Ikusi HTL-TT2 DVB-T Transmodulator Regenerator

Ikusi offers the only tested solution to convert MPEG4 HD format into MPEG2 SD format. The HTL-TT2 module allows using existing legacy SD TV
sets once the new HD DTT arrives.
– Right solution
With Ikusi transcoding solution, you don’t have to change the existing legacy SD TV sets and you can continue watching the
latest content. Ikusi headend gives you the time you need to decide when and how to upgrade your TV devices.
– Experience and reliability
Ikusi is the European leader in hospitality market and more than 3.000 sites have our solution installed, many with more
than 4 years of continuous service. During this time, our solution has faced many signalling changes and has adapted its
configuration to all of them automatically. Our installers can be confident because they don’t need to rely on new and untested
– Evolving solution
We continue developing transcoding solution and adding new features to our headend. All these coming features will be at
your disposal free of charge. For example, DVB-C output has been recently implemented.
To upgrade your headend, you just need to visit our website, download the latest firmware version and install it. 100% free.
The HTL-TT2 module is able to receive services from 2 different input muxes and to combine them into a single DVB-T output.
It can manage both HD and SD services in MPEG4 H.264 or MPEG2. One of the modules in each headend is designated the master module. Having a
single configuration interface simplifies setup and maintenance. The headend is managed as a whole instead of module by module.
