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…

Video Metadata – Optimize to Increase Your Viewers
What is Metadata? Metadata is text inside the video file that references the video. Search engines use video metadata to show video results. YouTube combines video metadata with other video viewership data to determine when to show videos among its top results. Likewise, Content recommendation systems, such as Netflix's famous machine learning algorithms, also use video metadata to accurately personalize videos. How is Video Search different from Web Page Search? The beasts of burden of the internet are the web bots that crawl every single page there is. Web crawlers determine the suitability of a page for search results on two…
A Business & Entertainment History of Streaming Media

A Rolling Stone Live Concert was broadcast live from Cotton Bowl in Dallas on 18 November 1994. Knowing the broadcast channel to be live…
