Sorry Boac I've had to google smartlink to find out what it was.
The answer is that smartlink is a propriatry name for Sony systems, JVC appears to have the same thing but calls it TV-link, so yes it does.
Other companies call it by different names, Panasonic = Q-link, Grundig = Megalogic, Philips=Easy-link, Metz + Data-logic. All very confusing.
