All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The video playing method provided by the embodiment of the invention can be applied to a scene of malicious attack behavior identification, for example, when a video playing terminal detects a three-dimensional video playing signal input aiming at a target program, the video playing terminal acquires a playing visual angle parameter carried by the three-dimensional video playing signal and a program identifier of the target program, and sends a video acquiring request carrying the program identifier and the playing visual angle parameter to a server, after receiving the request, the server acquires playing video data based on the program identifier and the playing visual angle parameter, performs three-dimensional synthesis processing on the playing video data, and generates a first storage address of the playing video data after the three-dimensional synthesis processing and provides the first storage address to the video playing terminal, so that the video playing terminal plays the playing video data after the three-dimensional synthesis processing based on the first storage address.

The video playing terminal related to the embodiment of the present invention may be a 3D television terminal device or a mobile terminal having a 3D video playing function, which is accessed to the internet through a set top box or a computer to implement services such as a digital television, a time-shift television, an interactive television, etc., and may be a terminal device such as a smart phone, a tablet computer, a Mobile Internet Device (MID), etc., and the server related to the embodiment of the present invention may be a computer device having management resources and providing data support for the video playing terminal, for example, may be a server having strong data carrying capacity and processing capacity.

The following describes in detail a video playing method provided by an embodiment of the present invention with reference to fig. 1 to 11.

Referring to fig. 1, a flow diagram of a video playing method is provided in the embodiment of the present invention, which is described with a video playing terminal and a server as two sides, and as shown in fig. 1, the method in the embodiment of the present invention may include the following steps S101 to S104.

S101, when a video playing terminal detects a three-dimensional video playing signal input aiming at a target program, the video playing terminal acquires a playing visual angle parameter carried by the three-dimensional video playing signal and a program identifier of the target program, and sends a video acquiring request carrying the program identifier and the playing visual angle parameter to a server;

it is to be understood that the playing view parameter may include one of the view parameters playable by the user in the target program, and may also include a default view parameter when not selected by the user, that is, a set view parameter (e.g., a main view parameter). The playing view angle parameter is determined by a video recording terminal, that is, at least one video recording terminal is adopted to record in a recording site of a target program, each video recording terminal adopts one recording view angle parameter, and the recording view angle parameter is the playing view angle parameter after being sent to the video playing terminal. Optionally, the playing view parameter may be displayed by the video playing terminal, for example, in a list form.

The program identifier is used for uniquely identifying the target program, and may be the name of the target program, or the broadcast channel and broadcast time of the target program.

In the specific implementation, when a user performs a touch operation on a video playing interface of the video playing terminal, inputs voice information through a receiver of the video playing terminal, inputs gesture actions through a camera of the video playing terminal, and the like, the video playing terminal identifies the received operation and identifies the operation as a three-dimensional video playing signal for a target program, analyzes the signal, extracts information such as a playing view angle parameter carried by the signal and a program identifier of the target program, generates a video acquisition request based on the extracted information, and sends the generated request to a server. The three-dimensional video playing signal can be a three-dimensional video live broadcasting signal and can also be a three-dimensional video recording and playing signal. It should be noted that the video playing terminal may support a 3D playing mode and a 2D playing mode at the same time, and in a feasible implementation manner, the acquired three-dimensional video playing signal is determined by selecting a touch key of the 3D playing mode.

Where 3D is a concept relative to a 2D plane, with three dimensions: height, width, and depth. The world in which humans live is a three-dimensional space, and objects observed in the real world also have three dimensions. The 3D image is consistent with the scene of the habit of people in real life, and is more three-dimensional and vivid; meanwhile, the stereoscopic impression and the depth of field of the 3D image enable a viewer to have an immersive sensation, and the immersive sensation is strong; in addition, various strong visual impacts can be made by utilizing the characteristics of the 3D images, such as live sports events, live concert and various macro movie scenes, and the visual impact effect is strong.

S102, the server receives the video acquisition request, acquires the program identifier and the playing view angle parameter in the video acquisition request, and acquires playing video data based on the program identifier and the playing view angle parameter;

it is understood that the video data source for playing the video data as the target program may be a video stream or a code stream.

In the specific implementation, after receiving a video acquisition request sent by a video playing terminal, a server analyzes the request, extracts a program identifier and a playing view angle parameter carried by the request, simultaneously receives a recorded video data set corresponding to the program identifier acquired by a video recording terminal in real time, and then selects playing video data corresponding to the playing view angle parameter from the recorded video data set. Or after extracting the program identifier and the playing angle of view parameter carried by the request, searching a recorded video data set corresponding to the program identifier in a cached database, and then selecting the playing video data corresponding to the playing angle of view parameter from the recorded video data set.

S103, the server carries out three-dimensional synthesis processing on the played video data, acquires a first storage address of the played video data after the three-dimensional synthesis processing, and sends the first storage address to the video playing terminal;

it is understood that, since the video data includes a plurality of frames of image data, the three-dimensional composition processing of the video data is actually three-dimensional composition processing of an image. The processing process of the existing three-dimensional image synthesis algorithm mainly comprises the steps of image cutting, optimal illumination surface searching, light source direction estimation and image synthesis. Currently, there are several common 3D synthesis techniques: 1) the color difference type 3D stereo imaging has low technical difficulty and low cost, but the 3D image quality effect is not ideal, and the image and the picture edge are easy to color cast; 2) the shutter type 3D technology has relatively more resources, great propaganda and promotion force of manufacturers, excellent 3D effect and high price of shutter glasses; 3) the polarized light 3D technology has the advantages that polarized light glasses are low in price, excellent in 3D effect and large in market share, but installation and debugging are complex, cost is not low, picture resolution is reduced by half, and full high definition is difficult to achieve; 4) the naked eye type 3D technology can ensure the resolution and the light transmittance, the existing design framework is not influenced, the 3D display effect is excellent, the technology is still developed, and the product is immature; 5) holography is a perfect 3D technology in theory, and 3D images with different angles can be obtained when the images are viewed from different angles. The hologram can be applied to nondestructive industrial inspection, ultrasonic holography, holographic microscopy, holographic memory, holographic film and television. However, due to the complexity of the technology, holography has not been commercially applied in the above-mentioned fields. In the embodiment of the present invention, any one or more of the above 3D synthesis techniques may be used to perform three-dimensional synthesis processing on the acquired playing video data.

The playing video data comprises recording video data corresponding to playing visual angle parameters and recording video data corresponding to recording visual angle parameters adjacent to the playing visual angle parameters.

In the specific implementation, the server performs data conversion on the video recording devices on two sides of the selected visual angle and the multiple paths of video streams of the video recording devices with the selected visual angle by adopting a three-dimensional synthesis processing technology to obtain parallel data of the multiple paths of video streams, performs 3D synthesis on the parallel data, stores the 3D synthesized data, generates a first storage address, and provides the first storage address for the video playing terminal. The data conversion and 3D synthesis of the multiple video streams are performed on each frame of image data, that is, the data conversion and 3D synthesis are performed on the current image data corresponding to the playing angle of view parameter and the current image data corresponding to the angle of view parameters on the left and right sides of the playing angle of view parameter, and then the 3D synthesis processing is performed on the next frame of image data in the same manner, and the processing is sequentially performed until all the playing video data are processed.

And S104, the video playing terminal plays the played video data after the three-dimensional synthesis processing based on the first storage address.

In the specific implementation, the video playing terminal calls the playing video data corresponding to the first storage address, and loads and displays the playing video data by adopting an image display technology and an audio playing technology.

Referring to fig. 2, a schematic flow chart of another video playing method is provided in the embodiment of the present invention, which is described with a video playing terminal and a server side, and as shown in fig. 2, the method in the embodiment of the present invention may include the following steps S201 to S213.

S201, when a video playing terminal detects a three-dimensional video playing signal input aiming at a target program, the video playing terminal acquires a playing visual angle parameter carried by the three-dimensional video playing signal and a program identifier of the target program, and sends a video acquiring request carrying the program identifier and the playing visual angle parameter to a server;

it is to be understood that the playing view parameter may include one of the view parameters playable by the user in the target program, and may also include a default view parameter when not selected by the user, that is, a set view parameter (e.g., a main view parameter). The playing view angle parameter is determined by a video recording terminal, that is, at least one video recording terminal is adopted to record in a recording site of a target program, each video recording terminal adopts one recording view angle parameter, and the recording view angle parameter is the playing view angle parameter after being sent to the video playing terminal. For example, as shown in fig. 3, a target program recording site includes 7 video recording terminals (cameras), and each camera has one recording view angle parameter, that is, there are 7 selectable playing view angle parameters for the target program, where the recording view angle parameter corresponding to the camera No. 4 located right in front of the 7 cameras can be used as the default view angle parameter.

In the specific implementation, when a user performs a touch operation on a video playing interface of the video playing terminal, inputs voice information through a receiver of the video playing terminal, inputs gesture actions through a camera of the video playing terminal, and the like, the video playing terminal identifies the received operation and identifies the operation as a three-dimensional video playing signal for a target program, analyzes the signal, extracts information such as a playing view angle parameter carried by the signal and a program identifier of the target program, generates a video acquisition request based on the extracted information, and sends the generated request to a server. The three-dimensional video playing signal can be a three-dimensional video live broadcasting signal and can also be a three-dimensional video recording and playing signal. It should be noted that the video playing terminal can simultaneously support a 3D playing mode and a 2D playing mode, and in a feasible implementation manner, the acquired three-dimensional video playing signal is determined by selecting a touch key of the 3D playing mode.

S202, the server receives the video acquisition request, acquires the program identification and the playing view angle parameter in the video acquisition request, and receives a recorded video data set corresponding to the program identification acquired by a video recording terminal in real time;

it can be understood that the video recording terminal collects and records video data in real time at a program recording site, and sends the collected data to the server for storage in real time. That is, the recorded video data is live data.

In the specific implementation, after receiving a video acquisition request sent by a video playing terminal, a server analyzes the request, extracts a program identifier and a playing view angle parameter carried by the request, and searches a recorded video data set corresponding to the program identifier in the received recorded video data, or requests a real-time recorded video data set from the video recording terminal corresponding to the program identifier.

For example, if the target program is identified as "news simulcast", the server searches for live data of "news simulcast" from the received multiple live video data, or directly requests the live data from the video recording terminal of "news simulcast".

S203, the server acquires recording visual angle parameters corresponding to each recording video data in the recording video data set to generate a recording visual angle parameter set;

for example, the recording view parameters corresponding to cameras No. 1, 2, 3 …, and 7 shown in fig. 3 are a1, a2, A3, …, and a7, respectively, and then the recording view parameter set includes these 7 recording view parameters. It should be noted that each recording view parameter corresponds to a camera identifier. The camera identification may include a camera model, number, LOGO, etc.

S204, the server sends the recording view angle parameter set to the video playing terminal;

s205, the video playing terminal receives and displays the recording visual angle parameter set;

it can be understood that, the video playing terminal may display each recording view parameter in the received recording view parameter set by using a set display rule, so that the user may select a view to be watched from the displayed recording view parameters. As shown in tabular form.

S206, the server acquires a first recording visual angle parameter matched with the playing visual angle parameter and a second recording visual angle parameter which is adjacent to the first recording visual angle parameter left and right from the recording visual angle parameter set;

in the specific implementation, the server traverses each recording view parameter in the recording view parameter set, matches the currently traversed recording view parameter with the playing view parameter, if the matching is successful, the currently traversed recording view parameter is used as a first recording view parameter, if the matching is failed, the next recording view parameter is continuously traversed, and the matching is performed again until the successfully matched recording view parameter is found. And meanwhile, taking the recording visual angle parameters adjacent to the left and right sides of the first recording visual angle parameter as second recording visual angle parameters. For example, as shown in fig. 3, if the selected playing angle of view parameter is a2 angle corresponding to camera No. 2, then the recording angle of view parameters a1 and A3 corresponding to camera No. 1 and camera No. 3 are used as the second recording angle of view parameter.

The server can analyze each recording visual angle parameter in the recording visual angle parameter set so as to match left and right adjacent visual angle parameters of the current visual angle parameter, and cache the parameters, so that the parameters can be quickly acquired in the cache when searching for the second recording visual angle parameter.

For example, for the cameras in fig. 3, by analyzing the view angle parameter of each camera, the position relationship of the recording view angle parameters shown in table 1 may be matched, where the current view angle parameter corresponds to the first recording view angle parameter, and the left view angle parameter and the right view angle parameter correspond to the second recording view angle parameter.

TABLE 1

Current view angle parameter	Left side view angle parameter	Right side view angle parameter
			A1	A2	Is free of
A2	A3	A1
			A3	A4	A2
A4	A5	A3
			A5	A6	A4
A6	A7	A5
			A7	Is free of	A6

S207, the server acquires target recorded video data corresponding to the first recorded view angle parameter and the second recorded view angle parameter from the recorded video data set, and the target recorded video data is used as playing video data;

it can be understood that, since the recorded video data corresponds to the recorded view angle parameters one to one, the corresponding recorded video data, i.e., the played video data, can be quickly acquired based on the found first recorded view angle parameter and the second recorded view angle parameter.

In an optional embodiment, as shown in fig. 4, after the server receives a recorded video data set corresponding to the program identifier collected by the video recording terminal in real time, the method further includes:

s301, the server converts the recorded video data set into a code stream data set for storage;

it can be understood that converting the recorded video data set into the stream data set means converting the video stream that has been compressed and encoded into another video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user requirements. Transcoding is essentially a process of decoding first and then encoding, so the code stream before and after conversion may or may not conform to the same video encoding standard. As shown in fig. 3, after the recorded video data is received by the server, the recorded video data is stored in the database DB by video transcoding.

The server selects the playing video data corresponding to the playing view angle parameter from the recorded video data set, and the method comprises the following steps:

s302, the server selects the playing code stream data corresponding to the playing view angle parameter from the code stream data set.

It can be understood that after the recorded video data is transcoded and stored, the video source is changed into a code stream data set of another form, and then the code stream data corresponding to the first recording view angle parameter and the second recording view angle parameter is searched in the code stream data set, and the searched code stream data is used as playing code stream data.

S208, the server carries out three-dimensional synthesis processing on the played video data, acquires a first storage address of the played video data after the three-dimensional synthesis processing, and sends the first storage address to the video playing terminal;

S209, the video playing terminal plays the played video data after the three-dimensional synthesis processing based on the first storage address.

S210, when the video playing terminal detects a view angle parameter switching signal input aiming at the recording view angle parameter set, the video playing terminal acquires a view angle switching parameter carried by the view angle parameter switching signal and sends a video switching request carrying the view angle switching parameter to the server;

it can be understood that the view switching parameter refers to one view parameter selected from a set of recording view parameters which can be played by a user on a display interface and are specific to a target interface, if the view switching parameter is the same as a playing view, a target program is continuously played at a current view, and if the view switching parameter is different from the playing view parameter, a view parameter switching signal is generated.
