Basic knowledge of digital video

Digital video refers to the electronic format used for capturing, processing, and transmitting a series of images to create the illusion of motion.

Definition of digital video

Digital video refers to the electronic medium that captures, encodes, and reproduces motion by sequentially processing a series of still images as electrical signals.

Characteristics of digital video

Digital video technology offers several advantages over analog video, including convenient storage, superior image quality, ease of editing, and the ability to provide a range of new services.

Principle of visual retention in digital video

The phenomenon of visual retention, where the human eye retains an image for approximately one-tenth of a second, allows digital video to create the perception of continuous motion from a series of discrete images.

Processing of digital video

Digital video processing is founded on digital image processing techniques, treating each frame of video as a standalone image. This processing can leverage the correlation between successive frames to enhance video quality and perform various transformations.

Applications and evolution of digital video

Originally developed for television systems, digital video technology has expanded into multiple formats, facilitating consumer recording and enabling the distribution of video content over the internet as streaming media.

In summary, digital video technology represents a significant advancement in the field of digital media, providing a robust framework for the capture, manipulation, and dissemination of moving visual content.
