Background information

Meeting all industry standards for worldwide LCD TV reception, the TV543 supports inputs from analog to digital, SD to HD, broadcast to networked (IPTV, internet, VOD). The first LCD TV solution to feature an integrated MPEG-4/H.264 decoder, it enables the reception and decoding of MPEG-2 and MPEG-4/H.264 SD and HD content.

It is also the first DTV platform to integrate CI+ conditional access, ensuring the best possible protection of content against unauthorized copying. This has the additional benefit for consumers that set-top boxes or PCs are no longer required in the living room.

PNX8543x

The TV543 is based around the Nexperia PNX8543x Home Entertainment Engine which features a MIPS 4KEc and a Trimedia AV DSP, both running at 300 MHz. In addition to the integrated MPEG-2/MPEG-4/H.264 video decoder this IC supports MPEG1, HE-AAC v2 and/or Dolby Digital (Plus) audio decoding. Input is via two integrated HDMI ports. An integrated USB 2.0 host controller is available for media browsing from flash memory or external hard drives. The chips feature integrated dual LVDS outputs and can support 100/120 Hz LCD panels via MCFI.

The reference design also features a choice of ATSC or DVB front-ends based _vh="0">TV543 software

The TV543 comes complete with a set of drivers that offers a low level abstraction of the underlying hardware allowing setmakers to port their own middleware and applications. The drivers allow OEMs to define view modes, picture styles, sound styles, tuning algorithms and more.
