ANGA Cable 2008 Preview: WISI Communications GmbH & Co. KG (WISI), Hall. 10.2 Stand. E9
WISI focuses on optical systems, network components and intelligent solutions for VoIP, internet and applications like VOD, interactive services and IPTV.
The company also manufacturers satellite set-tops, like the recently launched E 49 model including an HDMI output up-scaling the SD signal to the 720P and 1080i HD ready formats. It will use the ANGA show to launch its first HD satellite receiver.
Wisi is showing new MPEG re-multiplexers in its Streamline and Topline head-ends series. The Compact series will see twin modules added to handle two channels/signals instead of one doubling capacity per rack unit.
WISI STREAMLINE is a modular platform for static transport stream re-multiplexing and the base of developments in the field MPEG Over-IP. The heart of this innovative system is the MPEG re-multiplexer OT XX with an integrated QAM modulator and four CI slots for the support of professional CAMs.
The QAM output module is based on FPGA technology developed by WISI. Around a core processor with a stream switching backplane, up to six front-end modules from various sources like DVB-S, DVB- S2, DVB-T, DVB-C, AV-MPEG2-encoder, ASI, DVB-IP, SDI-DVB2-encoder can be inserted. Up to four CI slots enable the descrambling of the signals that are routed to the re-multiplexer.
Via an ASI-loop, the new content can be scrambled and linked to the output modulator that can be QAM or COFDM. Avoiding external receivers or encoders makes OT 01 a very cost effective, space saving, easy to handle and reliable multiplexer. A new dual DVB simulcrypt scrambler, the OT 32, completes the line-up.
The small brother of the OT XX of the new WISI STREAMLINE series is the dual trans-modulator OV 75M of the Topline Headline family. This module with an integrated re-multiplexer receives two DVB signals and transforms it into one digital QAM channel. OV 75M can also operate as a universal dual trans-modulator producing two independent QAM output signals.
For operators of small and medium-sized cable networks and distribution systems in buildings, the new “all in twin” series of twin modules makes the channel processing even more economical. The new OK 75M module trans-modulates two digital programs from the digital transport stream of a satellite transponder in DVB-S format into two QAM signals for the transmission into cable networks.
The OK 75 M also has a Network Information Table (NIT) that could be easily handled with additional software CS 76. For HDTV, WISI offers the OK 75H twin module.
The OK 89 can receive and process two FTA terrestrial digital TV signals, converting them to analogue PAL signals.
WISI will also use the cable show to launch new analogue (co-ax) distribution amplifiers and house connection amplifiers, as well as fibre connectors and FTTH modules, including the new Fibre CP 10, a triple play fibre CPE.
