Embodiment Construction

[0026] figure 1 It is a schematic diagram of the principle of a full HD video processing device. V1 is full high-definition video before processing. The video comes from an external device. It is characterized by a resolution of 1920×1080 and a frame rate of 60Hz. V1 is input to video receiver R1, which is built in FPGA, and the output of video receiver R1 is RGB digital video with composite VESA timing. The output signal of video receiver R1 becomes the input of RGB-YUV video format converter C1, the input signal is composite VESA timing RGB digital video, the output of RGB-YUV video format converter C1 is 4:2:0 YUV digital Video stream. Video buffer B1 is used for buffering video resources in the entire device, the output video of RGB-YUV video format converter C1 enters into video buffer B1, and video processor P1 reads video data from video buffer B1 and performs corresponding The processed video is taken out by the YUV-RGB video format converter C2 and put into the vid...

Abstract

The invention provides a full-high-definition video processing device for processing a path of full-high-definition video, and aims to solve the problems of large bandwidth, high data rate, high computational burden and the like in full-high-definition video processing. The device comprises a video receiver, an RGB-YUV video format converter, a video buffer, a video processor, a YUV-RGB video format converter and a video transmitter, wherein the video receiver is used for converting a DVI (Digital Visual Interface) video signal into digital video data of an RGB format; the RGB-YUV video format converter is used for converting the digital video data of the RGB format into digital video data of a YUV format; the video buffer is used for storing digital video data to be processed and processed digital video data; the video processor is used for processing the digital video data in the video buffer; the YUV-RGB video format converter is used for converting the digital video data of the YUV format into the digital video data of the RGB format; and the video transmitter is used for converting the processed digital video data of the RGB format into the DVI video signal.

Description

Technical field: [0001] The invention belongs to the technical field of embedded computer video processing, and in particular relates to a full high-definition video processing device. Background technique: [0002] Full HD digital video has been widely used in video surveillance, video tracking and other fields in recent years because of its advantages such as high resolution and high frame rate. Full high-definition digital video overcomes a series of problems such as small coverage area, low image definition, and low video image utilization rate of traditional standard-definition video. However, the high resolution and high frame rate of full high-definition digital video have brought about extremely high data rates, which have caused certain difficulties in video processing. It puts forward higher requirements on the bandwidth and processing capability of the digital video processing device. [0003] There are two main types of traditional high-definition video process...
