That ad is a nice trip down memory lane. One of RCA's mistakes was not seeing the need for stereo sound (let alone video and audio jacks) until a couple years into the format. (They once did a promotion where if you bought a stereo player and an RCA big screen set, you got Star Wars for free!) They even managed to make a player with LD-esque interactive features but the format was already doomed by then. Return of the Jedi was among the last batch of titles ever made for CED. So rare, some early SW collectible price guides didn't even know it existed.
