Set-top Box Solutions Satellite Digital Broadcast High-Definition TV Decoder with PVR Support CX2417x 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. ™ ™ Distinguishing Features • DVB/DIRECTV® compliant back-end HDTV decoder for worldwide markets • XTV PVR with serial ATA interface • Primary HDTV display with simultaneous down-converted NTSC/PAL SDTV output • High-performance 32-bit 250 MIPS ARM920 CPU with Linux and Windows® CE-compatible MMU • Glueless interface to MPEG-4 (AVC/H.264) co-processor • Multi-format audio decoder supports MPEG-2, Dolby Digital Plus, MPEG-4 AAC, and aacPlus • Advanced security features including secure boot software authentication, IC personalization via OTP memory, and 3DES/AES ciphering engines • HDMI transmitter with high-bandwidth digital content protection (HDCP) support • High performance de-interlacer with 480i or 1080i to 480p/720p conversion 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. Part Number CX2417x Description Digital Broadcast High Definition TV Decoder with PVR Support Set-top Box Solutions Satellite The ARM926 CPU in the CX2417x provides up to 250 Dhrystone 2.1 MIPS and enables complex, feature-rich middleware platforms, such as OpenTV® and MediaHighway™ to be adopted by broadcasters. The advanced CPU platform delivers performance that can be deployed by STB manufacturers in a variety of ways, including improved interactive application loading and EPG scrolling performance, hardware feature differentiation via multimedia host signal processing and scalability to Linux®based software platforms via memory management unit (MMU) hardware support. A telco return channel can be supported via a direct access arrangement (DAA) interface to a V.22-V.92 hardware or software modem, or via PCI interface to a DSL, Ethernet or wireless broadband modem. advanced Security features The CX2417x incorporates an advanced security technologies that greatly enhances the ability of broadcasters to protect their service against piracy. Using an advanced on-chip onetime-programmable (OTP) memory technology, Conexant offers broadcasters the ability to personalize individual STBs via the system IC with unique serial numbers and encryption keys. This allows the broadcaster to secure transactions between the STB Smart Card and the System IC. The CX2417x also includes embedded cryptographic technology to allow secure authentication of the STB system software that is loaded into the flash memory.
