Channel (Distribution Unit) Settings

Notice

This document is a machine-translated draft and is currently undergoing review. Some content may be inaccurate or differ from the original Korean version. For the most precise information, refer to the Korean documentation.

Channel is a logical unit in Kollus VOD for exposing and distributing content externally. When a specific content is registered to a channel, a Media Content Key, which is a unique identifier dedicated to that channel, is generated. Customers can create Playback URLs based on the generated key or integrate with their own systems via API.

Channel operation policies​

When creating a channel, you must select a policy according to the security level and business purpose of the content to be distributed.

Caution

Core security policies cannot be modified after a channel is created. For example, it is not possible to convert a standard channel to an encrypted-only channel while it is in operation. If a policy change is required, a new channel must be created.

Sharing policy​

  • Shared channel: Provides a Share URL and embed code for external distribution.
  • Non-shared channel: No Share URL or embed code for external distribution is provided; a JWT(JSON Web Token)-based secure URL must be configured instead.

Security policy​

  • Encrypted channel (Kollus DRM Only): Only content with Kollus DRM applied can be registered. (Learn More: Content Encryption (DRM))
  • Standard channel (unencrypted): The default channel where all content can be registered regardless of encryption status.

Create a new channel​

Create a channel that defines the distribution method and viewing environment for content. The channel serves as the basis for determining the distribution method, security policy, and streaming specifications.

  1. Go to Kollus VOD console > [Channel].
  2. Click [Add (+)] at the top of the channel list on the left, or click [Add channel] in the upper right.
  3. Configure the following items according to the nature of the channel.
    Caution

    Channel settings items cannot be modified after saving.

    ItemDescription

    DescriptionEnter the purpose or management intent of the channel

    Delivery methodStreaming and file delivery specifications (Encrypted content-only channels support Progressive Download only.)
    • [Progressive Download]: Sequential download method (for low-spec environments)
    • [HLS]: Automatically optimizes video quality based on network conditions
    • [HLS (AES-128)]: Enhanced security (adds AES-128 encryption layer)
    Security settings
    • [Block playback when manipulating video watermark]: Immediately blocks playback when watermark tampering is detected
  4. After completing the settings, click [Save] to create the channel.

Register content to a channel​

This is the step of mapping content to a specific channel to make it ready for playback. The channels available for registration are restricted depending on the security status of the content.

Content security statusAvailable channel types
Standard content (unencrypted)Can be registered to all types of channels
Encrypted content (Kollus DRM applied)Can only be registered to encrypted-only channels

Method 1: register from library​

This is the most efficient method when distributing multiple pieces of content scattered across various categories to a single channel simultaneously.

  1. Go to Kollus VOD console > [Library].
  2. Click the checkbox to the left of the content to select it. (Multiple selections allowed)
  3. Click [Register channel] in the bottom toolbar.
  4. Select a channel and click [Save].

Method 2: register from channel​

This is suitable when searching for and selecting the necessary content from the perspective of a specific channel.

  1. Click the target channel in Kollus VOD console > [Channel].
  2. Click [Add content to channel] in the upper right.
  3. Click the checkbox to the left of the content to select it. (Multiple selections allowed)
    • Precise filtering: Click the filter icon in the upper left to filter content by encoding status, encryption status, and more.
  4. After completing your selection, click [Add].

Remove content from a channel​

Removes content from the channel. The content is preserved in the library, but the existing media content key expires immediately, invalidating all playback links created with that key.

  1. Go to Kollus VOD console > [Channel] > target channel.
  2. Select the checkbox of the content to remove from the channel.
  3. Click [Remove from channel] in the bottom toolbar.
Caution

Clicking [More options (⋮)] > [Delete content] on the right side of the content does not just remove it from the channel — it permanently deletes it from the library as well.

Edit a channel​

You can change the channel name, description, streaming delivery method, and more to suit operational needs.

  1. Go to Kollus VOD console > [Channel].
  2. Click [More options (⋮)] > [Edit channel] in the left channel list or on the channel card.
  3. Modify the necessary items and click [Save].
    Items that cannot be modified

    Channel settings items cannot be modified after saving.

Disable a channel​

Use this when you want to immediately block user access while retaining the content data. When a user accesses the URL of a disabled channel, the following message is displayed.

Error occurred while loading content. Please apply to your content provider.

  1. Go to Kollus VOD console > [Channel].
  2. Click [More options (⋮)] > [Disable channel] in the left channel list or on the channel card.
  3. Review the guidance message in the disable dialog and click [Disable].
Enabling a Channel

Click [More options (⋮)] > [Enable channel] on a disabled channel to immediately resume distribution.

Delete a channel​

Permanently deletes a distribution path that is no longer in use. Be sure to understand the technical impact before deleting.

Technical impact of deleting a channel
  • Content preservation: Deleting a channel does not delete the original content stored in the library.
  • Media content key expiration: All media content keys that were issued through the deleted channel expire immediately. As a result, all Playback URLs and API integration services created based on those keys will be discontinued.
  • Redistribution required: To serve the same content again, you must register it to a new channel to issue a new media content key.
  1. Go to Kollus VOD console > [Channel].
  2. Click [More options (⋮)] > [Delete channel] in the left channel list or on the channel card.
  3. Review the guidance message in the delete dialog and click [Delete].
