And anyway. The "non-pixel path" doesn't sound like a piece of hardware
to me (nor did it to Krzysztof, [1]). It is just a port through which
the data is being transferred. The encoder acquires pixel data through a
pixel port, processes it and returns it back through a non-pixel port
and vice versa for the decoder.
