Description of the Wisi Chameleon HeadEnd Station

The Chameleon Universal Modular Home Station is designed by the German company WISI to effectively address a wide range of tasks at the HeadEnd Stations, both low-budget providers and global operators of large networks. The unmatched flexibility of the Chameleon HS is provided by the hardware structure of the base module with universal receiving tuners and a processor on programmable logic matrices of FPGA with a wide range of programmatic functional components. The chosen concept allows you to programmatically change settings or upgrade HeadEnd Station modules at any time by installing functional options.

A set of software options is virtually unlimited, after their installation on the modules activate the necessary functions to solve the tasks or input /output ports. Flexible software provides a number of convenient features:

• The HeadEnd Station receives the required set of functions
• Extend the capabilities of existing modules when needed
• Remote activation of modules without the need to replace “iron”
• Easy management of the HeadEnd Station via the Internet using the WEB interface
• Attracting technical support from the manufacturer in case of difficulties when setting up, activating new features, or upgrading software

The concept of the HeadEnd Station allows the operator to buy the required number of modules, and to change the format of the broadcast and the expansion of functions, it is enough to install the necessary software options.

The developed solution saves money considerably and accelerates modernization processes. The base of the station is a universal dual channel programmable GNHWUW2 module in the 3U construct with a set of input /output ports 3xF, 2xBNC, 2xCI, 2xRJ45. To install the modules, four types of chassis GN 01, GN 20 (for small projects) and GN 40, GN 50 (for large-scale projects) have been developed.

To install the modules, four types of chassis GN 01, GN 20 (for small projects) and GN 40, GN 50 (for large-scale projects) have been developed. Interaction between modules occurs with the built-in chassis of the IP-switch, and in the module receiving and transmitting IPports. With the increase in the number of modules proportionally increases the processing capabilities of the HeadEnd Station with stable performance. Module functions provide reception of DVB-S /S2 /C /T /T2, IP, ASI, descrambling, (re) multiplexing, scrambling, MPEG-2/4 decoding, HD-SD Downselling, PSI /SI editing, etc. .

To turn on video signals into the digital HS, WISI has developed a 4-channel GNHWENC2H 4-channel encoder with four HDMI inputs in the HeadEnd Station Chameleon, which allows for encoding of four SD /HD TV signals in the MPEG2 or MPEG4 standard and, thanks to the built-in multiplexer, combine them into an independent multiplex, or add to the existing multiplex. A wide range of programmable features, flexible configuration, versatility of the module, compact design, remote control with the WEB interface, technical support from the manufacturer – all this in a complex ensures the stable operation of the HeadEnd Station Chameleon, its rapid upgrade, meets the stringent requirements of digital broadcasting and completely satisfies the needs of the operator, even in a limited budget.
