While streaming has dominated modern home media, a massive community dedicated to retro gaming (PS2/Xbox diagnostics) and high-end home audio (SACD and vintage DVD-Audio players) relies heavily on these discs.

These discs contain specific digital patterns to optimize the output of the player to a display or amplifier: sony dvd test disc
