Core playlist terms
| Term | Plain meaning | Why it matters |
|---|---|---|
| M3U8 | A UTF-8 playlist format commonly used by HLS. | The playlist points the browser or player to media playlists, variants, and segments. |
| HLS | HTTP Live Streaming, a video delivery method using playlists and segments. | It supports adaptive playback but introduces browser, CDN, and access-rule checks. |
| Master playlist | A playlist that lists multiple stream variants. | A master playlist can load while one selected variant still fails. |
| Media playlist | A playlist that lists the actual media segments. | Segment paths, timing, and key references are checked here. |

Access and browser terms
- CORS: browser cross-origin rules that decide whether JavaScript playback may read remote playlists and segments.
- 403 Forbidden: an access-control response. It usually means the owner-side policy must be fixed, not bypassed.
- Signed URL: a temporary URL with a token or signature. Treat it like a short-lived credential.
- DRM: a rights-management layer. This site does not bypass DRM or private access controls.
- Codec: the audio or video encoding format. A playlist can load while the browser cannot decode the selected media.
