The present disclosure provides a method for determining a recommended video, a data processing computer server and a system. The computer server determines candidate virtual scenes, users currently participating in the candidate virtual scenes, and a user corresponding to a virtual role in the candidate virtual scenes. After selecting a target virtual scene from the candidate virtual scenes, the computer server determines representation data of virtual roles of the target virtual scene, selects a target virtual role from the virtual roles of the target virtual scene according to the representation data of the virtual roles of the target virtual scene, and generates a recommended video at a viewing angle of the target virtual role in the target virtual scene.

The present invention discloses an invisible word proposing projector system and a video data processing method. The system comprises a light source, a first convergence mirror, a color wheel, a second convergence mirror, a digital micro-mirror, a digital micro-mirror driving module and a lens, and further comprises a frame synchronization signal transmitting module, liquid crystal glasses, a subtitle data generation module, a video data generation module and a subtitle superposition module. The video data is processed through a subtitle superposition module, the processed video data is projected to a lens by a digital micromirror, and a projection area is formed on an imaging plane; after the liquid crystal glasses are worn, hidden subtitles can be observed on an imaging plane, audienceswithout liquid crystal glasses cannot observe the hidden subtitles on the imaging plane, the projection effect of the video data on the imaging plane under the view angle of the audiences is the sameas that through a common projector; and the design is reasonable, the use is convenient, the projector can be used as a common projector, the function of giving words to a speaker can be realized, andthe watching of the audience is not influenced.

A controller controls multiple camera modules, and processes video images captured by the multiple camera modules. The controller is configured: (i) to output a frame synchronization signal FSYNC to each of the multiple camera modules; (ii) to receive frame data and a transmission synchronization signal SYNC that is synchronized with the frame data; (iii) to process the multiple items of frame data thus received; and (iv) to acquire a time difference between the corresponding frame synchronization signal and the corresponding transmission synchronization signal for each camera module, so as to adjust the timing of the frame synchronization signal according to the time difference.

The invention discloses a synchronization method, device, device and system for improving video data stream frames. According to the size of the video frame, a buffer space is adaptively applied; when the current frame data transmission ends, a first end interrupt signal INT1 is generated; Once the current frame data transmission in the interrupt signal INT1 ends, the interrupt is terminated, and the current frame data is obtained from the corresponding buffer area. After image algorithm processing is performed on the current frame data, the processing result is transmitted to the buffer area, and the transmission of the pending result is completed. The current frame result is generated, and the second end interrupt signal INT2 is transmitted; the transmission completion interrupt is completed according to the processing result, and the time difference Tp between the first end interrupt signals INT1 and INT2 is calculated, and linear segmentation processing is performed according to the size of the time difference Tp. The invention can adaptively improve the video data frame and improve the frame synchronization output precision.
