An alternative method for obtaining video identification position information corresponding to video information and production line information, as shown in fig. 4, includes the following steps:

s11: and acquiring the video file and the video ID corresponding to the video file.

In step S11, the video configuration information may be obtained from the server, and the configuration information may be in a text type, such as chinese characters, letters, etc., or in a numerical type, such as numbers. In a specific application scenario, the configuration information may carry various video-related information, such as a video ID, a video address, and the like. The video address indicates the position of the terminal in the video library, and the terminal can watch or download the corresponding video file through the video address. And the terminal acquires the configuration information corresponding to the video ID sent by the server, and can distinguish and identify the video file through the configuration information.

S12: and determining the position information of the video identification corresponding to each production line according to the video file and the display strategy of each production line.

The step S12 specifically includes: detecting whether a video identifier exists in a frame picture of a video file corresponding to the video ID; if the video identification does not exist, determining that the position information of the video identification corresponding to each production line is empty; if the video identification exists, acquiring the position coordinate of the video identification in a frame picture of a video file, comparing the video identification with identification pictures allowed by each production line one by one, and judging whether the video identification meets the display requirement of the production line, if so, determining that the position information of the video identification corresponding to the production line is empty, and if not, determining the position coordinate as the position information of the video identification corresponding to the production line.

In an alternative embodiment, the frame pictures are image pictures of each frame of the video file as it is played. The method comprises the steps of detecting whether a video identifier exists in a frame picture of a video file, firstly determining a detection area in the frame picture, in an optional embodiment, determining the detection area of the video identifier in a playing picture of the video file, in another optional embodiment, recording the positions of the video identifiers marked on the video file provided by each content provider in advance by a server, recording the detection areas where the video identifiers are located one by one, and when the video identifiers need to be detected, acquiring the detection areas of the video identifiers in the frame picture from the server. The detection area may be determined in pixel positions in the frame picture. Then, whether a video identifier exists in the frame picture is detected in the detection area, in an optional embodiment, whether the video identifier exists in the frame picture can be determined by matching the image content of the detection area with a preset template of the video identifier, and in another optional embodiment, the image content in the frame picture can be directly subjected to feature recognition in an image recognition mode, so as to determine whether the video identifier exists in the frame picture. As an alternative implementation, the image content in the frame picture may be directly subjected to feature recognition through a SIFT algorithm, so as to determine whether the video identifier exists in the frame picture.

SIFT algorithms are used to detect and describe local features in images, which find extreme points in spatial dimensions and extract their position, Scale, rotation invariants, published by David L owe in 1999, well-summarized in 2004, whose application range includes object recognition, robotic map perception and navigation, image stitching, 3D model building, gesture recognition, image tracking, and aspect ratios, etc. description and detection of local image features can help to recognize objects, SIFT features are based on some local appearance interest points on objects independent of image size and rotation.

And carrying out video identification detection on the frame picture, and further determining the position information of the video identification in the frame picture if the video identification is detected. As an optional implementation manner, SIFT feature points can be searched in a frame picture through a SIFT algorithm, wherein the SIFT feature points comprise edge points of the frame picture and corner points of a video identifier; and calculating the position coordinates of the video identifier according to the edge points of the frame picture and the corner points of the video identifier, wherein the parameters of the position coordinates comprise the distance from the top right corner vertex of the video identifier to the right edge and the top edge of the frame picture respectively, and the width and the length of the video identifier. Referring to fig. 5, the video identifier is located at the upper right corner of the frame picture, the location information of the video identifier can be represented by a quadruple of coordinates, which is denoted as pos (x, y, w, h), where x denotes the shortest distance from the top right corner vertex of the video identifier to the right edge of the frame picture, y denotes the shortest distance from the top right corner vertex of the video identifier to the top edge of the frame picture, w denotes the width of the video identifier, h denotes the length of the video identifier, and the units of x, y, w, and h are pixels.

In an alternative embodiment, the display strategy can be to allow the video identifier not to appear in the video playing picture and to allow information such as a television station logo, a live broadcast character and an advertisement L OGO which both meet the requirements of the central office of the radio and television and meet the requirements of the production line.

S13: and storing the video ID, the production line ID of the production line and the position information corresponding to the video identification.

And correspondingly storing the video ID, the production line ID and the position information into a media asset system as shown in table 1.

Table 1:

production line	Video	Location information
			PL01	Video01	pos(0,0,0,0)
PL02	Video01	pos(x1,y1,w1,h1)
			PL03	Video01	pos(x2,y2,w2,h2)
PL04	Video01	pos(0,0,0,0)

In an optional embodiment, each production line corresponds to its own mask picture, and the correspondence between the production line and the mask picture may be embodied by a mask configuration table, as shown in table 2. In one embodiment, the masking picture information may be a url pointing to the remote picture, and in another embodiment, the masking picture information may be a path pointing to the local picture.

Table 2:

production line	Mask picture information
		PL01	mask.logo1
PL02	mask.logo2
		PL03	mask.logo3

Step two: receiving a playing operation instruction of a video file, and acquiring a video ID of the video file and a production line ID of a video client.

In an optional embodiment, when a user performs a play operation on a selected video file, the client receives a play operation instruction for the video file, and obtains video configuration information and production line configuration information of the selected video file, where the video configuration information may be a video ID of the video file, the production line configuration information is configured and stored in the client in advance, and the production line configuration information may be a production line ID, where the production line ID is used to identify television manufacturer information or television operator information.

Step three: and acquiring the position information of the video identifier in the frame picture of the video file according to the video ID and the production line ID.

The third step specifically comprises:

s31: a client generates a position information acquisition request carrying a video ID and a production line ID;

s32: the client sends the position information acquisition request to a server, the server inquires in a media resource system according to a video ID and a production line ID carried by the position information acquisition request to obtain corresponding position information, and the position information is returned to the client;

s33: and the client receives the position information searched and returned by the server according to the video ID and the production line ID.

Step four: judging whether the video identification needs to be shielded according to the position information, if so, acquiring a mask picture matched with the production line ID, and shielding the video identification according to the mask picture and the position information.

After receiving the location information returned by the server, the client determines whether the location information is null, in an optional embodiment, the location information is represented by a location coordinate, when the location coordinate is (0,0,0,0), the location information is null, otherwise, the location information is not null; in another optional embodiment, if the client does not receive the location information returned by the server, the location information returned by the server may be regarded as null, otherwise, the location information is not null. If the position information is judged to be null, the video identification does not exist in the video file or the video identification existing in the video file meets the production line requirement, so that the video identification does not need to be processed, and the video file can be directly played. If the position information is judged not to be null, the video identification exists in the video file and is not in line with the production requirement, and the video identification needs to be processed. In an alternative embodiment, the method of processing the video identity comprises the steps of:

s41: and acquiring a mask picture corresponding to the ID of the production line.

The method specifically comprises the following steps: the client generates a mask picture acquisition request carrying the ID of the production line; the client sends the mask picture acquisition request to a server so that the server can inquire in a mask configuration table according to the production line ID to obtain corresponding mask picture information and send the mask picture information to the client; and the client receives the mask picture information returned by the server and extracts the mask picture according to the mask picture information.

S42: and displaying the mask picture on a playing picture of the video client in an overlapping mode according to the position information, and blocking the video identifier in the frame picture of the video file.

When the video file is played on the client, the mask picture is overlapped and displayed on the playing picture of the video client, and the video identifier in the video file is covered by the mask picture, so that the video identifier of the original video file is not arranged on the playing picture watched by a video terminal user. Compared with the prior art for processing the video identification, the mode of shielding the video identification by the mask picture does not need to change the original video file, can ensure the quality of the video image, and realizes better playing effect at a television end.

In an alternative embodiment, between steps S41 and S42, the method further includes: and adjusting the size of the mask picture to be consistent with the size of the video identifier according to the position information. That is, the size of the mask picture is adjusted according to the position coordinates of the video identifier, for example, the width and the length of the video identifier can be taken as references, the width and the length of the mask picture and the video identifier are adjusted to be consistent, and the size of the mask picture can be adjusted according to the width and the length of the video identifier, so that the mask picture can just completely cover the video identifier. In step S42, the adjusted mask picture is displayed in an overlapping manner on the video identifier of the video file.

In an actual working environment, the sizes of various terminals are different, so that the problems of video frame lifting and scaling can be caused when a video is played, the mask picture needs to be correspondingly processed under the condition, otherwise, the mask picture is dislocated, and the video identification cannot be completely shielded.

As an optional implementation manner, when scaling the video frame, scaling the mask picture at the same time by an equal ratio, specifically includes the following steps:

1) the video client acquires the width and height of a terminal screen when starting, and the width and height are recorded as (w1, h 1);

2) when the video client plays the video, acquiring the width and the height of a video frame picture according to the ID of the video, and recording as (w2, h 2);

3) the video client calculates the scaling, w1/w2 ═ pw and h1/h2 ═ ph, pw and ph being the width and height scaling, respectively.

4) The video client scales the video frame picture according to pw or ph (or one of pw and ph); and simultaneously, the mask picture is zoomed according to pw or ph (alternatively, one of pw and ph), and the zooming proportion of the mask picture is consistent with that of the frame picture.

After the steps are processed, no matter what screen size is displayed on the terminal, the mask picture cannot be dislocated finally.

In an optional embodiment, step S42 is followed by: when the fact that the zooming operation is carried out on the playing picture of the video is detected, the zooming ratio of the playing picture of the video is obtained, and the mask picture is zoomed according to the zooming ratio.

The method comprises the steps that a user can adjust the size of a playing picture through zooming operation in the video playing process, when the client detects that the user performs zooming operation on the playing picture of the video, the client obtains the zooming ratio of the video playing picture, and the video picture and a mask picture are zoomed at the same time according to the zooming ratio. Therefore, the video identification can be completely shielded by the masking picture no matter how the size of the playing picture is changed.
