The cloud server is connected with the video player and used for receiving a display screen playing content judgment result and a picture content file transmitted by the video player.
In practical applications, the light sensor unit comprises one or more light sensors; when the light sensor unit includes a plurality of light sensors, each light sensor is used for detecting light of different colors at a set position of the display screen. Light sensor passes through the interface of electric wire connection to the video player mainboard, this light sensor has three kinds of specifications, can discern red respectively, green, blue, can use the light sensor of a certain colour alone, also can use the light sensor of three different colours to combine together, light sensor can produce the signal of telecommunication after detecting the light of these three kinds of colours, thereby received by the video player, the light sensor of different colours is connected to the interface of different serial numbers in the video player, the video player produces the colour that its correspondence can be confirmed through detecting a certain light sensor of different times.
In practical application, as shown in fig. 5 and 6, the setting position of the display screen is generally one of four corners, one of specific red, green and blue is added at a position corresponding to a played picture content file (video file or picture file), when the picture content file is played by the display screen, the corresponding position can display a specific color, and the normal display of the picture is not affected because the area of the specific color is very small.
The method comprises the steps of using one or more light sensors outside a display screen, fixing the light sensors on a structural part, pasting the structural part with the light sensors on the screen, enabling the light sensing surface of the light sensors to face the display screen, detecting specific color areas on the display screen, transmitting a result of whether the light sensors detect stable specific colors back to a video player while the display screen plays pictures, and if the light sensors detect the specific colors, obtaining corresponding electric signals, and if the light sensors do not detect the stable electric signals, indicating that the corresponding colors do not exist, namely the contents of the video player do not play.
If the display screen changes the signal source, the specific color will not be detected at the specific position detected by the light sensor, and even if the specific color appears occasionally, the specific color will not appear stably for a long time, so that the light sensor cannot generate an electric signal or the electric signal is also unstable.
The video player can transmit the playing information and the detection signal result back to the cloud server simultaneously when outputting the video signal. Software running on the server can mark the abnormal data uploaded by the video player and push the abnormal data to the terminal equipment. When the video player plays contents, whether a result generated by the electric signal of the sensor exists or not is uploaded to the cloud server through the network, the cloud server marks equipment without the electric signal of the light sensor in the video player, and media management software on the server identifies the equipment as abnormal and informs related operators. And finally obtaining a detection result.
The invention provides a using process of a monitoring system of screen playing contents, which comprises the following steps:
firstly, the light sensor is connected to the video player through a wire, so that data detected by the light sensor is identified by the video player. (three types of light sensors are available to detect red, blue and green, respectively.
Green is taken as an example below)
And secondly, adding colors to the electronic file of the picture through video software or picture editing software.
And thirdly, when the video player puts the picture signals on the connected display screen through the video line, the display screen displays the picture with the green mark, and only green is displayed at the lower right corner of the screen.
And fourthly, attaching the probe with the light sensor to the lower right corner of the screen, wherein the light sensor can detect a green picture to generate an electric signal, and the video player receives a signal generated by the sensor while playing the picture, so that the picture displayed by the display screen can be determined to be correct.
Fifthly, when the display screen is manually operated to play other contents, the lower right corner can not stably generate green, so that the light sensor can not generate an electric signal, or the screen can be judged not to play the contents of the video player when the green occasionally occurs.
According to actual needs, the light sensors attached to the screen can use a light sensor with a certain color, and can also use two or three sensors with different colors, and the video player can receive signals transmitted back by different sensors. For example: the 3 light sensors are numbered, red number 1, green number 2, and blue number 3. At this time, taking the content of the picture in front for playing as an example, the normally played picture corresponds to the green mark, when the video player plays the normally played picture, the video player should receive the electric signal of the number 2 (green) light sensor, if the video player does not receive the electric signal of the number 2 sensor while playing the normally played picture, the display screen does not have the green mark at the lower right corner, and the screen is indicated to play other contents.
The video player plays a common video or picture file, the video is in MP4 format, the picture is in JPG format, and a picture making tool such as Photoshop is used when making the file. The video production tool, such as Premiere, adds a color block at a set position.
The light sensor is integrated on a circuit board in a patch mode, and 3 light sensors with different colors can be simultaneously integrated on one circuit board due to the fact that the light sensor is small in size. The circuit board containing the light sensor is directly attached to the viewing side of the screen, so that the light sensor can detect the color of the screen, and the set position is the position of the set color in the picture content file, in this specific embodiment, the lower right corner of the screen of the display screen.
