13.12.1. General description
The STV0700 controller contributes to offer an optimized, homogeneous and complete solution for
digital TV receiver and Set Top Box manufacturers that want to quickly implement the Common
Interface. The STV0700 includes the necessary I/Os to interface to the MPEG Transport stream
generated by the receiver demodulator and daisy chain it through two independent Common Interface
modules and back to the demultiplexer. The STV0700 interfaces with major digital TV receiver
microprocessors. An I
Signal Generator (UCSG) maps CPU control bus into Command Interface control signals. To minimize
pin count, host address and data buses transit through external buffers that are driven by the STV0700.
The STV0700 includes a memory mode that allows the use any of the Common Interface slots to read
and write an 8-bit PC Card Memory card. This feature gives the receiver memory extension capability
for software upgrade or better performance.
