Embodiment Construction
[0015] The specific implementation of the video signal display method and system of the present invention will be described in detail below with reference to the accompanying drawings.
[0016] refer to figure 1 , figure 1 Shown is a flow chart of a video signal display method in one embodiment, including the following steps:
[0017] S10, receiving a pause control instruction of the video signal, updating the pause control instruction in the system at the beginning of each frame of the video signal, and performing a pause operation on the video signal according to the updated pause control instruction;
[0018] In the above step S10, the system that receives the pause control command of the video signal and performs related update and pause operations is the video control system. Above-mentioned video control system can be some kind of intelligent processing system, such as FPGA control system; Above-mentioned video control system is in the process of displaying video signa...

The present invention relates to a video signal display method and system, wherein the video signal display method includes: receiving the pause control instruction of the video signal, updating the pause control instruction in the system at the beginning of each frame of the video signal, and according to the updated The pause control command performs pause operation on the video signal; after updating the pause control command, continue to receive the currently paused video signal and start storing it, and after storing a complete frame of video signal, turn off the system’s default repeat storage operation function; During the pause process, the stored video signal is displayed; the video signal in the pause only needs to be stored once, and there is no need to continuously store the video signal that needs to be paused; the bandwidth utilization rate of the video control system can be improved, and high bandwidth usage can be reduced. The instability brought by its storage system, and then improve the stability of the corresponding video control system.
Description
technical field [0001] The invention relates to the technical field of signal processing, in particular to a video signal display method and system. Background technique [0002] In various environments that require video display, such as consumer electronics, municipal administration, transportation, and military industry, the scale of signals required to be processed is getting larger and larger, and the requirements for the types and quality of signal processing functions are also getting higher and higher. The technology of displaying the paused video signal will often appear in the above application environments. The processing of the paused video signal in the prior art generally needs to be repeatedly stored and read and written, which leads to the occupation of the paused video signal when processing the paused video signal. The video storage system has too much bandwidth, which reduces resource utilization and affects system stability. Contents of the invention ...
