During video playback, the video quality determines the user's audiovisual satisfaction. According to the requirements of real-time video transmission under different conditions, the video quality can be divided into 5 grades. They are high-definition video conferencing (HDTV), studio-quality digital TV, broadcast-quality TV, VCR-quality TV, and videoconferencing quality.
