Edge blending processing and control system and edge blending processing and control method for playing videos

Abstract

The invention discloses an edge blending processing and control system for playing videos, which comprises a preblending configuration manager and at least two blending configuration and playing terminals; the blending configuration and playing terminals are respectively connected with the preblending configuration manager; the preblending configuration manager is used for controlling the blending configuration and playing terminals to adjust blending configuration parameters, collecting blending configuration parameters from the blending configuration and playing terminals, carrying out edge blending processing on videos to be played according to the blending configuration parameters to form video image information, segmenting the video image information and respectively sending the video image information to the corresponding blending configuration and playing terminals; the blending configuration and playing terminals synchronously decode the received video image information, and play the video image information. The invention does not have special requirements on the size and shape of a projection screen, the cost is low, multiple channels of videos can be synchronously played, and the invention is particularly suitable for edge blending application scenarios for playing videos.

Description

technical field [0001] The invention belongs to the technical field of image data processing, and in particular relates to an edge fusion processing and control system and method for playing video. Background technique [0002] The application of edge fusion comes from the military simulation / stereo theater system. Through software or dedicated hardware, a large-scale, high-resolution picture is divided, deformed, and displayed by multiple display devices after adding a fusion belt. These display devices can work together to restore this large-size, high-resolution picture (for example, multiple projectors can be used to jointly project and splice a large-size, high-resolution picture that cannot be projected by a single projector). The pursuit of bright super-large screens, pure colors, and high-resolution display effects has always been a potential requirement for people's visual experience. From the establishment of command and monitoring center and network management ce...

AI Technical Summary

Problems solved by technology

Among the three methods, the software technology has many adjustable parameters, the single-frame display effect is good, and the cost is the lowest. However, due to the limitations of the operating system and graphics card driver, it is impossible to perform fusion calculations for certain display images, real-time performance cannot be guaranteed, and refresh efficiency is average. Low, often screen tearing and other issues

The above-mentioned technical solutions for real-time fusion computing still have many deficiencies in terms of cost and effect. For example, the existing fusion system cannot independently solve the problem of synchronous playback of ultra-high-resolution video, and is limited by a single fusion device. In the process of video fusion, fusion devices need to use video synchronization playback software to synchronize

At the same time, existing systems inevitably need to rely on other video decoding devices, such as ordinary computers, when performing video playback tasks, so that the system cost in video fusion application scenarios cannot be minimized

[0005] In order to overcome the defects of high cost of the above-mentioned devices in the prior art, no integrated video decoding device, and inability to efficiently process ultra-high-resolution video, an edge fusion processing and control system for playing video and its processing and control method are proposed. At a lower cost than all current technical solutions, it achieves the same or better fusion playback effect of hardware real-time fusion equipment
