Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In an embodiment of the present invention; After obtaining the capable field information of incoming video signal; Directly by user's input video type; Thereby only need contrast the pairing capable field information of video type of the capable field information obtained and user input, when the row field information was identical, incoming video signal was the video type of this user's input.
Fig. 1 shows the identification process of the vision signal that the embodiment of the invention provides, and details are as follows:
In step S101, obtain the capable field information of incoming video signal.The row field information comprises line frequency, field frequency, line width, information such as field width.For the capable field information that makes the vision signal of obtaining is more stable, can repeatedly obtain capable field information usually, when the error between the capable field information of repeatedly obtaining in allowed limits the time, assert that then the capable field information of obtaining is in the main true.As embodiments of the invention, can remove some peaks and minimum in a plurality of capable field information earlier, calculate the mean value of residue row field information again, with the end value of this mean value as the capable field information of obtaining.
In step S102, receive the video type information of user's input.As embodiments of the invention, the user can be with video type information input video terminal presentation facility before video terminal display device receives the vision signal input or when receiving vision signal.Before video terminal display device received the vision signal input, the user can show a video type information input interface through pressing the video type enter key on video terminal display device, and the user is the input video type information under this interface.Wherein, the video type enter key can be existing key on remote controller or the video terminal display device or newly-increased key.Certainly, also can be when receiving vision signal, display video type information inputting interface is by user's input video type information.
In step S103, the number of the video type of recording user input.As embodiments of the invention, a video type number value P can be set, with the number of P recorder to the video type of user's input, wherein, the initial value of P is 0.When receiving another video type through video type information input interface input of user, video type number value P just adds 1.
In step S104, judge whether the number of the video type of input surpasses a definite value M.Judge promptly whether video type number value P surpasses M, and wherein, M is one and is not less than 1 integer.
In step S105, if the number of the video type of input is no more than M, the pairing capable field information of the capable field information that then will obtain and this video type compares.Owing in video terminal display device, store various video type information and the pairing capable field information of each video type that this video terminal display device is supported, the pairing capable field information of then can be directly the capable field information of obtaining and user being imported of video type compares.
In step S106; The M that outnumbers as if the video type of importing; Then start automatic identification step, the pairing capable field information of each video type that capable field information that is about to obtain and video terminal display device are supported contrasts one by one, the immediate capable field information of the capable field information of finding out and obtaining; Thereby find out the video type of mating most, execution in step S108 with incoming video signal.
In step S107, judge whether the row field information is identical.Judge whether the capable field information of obtaining is identical with the pairing capable field information of video type of user's input.
In step S108, show the vision signal of input by this video type.If the capable field information of obtaining is identical with the pairing capable field information of video type of user's input, explain that then the video type that the user imports is correct, then video type is discerned successfully, then can show incoming video signal according to the relevant information of this video type.Perhaps when video type number value P surpasses M, show incoming video signal according to the video type of mating most with incoming video signal that finds.
In step S109, output error message.If the row field information is inequality, then on the screen of video terminal display device, show miscue information.As embodiments of the invention, after showing miscue information, can also eject the video type information input interface, re-enter to make things convenient for the user.Certainly, also can in output error message, finish whole process.
When user's input video type information; Embodiments of the invention are provided with a video type number value P; With the number of P recorder to the video type of user's input; When P surpasses a definite value M, start automatic identification step, the pairing capable field information of each video type that capable field information that is about to obtain and video terminal display device are supported contrasts one by one; The immediate capable field information of the capable field information of finding out and obtaining, thus find out the video type of mating most with incoming video signal.Like this, when the video type mistake of user input, can let the user re-enter, and the video type of user's input then start automatic identification step when M mistake occurring.Add up when importing different video signals for fear of video type number value P, when video type was discerned successfully, video type number value P just carried out 0 operation clearly.
Fig. 2 shows the structure of the vision signal recognition system that the embodiment of the invention provides, and this vision signal recognition system can be the unit that is built in software unit, hardware cell or software and hardware combining in the video terminal display device.
Row field information acquisition module 21 obtains the capable field information of incoming video signal; Receive the video type information of user's input again by video type information receiving module 22; Logging modle 23 is the number of the video type of recording user input again; When the input video type outnumber a definite value M time; Contrast is searched the pairing capable field information of each video type that capable field information that module 24 will obtain and video terminal display device support and is contrasted one by one, finds out the video type of mating most with incoming video signal; When the number of the video type of importing is no more than a definite value M; The pairing capable field information of video type of contrast identification module 25 these row field information of contrast and this user input; When the row field information is identical; With the video type of incoming video signal as this user input, when the row field information was inequality, miscue module 26 output error informations were also received the video type information of user's input again by video type information receiving module 22.
In an embodiment of the present invention; After obtaining the capable field information of incoming video signal; Directly by user's input video type; Thereby only need contrast the pairing capable field information of video type of the capable field information obtained and user input, when the row field information was identical, incoming video signal was the video type of this user's input.When row field information when inequality, i.e. during the video type mistake of user's input, can let the user re-enter, and the video type of user's input then start automatic identification step when M mistake occurring.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
