In the future, cards very similar to the broadcast receiver card will probably be built for the cable, digital video disk, Asymmetrical Digital Subscriber Line (ADSL), and Multichannel Multipoint Distributed System (MMDS) environments. Because these network cards will receive broadcast data rather than individually targeted data, and because they have no back-channel requirement, they will require minimal support from a network head end.
