Interactive television settop terminal architectures

Emerging architectures for Interactive TeleVision (ITV) Settop Terminals (ISTT) are discussed. The differences in the architectures for different delivery mechanisms has impact on cost and complexity of the STTs. The combinations of features required in the STTs and the level of silicon integration sometimes drive the architectures. The state of technology of building blocks required for implementing these STTs and future trends in silicon integration are discussed.
