How about a Signetics TDA8440 Video and Audio Switch IC.

It can switch two groups of two audio inputs and one group of two video
inputs.

That is, two "SPDT" audio switches and one "SPDT" video switch in effect.

The chip is described on page 11-46
 of the 1989 Signetics Linear Data Manual Volume 3 (the video manual).
