WISI offers end to end system solutions for cable, IPTV and OTT operators. Our headend systems Tangram and Chameleon offer excellent flexibility and performance for reception, multiplexing, scrambling and transmission to and from any network. The Optopus optical distribution platform offers optical transmitters and receivers for HFC, RFoG and RF overlay.
Inca 4400 high density linear and ABR transcoders and 5420 ABR packager and origin server offers a complete OTT solution with intelligent video monitoring functionality. WISI's range of amplifiers and optical nodes covers requirements for cable TV distribution and broadband deployments using up to Docsis 3.1 in cable networks.
WISI introduces a professional receiver for HLS streams in our broadcast platform Firefly. HLS is used for media file streaming to mobile devices, but using HLS also for linear TV distribution will make each operator platform independent. While deploying new OTT services, each operator can also use HLS as a cost-effective solution to distribute linear TV channels to each sub headend.
Over The Top Headends
Traditional cable operators and broadcasters are challenged by the multitude of OTT services that by definition bypass the operator and create revenues elsewhere. WISI offers solutions for all operators that are cost-effective and tailored to work together with our digital headends. This allows operators to create their own OTT packages, especially live streaming services that let customers view content on any device, through either the cable network or over various broadband connections.
