly and gone to other frames.
Fig. 9 is can be by the schematic diagram after displaying ratio when browsing further amplification in the case of being not yet satisfied with when user browses to Fig. 8 display effect.What is required emphasis herein is a bit：The method actual effect that is intended to be merely illustrative of the present of effect shown in above-mentioned and for an example.When actually realizing this method without departing from the spirit of the present invention, specific take the form of allows what is changed, and what is occurred in the figure such as in Fig. 8, Fig. 9 is used to refer to around this current screen whether also prompt message as arrow of presence of other frames etc. can have other forms of expression completely.
In addition, the method for the switching of frame can also be realized with other forms.For example：Prompting for the presence of other frames can also use the appearance anticipated as shown in Figure 10, when the content of a certain frame is only only capable of displaying in the case of due to non-full screen display on television set, if currently from television screen it can be seen that region scope outside also there are other frames in the case of, when user moves the cursor to screen edge the presence of other frames is indicated ejecting a line bar at the edge of screen, the position that the position that the edge strip occurs is to other frames suggested by it are present is related, for example because the left side of in the case of current display " viewing area " has other frames in the case of illustrating in Fig. 10, now user moves the cursor to left side edge and just shows that there are other frames in its left side with a line bar, when the position of cursor is moved to above such edge strip by user and makes the action of percussion, " viewing area " can be automatically switched in the region of that corresponding frame；It is same as Fig. 11 illustrates, because also there is a presence of other frames the top in the region observed by current, thus equally also have when cursor is moved to the top edge of screen the presence of other frames on the upside of automatic spring a line bar display current display area.In addition when the prompt message that the content that other frames are can see on screen is that corresponding frame would not occur.When " sight
Examine region " border and the border of frame be to be in the case of matching; can occur the image of other frame boundaries in viewing area; the switching at this point for frame can exceed cursor movement according to user that " viewing area " is switched into requirement of the corresponding the present embodiment to basic hardware environment immediately after the certain distance of border is as shown in Figure 1; in Fig. 1, shown hardware environment includes：Standard TV receiver 102, control interface device 101, network access equipment 104, central processing unit 105, interface and conversion equipment 106, memory 107 etc..Wherein, control interface device 101 can be Genius mouse, keyboard etc.；Network access equipment 104 can be modem；Central processing unit 105 includes basic interface unit；Interface and conversion equipment can be NTSC/PAL, encoder etc.；Memory 107 has program storage area（Such as ROM, RAM）108th, data storage area 109.And data storage area 1 10 is divided into original graph data storage area 1 10 and output data storage area 111.
