The B-NOVA chassis B-NOVA architecture
The B-NOVA chassis has 6 module slots for interface and
processing modules. The B-NOVA architecture is future
proof to support new module development later on by ha-
ving all stream processing features in sub modules. The-
refore, new functionality can be introduced later into the
platform without touching the chassis.
The BLANKOM Digital B-NOVA Chassis is a base for an IPTV
modular platform and cable TV headends. B-NOVA enables
the operator to setup a very compact headend configuration
using various processing and interfacing modules. B-NOVA
scales from one chassis ”headend in a box” to a multiple
chassis system for bigger headend system. Designed for
very high performance, high density and very low power
consumption.
B-NOVA business benefits:
Fully modular platform that grows with your business, Energy efficiency also reduces site cooling requirements
from a compact 1 RU ”headend in a box” to a multisite,
distributed headend solution Internal switch for cable free interconnections and
simplified maintenance
Platform’s small footprint enables efficient space usage
Advanced DVB stream processing offers flexibility for
Low power consumption enables longer module lifetime channel creation and simplicity in multi-vendor
and lower energy costs. environments
