The invention is further illustrated below with reference to a specific embodiment:
the invention provides a method for playing videos in multiple screens, which comprises the following steps: 1. the mobile phone 1, the mobile phone 2 and the mobile phone 3 establish Bluetooth connection;
2. any one of the mobile phone 1, the mobile phone 2 and the mobile phone 3 receives a playing video signal and distributes the video to other mobile phones through wifi or hot spots;
3. obtaining the video playing area of each mobile phone according to the layout;
3.1 according to the preset layout, for example, 3 mobile phones can be horizontally spliced, and the playing area of each mobile phone is calculated according to the video resolution and the video direction;
the video is centered and aligned and the horizontal distance is calculated in highly equal proportion. For example, after three mobile phone screens are spliced, the horizontal pixel width is 1080+1080+1080, and the height pixel is 1920. If the video is 1600x960, the amplified video is 3200x 1920. The middle screen of the center playing is 1080, and the two screens are (3200-1080)/2-1060, so that the mobile phone 1 plays the contents of the amplified videos (0, 0) to (1060, 1920) from the area (20,0) to (1080,1920), the mobile phone 2 plays (1061, 0) to (2140, 1920), and the mobile phone 3 plays (2141, 0) to (3200, 1920);
4. distributing the playing time axis position of the video to other mobile phones according to the time axis position;
5. calculating the transmission delay time of a time axis position by counting the time delay of a Bluetooth distribution signal so as to ensure synchronous playing of a plurality of mobile phones;
5.1 the mobile phone 1 sends the signal to the mobile phone 2 through the Bluetooth when the current system time is accurate to millisecond (for example: 1 month 1 day 00:00:00.111 in 2022), and the time difference is positive 1.1 seconds when the mobile phone 2 compares the current time difference (for example: 1 month 1 day 00:00:01.211 in 2022). The mobile phone 2 sends the current time to the mobile phone 1 (for example, the time of the mobile phone 2 is 2022, 1 month, 1 day 00:00:01.311), and the current time of the mobile phone 1 is (for example, the time of the mobile phone 2, 1 month, 1 day 00:00:00.411), the time difference is minus 0.9 second. Because of the fact that
The first time of the mobile phone 1 (for example: 1/00: 00.111 in 2022) + the mobile phone time error + the transmission delay time is equal to the first time of the mobile phone 2 (for example: 1/00: 01.211 in 2022);
the second time of the mobile phone 2 (e.g. 1/00: 01.311/2022) -the mobile phone time error + the transmission delay time is the second time of the mobile phone 1 (e.g. 1/00: 00.411/2022);
the time error of the mobile phone is 1 second, and the transmission delay time is 0.1 second.
5.2 when the mobile phone 1 sets the dragged video to play to a certain time point (for example, 00:30:01), the mobile phone 2 starts playing from 00:30:01.1 seconds after receiving the instruction, so that the two mobile phones can be synchronized. The mobile phone 3 calculates the transmission delay time in a similar manner; therefore, synchronous playing of a plurality of handheld devices is ensured by transmitting the time delay.
Referring to fig. 2, the present invention provides a system for playing videos on multiple screens, where the system includes a bluetooth establishing module, a video signal sending module, a video playing area setting module, a video sharing module, and a video synchronization module;
the Bluetooth establishing module establishes Bluetooth connection for a plurality of handheld devices;
the video signal sending module distributes the video to the remaining handheld devices through wifi or hot spots at one time after receiving the played video signal through any one of the handheld devices;
the video playing area setting module is used for acquiring the video playing area of each handheld device according to a preset multi-screen playing layout;
the video sharing module distributes video playing time points to the remaining handheld devices according to the playing time corresponding to each frame of the video;
the video synchronization module obtains the transmission delay time of the time axis position by counting the delay time of the Bluetooth distribution signal, and ensures that a plurality of handheld devices are played synchronously by the transmission delay time.
Further, the video playing area setting module is further specifically implemented as follows: the preset multi-screen playing layout comprises: the method comprises the following steps of horizontally splicing a plurality of screen layouts, vertically splicing a plurality of screen layouts or vertically and horizontally splicing a plurality of screen layouts, and obtaining the playing area of each handheld device according to the video resolution and the video direction.
Further, the video synchronization module is further specifically implemented as follows: after the current system time is accurate to millisecond, obtaining the current system time as first time of a handheld device, sending a signal to a second handheld device through Bluetooth, obtaining the second first time of the handheld device after the second handheld device obtains a video signal, continuously obtaining the current system time after the video signal is obtained by the second handheld device as second time of the handheld device, sending the second time to the first handheld device, and obtaining the first second time of the handheld device after the first handheld device receives the second time; then the equation is established: the first time of the handheld device, the mobile phone time error and the transmission delay time are the first time of the handheld device; the second time of the handheld device, namely the mobile phone time error and the transmission delay time, is the first time of the handheld device; the time error and the transmission delay time of the mobile phone can be obtained through two equations, the first handheld device sets the time point for dragging the video to be played to any one time point, and the second handheld device carries out synchronous playing on the video according to the transmission delay time after receiving the instruction.
