Embodiment
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, video data display packing the first embodiment schematic flow sheet that Fig. 1 is display terminal of the present invention, the method comprises:
When S10, display terminal receive video data to be played, resolve the preset direction video resolution of the video data receiving.
The display terminal of the setting of public that this display terminal can Wei megastore, supermarket, hotel lobby, dining room, movie theatre and other stream of people converge can be also other terminal with Presentation Function, as computer, mobile phone etc.
This display terminal can receive video data to be played by USB interface and usb data line from miscellaneous equipment, also can receive video data to be played by wireless communication mode, as received video data to be played by bluetooth, wifi.
In this step S10, resolve the preset direction video resolution of the video data receiving, this preset direction video resolution can be horizontal video resolution, can be also longitudinal video resolution, can be also laterally video resolution and longitudinally video resolution.In this step, can resolve the horizontal video resolution of the video data of reception, also can resolve longitudinal video resolution of the video data of reception, also can resolve horizontal video resolution and longitudinal video resolution of the video data of reception simultaneously.This video resolution is the height/wide pixel value of video.
Whether S11, this display terminal obtain its preset direction physical resolution, analyze the preset direction physical resolution of obtaining and equate with the preset direction video resolution of parsing, if unequal, perform step S12; If equate, perform step S14.
In this step S11, display terminal obtains its preset direction physical resolution, and this preset direction physical resolution can be horizontal physical resolution, can be also longitudinal physical resolution, can be also laterally physical resolution and longitudinally physical resolution.In this step, can obtain the horizontal physical resolution of this display terminal, also can obtain longitudinal physical resolution of this display terminal, also can obtain horizontal physical resolution and longitudinal physical resolution of this display terminal.This preset direction physical resolution can be pre-stored in this display terminal memory, also can be stored in the background server of this display terminal (this display terminal can read preset direction physical resolution from background server).
In this step S11, whether whether the preset direction physical resolution that analysis is obtained equate with the preset direction video resolution of parsing, as analyzed the horizontal physical resolution of obtaining, whether equate, analyze longitudinal physical resolution of obtaining equate with longitudinal video resolution of parsing with the horizontal video resolution of parsing.
S12, this display terminal are adjusted the preset direction video resolution of this video data according to the preset direction video resolution of resolving and the ratio of the preset direction physical resolution of obtaining, so that the preset direction video resolution of this video data and the preset direction physical resolution of this display terminal equate.
In this step, display terminal is adjusted the preset direction video resolution of this video data according to the preset direction video resolution of resolving and the ratio of the preset direction physical resolution of obtaining, this adjustment comprises that video data to obtaining carries out equal proportion in preset direction resolution and amplifies adjustments, scaled down adjustment, non-linear amplification adjustment or non-linearly dwindle adjustment, according to the ratio of the preset direction video resolution of resolving and the preset direction physical resolution obtained, selects the suitable adjustment mode in above-mentioned 4 kinds of adjustment modes.
S13, this display terminal are by the video data output display after adjusting.
This display terminal is exported the video data after adjusting, and can make this display terminal of video adaptation of reception, reaches best result of broadcast, and there will not be screen black surround, displaying contents to exceed the problems such as screen in this display terminal.
S14, this display terminal are by the video data output display to be played receiving.
In this step S14, when the video data to be played receiving (this video data to be played mates with this display terminal) when preset direction video resolution equates with display terminal preset direction physical resolution, do not need video data to be played to adjust, can be directly by video data to be played at display terminal output display.
With reference to Fig. 2, video data display packing the second embodiment schematic flow sheet that Fig. 2 is display terminal of the present invention.
Video data display packing the first embodiment based on above-mentioned display terminal, this preset direction comprises horizontal and vertical, the method comprises:
When S20, display terminal receive video data to be played, resolve horizontal video resolution and longitudinal video resolution of the video data receiving.
The display terminal of the setting of public that this display terminal can Wei megastore, supermarket, hotel lobby, dining room, movie theatre and other stream of people converge can be also other terminal with Presentation Function, as computer, mobile phone etc.
This display terminal can receive video data to be played by USB interface and usb data line from miscellaneous equipment, also can receive video data to be played by wireless communication mode, as received video data to be played by bluetooth, wifi.
In this step S20, resolve horizontal video resolution and longitudinal video resolution of the video data receiving, the height that this video resolution is video/wide pixel value.As the horizontal video resolution that is resolved to the video data of reception is 960, longitudinally video resolution is 540, and the video resolution that is resolved to the video data of reception is: 960x540.
Whether S21, this display terminal obtain its horizontal physical resolution and longitudinal physical resolution, analyze the horizontal physical resolution of obtaining and equate with the horizontal video resolution of parsing, if unequal, perform step S22, if equate, perform step S23.
In this step S21, display terminal obtains its horizontal physical resolution and longitudinal physical resolution, as the horizontal physical resolution that gets this display terminal is 1920, longitudinally physical resolution is 1080, and the physical resolution that gets this display terminal is: 1920x1080.In this step S21, whether analyze this horizontal physical resolution of obtaining equates with the horizontal video resolution of parsing, as the horizontal physical resolution of obtaining is 1920, the horizontal video resolution of resolving is 960, the horizontal video resolution that can find out horizontal physical resolution that this obtains and parsing is unequal, need to adjust accordingly the horizontal video resolution of video data, if the horizontal physical resolution when obtaining is 1920, the horizontal video resolution of resolving is 1920, can find out that this horizontal physical resolution of obtaining equates with the horizontal video resolution of parsing, do not need the horizontal video resolution of video data to adjust.
S22, according to the horizontal video resolution of resolving, with the first ratio N1 of the horizontal physical resolution of obtaining, the horizontal video resolution of this video data is adjusted, so that the horizontal video resolution of this video data and the horizontal physical resolution of this display terminal equate; Then perform step S23.
