Whenever you hit play on a video, whether it’s Netflix, YouTube, a live sports match, or even a video call, something happens quietly in the background that makes sure the video actually reaches you.

Think of it like the delivery method for video. It decides how the content is chopped into chunks, how it’s sent, and how it’s reassembled smoothly on your device. Without the right protocol, videos would buffer endlessly, lose quality,…

Best Video Aspect Ratio & Dimensions for YouTube, Instagram, etc
In the year 1997, my friend's father bought their first television set with a wider screen.

Introduction to Encrypted Media Extensions (EME) For DRM Systems
Encrypted Media Extensions is a JavaScript API that enables content protection for premium videos in the browser. EME is important in how a DRM system works. EME API is a W3C-recommended standard, meaning that streaming media applications are interoperable across different browsers irrespective of the underlying DRM system. The cryptographically trusted agent of DRM systems inside browsers is the Content Decryption Module (CDM). The CDM works by receiving the content keys from the remote DRM License Server. The Content Decryption Module then uses the content keys to decode encrypted videos for playback. Streaming media applications use the EME API to…
