Abstract
The invention discloses a method for controlling the HDMI (high-definition multimedia interface) output and selecting the output resolution. According to the method, HDMI signals are transmitted to a high-definition television. The method comprises the following steps of entering a user set HDMI output resolution operation interface; selecting whether to close the HDMI output or not, if so, quitting the operation after closing the HDMI image output, and otherwise, executing a next step; and selecting the output HDMI image resolution by users, and quitting the operation interface after the output resolution selection by the users. The method provided by the invention has the advantages that the selective output can be realized according to the requirements of the users, meanwhile, the output resolution is selected, the privacy of the users can be effectively protected, and in addition, the output resolution can be controlled.
Description
Technical field
The present invention relates to a kind of HDMI technology, particularly relate to the method for a kind of HDMI of control output and selection output resolution ratio.
Background technology
Development along with smart mobile phone; Increasing mobile phone is supported the (abbreviation of English High Definition Multimedia Interface of HDMI technology; Be the high-definition multimedia technology), through HDMI the demonstration on the screen of mobile phone is outputed on the HDTV, play HD video etc.The mobile phone of at present a lot of utilization HDMI technology all is to connect after HDMI Adapter connects HDTV; The mobile phone screen is gone up content displayed and is just outputed on the TV automatically; Whether the user can't go control will export from the mobile phone application interface, thereby also can't reach the purpose of protection privacy of user.The resolution of the output resolution coupling back that to be the EDID (the inside comprises the resolution information of TV) that removes to discern TV by software support with mobile phone is the output ultimate resolution automatically, and the user can't independently select to want the resolution exported.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; The method of a kind of HDMI of control output and selection output resolution ratio is provided, can selectively exports, select the resolution of output simultaneously according to user's demand; Protection user's that can be easily and effectively privacy, and control output resolution ratio.
In order to achieve the above object, the technical scheme that the present invention adopts is, a kind of method of controlling HDMI output and selecting output resolution ratio, and with HDMI signal conveys to high definition TV, its step is following:
Step 1, entering user are provided with the operation interface of HDMI output resolution ratio;
Whether step 2, selection close HDMI output, are then to close the output of HDMI image to retreat out operation, otherwise carry out next step;
Step 4.1, judging whether TV supports 720 pixels, be then to be set to output of 720 pixels and execution in step 5, otherwise the prompting user does not support the resolution of 720 pixels, directly exports the resolution and the execution in step 5 of 480 pixels;
Whether step 4.2, judges support 1080 pixels, be then to be set to output of 1080 pixels and execution in step 5, otherwise the prompting user does not support the resolution of 1080 pixels, and execution in step 4.1;
Further, described user selects to export automatically then system's ultimate resolution output of the current TV support of selection automatically.
Further, described HDMI output comprises the All Files in the mobile phone.
Compared with prior art, the invention has the beneficial effects as follows: can selectively export according to user's demand, select the resolution of output simultaneously, protection user's that can be easily and effectively privacy, and control output resolution ratio.
Description of drawings
Fig. 1 is the inventive method flow chart.
Embodiment
Purport of the present invention is to overcome the deficiency of prior art, and the method for a kind of HDMI of control output and selection output resolution ratio is provided, and with HDMI signal conveys to high definition TV, its step is following: get into the operation interface that the user is provided with the HDMI output resolution ratio; Select whether to close HDMI output, be then to close the output of HDMI image to retreat out operation, otherwise carry out next step; The user selects the resolution of the HDMI image of TV output, retreats out operation interface according to user's selection output resolution ratio.The present invention can selectively export according to user's demand, selects the resolution of output simultaneously, protection user's that can be easily and effectively privacy, and control output resolution ratio.
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that technical characterictic of the present invention and advantage are carried out more deep annotation.
Method flow diagram of the present invention is as shown in Figure 1, a kind of method of controlling HDMI output and selecting output resolution ratio, and with HDMI signal conveys to high definition TV, its step is following through mobile phone USB interface:
Step 1, entering user are provided with the operation interface of HDMI output resolution ratio;
Whether step 2, selection close HDMI output, are then to close the output of HDMI image to retreat out operation, otherwise carry out next step;
Step 4.1, judging whether TV supports 720 pixels, be then to be set to output of 720 pixels and execution in step 5, otherwise the prompting user does not support the resolution of 720 pixels, directly exports the resolution and the execution in step 5 of 480 pixels;
Whether step 4.2, judges support 1080 pixels, be then to be set to output of 1080 pixels and execution in step 5, otherwise the prompting user does not support the resolution of 1080 pixels, and execution in step 4.1;
Further, described user selects to export automatically then system's ultimate resolution output of the current TV support of selection automatically.
Further, described HDMI output comprises the All Files in the mobile phone.
This method of mobile phone utilization can make the HDMI cellphone subscriber to control the output of HDMI easily and close through the user side interface; For example in displaying video, select output; When checking short message, select to close the privacy of protection oneself that like this can be easily and effectively; Simultaneously through the user side interface, the user can select oneself to want the resolution exported easily as required.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For one of ordinary skill in the art of the present invention, under the prerequisite that does not break away from the present invention's design, make simple change or optimization, all should be regarded as protection scope of the present invention.
Claims (3)
