The unique equipment of the multimedia computer is the video card, which is used to input the video data or the mixed data of video and audio output from analog cameras, video recorders, LD video players and video signals from TV sets into the computer, and convert them into digital data that can be identified by the computer, which is stored in the computer and becomes a video data file that can be edited and processed.

The unique equipment of multimedia computer is video card.

Related introduction:

Video capture card (Video Capture card), also known as video card, is used to input video data or mixed data of video and audio output from analog cameras, video recorders, LD video players and TV sets into computers, and convert them into computer-recognizable digital data, which are stored in the computer and become video data files that can be edited and processed. According to its use, it can be divided into broadcast grade video capture card, professional grade video capture card and civilian grade video capture card.

Principle

Video capture card, also known as video capture card, can be used to obtain digital video information, store and play it. Many video capture cards can capture the video information and obtain the accompanying sound at the same time, so that the audio part and the video part can be saved and played synchronously when digitizing.

Video capture card, "Video Capture Card", its function is to collect the video signal to the computer and save it on the hard disk in the form of data file. It is an indispensable hardware equipment for video processing, through it to carry out post-editing processing of the digital video signal, such as cutting the picture, adding filter ytterbium, subtitles and sound effects, setting transition effects and adding a variety of video special effects and so on. Finally, the edited video signal is converted into standard VCD, DVD and online streaming media format to facilitate transmission.

Multi-frame images produce a sense of motion with time, so video is also called moving image. According to the different storage and processing methods of video, it can be divided into analog video and digital video.

Video acquisition is the process of converting the analog signals of the video source into digital signals (i.e. 0 and 1) through processing, and storing these digital information on the computer hard disk. This analog / digital conversion is carried out through the acquisition chip on the video capture card.
