Abstract

The embodiment of the invention discloses a digital mark display method, which comprises the following steps of: obtaining an output resolution in response to a received digital mark display instruction, calculating a drawing position of a digital mark in proportion according to the output resolution, and drawing the digital mark according to the drawing position to obtain a digital mark image; receiving a video input image; superposing the video input image and the digital marking image to obtain a video output image; and outputting the video output image to a display screen for displaying through a video output interface. The embodiment of the invention further discloses a digital indication display system. According to the embodiment of the invention, the problem that the size of an OSDdigital marking image is not coordinated with the size of a video image can be solved, the BOM cost is reduced, the production process is simplified, the development amount is reduced, and the systemstability is improved.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a digital signage display method and a digital signage display system. Background technique [0002] There are multiple video output interfaces of the video processor. When connecting to the display, in order to match the video output interface with the display and distinguish the bottom edge of the display when the output image is rotated, it is convenient for the on-site personnel to assemble the display according to the requirements. , it is necessary to display the corresponding sign on the display screen, so a digital sign display method of OSD (On-screen Display, on-screen menu display) is designed. [0003] Carry out the digital indication display of OSD in the prior art, need main control circuit, the network and USB (Universal Serial Bus, universal serial bus) that communicate with other equipment on hardware scheme, RAM (random access) that stores OSD digital i...
