Abstract
An architecture (200) for distributing digital information to subscriber units (202) wherein selection from among multiple digital services is accomplished by transmitting a tuning command from a subscriber unit to an intermediate interface (206). The intermediate interface (206) selects the desired service from a broadband network and transmits it to the subscriber unit (202) over a bandwidth-constrained access line. The bandwidth-constrained access line may be implemented with existing infrastructure, yet the subscriber unit (202) may access a wide variety of digital information available on the broadband network. Universal broadband access is thus provided at low cost.
Output bandwidth of broadcast equipment may also be optimized.
Output bandwidth of broadcast equipment may also be optimized.
