Streaming channel settings

Available in Classic and VPC

You can quickly and easily build the VOD streaming service customers want by utilizing the video files stored on Object Storage. You don't need expert knowledge on VOD streaming. With just a few steps, you can automatically create CDN for the service in the optimal environment.

Create channel

To create a channel for VOD streaming:

1. From the NAVER Cloud Platform console, navigate to > Services > Media > VOD Station.
2. Click the Channel menu and click [Create channel].
3. Enter a channel name and set each item.
   • If there is no created Object Storage bucket, create an Object Storage bucket.
     • Bucket names cannot contain hls and dashes.
   • VOD Station supports automatic creation by integrating with Global Edge. For more information on Global Edge settings, see Global Edge user guide.
     • To create Global Edge, you must select a Global Edge profile. If you don't have a Global Edge profile, create one on Global Edge.
     • Select the main country for the service.
   • For more information on encryption settings for content protection, see Content protection settings.
4. When you finish setting up, click [Create channel].
5. Check the settings in the confirmation popup and click [Create channel].

Content protection settings

You can set media encryption and DRM features from the Content protection settings component on the Create channel interface. For encryption type and supported devices by media encryption and DRM technology, see the following table.
Check the link here to learn more about other platforms and versions.

| Encryption type | Protocol | DRM type | Encryption algorithm | Supported devices |
|--- |--- |--- |--- |--- |
| HLS AES-128 | HLS | - | AES-128 | MS Edge, Internet Explorer 11, Google Chrome, Firefox, Opera HLS HTML5 |
| DRM | HLS | FairPlay | SAMPLE-AES | 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 |

Media Encryption

Media encryption is applied to the HLS protocol, and encryption is automatically performed on each HLS TS file using the AES-128 method.
The URL to obtain the key is displayed on the manifest. You can use the security token of the CDN to improve your security level.
This feature is part of the HLS standard and is automatically decrypted by any player that supports HLS.
However, media encryption cannot be configured together with FairPlay.

Multi DRM

VOD Station provides Multi-DRM in collaboration with DoveRunner (formerly PallyCon), a globally proven content security provider that ensures high performance and stability. By supporting standard DRMs such as Widevine, FairPlay, and PlayReady, it enables you to apply strong security to any video without limitations imposed by operating systems or platforms.
External DRM can be integrated with DoveRunner (formerly PallyCon) DRM CPIX API v1, but integration with other providers may not work properly. Only single-key packaging is supported.

One Click Multi DRM

• Multi DRM: Select the DRM you want to use as One Click Multi DRM.
• DRM Site: Select the site to use.
  • Through integration with the Multi DRM service provided by NAVER Cloud Platform, DRM can be applied.
  • To use DRM, you must first proceed with creating a site within the One Click Multi DRM service.
  • When the selected DRM Site is enabled, you can use the DRM feature properly.
• Content ID: The Content ID is a unique identifier for the content to be played and is used during DRM packaging.

External DRM

• Multi DRM: Select the DRM you want to use as an external DRM.

• DRM type: Select the DRM technology you want to use.

  • FairPlay: DRM technical specifications provided by Apple. It encrypts each HLS segment by using Sample-AES method.
  • Widevine: DRM technical specifications provided by Google. It uses the AES-128 method for encryption according to the common encryption specifications.
  • PlayReady: DRM technical specifications provided by Microsoft. It uses the AES-128 method for encryption according to the common encryption specifications.

• Content ID: A unique identifier for DRM-packaged content, and the Content ID value that must be included in the XML body when making a CPIX API request.
  Example: drm-contents

• DRM System ID: A unique identifier for the DRM system, and the System ID to be included in the XML body when making a CPIX API request. Depending on the selected encryption configuration, 1 or 2 System IDs must be provided. Enter 1 System ID per line.
  Example:
  9A04F079-9840-4286-AB92-E65BE0885F95
EDEF8BA9-79D6-4ACE-A3C8-27DCD51D21ED

• DRM Key URL: The CPIX API request URL. Enter the value according to the encryption key request format required by your DRM provider.
  Example: https://kms.example.com/cpix/v1/key/ujllldopmquy==
