Description

BNC Interface Digital TV Modulator Support SISO MISO Constant Temperature Crystal Oscillator?
?
Overview
?
? HDQ-5041 DVB-T2 modulator is our new product developed complying with the DVB-T2 standard. With its advanced modulating technology, this modulator can effectively make use of the ground spectrum resources and make it possible to provide reliable signals for fixed, mobile and portable devices. Compared with DVB-T, the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold
? Moreover, this device can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T2 STBs
?
Main features

Introduction
?

This proposal describes Hooray Vision’s offer for maintenance and support of the proposed system’s infrastructure. The services covered within this document are structured in a modular format to allow you to understand and choose the respective service content according to your own internal and external requirements and organization.
?
What are the benefits of this service offer?
?

Hooray Visionhas over recent years, invested heavily in specialist support services for the Broadcast, Network and Film industry.

Hooray Visionrecognize the importance of investment in high quality customer services. Over recent years the industry is looking more toward outsourced service support. Cost effective maintenance programs and annual fixed cost support contracts take away the uncertainty of unbudgeted costs.
?
A common Industry objective: Reduce costs of downtime
?

This model is well established within many high tech industries including defense, telecommunications and information technology. Professional Television Broadcast or Network industry is no different. This industry requires more certainty in costs and overheads. With high value equipment running during many years, ever increased value applications, the business of television cannot afford to have delays in broadcasting and downtime in play out/live applications.

?

More and more companies are now striving to reduce costs, remain within fixed budgets yet still have a continuous level of service. As with many other technical industries, having an over staffed internal technical infrastructure, with major spares holding and inventory management is no longer an efficient method of supporting these high value applications. Streamlining service and outsourcing specialist support to dedicated and highly trained experts is a far more cost effective solution.

?

Technology has also advanced at a high pace. With this advance, come both benefits and issues. More complex software applications and feature rich hardware solutions have created a need for highly trained maintenance staff to monitor and maintain such systems. Ensuring applications are running efficiently and effectively mean you get the most out of your investment. Hooray Visionhas developed a range of specialist services, which address this area.
?
What kinds of service?
?

Hooray Visionhas developed a range of services, which meet the aspirations of today’s Broadcast and Network industry. Hooray Visionhas adopted a consultative approach to service.

Working in partnership with its Clients, Hooray Visionservice is providing a best-cost professional service offering, tailored to be flexible enough to meet the rigorous demands of this fast paced sector.
