디지털 영상
Digital video can be copied and reproduced with no degradation in quality. In contrast, when analog sources are copied, they experience generation loss. Digital video can be stored on digital media such as Blu-ray Disc, on computer data storage, or streamed over the Internet to end users who watch content on a desktop computer screen or a digital smart TV. Today, digital video content such as TV shows and movies also include a digital audio soundtrack.
