NXP PCI Express hybrid (DVB-T/analog) PC TV Mini card reference design PCV540

The highly integrated PCV540 reference design brings hybrid TV reception and DVR features to power-conscious notebook PCs and specialty form factors such as compact ‘all-in-one’ PCs. On a small PCIe Mini card, the PCV540 handles complete TV functionality including worldwide analog TV tuning, DVB-T digital TV tuning and demodulation, analog TV video/stereo decoding, and multi-format digital A/V encoding — making it an ideal choice for products in Europe and other DVB-T markets.

A complete, low-BOM reference design, the PCV540 processes hybrid TV streams
using only a few key components: a lownoise multi-standard tuner, a low-power DVB-T channel decoder, and the highly integrated SAA7163FE PC TV IC. In addition to decoding broadcast TV video and stereo, the SAA7163FE encodes analog A/V for recording features in hardware. By offloading the host CPU of this cycle-consuming
task, it enables PC manufacturers to utilize lower-cost CPUs without compromising
performance or picture quality.

The SAA7163FE ensures high-quality reception under the most demanding conditions through advanced 3D comb filtering, 3D noise reduction and dynamic echo cancellation. It also handles highquality scaling, vertical blanking interval extraction, remote control support for TV and recording, multi-layer content protection (Macrovision detection), and CGMS-A extraction.

PCV540 is supported on popular Windows operating systems and third-party TV/DVR
applications. Board setup and control is handled through the Windows WDM driver
AVStream Class with BDA Extensions. The reference design includes a PCIe Mini
card, all necessary drivers, a user manual, schematics, a BOM, Gerber files, and
documentation.

微型卡PCV540的主要指标：



The PCI Express single-channel PC TV capture/encode IC, SAA7163E is a highly integrated solution for bringing popular hybrid TV reception and popular recording features to PCs.

The SAA7163E demodulates and decodes analog TV (video and stereo audio) from
innovative silicon tuners, high-performance can tuners and a variety of channel
decoders. It captures worldwide digital TV broadcast standards enabling support for
a variety of hybrid (analog/digital) receiver designs. A state-of-the-art video compression
engine encodes the AV stream for features such as PVR, time shifting, and streaming media content to the PC or portable devices. Video and audio can also be captured from devices such as cameras, camcorders, and VCRs and recorded to HDDs, CDs, and DVDs.

The SAA7163 achieves exceptional picture quality through advanced features such
as low-noise, high-quality ADCs, subpixelaccurate scaling, adaptive 3D comb filters
and 3D noise reduction. Certified three level Macrovision® detection circuitry ensures the video’s original analog copy protection remains intact. Premium TV content is protected through 128-bit AES and (T)DES encryption. Vertical blanking interval (VBI) data slicing is supported for most worldwide standards. A PCI Express (PCIe) 1.1-compliant architecture ensures ample bandwidth for streaming features.
Software and reference designs

The SAA7163E has a high-level command and response interface (CRI). Broadcast
driver achitecture (BDA) drivers and protected BDA (PBDA) drivers (included) use the CRI for plug-and-play applications.
Reference designs are available for various combinations of analog and digital TV
signal sources.

SAA7163主要特性：

Single-channel design enables efficient watch and record in different formats, rates or resolutions
Worldwide TV video/audio decoder supports current and legacy standards
Supports a wide range of channel decoders: ATSC, DVB, ISDB and more
Multi-standard digital video/audio encoder supports PVR, time-shift, and other recording features (with PC host)
Multi-standard low-IF demodulation supports NXP silicon tuners
Captures a transport stream (serial or parallel) from a digital TV demodulator
Integrated RC receiver/transmitter
Exceptional video quality achieved by adaptive 3D comb filter, 3D noise reduction, andsubpixel-accurate scaling
PCI Express X1 interface
