HDT-70_H.264
High Definition Camera Transmitter
MANUAL V9.0
Features
Input video signals, composite video, 3G –SDI, HD-SDI, SD-SDI or HDMI
are MPEG-4 encoded, together with 4 analogue audios, 2 stereo AES/EBU
channels or 4 digital audios embedded on the SDI signal. The video
formats can be 1080p (only in Standard Delay mode), 1080i, 720p, 576i or
480i. This transmitter also has a test pattern and test tone generator
available.
This device has a data channel available that allows transmitting user data
or GPS data as well as a Transport Stream ASI input so it can be used as a
repeater.
The encoder uses a H.264/MPEG-4 Part 10 video compression that provides
output bitrates from 1 Mbps to 216 Mbps and a MPEG-1 Layer II audio
compression which supplies different audio bit rates (128, 192, 256 or 384
Kbps).
Encoded signals can be encrypted using BISS-1 or BISS-E scrambling
system. Encrypted signal will only be received by the receivers that have a
valid descrambling key.
Transmitter system operation is very easy. It has a display and a keyboard
which make possible the configuration and monitorization of every
parameter of the equipment.
The equipment is fed with AC power supply from 90 to 240 V.
Its excellent design, mechanical and electronic assembly make the HDT-70
a robust and reliable solution.
DVB-T2 features
Its maximum output power is 3 Watt. High quality components have been
used to achieve the best output signal quality.
The HDT-70 digital camera transmitter uses COFDM (Coded Orthogonal
Frequency Division Multiplexing) modulation system (1K, 2K, 4K, 8K and
8K.ext) which provides superior signal robustness and a higher link
performance. This technology provides operators with efficient means to
overcome the challenges of NLOS propagation and mobile channels
propagation.
OFDM spread spectrum modulation system distributes the data over a large
number of closely-spaced carriers, for example, 1.705 carriers in 2K mode.
The data are divided into several parallel data streams, one for each carrier,
so, each carrier transports a lower data rate and the symbol duration is
longer. Each carrier is then modulated with a QPSK, 16QAM, 64QAM or
256QAM scheme with a constellation rotation.
