Broadcast and Streaming Media Testing
Launch TVs, set-top boxes and streaming devices that pass certification first time and play every channel, app and stream your viewers expect.
Why broadcast and streaming testing matters
Viewers don’t care whether a programme arrives over the air, through cable or over the internet. They expect it to start quickly, look right and keep playing. Behind that sit dozens of standards, from DVB and ATSC 3.0 to HbbTV, CI Plus, DASH and CTA WAVE, and certification programmes your product must pass before launch.
Resillion helps write those standards and builds the tools used to test them. We test TVs, set-top boxes and streaming devices across the whole delivery chain, so they’re ready for certification and for real viewers.
The aim: TVs and streaming devices that pass certification first time and give viewers a seamless experience on every channel and app.
What we offer
We test across the whole delivery chain. That covers RF and signal testing for over-the-air, cable and hybrid services, and interactive TV app testing for HbbTV and ATSC 3.0, whether apps are broadcast-dependent or broadband-delivered.
We also validate streaming across DASH, HLS and CMAF, and help standards bodies design and run their certification schemes. Our own test tools and suites, plus automation that fits your CI/CD pipeline, mean you can test earlier and more often. With Total Quality guiding delivery, results connect with wider quality and security assurance.

CASE STUDY
Scaling and automation CI+ conformance testing
A global streaming technology platform that powers millions of TVs and devices needed CI+ conformance testing to keep pace with its automation-first engineering. Traditional CI+ testing ran on one device at a time, late in development, so issues surfaced weeks after code was written. Resillion designed a server-based CI+ test harness that runs tests across multiple devices in parallel, and integrated it into the customer’s CI/CD pipelines. Developers can now trigger tests on demand or run them overnight.
The result?
Around 200 CI+ test cases now run automatically, cutting testing from about two weeks of manual effort to under three days. Nightly runs replaced late-stage testing, so developers fix issues sooner and certification carries less risk.

Why TV and device makers choose Resillion
Industry-leading tools
We build and maintain the CI Plus pre-certification tool, Ligada iSuite for HbbTV and Evora iSuite for DVB, so you test with the same tools and suites used across the industry.
Chairs working groups in HbbTV and ATSC
We chair the Improving Interoperability Task Force within HbbTV and the Conformance Implementation Team within ATSC, so we know how requirements are meant to be read.
Broadcast to broadband
From RF and signal testing to interactive apps and streaming playback, one team covers the whole chain your content travels.
Automation and AI-assisted analysis
We build conformance tests into CI/CD and run them overnight. For one streaming platform, that cut CI+ testing from two weeks to under three days.
