1 / 4 page Set-top Box Solutions Satellite Distinguishing Features 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. The CX2417x family features an MPEG-2 MP@HL video decoder, 32-bit RISC CPU, high-definition and standard definition video/graphics display controllers. The multi-format audio decoder supports MPEG-1, MPEG-2, Dolby® Digital, MPEG-4 AAC, and aacPlus™. PVR functionality is supported by three dual-stream transport processors (up to six baseband TS interfaces), fully integrated serial and parallel advanced 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 XTV™/RASP™ technology is also supported in the hardware. The CX2417x also features an impressive array of I/O features, including dual USB 2.0 host controller, PCI bus, and HomePlug® 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’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.
