connectivity via a
high-speed UART.
For a complete HDTV hardware design, the only additional components
required are a tuner, demodulator, modem codec, audio DACs, double data
rate (DDR)-synchronous dynamic random access memory (SDRAM), and
flash memory ICs. This high level of integration enables a low-cost system
bill of materials and allows the flexibility of supporting different modulation
and compression technologies with a low cost, highly featured MPEG
solution. The CX2417x decoders can be used in conjunction with Conexant鈥檚
CX24118 satellite tuner and advanced modulation demodulators such as the
CX24116 DVB-S2 demodulator or the CX24114 8PSK demodulator, providing
a cost-effective STB semiconductor system solution for MPEG-2 and MPEG-4
advanced video coding (AVC/H.264) HDTV broadcast receivers.
