The Definition of Headend System
Headend System is a facility that receives TV signals from satellites. And converts these signals and distributes them to homes and cable networks. It receives and re-modulates the incoming frequency by amplifying them and sends these to the main distribution center to transmit them to the network system.
It is the process of making the video and audio signal compatible with the analog signal to the analog input of our televisions at 47-862 Mhz. Headend Systems are ideal for multi-apartment buildings, hotels, hospitals, prisons, and places like these. Headend system is classified into two types: double-sideband and single-sideband. The main difference between a double sideband and a single sideband is that while the double sideband is left with gaps between the channels, there is no gap between the bands in the single sideband.
Digital Headend Systems
The Digital Headend System is an outstanding technological innovation with many benefits such as high channel capacity, superior image sound quality, and EPG. The system structure has the quality of transmitting many Radio broadcasts from a carrier channel to 8 SD or 4 HD TVs without compromising image/sound quality.
Three advantages of digital TV distribution technology are access over the internet, channel arrangement, and technical support.Digital Headend Systems also offers a large amount of space savings compared to old-style headend technologies in terms of space requirement.
The advantages of the Digital Headend System are as follows:
- High Channel Capacity
- Full HD Quality TV Broadcast High Definition
- Transfer of information containing EPG (Electronic Program Guide) broadcast content information
- Ability to sort TV Channels from the LCN Center
- System control with remote management

Analog Headend Systems
Analog Headend Systems are broadcasting systems that all old and new televisions can access from all points without tools such as additional device converters, where all mass TV access is applied. Because of the structure of this system, only one TV broadcast can broadcast from a PAL carrier channel, and its capacity is limited to 50.60ads and, high-resolution broadcast transmission is not possible with Analog technology.
It is also possible to watch HD (High definition) broadcasts that you cannot watch with classical Headend systems (PAL broadcast system-Analog).
The Features of Compact Headend
- Integrated remote monitoring in the base unit
- Modules for each reception mode
- Low operating costs
- High channel count per basic unit
- Easy handling via USB and web interface
The Features of Satellite TV Demodulators
- Professional solution for central distribution of digital satellite broadcasts
- 4 Channel DVB-S2 HDTV MPEG-2/4 H.264-A / V Demodulator 19 'standard
- The possibility of selecting the Receiver with the IR Select button on the front panel and setting it with a remote control
- LNB voltage can be provided through the 1st and 4th module by demodulators
- Software update with RS-232 interconnection
- 4 Channel DVB-S2 HDTV MPEG-2/4 H.264-A / V Demodulator
The Features of Single Sideband TV Modulators
- As the carrier is not transmitted, this enables a 50% reduction in transmitter power level for the same level of the information-carrying signal.
- As only one sideband is transmitted, there is a further reduction in transmitter power.
- As only one sideband is transmitted, the receiver bandwidth can reduce by half.
- It increases the signal rate by 3 dB so, the narrower bandwidth used will allow less noise and interference.
The Features of Double Sideband TV Modulators
- The output level of all channels can reduce down to -10dB with the menu settings.
- Output frequency setting can be changed as a group by double sideband TV modulators.
- Test Signal giving for each channel.
- Produced with HALF AGILE Technology.
- The desired channel can be closed from the menu.
- Low insertion loss in RF Out (by Input Loop): -1dB
- Seamless performance with fan cooling in hot climate zones.
The Features of Common Antenna Distribution Plants
- Common Antenna Distribution Plant
- 2 Channel Modulator
- Multiband Amplifier 35dB
- 1 RF output
