 Addressable
Cable System – The network operator
installs an addressable
set-top box (STB) or equivalent device that connects to the
subscriber's display device, such as a television. The network operator
can then switch on and
off
channels and other services that this subscriber is willing or
unwilling to pay for. For
the system to work, the network operator has to install an encrypting
system at the headend
and/or in the equipment on the customer premises. Pay channels (and
that can include video
on demand) and other services are delivered to the customer in
an encrypted mode
which
will then be decrypted (descrambled,
decoded) by the consumer's set-top box
(or equivalent device) so it can be displayed
on
his TV or other display device.
As each customer' computerized system has a unique identification, perhaps in the form of an IP address, that customer's interests can be noted and advertising and other services oriented toward that customer's specific interests might be sent to that customer. Addressable Converter
