In order to facilitate a better understanding of the embodiments of the present disclosure, a specific operational method of the video playing system according to the embodiments of the present disclosure would be discussed below by taking a home TV as an example of the video playing system according to the embodiments of the present disclosure. By referring to FIG. 7, the method comprises:
step 701 in which the personal information of the viewer is inputted and stored;
the personal information of the viewer is required to be inputted to the system of the home TV at first; in the present embodiment, by using a handheld remote controller as the video playing control apparatus to realize a wireless information transmission between the viewer and the video playing system, the identification information of the viewer, such as the fingerprints, and the personal information, such as the gender, the age group or an exact age, etc., can be inputted or modified, and the respective input personal information can be further edited and modified; a specific information inputting interface is as illustrated in FIG. 8.
step 702, in which the fingerprint information of the current viewer is acquired;
in this step, the identification information of the current viewer would be acquired with the handheld remote controller; in the present embodiment, the fingerprint information of the current viewer can be acquired by an optical fingerprint sensor, as an identifying module, on the remote controller and uploaded by a Bluetooth module in the remote controller; an appearance of an example of the remote controller according to the embodiments of the present disclosure is as illustrated in FIG. 9, which includes an optical fingerprint sensor for collecting the fingerprints and a Bluetooth module for transmitting the information wirelessly, but the remote controller according to the embodiments of the present disclosure is not limited thereto;
step 703, in which the fingerprint information of the current viewer is received and the matched personal information is retrieved;
in this step, the fingerprint information is compared with the pre-stored fingerprint information of the viewers after receiving the fingerprint information of the current viewer uploaded from the remote controller, and then the pre-stored personal information which is matched can be retrieved;
step 704, in which the corresponding viewing information is retrieved based on the matched personal information, and the playing of the video is controlled accordingly;
In this step, the corresponding viewing information can be retrieved based on the matched personal information, and the matched personal information can be classified, such that the viewing information for the respective categories can be obtained according to the different categories of matched personal information and the playing of the video is control led;
In the present embodiment, the detailed operations can be performed as follows. In a case in which the age of the current viewer is less than or equal to 18, the corresponding videos are shielded according to types of programs to be shielded, and the playing of the video would be stopped automatically if the viewing duration reaches the viewing time limitation, such as 3 hours; In a case in which the age of the current viewer is between 19 and 59, the playing of the video would be paused for 5 minutes and then be resumed if the viewing duration reaches the viewing time limitation, such as 3 hours; and In a case in which the age of the current viewer is greater than or equal to 60, the video playing reminder is provided according to a stored program preference. If the viewer likes to watch the traditional opera program, the control unit can provide a playing reminder at a time 10 minutes before the specific traditional opera program begins to be played, or switch to the specific traditional opera program directly when the program starts;
step 705, in which the playing of the video is controlled with the camera.
In the embodiments of the present disclosure, effective contour information of the current viewer can be captured by the camera, wherein the contour information is captured by the optical camera in a case in which the light is sufficient, while it is captured by the infrared camera in a case in which the environment is dim. The camera can be located on the top of the home TV, as illustrated in FIG. 10, but the embodiments of the present disclosure are not limited thereto. Also, the playing of the video can be controlled in time according to a feedback from the camera, and the playing of the video can be stopped when the camera fails to capture any contour information of the current viewer.
Furthermore, a specific action of the current viewer can be further determined with a trigger situation of the remote controller. The home TV would continue the playing of the video when the camera captures no active contour information of the current viewer but there is feedback on operation from the remote controller; further, the home TV would stop playing the video according to the feedback if the remote controller has not been triggered within 1 hour and no active contour information of the current viewer is captured. For example, in a specific operational process, a backlight source can be shut off at first to save energy, and then system signals are interrupted completely 3 hours later.
The whole process of the specific operation method for the video playing system according to the embodiments of the present disclosure has been discussed above.
It can be seen that, in the video playing control system and the control method according to the embodiments of the present disclosure, the identification information of the current viewer can be compared with the information as pre-stored to obtain a comparison result, so that an identification of the current viewer can be recognized, and in turn an intelligent playing control of the video can be realized according to the viewing information of the current viewer, and the power supply can be shut off in time with the camera or other feedback mechanism to save energy. The present disclosure has a good practicability and is well worth to be promoted.
Lastly, it should be understood that the embodiments described above are intended only to illustrate the solutions of the present disclosure instead of limiting a scope thereof. Although the embodiments of the present disclosure have been explained in details in connection with the above embodiments, those skilled in the art should understand that they can also make modifications on the solutions described in the above respective embodiments, or can also make equivalent replacements for a part of technical features therein.
