Digital Broadcast High-Definition

TV Decoder with PVR Support

The CX2417x family features an MPEG-2 MP@HL video decoder, 32-bit RISC

The multi-format audio decoder supports MPEG-1, MPEG-2, Dolby

The CX2417x also features an impressive array of I/O features, including

CX2417x

(up to six baseband TS interfaces), fully integrated serial and parallel advanced

Conexant’s portfolio includes a comprehensive suite of semiconductor solutions

for broadband communications and the digital home. Conexant’s CX2417x

High-Definition TV (HDTV) decoder features all the major elements required

to implement the core system and decoder electronics of a high-performance

personal video recorder (PVR)-enabled HDTV STB deployed in digital satellite,

cable, or terrestrial TV networks.

CPU, high-definition and standard definition video/graphics display controllers.

MPEG-4 AAC, and aacPlus

PVR functionality is supported by three dual-stream transport processors

technology attachment (ATA) interfaces for hard disk drive (HDD) connectivity,

and 3DES/AES ciphering engines for encryption of data to the HDD. This

functionality enables end users to simultaneously watch and record separate

programs, or record a program while watching one previously recorded. NDS

dual USB 2.0 host controller, PCI bus, and HomePlug

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’s

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.
