Fulfillment of that mission, however, has been hindered by the limitations of analog transmission. That is about to change.
Digital technology is tailor-made for our educational mission.
With analog, there is only one channel on which to feature the best in television programming and educational services. We have more good programs to air than broadcast time. The coming digital compression technology will allow us to broadcast multiple program services with varied menus. We know that education is not a one-way communications model. It requires a dialogue, if you will, of explanation reinforced with illustration.
