What is another word for mechanical television?
Pronunciation: [mɪkˈanɪkə͡l tˈɛlɪvˌɪʒən] (IPA) 
The term "mechanical television" refers to a type of television that relies on mechanical methods to capture and display images. There are several synonyms for this type of television, including rotating-disc television, mechanical scanning television, and Nipkow disk television. The key feature of such television is the use of a spinning disc with a series of holes or slits which scans the image into a series of lines, and then reconstructed into a frame. While this technology was the first to be commercially available, it has largely been replaced by electronic televisions which are more efficient and superior in picture resolution.
