Embodiment
The invention discloses a kind of method and system that TV overscanning parameter is set, thus overscanning parameter setting instruction can be received at every turn, only the overscanning parameter of the HDMI exporting current shown program video is arranged, simplify user operation.
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail.
Embodiment one
Fig. 2 is a kind of embodiment of the method one flow chart arranging TV overscanning parameter of the present invention, and described method comprises:
Step 201: store the display tables of data arranged respectively to each HDMI, the display tables of data of each HDMI comprises the former overscanning parameter corresponding with it.
Each television set is configured with multiple HDMI, arranges separately a display tables of data to each interface.The former overscanning parameter corresponding with it is had in the display tables of data of each HDMI.Time initial, arrange identical former overscanning parameter can to each HDMI, generally, the former overscanning parameter of each HDMI is 0, namely point-to-point.Point-to-point (DotbyDot), refers to that each pixel of liquid crystal screen display is corresponding with the pixel of shown image.The most important condition of point-to-point display is the resolution that the physical resolution of liquid crystal display screen equals that (or being greater than) is shown image, just likely more correspondingly with point shows, and ability all risk insurance really reproduces the original image of playback equipment output.Certainly, different former overscanning parameters is set can also to each HDMI, specifically arranges according to actual needs, specifically do not limit here.
Each former overscanning parameter is only applicable to and a HDMI corresponding to the display tables of data at its place, has nothing to do with other HDMI.Independent of one another between the display tables of data of each HDMI, also independent of one another between its former overscanning parameter.Former overscanning parameter in the display tables of data of a HDMI changes, and can not affect the former overscanning parameter of other HDMI.Conventional overscanning parameter is 0 (point-to-point), 5%, 10% etc.,
Step 202: the overscanning parameter setting instruction receiving the HDMI to the current shown program video of output that user sends.
When supposing initial, the former overscanning parameter in the display tables of data of each HDMI is 0 (point-to-point).User watches the program video exported by HDMI 1, finds that the program exported due to HDMI 1 is transcribed, and there is the phenomenon of fringing, edge point at program video edge.Now, user needs the former overscanning parameter adjusting HDMI 1, by the Nonlinear magnify exported from HDMI 1, in order to eliminate the phenomenon of program video edge bands, edge point.User sends overscanning parameter setting instruction, and described overscanning parameter setting instruction carries the new overscanning parameter that user will be arranged the HDMI exporting current shown program video.
The described overscanning parameter setting instruction receiving the HDMI to the current shown program video of output of user's transmission has two kinds of possible implementations:
The first possible implementation, user sends overscanning parameter setting instruction by remote controller:
Receive the overscanning parameter setting instruction of the HDMI to the current shown program video of output that user is sent by remote controller.
The implementation that the second is possible, user sends overscanning parameter setting instruction by television operation panel:
Receive the overscanning parameter setting instruction of the HDMI to the current shown program video of output that user is sent by television operation panel.
Above-mentioned two kinds of implementations, the first implementation arranges the selection key sending overscanning parameter setting instruction on a remote control, and the second implementation is the selection key arranging overscanning parameter setting instruction on television operation panel.In actual product, remote controller and television operation panel all can be provided with overscanning parameter setting instruction selection key, user can adopt any one to send the mode of overscanning parameter setting instruction by unrestricted choice.
Step 203: resolve new overscanning parameter entrained in described overscanning parameter setting instruction.
When receiving overscanning parameter setting instruction, resolve the new overscanning parameter in described overscanning parameter setting instruction, described new overscanning parameter is the overscanning parameter that user resets to the HDMI exporting current shown program video.If former overscanning parameter is 0 (point-to-point) when described HDMI is initial, then user is the value different from former overscanning parameter to the new overscanning parameter set by described HDMI.It is 5% or 10% that user can arrange new overscanning parameter, or other numerical value.Described new overscanning parameter, only to the HDMI exporting current shown program video, can not affect the program video of other HDMI output.
Step 204: utilize the program video that HDMI described in described new overscanning parameter adjustment exports.
By HDMI described in new overscanning parameter configuration, the program video that adjustment HDMI exports, namely amplifies the image that described HDMI exports, thus eliminates the phenomenon having fringing, edge point of program video.Such as: described HDMI former overscanning parameter is 0 (point-to-point), and new overscanning parameter is 5%, then the program video that HDMI described in new overscanning parameter adjustment exports is adopted.
Step 205: replace the former overscanning parameter in the display tables of data of described HDMI by described new overscanning parameter.
The former overscanning parameter in the display tables of data of the HDMI exporting current shown program video is replaced by new overscanning parameter.After receiving the overscanning parameter setting instruction of user's transmission, resolve the new overscanning parameter in described overscanning parameter setting instruction, replace the former overscanning parameter of described HDMI by new overscanning parameter.Because the display tables of data of each HDMI is independent of one another, therefore, former overscanning parameter in the display tables of data of described HDMI replaces to new overscanning parameter, the former overscanning parameter in the display tables of data of other HDMI can not be affected, i.e. the former overscanning parameter constant of other HDMI.When redirect receives the program video of other HDMI output, still export the program video after with former overscanning parameter configuration.And when recalling to the HDMI exporting current shown program video again, owing to being new overscanning parameter in the display tables of data of described HDMI, then described HDMI then configures the program video that described new overscanning parameter display exports.Certainly, if user is still unsatisfied with the program video that described HDMI exports, then can returns step 202 and send an overscanning parameter setting instruction again.
Illustrate, suppose that exporting current shown program video is HDMI 1, when user finds the problem that program video has fringing, edge is put that HDMI 1 exports, send the overscanning parameter setting instruction of adjustment HDMI 1 overscanning parameter, described overscanning parameter setting instruction carries new sweep parameter.Due to generally, time initial, the former overscanning parameter of each HDMI is 0, supposes that to the new overscanning parameter of the setting of HDMI 1 be 5%.With the program video that HDMI described in new overscanning parameter adjustment exports, and replace the former overscanning parameter in the display tables of data of HDMI 1 by new overscanning parameter.When jumping to other HDMI, because the former overscanning parameter in the display tables of data of other HDMI does not change, other HDMI still configure former overscanning parameter 0 (point-to-point) and export program video.When HDMI 1 is returned in redirect to user again, owing to being new overscanning parameter in the display tables of data of HDMI 1, then the new overscanning parameter 5% of HDMI 1 configuration exports program video.
As can be seen here, adopt a kind of method that TV overscanning parameter is set provided by the present invention, receive the overscanning parameter setting instruction of the HDMI to the current shown program video of output that user sends, only can change the former overscanning parameter of the HDMI exporting current shown program video, can not have an impact to the former overscanning parameter of other HDMI.
And when adopting in prior art the method arranging overscanning parameter, because overscanning parameter is a global value, all HDMI all adopt a unique overscanning parameter.When user watches the problem that program video finds that there is fringing, edge is put of HDMI 1 output, heavily overscanning parameter is set to 5% by 0.When then user jumps to other HDMI, the program video that other HDMI export also adopts the overscanning parameter of 5%, and the program video that now other HDMI can be caused to export is imperfect, impact viewing.Now, user needs overscanning parameter to adjust back 0 by 5%.But, when the TV programme of HDMI 1 output is watched in redirect to user again, now HDMI 1 adopts the program video that former overscanning parameter 0 exports, and there will be again the problem of fringing, edge point, user must readjust overscanning parameter, and operating process is complicated.Adopt the method that TV overscanning parameter is set provided by the present invention only can adjust the overscanning parameter of the HDMI of the current shown program video of output, can not have an impact to the overscanning parameter of other HDMI, simplify user operation.
Here it should be noted that, overscanning parameter 0 of the present invention and overscanning parameter 5% are only conveniently be described, and are not limited in above-mentioned two kinds of overscanning parameters, can also arrange other overscanning parameters.
Overscanning parameter in Central Plains of the present invention is a relative concept, and when first time arranges the overscanning parameter of TV, former overscanning parameter is acquiescence overscanning parameter.When adjusting overscanning parameter each time, during front once adjustment overscanning parameter, the overscanning parameter of the described HDMI after upgrading in display properties table is former overscanning parameter later.That is, described former overscanning parameter is before adjustment overscanning parameter, the overscanning parameter stored in described display properties table.
In a specific embodiment, described method also comprises:
The overscanning default value receiving the described HDMI that user sends recovers instruction;
Utilize the program video that HDMI described in the acquiescence overscanning parameter display corresponding to described HDMI exports;
Described acquiescence overscanning parameter is utilized to replace new overscanning parameter in the display properties table of described HDMI.
What HDMI exported has the TV programme of the problem of fringing, edge point to finish, when starting the TV programme playing the problem that other do not have fringing, edge is put that described HDMI exports, owing to changing the overscanning parameter of described HDMI, the program video of the TV programme of current broadcasting can be caused imperfect, need the acquiescence overscanning parameter recovering described HDMI.The overscanning default value that user sends described HDMI by the operation control panel on remote controller or television set recovers instruction, described acquiescence overscanning parameter is utilized to replace new overscanning parameter in the display properties table of described HDMI, making TV when playing the TV programme of the problem that other do not have fringing, edge is put that described HDMI exports, making the program video of TV programme complete.
In another specific embodiment, described method comprises:
Receive TV out code;
Obtain the acquiescence overscanning parameter corresponding to described HDMI;
Described acquiescence overscanning parameter is utilized to replace new overscanning parameter in the display properties table of described HDMI.
Program video due to the TV programme of described HDMI output of televising has the probability of the problem of fringing, edge point less, the program video of most of TV programme that HDMI exports all does not have the problem of fringing, edge point, after user's closing television a period of time, turn on TV again, generally, the program video of the TV programme of HDMI output does not have the problem of fringing, edge point.Due to store in display properties table be according to have fringing, edge point problem program video change after new overscanning parameter, in order to make user's closing television a period of time open again television-viewing do not have fringing, edge point problem TV programme time, program video keeps complete, when user sends closing television instruction, obtain the acquiescence overscanning parameter of described HDMI, the new overscanning parameter in the display properties table utilizing described acquiescence overscanning parameter to replace corresponding to described HDMI.Like this, after user's closing television a period of time, then when turning on TV, due to the acquiescence overscanning parameter stored in the display properties table of described HDMI, utilize the TV programme that HDMI described in described acquiescence overscanning parameter display exports.
In another specific embodiment, described method also comprises:
Whether the TV programme of monitoring the output of described HDMI changes;
When the TV programme that described HDMI exports changes, obtain the acquiescence overscanning parameter that described HDMI is corresponding;
Utilize the program of HDMI described in the acquiescence overscanning parameter display corresponding to described HDMI;
Described acquiescence overscanning parameter is utilized to replace new overscanning parameter in the display properties table of described HDMI.
Generally, the program video of the TV programme that described HDMI of televising exports has the problem of fringing, edge point little, when the problem that program video has fringing, edge is put of the TV programme that a HDMI exports, in order to eliminate fringing, the edge point problem of the program video of described TV programme, have adjusted the overscanning parameter of described HDMI, when there being fringing, the TV programme of problem of edge point is when finishing, and described HDMI exports other the TV programme not having the problem of fringing, edge point.Now, because the overscanning parameter of described HDMI changes, program video is imperfect, in order to other TV programme making user normally can watch the output of described HDMI, when the TV programme monitoring the broadcasting of described HDMI changes, obtain the acquiescence overscanning parameter that described HDMI is corresponding; Utilize the TV programme that HDMI described in the acquiescence overscanning parameter display corresponding to described HDMI exports; Described acquiescence overscanning parameter is utilized to replace new overscanning parameter in the display properties table of described HDMI.Like this, automatically recover the acquiescence overscanning parameter in the display properties table of described HDMI, when making user watch other TV programme of described HDMI output, program video is complete.As shown in the above, the present invention has following beneficial effect:
Store the display tables of data arranged respectively to each HDMI, the display tables of data of each HDMI comprises the former overscanning parameter corresponding with it, receives the overscanning parameter setting instruction of the HDMI to the current shown program video of output that user sends; Resolve new overscanning parameter entrained in described overscanning parameter setting instruction; Utilize the program video that HDMI described in described new overscanning parameter adjustment exports; The former overscanning parameter in the display tables of data of described HDMI is replaced by described new overscanning parameter.Each HDMI has an one's own display tables of data, the former overscanning parameter corresponding with it is only had in the display tables of data of each HDMI, the overscanning parameter setting instruction that user sends at every turn only can change the overscanning parameter of the HDMI exporting current shown program video, also the former overscanning parameter in the display tables of data of described HDMI only can be upgraded by new overscanning parameter, namely the overscanning parameter setting instruction at every turn received is only applicable to the HDMI exporting current shown program video, the overscanning parameter in the display tables of data of other HDMI can not be affected, the program video that other HDMI export can not be had an impact, also just the overscanning parameter of user to other HDMI is not needed to reset, simplify user operation.
