Solutions for the merging of TV and broadband Internet - Extension of future-proof headend systems

WISI Communications GmbH & Co. KG (WISI) presents numerous innovations for the build-up and extension of future proof TV headends and next generation networks at IBC (September 7 – September 11) in Amsterdam in hall 5 at stand B25. Highlights are the two extended next generation headend systems Tangram and Chameleon and the Multi Screen Content Management System „AiMS“. WISI also has expanded the product portfolio of its optical access platform Optopus and of its compact headend system OH.


With the ongoing digitalization of the networks more and more video signals are transported via IP. For feeding these IP encapsulated video signals into the analog access networks like RF Overlay or HFC, they need to be converted in QAM, COFDM, PAL and FM. WISI‘s product family Tangram is a high density platform for cost efficient realization of these edge applications (Edge QAM, Edge-COFDM, Edge Pal and Edge FM). The system has been extended by a new encoder module. Tangram offers all required features to be used in professional networks like redundant power supplies, 1+1 and n+1 redundancy, SNMP management, replacement of modules and fans in operation and many more.


The headend system CHAMELEON is very flexible and can be used in linear TV distribution networks or in multiscreen applications. Utilizing a single hardware all Chameleon modules are configured and programmed by software only. This concept reduces the total cost of ownership of the network headend. Among others available software modules for Chameleon are all DVB tuners, DVB and analogue modulators for different outputs, transmodulators, descrambling, MPEG-4 Decoder, IP- and ASI streamer as well as re-multiplexer. This huge variety of functions in one hardware makes the product unique.

Multi Screen Content Management System “AiMS”

The TV market is rapidly changing due to the continuing merge of broadband and broadcast, thus offering the possibilities of interactivity and personalized content. For network operators who would like to keep their ability to compete in this dynamic media environment it is a must to provide video content and multimedia services from any source to any network to any device. Together with the technology partner IP.Netcom WISI will show its comprehensive Multi Screen Content Management Solution AiMS as the ideal response for this challenge. AiMS presents the services in the correct layout and corresponding resolution on flat screens, PCs, smartphones, tablets and STBs with the highest possible bandwidth. According to the trend „Any video from any source to any device in any network” the user is able to take the service to any place with his tablet or smartphone.


WISI also shows its extended optical access platform Optopus. This modular system is highly flexible, has an industry leading density, is very reliable and ideally fits in any optical network such as FTTx networks with RF Overlay or RF over Glass as well as HFC applications. Especially for FTTx networks including RF over Glass applications Optopus offers all necessary components and modules. RF over Glass by using all established transmission formats like PAL, DVB and DOCSIS is the ideal FTTx technology for cable network operators.

In addition WISI offers in its Optopus platform diverse products that allow an optimal cluster splitting. Novelties of the Optopus platform are a cost-efficient O-band transmitter for the separation of networks up to 20km and a high performance DWDM transmitter for broadcast/narrowcast architectures. WISI’s RF Overlay solution based on the OPTOPUS portfolio consists of a comprehensive family of optical 1550nm transmitters and amplifiers. These in particular meet the necessary requirements of blast and split architectures used in Point-to-Point or PON networks.

Headend System OH

WISI has expanded its successful compact headend system OH by the new Twin A/V Encoder OH66. The modular and flexible expandable system offers powerful technology at compact dimensions. The basic unit OH 50 offers slots for up to 14 modules. This allows optimal channel processing of up to 14 analogue TV channels respectively 28 digital transponder streams. WISI offers a broad portfolio of DVB modules, Twin DVB-S/S2 modules and optional accessories, e.g. for the programming and remote monitoring of the system.
