Key Terms

cloud-native, transcoding, hbbtv, descriptive audio

4 terms

cloud-native technical

"leverages a cloud-native foundation, AI-powered EyeQ™ encoding technology"

Cloud-native describes a way of creating and running applications that are designed specifically to operate smoothly on cloud computing platforms. Think of it as building a house with flexible, lightweight materials that can be easily moved, scaled, or adjusted as needed, rather than using rigid, traditional construction. For investors, it signifies technology that is more adaptable, efficient, and capable of quickly responding to changing market demands.

transcoding technical

"moving transcoding operations in-house, Czech TV gains greater control"

Transcoding is the process of converting digital audio or video files from one format, size, or quality level to another so they play correctly on different devices and network speeds. For investors, it matters because transcoding determines how efficiently a media or cloud company delivers content, influencing streaming quality, bandwidth and storage costs, scalability, and end-user experience — all of which affect revenue and margins.

hbbtv technical

"support mobile, web app and HbbTV delivery"

HbbTV is a technical standard that blends traditional broadcast television with internet-delivered content and interactive features, letting viewers access live channels, on‑demand video, apps and supplementary information on the same TV. Like turning a conventional TV into a connected device, it lets broadcasters, platform operators and advertisers add subscription services, targeted ads and viewer data, creating new revenue opportunities and shifting how TV audiences are measured and monetized.

descriptive audio technical

"audio mixing capabilities for the delivery of descriptive audio for impaired audiences"

Descriptive audio is an additional soundtrack that narrates the important visual elements of a video or broadcast — for example, setting, action and on-screen text — so people who are blind or have low vision can follow along. For investors it matters because offering this accessibility feature can expand audience reach, reduce legal and regulatory risk, and signal inclusive practices that affect reputation, customer base and potential revenue.
