Introduction

After publishing your video and/or audio content to your store (website, app), your major concern is whether the content is secure or not. There are chances that someone might download and misuse your content if it is not protected or secured. Consequently, there are various methods available to protect digital content so that no one can copy or download the content unauthorizedly and misuse it. One such method is implementing DRM or Digital Rights Management. DRM is implemented by inserting code that stops copying, limits the number of devices the content can be accessed on, or specifies a time in which the content can be accessed. Muvi's Multi-DRM solution provides license management features for multiple DRM formats such as Widevine, PlayReady, and FairPlay and enables you to deliver content securely over the browser, mobile devices, set-top boxes, and more. Even your live streaming content is encrypted and broadcasted to users who have authentic access to your live events.

How to Enable DRM

You can enable DRM for video while adding a video encoding profile. You can also edit an existing encoding profile and enable the DRM. When you are creating content, select the profile where you have enabled the DRM option. The video will automatically get encoded with DRM.

• To add a DRM-enabled video encoding profile, navigate to “Player”-->” Encoding Profiles” in the CMS.
• Click on "Add Profile" in the top right corner.
• Type a profile name (e.g., DRM, ).
• Select the “Source Type” for the video.
• Select DRM (Digital Rights Management) and then select “Yes”. If you select “Yes” then the video will be encoded with DRM.
• Select the *“Output Formats” (i.e., MPEG DASH, HLS)
• Select the “Output Resolution” (i.e., 3840x2160(4K), 1920x1080(1080p), etc.) you can select multiple resolutions. The video will be encoded and stored in the resolution you will select. To learn more about encoding resolutions click here.
• Click on “Save”.
• You can also edit an existing encoding profile and enable/disable DRM for that profile.

How DRM Works

At Muvi, your content is protected by the DRM. The DRM technology ensures that the video is in an encrypted format (i.e. MPEG-DASH or HLS [.m3u8]) and available in parts so that the complete video/audio can’t be accessed in one file. Here, the Bento4 tool is used to convert MP4 video to MPEG-DASH. Even if someone downloads some parts of the video, he/she can’t play the video as it requires a License key to play the content. To decrypt the video, the downloader needs 2 things - Content Unique Key & License Key. The Token generated is device-specific, which means, the token generated for one device won’t work on another.

• At Muvi, we use industry-standard DRMs including Google Widevine, Apple FairPlay, and Microsoft PlayReady. Google Widevine is used in Chrome, Microsoft Playready in IE & Edge browser, and Apple FairPlay is used in the Safari browser.
• The license key is unique for each DRM account. The content key is unique for each content. Once encoding is completed, we upload the video to the respective S3 bucket. This file format is.MPD.
• End-user browses content to play with Muvi’s proprietary HTML5 Player. The player contains the Amazon Cloud front CDN URL for the content. CDN URL points to the packaged MPEG-DASH video stored in the respective S3 bucket.
• When the end-user browses for the content, we select which DRM license to use depending on the end-users browser. Client DRM processes the license key & plays the content if authentication is successful.

Testing DRM

If you want to test whether your content is DRM enabled or not, then try to download the content in the Firefox browser. It will show you a warning message that the content is DRM enabled and you cannot download it. You can also ask us to send you.MPD file and.MPEG-DASH stream. You won’t be able to play the videos as they will be encrypted. You will be able to play videos only inside our player as it has the decryption client.

Testing DRM-Supported Devices

To find out whether a device supports DRM-enabled content or not, you can try to play this Test Link on that specific device. If the content is played seamlessly on that device, then it supports DRM-enabled content.

DRM Supported Platforms

We support DRM content for the below-listed platforms.

Multiple DRMs per OS & Browser

For different types of Operating Systems (OS) and Browsers, different DRMs are available. Below is the list of different Operating Systems and Browsers and supported DRMs for them.

DRM Supported OS & Browsers

Below is the list of Operating Systems and Browsers that support DRM.

DRM Support in Mobile Browsers

Features Not Supported in the DRM Player

The DRM player doesn't support certain features that are supported in the Non-DRM player.

• Resolution - Users are not able to change the resolution on a DRM player. While playing the DRM content, the player doesn't show the gear icon to select and change the resolution.
• Flash Player Functionality - is not supported in the DRM player.
• Back Button, Resume Watch, AutoPlay, and Play Duration features are not supported in the DRM Embed Player, Preview Player, and Social Share Player. However, these features are supported in the Frontend DRM player.

How to Disable DRM

If you wish to disable DRM for your store, you need to add a Support Ticket. Once the DRM is disabled for your store, we will have to encode all the videos in your store manually. It may take a few days to weeks to encode all the videos depending on the size and number of videos.

DRM Prevents Screen Capturing

DRM prevents screen capturing. When someone tries to screen record or take a screenshot of a DRM-protected video (on a laptop/desktop), it will not allow doing that and captures only a black screen (see the below screenshot). However, screen capturing for DRM-enabled video is possible on all mobile apps.

Browsers that Prevent Screen Capturing

The below list shows which browsers prevent screen capturing (in all devices including laptop, desktop, and mobile devices) and which doesn't.
