I think you have got electronically generated ultrasonic mixed up with RF remotes (which I've never heard of being used with TV).
All RCA remotes up through the 60's that I know of are ultrasonic...Electronically generated ultrasonic (switched transistor oscilator driving a small ultrasonic tweeter), but definitely ultrasonic.
