What is defined as a series of images broken down into lines in video technology?

1. Digital Video

2. Analog Video

3. Motion Video

4. Static Video

The correct answer is: Analog Video

The concept described in the question refers to how video data is structured and transmitted. Analog video is characterized by its method of representing images as a continuous electromagnetic signal, where the video is transmitted as a series of images that are broken down into horizontal lines (scan lines). This technique is prominent in traditional broadcast formats and older video recording systems, where the continuous signal allows for the display of motion and detail. In contrast, digital video involves encoding images into binary data, which can then be processed and stored. While both digital and analog video can contain lines of resolution, the definition specifically highlights the continuous nature of image representation in analog technology. The other terms, such as motion video, generally refer to the quality or type of video based on movement and action, while static video pertains to still images, which do not fit the context of being "broken down into lines." Therefore, the correct choice is aligned with the fundamental principle of how analog video operates within the realm of video technology.
