Essential technology for video streaming services includes a combination of content delivery networks (CDNs), encoding, and adaptive bitrate streaming techniques. CDNs enable efficient distribution of video content over the internet, minimizing latency and ensuring smooth playback. Encoding compresses video files for optimal quality and performance across various devices. Adaptive bitrate streaming adjusts video quality based on the user’s internet connection, enhancing the viewing experience. Together, these technologies facilitate high-quality, seamless streaming, enabling platforms like Netflix and YouTube to deliver content efficiently to millions of users worldwide.
