A method and apparatus are claimed that separate network-dependent from network-independent functions in set-top boxes (STBs), including digital consumer appliances and PCs. A receiver subsystem integrates network-dependent tuner, digital demodulation, Forward Error Correction (FEC), descrambling/decryption, and conditional access functions into a very small format (e.g., any of the PCMCIA Type I, II, or III form-factor). This combination of functions comprises a Digital Interface Conditional Access Module (DICAM). The DICAM interfaces with a Set-Top Universal Box (STUB) that includes network-independent functions. The STUB functionality may also be integrated with a consumer electronics (CE) appliance such as a TV, PC, DVD player, etc. The DICAM may also include an interface for "Smartcards" that implement any of the many different varieties of CA functions currently found around the world.

[ What is claimed is:] [1.] An electronic broadband network communication system comprising:(a) a separate, connectable network-dependent digital interface conditional access module (DICAM) configured to receive an RF audiovisual signal, and generate therefrom an error-corrected digital signal in a transport stream, the DICAM including a stub;(b) a separate network-independent common module configured to be coupled to an electronically communicate with the DICAM, for receiving the transport stream and generating at least a video output signal therefrom, the common module including a socket coupled to the common module, wherein the stub is configured to be connected to the socket so as to allow the DICAM to electronically communicate with the common module.
