HDR-106
MPEG2/H264 – 4:2:2 – 10 bits – DVB-T2/T Diversity 6 – DVB-S2/S Receiver
MANUAL 7.0
Chapter 1: Introduction
The new HDR-106 receiver performs DVB-T2, DVB-T, DVB-S2 (optional)
and DVB-S (optional) demodulation. The latter enables compatibility with
nearly all types of COFDM transmitters. The former modulation outperforms
DVB-T modulation and offers much higher data rate and therefore, higher
quality signal or much more robust signal than DVB-T, making possible
longer and more difficult links. The DVB-S2 modulation outperforms DVB-S
modulation because the DVB-S2 has four modulation modes available
(QPSK, 8PSK, 16APSK and 32APSK) while the DVB-S only has one
modulation available (QPSK). Besides, DVB-S2 uses LDPC code while DVB-S
employs Viterbi code.
It integrates diversity 6 DVB-T2 and DVB-T demodulation, using spatial
diversity based on MRC (Maximum Ration Combining) technique with the
DVB-T standard and TS switch with the DVB-T2 standard, which reduces the
effects of multipath and fading losses.
An important feature of this receiver in DVB-T2 mode is that it is not
saturated in case of receiving RF signals with a very high signal level.
Another feature is the implementation of the DVB-S2 and DVB-S
demodulation. This device is capable of receiving DVB-S2/S signal with a
baudrate range from 2 to 45 Mbaud/s. This receiver also has an LNB supply
available so as to power up the Low Noise Block.
The down-converters are connected to an independent receiver antenna in
order to provide diversity. This allows the user to install different antennas
in order to take advantage of their combined characteristics, or employ
antennas with similar characteristics oriented in different directions in order
to offer wider coverage. The use of a diversity system makes the link more
robust and offers better performance than a non-diversity system.
This receiver features H.264 and MPEG-2 decoding for high definition (HD)
and standard definition (SD) signals. H.264 compression makes possible HD
signal transmission and reception using 40% lower bit-rate than
conventional MPEG-2 systems. Moreover, it works in 4:2:2 with 10 bits.
MPEG-2 has been included so that the new HDR-106 receiver is backwards
compatible with previous SVP transmitter systems.
Based on the ultimate and most advanced NTT-NEL H.264 compression
technology, the new HDR-106 offers the highest video quality with the
minimum end to end latency available in the market, 33 ms. For added
security, encrypted transmitted signal can be decrypted using BISS or AES
decryption technology.
ASI input and Transport Stream over IP input make possible to use this
receiver as a standalone decoder. Besides, the ASI output and the
Transport Stream over IP output enable the user to handle the receiver as a
demodulator.
