Committed to flexible digital TV and PC/TV solutions,
Philips Semiconductors has developed a complete
DTV receiver reference design based on proven ICs from
other reference designs. It is laid out according to Device Bay
physical specifications and allows a DTV transport stream to be
carried over Device Bay or IEEE 1394 connections.

Reference design
Highly integrated DTV front-end, with
IEEE 1394/Device Bay transport stream output
In the fast moving digital broadcast market, where TV and PC
technologies are converging, the high performance IEEE 1394 bus is
now
the
established high-speed, real-time true plug-and-play serial bus
system. As its popularity grows, it is becoming the accepted standard for
connecting a variety of digital consumer electronics equipment to each
other, as well as to multimedia PCs and workstations. Drawing on
Philips Semiconductors鈥?acknowledged expertise in digital TV systems
and IEEE 1394 interface devices, this reference design combines these
technologies in the emerging Device Bay format, creating a simple
high performance DTV receiver for PC and other IEEE 1394-based
applications.
Based around a proven 8-VSB (Vestigial SideBand) demodulator with
on-chip digital tuner AGC control, used in the established 鈥楥oney鈥?/div>
PCI-based ATSC/NTSC PC-TV board, this reference design also
incorporates Philips鈥?advanced IEEE 1394 devices: a high-performance
Link layer controller with isochronous operation and embedded
IEC61883 support; and a three-port Physical layer interface. These
high-speed devices enable the digital TV signal (MPEG2 transport
stream) to be transferred over the IEEE 1394 bus at 200 Mbits/s, output
via either 1394 port or Device Bay connections.

This reference design enables platform providers to concentrate on
developing the user interfaces and applications that will differentiate
them in a market where competition is very fierce. A licence is available,
