WISI launches new headend systems

German technology company WISI has introduced two new headend systems, Chameleon and Tangram.

Chameleon will is designed to accommodate the transition to digital and from HFC to IP distribution. Modules can operate as receiver-decoder-analogue-modulator and be programmed to add IP streaming modules that can operate as Edge QAM or Edge PAL as well as IP gateways for DVB-S/S2/T/C signals to feed a backbone and at the same time produce four QAM or two COFDM outputs for the local network. Additional modules being linked via IP interfaces increase the processing capacity of the system, according to WISI.

Tangram includes DVB-IP gateway and Edge products (Edge-QAM, Edge-PAL and Edge-FM) and is designed for acquisition/ aggregation as well as modulator functions to receive, aggregate, transport (via IP) and re-modulate broadcast TV into HFC- and Fttx Fibre Overlay networks. Tangram supports various encoding standards (MPEG2, MPEG4 received from satellite and terrestrial sources) as well as high density re-multiplexing. According to WISI, the system is suitable for IPTV contribution and end-to-end IPTV-based video for residential customers in IP-only networks including xPON, P2P, xDSL and DOCSIS-based IPTV in HFC networks.

Both products will be on display on WISI’s stand at the forthcoming IBC trade show.
