Non-compliant content may expose your business to legal risks and hurt your brand. VOD offers audio/video moderation and image moderation capabilities to help you ensure the compliance of your content.
Audio/Video Moderation
The audio/video moderation feature of VOD analyzes your video and audio content and gives suggestions on whether to publish or block the content.
You can initiate audio/video content moderation in the following two ways:
1. Initiate it in the VOD console.
Using a server-side API to initiate audio/video moderation
The figure below shows how a video application moderates the videos uploaded by users using the server-side API.
1. The video application backend authenticates the content provider and distributes a signature for upload from client.
2. The content provider uploads the content to VOD.
3. VOD sends information including the file ID and playback URL of the uploaded video to the application backend.
4. VOD executes a moderation task (
ReviewAudioVideoTask) according to the procedure parameter passed in when the video is uploaded.5. VOD sends the result to the application backend via the ReviewAudioVideoComplete notification.
If the moderation result is "block", there’s a high chance that the content is non-compliant. We recommend you block the content.
If the moderation result is "pass", the probability of the content being non-compliant is low. We recommend you allow the content to pass.
If the moderation result is "review", the probability of the content being non-compliant is high; in this case, manual verification is recommended.
6. The application backend publishes videos whose suggestion is "pass" as well as those that are given a "review" suggestion and have passed manual verification.
7. Viewers request a playback URL for a published video from the application backend.
8. Viewers play the video via the URL (VOD offers acceleration services).
Steps 4-6 ensure that the video obtained in step 7 is compliant.
Note:
In the above process, videos are moderated before being published (only videos that pass the moderation or review are published). You can also use the post-moderation mode, in which videos are published first before moderation is performed (non-compliant content detected will be removed).
Image Moderation
The image moderation feature of VOD analyzes images and gives suggestions on whether to pass or block them. Unlike audio/video moderation, image moderation is performed synchronously, and results are generated immediately.
If the moderation result is "block", there's a high chance that the content is non-compliant. We recommend you block the content.
If the moderation result is "pass", the probability of the content being non-compliant is low. We recommend you allow the content to pass.
If the moderation result is "review", the probability of the content being non-compliant is high; in this case, manual verification is recommended.
You can initiate image moderation in two ways:
1. Initiate it in the VOD console.
2. Call the server-side API ReviewImage.
