Having a cheap ST chip in a set top box is one thing.

Having a parallel computer architecture, upon which a new OS (Helios) and paradigm was to be based was the goal. The UK failed to fund this and the vision failed.

Most of the set top boxes with the ST chip in them are the cheap, poor performing ones. The better ones have a Pallas/Vulcan PowerPC chip in them. Alas, IBM messed up and they have not kept up in this space.
