HARMONIC INTRODUCES NEW VOD GATEWAY SOLUTION; NEW NARROWCAST SERVICES GATEWAY - NSG - SETS NEW STANDARD IN PERFORMANCE AND EFFICIENCY.Harmonic Inc. (Nasdaq:HLIT) has unveiled its Narrowcast To transmit to selected individuals. Cable TV and satellite radio are examples of narrowcast services because they reach only their subscriber base. Mailing lists are another example. Contrast with broadcast. See multicast. Services Gateway 8100 (NSG NSG Naturschutzgebiet (German: Nature Reserve) NSG Nuclear Suppliers Group NSG National System for Geospatial-Intelligence NSG Naval Security Group NSG National Security Guards (India) ) to facilitate the next generation of Video-on-Demand (VOD See video-on-demand. VoD - video on demand ) services. The NSG is an innovative fully-integrated server gateway that enables MSOs to deliver VOD content economically and manage bandwidth more effectively. The NSG 8100 reduces the cost and complexity of launching and supporting VOD services and enables service providers to develop a viable VOD business model. The smallest VOD gateway available today, the NSG is based on open architecture and interoperates easily with the other essential components of a VOD deployment. Traditionally, VOD headend systems required multiple costly subsystems to deliver appropriate video signal processing See DSP. and management. By combining many of these functions into a single compact platform, Harmonic lowers the cost and complexity of the head-end system and reduces cabling, integration and maintenance expenses. Harmonic's NSG is a critical component of a complete VOD deployment, providing the processing of multiple high capacity server inputs, multiplexing, program filtering and routing, conditional access Conditional Access (acronymized CA) is the protection of content by requiring certain criteria to be met before granting access to this content. The term is commonly used in relation to digital television systems, most notably satellite television. scrambling, and an eight channel QAM (1) (Quality Assessment Measurement) A system used to measure and analyze voice transmission. (2) (Quadrature Amplitude Modulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). modulation and upconversion. The most compact VOD gateway in the industry, NSG is the only solution to support eight QAM channels in a single rack unit (RU). Due to its advanced thermal design, thermal spacing is not required. Since VOD deployments require hundreds of QAM channels in a single cable headend or a hub, the NSG's compact construction reduces both the space and the capital investment needed to launch VOD service. |
