SMALL-FORMAT SUBSYSTEM FOR BROADBAND COMMUNICATION SERVICES

摘要

A kind of method and apparatus, it is desirable that those of individual network correlation is from the set-top box (STBs) of the unrelated function of network, including digital consumer electric appliance and PCs. Receiver subsystem will tuner related with network, digital demodulation, forward error correction (FEC), go scrambling/decryption, condition access function is integrated into very small specification (for example, any PCMCIA types I, II, III close factor). The set of the function includes a digital interface condition access modules (DICAM). DICAM Set-Top, the interface include multiple functions unrelated with network with universal box (STUB). The STUB functions can also be with consumer electronics (CE) equipment, such as TV, PC, DVD player etc.. The DICAM also Ke Yibaokuo & quot; Smartcards" That interface realizes that any many variety classes CA functions are currently found all over the world.
