Constructive choice of the CATV station

Crypton offers a full range of equipment of its own production for building a digital cable TV headend. Crypton adheres to the ideology of building a TV headend station from separate devices built into a standard 19inch rack.

The modular mini station, in which individual modules are inserted into the base unit (chassis), benefits only when very small dimensions are required. In all other cases, separate devices are preferable. Then you are not limited either in the number of pieces of equipment or in the composition, you have more freedom in choosing products from different manufacturers. In case of modification after some time, you will not necessarily have to throw out the old station. Some of the equipment will have the latest technical specifications.

Reception part

In order to meet the needs of all customers, which means to make more money and outperform the competition, a cable network needs a large number of channels. Then subscribers will be able to choose programs to their liking. By the presence of content on satellites, we can talk about the cable operator's software service of at least 100 programs.

Specially for this Crypton has developed and offers eight-input satellite receivers and four-input terrestrial. Satellite receivers have 8 receiving modules, a very high degree of integration and, given the possibility of choosing the desired programs and remultiplexing them into several transport streams, this solution will be optimal for building a Crypton head station.

Only 2 receivers will allow you to inexpensively compose 8 transponders with 128 programs. Try to find a more competitive solution! Consider that many cable networks now have over 500 programs, and imagine what a hardware room would look like with so many receivers!

Modulators

The signals from the receiver (or rather from the multiplexer built into the receiver) are directly fed to the four-channel modulator. Modulators, again in order to save space and cost, are made of 4 pcs. in one body on one platform. Two modulators will give 8 carrier frequencies for those eight transponders received from 2 receivers.

The digital headend is ready! Of 4 units. One receiver-modulator bundle provides four carriers, up to 64 programs. Multiply by the required number of times, you get the desired configuration. Elementary scaling! In order to be convinced of the economic efficiency of such a solution, take a look at the price list. Technical characteristics are maximum possible. If the modulators have an IP interface, then CAS Crypton is already built into them and to organize pay TV you need to buy another CAS server Crypton.
