30 line television transmission

A 30-line television transmission refers to a method of broadcasting images using 30 horizontal lines drawn sequentially to create a complete picture. Each line captures a portion of the image, and these are transmitted rapidly in succession—about 30 times per second—to produce a stable, moving picture on-screen. This process involves converting visual information into electrical signals, which are then sent over the transmission medium (like air or cable). When received, the device reconstructs the lines into a cohesive image. Although this technique was common early on, modern broadcasts use higher resolution systems for clearer images.
