Problems solved by technology

In order to solve the problems existing in the prior art, CN104125494 discloses a large-screen distributed play scene picture splicing method, the method binds the scene picture data, establishes a corresponding model between the player and the small screen, and the player corresponds to the small screen Steps such as the acquisition of parameters and the display of large-screen scene images realize the split-screen rendering of the same scene image by using multiple players. Each player is responsible for a specific scene area, and the entire scene image is displayed on the large screen through multiple players. The display above overcomes the performance bottleneck defect of a single player under the high-resolution scene picture, but the mosaic display method disclosed in the prior art, because there are multiple players, the performance and bandwidth of the multiple players are not the same , so there is a problem that multiple players cannot achieve synchronous playback

Embodiment 1

[0044] Embodiment 1 of the present invention provides a method for splicing and displaying large-screen scenes, such as figure 1 As shown, the method includes the following steps:

[0045] S1: Split the large screen scene picture into multiple small screen scene pictures, establish a small screen model, and record the parameters of each small screen model, the parameters include the length and width of the small screen;

[0046] S2: Select the player corresponding to the small screen model according to the parameters of each small screen model;

[0047] S3: Send a link request to the selected player, the link request includes the test packet sent to each server, and record the sending time t 1 ;

[0048] S4: Receive the reply data packet sent by each player, and record the receiving reply time point t 2 ;

[0049] S5: Calculate the response value F of each player 1 , f Video adoption rate, remove players whose response value is greater than the threshold; at the same time, reselect the...

Embodiment 2

[0055] Embodiment 2 of the present invention provides a method for splicing and displaying large-screen scenes. The method is basically the same as that of Embodiment 1, except that: figure 2 As shown, splitting a large-screen scene into multiple small-screen scenes specifically includes:

[0056] S11: Split the large screen scene for the first time according to the moving target and background image;

[0057] S12: Separate the moving target and the background image twice to form multiple small screen scenes.

[0058] To further limit step S12, refer to image 3 .

[0059] S121: First separate a sub-block from the moving target or background image, and calculate the intra-block deviation X of the sub-block;

[0060] S122: Based on the sub-block, transform the length and / or width of the sub-block to obtain n sub-blocks with different lengths and widths, and then respectively calculate the intra-block deviations X1, X2...Xn of the n sub-blocks;

[0061] S123: Find a sub-block correspondin...

Embodiment 3

[0066] Embodiment 3 of the present invention provides a method for splicing and displaying large-screen scenes. The method is basically the same as that of Embodiment 2, except that: Figure 4 As shown, sending the small screen scene picture data to the corresponding player specifically includes:

[0067] S61: Sort the players according to the response value from small to large;

[0068] S62: Starting from the first sorting, sequentially send the data corresponding to the small screen scenes separated by the moving target to the player, and then send the data corresponding to the small screen scenes separated from the background image.

[0069] The present invention further selects the small screen scene picture to be played according to the response speed of each player, which can ensure better synchronized playing of the moving target image.

Abstract

The invention provides a large screen scene frame splicing and displaying method. The large screen scene frame splicing and displaying method comprises the steps that a large screen scene frame is split into multiple small screen scene frames, players are selected, preliminary screening is conducted on processing time and response time of the players, the players short in response time and low intransmission speed are removed, then players are selected for small screen models again, corresponding relation between the players meeting primary detecting standards and the small screen models is established, data corresponding to the small screen scene frames is sent to the corresponding players, corresponding play identifiers are sent, playing sub-zones and putting representations corresponding to play representations are set on the large screen scene frame, and then putting time points are set for the players by a server. It is ensured that all the players synchronously play put small screen scene frames, and the problem of putting delay caused by different response times of the players themselves is solved.

Description

Technical field [0001] The invention belongs to the field of video display, and particularly relates to a large-screen scene picture splicing display method. Background technique [0002] The scene picture playback system in the large-screen industry usually adopts a single-screen playback mode. For high-resolution scene pictures, the large-screen playback system needs to use a large screen with high performance and high resolution for playback, which brings to the large-screen playback system A big problem. In order to solve the problems in the prior art, CN104125494 discloses a large-screen distributed playback scene picture splicing method. This method binds scene picture data to establish a model corresponding to the player and the small screen, and the player corresponds to the small screen. The steps of obtaining parameters and displaying large-screen scenes realize the split-screen rendering of the same scene with multiple players. Each player is responsible for a specifi...
