Abstract

The invention relates to a video overlay device and method. The video overlay device includes a first dynamic video signal storage module for storing a dynamic video signal and transmitting the dynamic video signal to a storage control module; the storage control module for controlling the real-time storage of the dynamic video signal and transmitting the dynamic video signal to a second dynamic video signal storage module; the second dynamic video signal storage module for storing the dynamic video signal and transmitting the dynamic video signal to a video overlay module; a local video signal storage module for storing a local video signal and transmitting the local video signal to a video overlay module; the video overlay module for overlaying the dynamic video signal and the local video signal and transmitting the overlaid video signal to a display module; and the display module for receiving the overlaid video signal transmitted by the video overlay module and displaying the overlaid video signal.

Description

technical field [0001] The invention relates to the field of video image processing, in particular to a video overlay device and method. Background technique [0002] With the development of computer technology, the application of video image processing technology is becoming more and more extensive. Among them, video overlay technology is an important research and development direction in image video processing. Through video overlay technology, characters or image signals can be superimposed on video signals. The specific position of the screen is displayed simultaneously with the video signal, so that people can obtain multiple effective information at the same time. [0003] The large amount of processing data and the real-time nature of the processing process are important characteristics of video image processing. Real-time means that the transmission and processing of image and video data are carried out continuously at a certain speed. In order to ensure the continu...
