Problems solved by technology

However, on the one hand, the clarity of the recording using this software is not enough, on the other hand, it takes up the system resources of the host computer and causes the phenomenon of "stuck" during recording, which is a serious problem for video recorders, especially gamers
[0007] Although the existing HDMI display can realize the function of high-definition display, the function is relatively single, and the above-mentioned recording problem cannot be solved on the hardware

Abstract

The invention discloses display equipment with high-performance picture recording. The display equipment comprises an HDMI (High-Definition Multimedia Interface) input interface, an HDMI data buffer zone, a dual-channel output module, a display circuit of a display, an audio and video processing module, a storage module, an MCU (Microprogrammed Control Unit) controller and a picture recording switch, wherein the HDMI input interface is used for receiving an HDMI signal input from exterior; the HDMI data buffer zone is used for buffering the HDMI signal; the dual-channel output module is used for identifying the buffered HDMI signal; the MCU controller is used for controlling output of the signal of the dual-channel output module according to the on-off state of the picture recording switch; the audio and video processing module is used for integrating the HDMI signal to audio and video data. The invention further discloses a picture recording method based on the display equipment with high-performance picture recording. According to the technical scheme provided by the invention, a picture recording process does not rely on software and system resources of a host, so that the blocking phenomenon is avoided, and normal display of a video cannot be influenced.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a display equipment with high-performance video recording. Background technique [0002] The input interfaces of existing displays mainly include VGA (Video Graphics Adapter, Video Graphics Array) interface, DVI (Digital Visual Interface, Digital Video Interface) and HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface). [0003] VGA interface is the most widely used interface type on graphics cards. Most graphics cards have this interface, but because the input is analog signals, it will inevitably cause some loss of image details. It is only suitable for video cards below 20 inches. The use of monitors has been gradually replaced by DVI interface and HDMI input interface in display devices that require high-definition display. [0004] Compared with the traditional VGA signal, the DVI interface has no phase problem in the liquid crystal display usin...
