An airborne video real-time mixed display system

Abstract

The invention discloses an airborne system for mixing and displaying videos in real time. The airborne system comprises an instruction exchange area, a video conversion / decoding module, a frame storage device, a video controller and a power module. The invention relates to the field of video processing and is a specific airborne video real-time mixing technology and an image displaying system framework. The video controller is a core of the whole system and is in charge of communicating with an upper computer, configuring a decoding chip, amplifying video pictures, controlling the frame storage device, controlling input / output videos and driving display and the like. The airborne system disclosed by the invention has the advantages that the video decoding chip can be automatically configured, the dynamic switching of multi-path background video input and real-time amplification of background video pictures are realized, and the inputted foreground and background are mixed and displayed according to parameters provided by the upper computer. Compared with the prior art, the airborne system disclosed by the invention has the characteristics of high real-time performance, small volume, low power consumption, high picture refreshing rate and good video mixing effect and the like.

Description

technical field [0001] The invention relates to an airborne video real-time mixed display system, which belongs to the technical field of video processing. Background technique [0002] With the rapid development of microelectronics technology, the technical level of the airborne cockpit display system is advancing by leaps and bounds. The airborne cockpit display system is an important way for the pilot to interact with the aircraft in real time, and it is the main means for the pilot to understand the status of the aircraft and the flight environment. There are usually multiple video sources in the cockpit integrated system for pilots to read information, and the video images generated by other graphics generation systems or cameras are usually presented on different displays, but the dispersion of information presentation will inevitably lead to increased burden on pilots. The signal formats provided by different video signal sources will be different, and the video reso...

Problems solved by technology

In the airborne cockpit integrated system, there are usually multiple video sources for the pilot to read information, and the video images generated by other graphics generation systems or cameras are usually presented on different displays, but the dispersion of information presentation will inevitably lead to increased burden on the pilot

The signal formats provided by different video signal sources will be different, and the video resolution and frame rate may be different. These factors mean that the simple video mixing method cannot meet the video mixing requirements of the airborne cockpit display system
