Excellence in analogue headends
The DVX platform is a professional and versatile headend platform for cable TV systems. The platform includes products for content acquisition, signal processing functions and backbone transmission. The modular system provides a future proof migration path to new services and technologies such as Mpeg4 and HDTV. The basic building block of the DVX platform is a 19” wide 6RU high subrack that complies with ETSI telecommunications standards. Together with a power supply and a wideband output module, each subrack can house up to nine signalprocessing units with a cable output.
The DVX platform offers ultimate flexibility for building a cable headend. All functions are performed by individual units that can be added to the system as needed. The units can be organised based on requirements such as logical channel order or func tionality of the units. Builtin features such as power backup and RF com bining make it very easy to deploy the system. The architecture allows an operator to expand the system in phases along with his business requirements, all based upon an open and flexible architecture.
Low Power Consumption
One of the features of the DVX platform is system level powering, which provides remarkable savings in power consumption as a single power supply caters for a number of signal processing units. Low power consumption means additional savings on airconditioning as less heat is dissipated. The third dimension is increased reliability and prolonged lifetime as the units run cooler.
Based on standard interfaces
One of the key features of the DVX solution is its openness. All processing of digital and analogue content is based on existing standards such as MPEG2, DVB and IP. All interfaces in the system are based on industry standards, which makes it very easy to complement the DVX solution with any third party equipment or to scale and interoperate with other industry standard architectures. Implementing standardsbased systems also allows operators to easily interface to other networks to expand their operating area.
The DVX platform is deployed in several locations world wide. It has shown its reliability during system operation in these systems. The versatile backup functionality enhances system reliability both in terms of hardware and services. Savings on power consumption reflect directly on improved temperature behaviour. This means longer component life and thus improved reliability. The DVX platform consists of a full range of analogue functions with user friendly, simple control and management tools. It offers high flexibility for building a cable headend as all functions are performed by individual units that can be added to the system as needed. The units can be organised based on requirements such as logical channel order or functionality of the units.
