Abstract

The invention discloses a digital video acquisition card. The digital video acquisition card comprises a high-speed A / D (analog-to-digital) converter, a data interacting unit, a digital signal processor and a peripheral component interconnect (PCI) bridge, wherein the input end of the high-speed A / D converter is connected to an exterior analog video signal generation end, while the output end of the high-speed A / D converter is connected to the data interacting unit; the output end of the data interacting unit is connected to the digital signal processor; the PCI bridge is connected to the digital signal processor through a PCI bridge adhesion logical unit; and the digital signal processor is also connected with a communication state detection module. The digital video acquisition card has the beneficial effects that the digital video acquisition is achieved while the function of independent real-time digital video processing is also realized.

Description

technical field [0001] The invention relates to a digital video acquisition card. Background technique [0002] Video capture card, "Video Capture Card", its function is to capture video signals into the computer and save them on the hard disk in the form of data files. It is an indispensable hardware device for our video processing. Through it, we can transfer the video signal captured by the camera from the video tape to the computer, and use the relevant video editing software to edit the digital video signal. Processing, such as cutting pictures, adding filters, subtitles and sound effects, setting transition effects, adding various video special effects, etc., and finally converting the edited video signal into standard VCD, DVD and online streaming media formats, which is convenient spread [0003] According to the video signal source, video capture cards can be divided into digital capture cards (using digital interface) and analog capture cards. Traditional digita...
