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 large-screen scene picture splicing display method, 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 including the length and width of the small screen;

[0046] S2: Select a 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 package sent to each server, and record the sending time point t 1 ;

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

[0049] S5: Calculate the response value F of each player 1 , f video adoption rate, the player whose response value is greater than the threshold is elimin...

Embodiment 2

[0055] Embodiment 2 of the present invention provides a large-screen scene picture splicing display method, which is basically the same as Embodiment 1, the difference is that, as figure 2 As shown, splitting the large-screen scene picture into multiple small-screen scene pictures specifically includes:

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

[0057] S12: Perform secondary splitting on the moving target and the background image respectively to form multiple small-screen scene images.

[0058] Step S12 is further defined, for details, refer to image 3 .

[0059] S121: First separate a sub-block from the moving target or the 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 calculate the intra-block de...

Embodiment 3

[0066] Embodiment 3 of the present invention provides a large-screen scene picture splicing display method, which is basically the same as Embodiment 2, the difference is that, as Figure 4 As shown, sending the small screen scene 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 scene pictures split by the moving object to the player, and then send the data corresponding to the small-screen scene pictures 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 to ensure better synchronous playback of moving target images.

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 in particular relates to a method for splicing and displaying scenes on a large screen. Background technique [0002] The scene image playback system in the large-screen industry usually adopts a single-screen playback mode, and for high-resolution scene images, the large-screen playback system needs to use a large screen with high performance and high resolution for playback, which brings great impact to the large-screen playback system. A big problem. 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 The acquisition of parameters, the display of large-screen scene images and other steps realize the split-screen rendering of the same scene ima...
