Abstract
The invention provides a method for automatically switching a display mode of a television. The method comprises the following steps: identifying a signal format received by the television; and automatically switching and setting the display mode according to the characteristic of the signal format based on signal format identification. The embodiment of the invention identifies and sets the display mode through identifying the signal format without increasing cost, thereby simplifying operation of a user.
Description
Technical field
The invention belongs to the television applications field, relate in particular to a kind of method and system of automatically transferring display mode of television set.
Background technology
Digital television system (DTV) is exactly the television system that overall processes such as shooting, editor, making, transmission, reception are all used digital technology, and Digital Television is that digital multimedia is handled and display terminal.
Along with the popularization of DTV, Digital Television market is increasing.Because the digital television program source format is numerous, and two kinds of main forms of 16:9 and 4:3 are arranged, under the situation in unlike signal source, need manually frequent 16:9 of switching and 4:3 display mode.
Need manually frequent 16:9 of switching and 4:3 display mode under the situation in unlike signal source, very inconvenient in the use.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of automatically transferring display mode of television set method, can be by display format is discerned and set in the differentiation of signal format.
The embodiment of the invention is achieved in that a kind of automatically transferring display mode of television set method, and described method comprises the steps: to discern the signal format that television set receives; And on the signal format base of recognition according to the characteristics of signal format, automatically switch and setting display mode.
The embodiment of the invention also provides a kind of automatically transferring display mode of television set system, and described system comprises: the signal identification module is used to discern the signal format that television set receives; And the display mode handover module, be used on the signal format base of recognition characteristics according to signal format, automatically switch and setting display mode.
The embodiment of the invention by display format is discerned and set in the differentiation of signal format, has been simplified user's operation on the basis that does not increase cost.
Description of drawings

Fig. 2 is the module figure of automatically transferring display mode of television set system that the embodiment of the invention provides.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.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.
The embodiment of the invention can be watched the program situation according to the user, selects display mode automatically, has exempted the trouble that former user needs the manual switchover display mode.
Fig. 1 is the automatically transferring display mode of television set method flow diagram that the embodiment of the invention provides, and existing details are as follows:
TV or display are wanted normal display image, all have the signal format recognition function.The embodiment of the invention according to the characteristics of signal format, automaticallyes switch and setting 4:3 or 16:9 pattern on the signal format base of recognition.
Because integrated analog/digital equipment need receive two kinds of digital and analog signalings, so following separately explanation:
For the signal that analog radio frequency receives and CVBS imports, generally all be the 4:3 signal, can be this input default the 4:3 pattern; When the identification signal form was above-mentioned signal, the switching display mode was 4:3.
For the VGA input,, be the 4:3 pattern all owing to generally only support VGA, SVGA, XGA pattern; When the identification signal form was above-mentioned signal, the switching display mode was 4:3.
For the YCBCR/YPBPR input terminal, owing to have only 480i/P, 576i/P, 1080i/P, 720P several modes; Generally speaking, 1080i/P, 720P are the 16:9 signals, and other patterns all are the 4:3 signals.Can distinguish out this two kinds of patterns in the combination by the line frequency field frequency thus, thereby set corresponding display mode; When the identification signal form was above-mentioned signal, if 1080i/P, 720P pattern, the switching display mode was 16:9.If other patterns, the switching display mode is 4:3.
For the HDMI input, same 1080i/P, 720P are the 16:9 signals, and other patterns all are the 4:3 signals.Can distinguish out this two kinds of patterns in the combination by the line frequency field frequency thus, thereby set corresponding display mode.
For digital television signals such as DVB-C and DVB-T, DTMB, in the information on services of digital stream, can judge 4:3 or 16:9 signal from 4 fields of stream_content.
For the digitized processing TV that does not have the Digital Television receiving function, except there not being the differentiation process of Digital Television, other parts are identical.
Fig. 2 is the module figure of automatically transferring display mode of television set system that the embodiment of the invention provides, and existing details are as follows: described automatically transferring display mode system comprises signal identification module 21 and display mode handover module 22.Described signal identification module 21 is used to discern the signal format that television set receives; Described display mode handover module 22 according to the characteristics of signal format, automaticallyes switch and setting display mode on the signal format base of recognition.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
