In the 1950s, TVs were set up by professionals. By the 1970s, people tuned their own TVs. In the 1990s, component video arrived, and a calibration disc was released. Now, with digital video, we have Digital Video Essentials. This disc helps with system setup, considering it a canvas for electronic art. It includes NTSC, PAL, and HDTV versions with unified instructions and test patterns. It covers the environment, audio, and video setup, making it the modern "TV Guy".
Digital Video Essentials
The evolution of television tuning spanned several decades, from the 1950s "TV GUY" who brought and tuned sets for viewers, to the 1970s "plug and play" era where viewers took on the task, and ultimately, the 1990s introduction of component video into the home.
