PNX8550 Nexperia Home Entertainment Engine For Mid- To High-end Analog/digital TVs

The Philips NexperiaTM PNX8550 is a highly integrated media processor for building mid- to high-end Analog/Digital and digital TV receivers with advanced TV and connectivity features. On a single chip, PNX8550 integrates conditional access, MPEG-2 transport stream demux, Video decoding, high-quality Video enhancement, Audio decode and mixing, graphics generation, image composition, and Display It supports simultaneous input and processing of two SD or one HD MPEG streams and two independent outputs for a primary TV screen and a secondary Analog device such as VCR. Dual-stream processing also enables support for double window applications such as picture-in- picture and side-by-side pictures. In basic or advanced configurations, PNX8550 offers extensive Video quality enhancement of Analog or digital sources including industry standards such as Digital Natural MotionTM or proprietary algorithms. It supports a wide variety of Display types, sizes, and aspect ratios, including HD progressive output for driving wide-XGA class plasma or LCD Displays The PNX8550 's highly integrated Nexperia Home architecture enables support for basic and advanced TV applications and product configurations. Powerful MIPS32 and TriMedia processor cores work together with on-chip units to efficiently handle media processing functions in hardware and software. The MIPS32 PR4450 core controls and balances all on-chip functions; two TriMedia TM3260 cores handle real-time media tasks, many advanced Video enhancements, and all Audio operations. On-chip I/O and coprocessing units perform or assist in core Video functions such as media I/O, Video decoding, scaling, Video quality enhancements, Display composition, and preparing media streams for Display High-speed data and control buses connect CPUs and on-chip units with each other and with main memory. Support for PCI XIO, USB and 1394 connectivity standards make a wide variety of connectivity features possible. A variety of PNX8550 configurations support many advanced TV features and services: Add an optical or hard-disk drive to enable personal Video recording or time shift record/playback. Configure a portable Flash reader to support MemoryStickTM and similar formats. Add a return channel and software for interactive TV features like web browsing, shopping, e-mail, chat rooms, and MHP/OCAP applications. Add an H.32x codec for videoconferencing For PNX8550 application development, the NH-8550 SDK includes reference hardware, a programmable remote control, Audio Video streaming software, operating systems, sample and demo applications, and documentation. It is available to Partners through the Nexperia Home Partner Program.
