AiMS presents the services in the correct layout and corresponding resolution on flat screens, PCs, mobile phones, tablets and STBs with the highest possible bandwidth. According to the trend „Any video in any network with any device at any time" the user is able to take the service to any place with his tablet or mobile phone.

WISI's products for digital TV signal processing and transport are a core part of this unique comprehensive solution, consisting of WISI‘s innovative headend systems CHAMELEON and TANGRAM for TV and IPTV as well as analog and digital fiber transmission systems.

CHAMELEON - single hardware multi-purpose headend

The headend system CHAMELEON is very flexible and can be used in linear TV distribution networks or in multi screen 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 DVB modulators for different inputs, transmodulators, IP- and ASI streamer as well as re-multiplexer.

TANGRAM - high density IPTV video processing

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, PAL and FM. WISI‘s product family TANGRAM is a high density platform for cost efficient realization of these edge applications (Edge QAM, Edge Pal and Edge FM). The system 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.

OPTOPUS - optical RF access portfolio

WISI also shows its 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.

The 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.

OPTOPUS also offers the necessary components RF over Glass network, the FTTx technology for cable networks, using established transmission like PAL, DVB and DOCSIS.

... for the convergence of networks

The TV market is rapidly changing. TV consumption is more and more becoming possible everywhere ("TV Everywhere"). The company`s slogan for this new important development in TV technology is: "Any Video from Any Source to Any Device in Any Network". Network operators have to react and turn their networks seamlessly into content delivery networks (CDN). WISI Communications GmbH & Co. KG (WISI) will present at stand B25 in Hall 5 at IBC (September 9. - 13. 2011) in Amsterdam its new HbbTV MultiScreen content management system solution for the convergence of access networks based on open standards.

Open Standard HbbTV
HbbTV allows network operators with an open application interface to present themselves to their customers on all HBBTV enabled consumer devices with their own GUI (Graphical User interface). HbbTV is already being integrated in Flat Screens or is available as plugins for TV browsers. The same principle is being used for PCs. A further important aspect is that the same content can be offered by so called "Apps" on Apple iPad, Android and Windows mobile tablets by using the browsers and video players of these mobile devices.

Central head end
The WISI solution for a Connected TV/IPTV consists of several building blocks such as the central WISI head end and rgb networks system components. This architecture receives, aggregates, re-multiplexes, transcodes, converts, encapsulates and streams TV and audio data, particularly for adaptive streaming via packet networks such as the Internet and mobile networks. SI data for Teletext and EPGs and others are also provided by the head end. A SI-Server is used to filter the metadata from the DVB transport stream and format them so that IP devices can use, distribute and convert them (Teletext, EPG).

AiMS HbbTV Server
The new AiMS platform adds the HbbTV specific extensions being necessary in Connected TV applications. AiMS HbbTV is a stand-alone Content Management Software for IPTV/Connected TV and Multi Screen environments. It communicates with interfaces of different manufacturers with standardized protocols and XML content presentation for applications and client devices. It supports many IPTV and HbbTV Set-Top Boxes and Flat Screens without the need for any proprietary middleware. A maximum number of devices and operational systems as desktop computer platforms (Windows, Apple, Linux) with market relevant software components (Mozilla, FireFox, VLC Player, Internet Explorer, Windows Media Player, Windows Media Center, Windows Jabber Clients with video, Opera) can be used. AiMS can be installed on industry standard operating systems and standard server hardware. AiMS uses MySQL as default database. Also other databases like e.g. MSSQL, Oracle, PostGresQL can be used. AiMS can be distributed across several servers in a network with conventional methods. They can be addressed appropriately with load-sharing methods. AiMS is a carrier grade Content Management System (> 1 Mio Subs). Two further software components are available. AiMS OTT allows the operator to expand its activities to the internet (over-the-top), for example WEB-TV. AiMS mobile combines HbbTV with Multi Screen and supports Downloadable Apps, runs over-the-top and with secure user authentication. Authentication defines from which AiMS site the data are distributed. All data are provided by the server in XML. The App pulls the channel list (XML) from the server and the channel list contains the URL for the streams with different resolutions supplied by the transcoder, format converter and adaptive streamer.

Next steps
WISI, IPNetCom and rgb networks work on the integration of various VoD, time-shift TV (Catch Up TV) and OTT applications being launched shortly on this platform.
