MODULAR SET TOP BOX ASSEMBLY

摘要

A digital data transceiver is provided, such as a set top box, having a central processor (201) and at least one module (206) which may be removably connected to the processor (201). A plurality of modules (205, 206, 207, 208, 209, 210, 211, 212) may be connected to each other and still communicate with the central processor (201). This allows a consumer to purchase a set top box having minimal functionality required to meet the user's basic requirements. Additional modules can be added to the basic box (301, 302 and 303) to provide further functionality as a user requires. A system of authenticating modules is also provided for configuring modules or updating modules software required.
