Thank you for your feedback
This is an API that creates Live Station channels. Channel list search API and Channel information search API are provided to search the created channels.
Note
The following are precautions when creating channels.
- If you are using a streaming redundancy setting, you must stream the main stream first.
- If you need to create LL-HLS channels, you must utilize the quality set for low latency.
- The full version of LL-HLS is only supported in Global Edge CDN integration environments.
- If you are using an existing CDN, you need to renew the previously created CDN. See the User Guide for instructions on how to renew CDNs.
- We recommend setting the keyframe to 1 second for seamless LL-HLS channel usage. See the User Guide for detailed streaming instructions.
- Live Station supports easy integration with One Click Multi DRM, and only supports single-key packaging.
- Channels using quality settings that include passthrough quality do not support DRM encryption.
Note
The following are precautions when using the content authentication (Signed URL/JWT) control of Global Edge in integration with Live Station.
- You must set Edge Auth to the outputProtocol of the channel that created Edge Auth in the cache settings of Global Edge. For more information on how to change Global Edge Edge Auth settings, see the API Guide.
- Extensions excluded from authentication
- HLS: .ts, .jpg
- HLS, DASH: .ts, .jpg, .m4s, .m4v, .m4a
- LL_HLS: .jpg, .m4s, .m4v, .m4a
- Extension that forwards the authentication token to the source
- HLS: .m3u8
- HLS/DASH: .m3u8, .mpd
- LL_HLS: playlist.m3u8
- Extensions excluded from authentication
- When issuing an authentication token, you must enter wildcard path under acl for Signed URL and path for JWT respectively. For more information on how to issue authentication tokens, see the User Guide.
- wildcard path: '/live/video/{channelId}/*'
Set content protection
Live Station DRM Encryption supports multi-DRM for real-time content.
You can easily set the DRM feature in the DRM settings area in the channel creation, and it supports multi-DRM encryption depending on the selected OutputProtocol.
For more information about encryption methods by DRM technology and supported devices and other platforms and versions, see this link.
| Encryption type | Protocol | DRM type | Encryption algorithm | Supported devices |
|--- |--- |--- |--- |--- |
| DRM | HLS | FairPlay | AES-CBC | Mac/iOS Safari browser, iOS/iPadOS/tvOS app, HLS HTML5 |
| DRM | DASH | PlayReady, Widevine | CENC (Common Encryption) | MS Edge, Internet Explorer 11, Google Chrome, Firefox, Opera DASH HTML5 |
- DRM type
- FairPlay: A DRM technology protocol provided by Apple. It encrypts each HLS segment with the AES-CBC method.
- Widevine: A DRM technology protocol provided by Google. It encrypts with the AES-128 method according to the Common Encryption Standard.
- PlayReady: A DRM technology protocol provided by Microsoft. It encrypts with the AES-128 method according to the Common Encryption Standard.
