Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the display method of video dynamic identification information provided by the present invention includes the following steps:

[0022] In step S101, the FPGA chip provides the read operation timing and address pointer of the flash memory, and reads the video dynamic logo frame data from the flash memory and stores it.

[0023] Wherein, the step of the FPGA chip storing the video dynamic identification frame data may be: the FPGA chip generates a RAM space inside; the video dynamic identification frame data read from the flash memory is cached in the RAM space. T...

Abstract

The invention discloses a display method and a display system for video dynamic identification information. The method comprises the following steps that: a field programmable gate array (FPGA) chip reads video dynamic identification frame data from a flash memory, and stores the video dynamic identification frame data; two memory areas are created in a first in first out data cache, and the FPGA chip writes the video dynamic identification frame data into the two memory areas for caching, and reads the video dynamic identification frame data from the two memory areas in a ping pong operation way; and the FPGA chip synthesizes the video dynamic identification frame data read from the two memory areas into a video signal received by the FPGA chip, and outputs the video signal. According to the display method for the video dynamic identification information, the FPGA chip displays the dynamic identification information in a video, and compared with the prior art, the invention solves the problems of long development cycle and high hardware cost caused by a digital signal processor (DSP); and in addition, the method can be simply implemented, and labor cost in research and development processes is saved.

Description

technical field [0001] The invention belongs to the technical field of video signal processing, and in particular relates to a display method and system for video dynamic identification information. Background technique [0002] Today's TV programs broadcast a variety of screens. While displaying video images, it is usually necessary to display dynamic video identification information such as station logos, time, TV theater logos, and advertising icons. These information usually need continuous scrolling in real time. For this reason, the prior art adopts DSP plus flash memory to realize this purpose. Through the powerful graphics processing function of DSP, the video dynamic identification information continuously displayed on the video is realized. [0003] Although this method can complete the display of video dynamic identification information very well, its development process is cumbersome, and because DSP is a special chip, it needs special personnel and professional ...
