HLS is Apple's adaptive streaming protocol: video is split into short segments listed in m3u8 playlists, and the player switches quality based on bandwidth. It is required for Apple devices and works everywhere else. Security-wise it is neutral, carrying anything from unencrypted segments to AES-128 to full FairPlay DRM.

MPEG-DASH is the international-standard counterpart to HLS: adaptive segmented streaming described by an XML manifest (MPD). It is the usual carrier for Widevine- and PlayReady-protected content on Chrome, Firefox, Edge, Android, and smart TVs, using CENC encryption. Safari and iOS do not support DASH natively.

CMAF is a standardized media container that lets a single set of encoded, encrypted segments serve both HLS and MPEG-DASH. Using CENC in CBCS mode, one CMAF encode can be delivered to Apple devices via HLS and to others via DASH, reducing storage and simplifying multi-DRM packaging.

A content delivery network is a globally distributed set of servers that cache and deliver video from locations near each viewer, reducing latency and buffering. For video platforms the CDN handles scale and speed, while protection comes from the encryption, DRM, and access controls layered on top of it.

Video hosting is a service that stores, processes, and delivers video for playback on websites and apps, handling upload, transcoding, and CDN streaming. General video hosting optimizes for reach, sharing, or marketing; secure video hosting adds DRM, watermarking, and access control for premium, paywalled content.

An M3U8 is the playlist file used by HLS to list a video's segments and quality renditions. Players read it to fetch and play segments in order. Because a plain M3U8 exposes segment URLs, unprotected or AES-128 streams described by one can be captured by download tools unless DRM and token-based playback are applied.

Live streaming delivers video to viewers in real time as an event happens, rather than from a stored file. It adds challenges over VOD, including low latency and no chance to pre-process, and faces restreaming piracy. Protecting live streams uses DRM, tokenized access, concurrency limits, and watermarking applied in real time.

ExoPlayer, now part of AndroidX Media3, is Google's open-source media player library for Android. It supports adaptive streaming (HLS, DASH) and Widevine DRM playback, and honors the FLAG_SECURE flag to block screen capture, making it the standard foundation for secure video playback in Android apps.

AVPlayer is Apple's built-in media player framework for iOS, iPadOS, macOS, and tvOS. It plays HLS streams and integrates Apple FairPlay Streaming DRM through AVContentKeySession, making it the standard foundation for secure protected video playback on Apple devices.

Encryption is the process of scrambling the video file, so that the video can only be played using the authorized content keys
