Baird's 30-line television system

Baird's 30-line television system, developed by John Logie Baird in the 1920s, was an early experimental television format with only 30 horizontal lines of resolution. This low number meant the images were very basic and pixelated compared to modern standards. The system used mechanical scanning, where a spinning disk with holes rapidly moved to scan an image line by line and reproduce moving pictures. While limited in quality, it was a significant step in developing television technology, demonstrating the potential of transmitting live moving images wirelessly and laying groundwork for later electronic television systems with higher resolution.
