Dual Decode HDTV MPEG-2/H.264/VC-1
Video Decoder
CX2427x
Conexant’s portfolio includes a comprehensive suite of semiconductor
solutions for broadband communications and the digital home.
Conexant’s CX2427x is a highly integrated, triple-display dual decode
MPEG-2/H.264/VC-1, DIRECTV/DVB compliant, back-end decoder IC solution
for high-definition digital TV systems with support for personal video recorder
(PVR) applications, which can be deployed in digital satellite, cable, Telco or
terrestrial TV networks.
The CX2427x family features a flexible, multi-program HDTV multi format video
decoder capable of decoding two HDTV programs simultaneously in any dual
stream combination of MPEG-2, H.264 and VC-1 formats. Three TV outputs
are supported, a primary HDTV display with simultaneous down-converted
SD output, plus an independent down-converted NTSCL/PAL SDTV output.
The dual multi-format audio decoder supports multiple audio format decoding,
including MPEG-1, MPEG-2, Dolby
®
Digital, Dolby Digital+. MPEG-4 aac and
aacPlus™, WMA and WMA Pro. An integrated ARM1176 CPU with 128KByte
L2 cache supplying over 800 Dhrystone 1.2 MIPS at 666MHz, and a high
performance, unified memory, dual 667MHz 32-bit DDR-2 SDRAM memory
controllers give ample processing power for advanced applications and future
expansion capability.
PVR functionality is supported by two multi-stream transport processors,
each of which is based on a dedicated RISC engine, with each supporting six
simultaneous transport streams (3 from baseband inputs and 3 from DMA
interfaces). Each transport processor unit also supports DVB, DES, AES or
Multi-II descrambling and contains hardware support for the NDS conditional
access system. The CX2427x integrates dual serial ATA2 controllers with
Conexant Product Portfolio
The company’s broad portfolio of semiconductor products also includes client-side DSL and cable modem solutions, home network processors,
