As mentioned above, method of the present invention is to utilize the information of dividing frame in the webpage to determine more to meet " viewing area " of user's custom, the frame definition that also will have real time video image stream simultaneously is a kind of special frames, and provide can bypass webpage preprocessor passage, after the data process transformation of scale with real time video image stream, the video data buffer that writes direct and export is not handled for this part data, to alleviate the calculating strength of webpage preprocessor.During specific implementation bypass processing unit, can be according to the situation that is provided with of " viewing area ", with the data division in the frame of real time video image stream or all write the output video buffering area, also can be according to user's selection, size according to the special frames of output video buffering area and real time video data, reset the scaling of special frames, make the special frames full screen display.
When the reason owing to magnification ratio causes determined processing region only to be confined to frame inside, then on the phosphor screen of television set, cannot see the content of other frame, at this moment on each border of the viewing area of television set, show corresponding prompt information, indication has the existence of other frame.
When the user moves to cursor on the information of other frame, automatically processing region is switched to other frame in-scope, if under the situation of the marginal information that can see other frame on the video screen, Genius mouse is moved to the zone at other frame place as the user, and cursor (about enough far away definition, according to the analysis result of reality determines) enough far that apart from the border of frame time switches to processing region in the scope of cursor place frame automatically.
After above-mentioned a few step operations,, corresponding original Web page image is handled and is shown on the fluorescent screen of television set again according to " utilizing the adaptation method of standard TV set for browsing network image, text and data ".
Effect of the present invention as shown in Figure 7, according to the cursor position determine the user frame interested the position, can redefine new " viewing area " according to top to the implementation procedure that the present invention narrated, in Fig. 7, the zone that single dotted line is enclosed is that 00105579.8 described adaptation method is determined " viewing area " according to number of patent application, the zone that doublet enclosed be with the boundary demarcation of frame, the user wants " viewing area " browsed, this zone will be redefined according to the method described in the present invention.Fig. 8 is the schematic diagram that the zone that doublet enclosed among Fig. 7 is amplified.The information of cursor place frame has occupied most of zone of television screen as can be seen, has also just reached the purpose that makes full use of the more interested content of television screen explicit user thereby handle like this.
Can see that in Fig. 8 there are several arrows the lower left corner, the existence of these several arrows is the existence that whether also have other frame in order to indicate around current this shown zone of screen, by such prompting, the user when being shown by non-full page, can know the existing of other different information areas (because generally speaking the organizer of webpage generally is that information organization with the difference classification is in different frames) at the webpage of being browsed easily.Simultaneously also be convenient to switch fast the viewing area to other frame, for example knock the arrow of different directions, can switch the viewing area rapidly and go to other frame by definition.
Fig. 9 be the user when browsing to the schematic diagram after can the displaying ratio when browsing under the also unsatisfied situation of the display effect of Fig. 8 further amplifying.What here require emphasis a bit is: the effect shown in above-mentioned only be for method actual effect of the present invention is described for an example.When realizing this method, reality needs only without prejudice to spirit of the present invention, concrete taking the form of allows vicissitudinously, and what for example occur in figure such as Fig. 8, Fig. 9 is used to refer to the such informations such as arrow that whether also have the existence of other frame around current this screen other the form of expression can be arranged fully.
In addition, the method for the switching of frame also can realize with other form.For example: also can be with the appearance of meaning as shown in Figure 10 for the prompting of the existence of other frame, in the time of on owing to television set under the situation of non-full screen display, only showing the content of a certain frame, if under the situation of the frame that also has other outside the scope in the current zone that can see from the television screen, when moving to screen edge with cursor, the user ejects the existence that an edge strip is indicated other frame at edge at screen, the position that this edge strip occurs is relevant with the position of its other suggested frame existence, example as shown in Figure 10 in the situation of meaning since under the situation of current demonstration the left side of " viewing area " have other frame, the user moved to left side edge with cursor and just showed that with an edge strip there is other frame in its left side this moment, when the user position of cursor is moved to such edge strip above and when making the action of knocking " viewing area " can automatically switch in the zone of that frame accordingly; Equally as schematically shown in Figure 11, because also there is the existence of other frame the top in current observed zone, thereby when cursor moves to the edge, top of screen, equally also ejects an edge strip automatically and show that the upside of current viewing area has the existence of other frame.The content that ought can see other frame in addition on screen is that the information of corresponding that frame just can not occur.When the border of " viewing area " and the border of frame are to be under the situation about matching, the image that can occur other frame boundaries in the viewing area switches to " viewing area " in the corresponding frame after can cursor being moved beyond the border certain distance according to the user for the switching of frame this moment immediately.
