Abstract

The invention discloses a screen splicing system and a video data stream processing method. The system includes: a video acquisition subsystem, configured to acquire an original video data stream, and output the acquired original video data stream to a smooth displaying subsystem after a smooth displaying image processing mode is enabled; the smooth displaying subsystem, connected with the video acquisition subsystem and configured to receive the original video data stream from the video acquisition subsystem, sequentially perform smooth displaying image processing and screen cutting processing on the original video data stream and send the cut video data stream to a screen splicing subsystem; and the screen splicing subsystem, connected with the smooth displaying subsystem and configured to perform splicing processing on the cut video data stream and send the spliced video data stream to a splicing display wall. According to the technical solutions provided by the invention, screen splicing display smoothness is improved, and an overall display effect of the screen splicing system is remarkably improved.

Description

technical field [0001] The invention relates to the field of video display, in particular to a screen splicing system and a processing method for video data streams. Background technique [0002] At present, the typical screen splicing system used in related technologies (using multiple display splicing display methods to realize the display function of a single screen) can support screen splicing and roaming of analog video signals, digital video signals, network compressed code streams, etc. show. figure 1 It is a schematic diagram of the realization principle of the screen splicing system according to the related technology. like figure 1 As shown, the screen splicing system may include: a video acquisition subsystem (specifically, it can be divided into an encoding subsystem and a decoding subsystem) and a screen splicing subsystem. Each subsystem can interact with each other through a high-speed peripheral device interconnection bus (PCI Express, referred to as PCIe)...
