STB background

Set-Top Box (STB)

Set-Top Box Software & Hardware Design

The Promwad Electronics Design House develops set-top boxes for hybrid, cable, terrestrial and satellite digital broadcasting. We help our customers to create new products for their business: Set-top box or STB devices and software for DVB, OTT and IPTV solutions.

We take responsibility for all the engineering issues of STB development including industrial and electronics design, middleware and special apps. The result of our work is a ready-made device or application for the world or local market that can be used by millions of people.

Robust development process in Video Delivery & DTV projects


The digital TV area is one of the most dynamic: competencies are getting outdated, technologies are developing quickly. That is why the industry seeks narrow expertise and  developers with versatile qualifications.


We form and dedicate our expert teams to targeted tasks as soon as the clients need that. That measure saves 30-50% of the costs. The average volume of these activities can result in 2000-3000 hours. Clients save around $20 000-30 000 on average.

Our solution


At least 15% of the working time all our developers spend on training and professional growth without exception.


Due to our business model's specific nature, we continuously face tasks and challenges from different technological areas. That has allowed us to accumulate in-depth experience, which we are always ready to share with our clients and partners.


Working with us, clients get access not only to the core team but also to the knowledge base accumulated by Promwad over the years.

Why should you trust us?

Promwad STB development

Satisfied customers

Our first project was finished more than ten years ago, in 2008. We have helped a number of major European companies to transition their viewers from analogue to digital broadcasting. Since then, we have successfully created dozens of new devices and applications and become the leaders in STB development. So, the first reason to trust us is our experience and good references.

Close partnership with vendors

The second reason is our partners. To become the first, you need to work with the best! And we’ve done it partnering with top chip vendors, so that’s how we get the optimal electronic components for your set-top boxes and receive priority tech support.

We build effective relations with technological vendors


Vendors seek support and engineers on the local market. Besides, they struggle while promoting their products and accepting adequate feedback; hence, it is challenging to eliminate bugs and deliver high-quality SDKs.


Through a comprehensive approach and a well-established development & management process, we can reduce time and labor costs on projects that require vendors' solutions integration by 7-12% of the market average. With an average volume of $500 000-700 000, this 7% can save customers $50 000 and more.

Our solution


We integrate various vendors' solutions into our customers' products, so we often see bottlenecks or undetected benefits that add value to our interaction with vendors.


Not being a manufacturer, but rather a user or even a consumer, we can form real and honest feedback on performance, usability, and quality of this or that solution.

"In just 4 months after the start of development, a working prototype was ready, and after 10 months we reached production volumes of tens of thousands of products. Today, our IPTV set-top box is available for sale and competes on an equal footing with Aminet and Motorola."
