Direct Broadcast Satellite (DBS) has been one of the most successful new product
introductions in the history of consumer electronics. This product represents the first
application of digital video compression for broadcast television. Originally intended to
provide cable quality television services to remote areas, this product is now offering a
competitive replacement to cable services in many urban areas.
The first operational systems employ closed proprietary signaling structures. The
European Broadcasting Union (EBU) has developed the first open standard (DVB-S) for
DBS services. The broadcasting community has embraced this standard which is now
being adopted for new systems throughout the world. This widely accepted open
standard is essential for DBS to achieve full market potential.
The HDM8515
TM
is a fully DVB-S&DSS compliant ADC/QPSK demodulator/FEC device
which provides an MPEG-2 stream to be processed by the conditional access and video
decompression circuits. The demodulator clocked with a fixed frequency is true variable
rate over the range of 1 to 55M symbols-per-second. This product achieves the highest
performance and flexibility. It minimizes the cost of external circuits, thus reducing
overall system cost.
