FIG. 7 is a schematic structural diagram of a mobile terminal according to Embodiment 6 of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Since most TV shows currently have their corresponding icons, including TV shows, movies, news programs, sports events, talk shows, variety shows, and other programs, the program icons can be either patterns or text. It allows the viewer to quickly and easily understand the current program information, and the size of the icon is relatively small, does not affect the visual effect of the viewer, so most of the programs have such icons, which are generally displayed on the screen. A fixed position such as the lower right corner and the upper right corner, such as a news program, will have a "news feed" icon on the lower right corner. This icon contains the words "news feed" and the icon shape unique to the news feed. In the present application, such an identifier is referred to as an icon, and an area identified in the video program is referred to as an identification area of the video program. This logo will not change during the broadcast of the program, and at other times such as the advertising time, the icon will not exist or will change. Referring to FIG. 1 , a flow chart of a method for detecting a video of a mobile terminal according to a first embodiment of the present invention is provided. The method includes: Step S102: The mobile terminal periodically samples a fingerprint of an currently displayed video program to obtain a current identifier. image. When the video terminal plays the video program, the mobile terminal may periodically take a screenshot of the identification area of the video program being played, for example, for the identification area of the currently broadcasted news program, that is, the area where the word "news simulcast" is displayed, and the current screenshot is obtained. Identify the image to get the program information currently being played. The time of the timing can be flexibly set by a person skilled in the art according to actual needs. Step S104: The mobile terminal compares whether the current identification image is consistent with the preset reference identification image. The preset reference identification image is usually an image of an identification (icon) of a video program that is of interest to the user being played, may be set by a screenshot when the user starts the video program, or may be preset by the user, such as at a certain time. The screenshot is set when the news is broadcast, and is used in the subsequent playback. Thus, if the user is only interested in the news related program, it can be judged whether the program is played by comparison, and if so, the viewing is performed, otherwise, it can be performed. Other operations, such as entering the mobile terminal power saving mode. Step S106: If the mobile terminal compares the current identification image with the reference identification image, it determines that the video program changes. When the current identification image is inconsistent with the reference identification image, it indicates that the video program has changed, such as from news feed to advertisement. In the related art, the video program that cannot be found by the mobile terminal is changed in time, causing the user to have to watch certain programs (such as advertisements) that are not interested in order to continuously watch the program of interest (such as a TV series), thereby causing The extra power consumption of the terminal battery; if the terminal power is insufficient or the user wants to save the terminal power consumption, at this time, the user will manually turn off the display screen and the speaker of the mobile terminal to achieve the purpose of power saving, thereby increasing the operation burden of the user. And cause a lower user experience. In this embodiment, the mobile terminal can discover the replacement of the video program in time, and then can (1) automatically start the mobile terminal to enter the power saving mode, and reduce the power consumption of the terminal battery; or, (2) if the user desires to continuously watch certain programs. (such as a TV series), the mobile terminal can automatically enter the power saving mode first in the advertising period, and then, when the program starts to continue playing, the terminal can adopt the reminding method (such as ringing, information prompting, keyboard backlight prompt, etc.) Remind the user, that is: when the program changes from a serial to an advertisement, the terminal determines that the current identification image is inconsistent with the reference identification image, and considers that the terminal automatically enters the power saving mode when entering the advertisement period; and when the series starts to play the next episode, that is, the program From the advertisement to the serial drama, the terminal judges that the current logo image and the reference logo image are changed from inconsistency to consistency, and the reminder method (such as ringing, etc.) may be used to remind the user to continue the program. Through the above operations, the operation burden of the user is effectively reduced, and the user experience is improved. Referring to FIG. 2, a flow chart of steps of a video detection method for a mobile terminal according to a second embodiment of the present invention is shown. This embodiment takes a video program from news broadcast to advertisement replacement as an example. The mobile terminal video detection method in this embodiment includes: Step S202: Turn on the mobile terminal CMMB function. Step S204: Set the automatic power saving function of the mobile terminal. That is, setting the power saving mode of the mobile terminal, including setting the conditions for entering the power saving mode, and setting the display of the mobile terminal and the speaker to be turned off. Step S206: setting a reference identification image. After setting the automatic power saving function of the mobile terminal, the mobile terminal displays a pop-up automatic screenshot area box, and the user can move and adjust the position and size of the box through keyboard operation or touch screen operation, perform screenshots, and use the current screenshot as a screenshot. The reference identification image is saved to the central processing unit. Generally, the automatic screenshot area box is set to be smaller than the identification area of the video program. In this embodiment, the identification area of the news broadcast, that is, the "news broadcast" typeface area, may be taken as a reference identification image. Step S208: The mobile terminal performs a timing sampling screenshot on the currently played video program to obtain a current identification image. The mobile terminal samples a screen of the same area as the reference identification image in the display screen according to the set time interval, and acquires the current identification image. Further, the currently identified current identification image may also be stored in the central processing unit. The sampling screenshot time interval can be flexibly set by a person skilled in the art according to actual needs. In this embodiment, after a number of times of sampling the screenshots, when the video program becomes an advertisement, a screenshot of the current advertisement program is taken. Step S210: The mobile terminal compares whether the current identification image and the reference identification image are consistent. If not, step S212 is performed; if yes, step S214 is performed. Whether or not the comparison is consistent may be judged based on the similarity between the current identification image and the reference identification image, and if the similarity exceeds the set threshold, it is determined to be inconsistent. By setting the threshold reasonably, it is possible to accurately and effectively determine whether the images are consistent. Of course, those skilled in the art can also adopt other existing image comparison methods, which are not limited in the present invention. In this embodiment, the mobile terminal compares whether the image of the intercepted advertisement program is consistent with the identification image of the previously stored news related program. Step S212: The mobile terminal determines that the current identification image is inconsistent with the reference identification image, enters a power saving mode, and turns off the LCD backlight or the speaker. In this embodiment, the mobile terminal determines that the identification image changes by comparing the current identification image acquired immediately with the previous reference identification image, determines that the current video program is an advertisement program, and enters the power saving mode according to the setting of step S204. Step S214: The mobile terminal determines that the current identification image is consistent with the reference identification image, and plays the video program normally. After step S212 and step S214, the mobile terminal returns to step S208 to cycle through the sample screenshot detection comparison. In this embodiment, by identifying and comparing the identification images of the sampled screenshots, it is determined whether the mobile terminal is playing a normal television program or an advertisement program, and if it is an advertisement program, turning off the backlight of the liquid crystal display LCD or even raising the sound. In order to solve the problem that the CMMB terminal battery is used too short, thereby reducing the power consumption of the terminal, prolonging the playing time of the CMMB terminal, and increasing the time for the user to actually watch the video program. Moreover, manually setting the screenshot area is relatively low in system requirements and high in accuracy. Referring to FIG. 3, a flow chart of a method for detecting a video of a mobile terminal according to a third embodiment of the present invention includes: Step S302: Turn on the CMMB function of the mobile terminal. Step S304: Set the automatic power saving function of the mobile terminal. Step S306: Set a reference identification image. Specifically, the mobile terminal can automatically detect the identification area of the video program by using preset automatic detection software, and then perform a screenshot to obtain a first reference identification image. Then, the time set by the interval, such as 30S, is again screen shot in the same location and area, and the second reference identification image is obtained, and the two identification images are compared. If they are consistent, the video program is considered to be a video of interest to the user. Program, set any one of the logo images as the reference logo image; if it is inconsistent, it is considered that the user has changed the channel, or the video program has been replaced, then the screenshot is compared after the set time is again, until the screenshot is consistent before and after the set time interval. It should be noted that a person skilled in the art can also set a multiple sampling screenshot comparison according to actual needs, which is not limited by the present invention. Step S308: The mobile terminal performs a timing sampling screenshot on the currently played video program to obtain a current identification image. The mobile terminal samples a screen of the same area as the reference identification image in the display screen according to the set time interval, and acquires the current identification image. Step S310: The mobile terminal compares whether the current identification image and the reference identification image are consistent. If not, step S312 is performed; if yes, step S314 is performed. Step S312: The mobile terminal determines that the current identification image is inconsistent with the reference identification image, and prompts the user to replace the video program. Tips can be ringing, or other ways to get the user's attention. It is also possible to set subsequent operations after the prompt, such as providing access to the power saving mode selection, or changing other program selections, or continuing to watch the selection and the like. Step S314: The mobile terminal determines that the current identification image is consistent with the reference identification image, and plays the video program normally. After step S312 and step S314, the mobile terminal returns to step S308 to cycle the sample screenshot detection comparison. It should be noted that, if the current identification image and the reference identification image become identical again by the inconsistency, the mobile terminal may remind the user that the video program has changed again, and return the video program identified by the reference identification image. In this embodiment, the software automatically detects and determines the identification area of the video program, reduces the user operation burden, and improves the user experience. Referring to FIG. 4, a flow chart of a method for detecting a video of a mobile terminal according to a fourth embodiment of the present invention includes the following steps: Step S402: Turn on the CMMB function of the mobile terminal. Step S404: Set the automatic power saving function of the mobile terminal. Step S406: Set a plurality of reference identification images. In this embodiment, the reference identification image is set to be plural. Step S408: The mobile terminal performs a timing sampling screenshot on the currently played video program to obtain a current identification image. The mobile terminal samples a screen of the same area as the reference identification image in the display screen according to the set time interval, and acquires the current identification image. Step S410: The mobile terminal compares whether the current identification image and the reference identification image are consistent. If not, step S412 is performed; if they are consistent, the program is normally played. Specifically, the mobile terminal compares whether the current identification image is consistent with each reference identification image, and if it is consistent with any one of the reference identification images, the current identification image is considered to be consistent with the reference identification image. Step S412: The mobile terminal determines that the current identification image is inconsistent with the reference identification image, enters a power saving mode, and turns off the LCD backlight or the speaker.
