One of the reasons for this is that their content is protected from piracy by Widevine <a href=\"https:\/\/www.vdocipher.com\/blog\/drm-technology\/\">DRM technology<\/a> and only devices with higher security compatibility are allowed to stream the best quality content.<\/p>\n<p>You might be wondering, what Widevine is? Find out all about Widevine DRM, its security levels, compatibility, how it works, and more in this article.<\/p>\n<h2 id=\"1\"><b>What is Widevine DRM?<\/b><\/h2>\n<p>Widevine DRM is a widely used DRM licensing and encryption technology owned and maintained by Google. It protects your videos from being downloaded illegally on browsers such as Chrome, Firefox, and Edge. It also protects content on devices such as\u00a0 Android devices, Android TV, and Chromecast. Widevine DRM is compatible with streaming by <a href=\"https:\/\/www.vdocipher.com\/blog\/mpeg-dash\">MPEG Dash<\/a> and <a href=\"https:\/\/www.vdocipher.com\/blog\/2017\/08\/hls-streaming-hls-encryption-secure-hls-drm\/\">HLS<\/a>. It\u2019s used by major streaming services (Netflix, Prime Video, Disney+, HBO Max, YouTube, etc.).<\/p>\n<p>One of the main reasons several OTT and e-learning platforms use Widevine DRM is to ensure they earn maximum revenues from their content by restricting illegal free distribution of their content due to video piracy.<\/p>\n<h2 id=\"2\"><b>History Of Widevine DRM<\/b><\/h2>\n<p>Originally Widevine was a separate company from Google working on securing online videos on its own, till it was acquired by\u00a0 Google.<\/p>\n<p>Widevine technologies initially worked on digital rights management software which replaced smart cards based content security. This changed a lot of things as the cost of the card was removed along with the overall logistics involved with the distribution of the card.<\/p>\n<p>In 2010 Widevine was purchased by Google, in order to improve their support for media and entertainment <a href=\"https:\/\/www.vdocipher.com\/blog\/2021\/02\/online-video-platform-guide\/\">video platforms<\/a>. This further helped them speed up <a href=\"https:\/\/www.vdocipher.com\/blog\/2022\/06\/drm-streaming\/\">DRM encrypted video streaming<\/a> on android with the help of <a href=\"https:\/\/www.vdocipher.com\/blog\/adaptive-bitrate-streaming\">adaptive streaming<\/a>.<\/p>\n<p>Widevine has two different versions, i.e. classic and modular.<\/p>\n<h3><b>Widevine Classic<\/b>:<\/h3>\n<p>Widevine Classic is the older version and it is only currently available for legacy devices such as older Android devices and smart TVs. It required that the content is in their proprietary .wvm format.

Otherwise, you can just jump on to the next section using this link.<\/p>\n<p>DRM or Digital Rights Management is a way to protect your content from any unauthorized use. You can set restrictions on the use of your video so that you have complete control over who accesses it.<\/p>\n<p>Video DRM solutions protect your content by keeping the encryption key for the content safe. Usually, even with strong encryption, videos were easily downloaded by various tools, as they were able to identify the key and used it to download the videos. With DRM, you can\u2019t access the key as it is hidden in a BlackBox setup called CDM.<\/p>\n<p>Another key DRM is Apple&#8217;s <a href=\"https:\/\/www.vdocipher.com\/blog\/fairplay-drm-ios-safari-html5\/\">Fairplay DRM<\/a> and is used along with Widevine DRM.

Here the security is at the hardware level. Most modern Android devices support Widevine L1 but still, there are a considerable number of devices with L3 security.<\/p>\n<p>Many movie platforms like Netflix purposefully restrict full HD playback to only L1 devices. This is due to the fact that L1 devices can block screen capture with 100% security in mobile apps.<\/p>\n<p>Though this decision of basing the quality of video on Widevine security level, is a sole choice of platform\/content provider and there are no compulsory rules around it. Many other movie platforms and course video websites\/apps provide HD playback in all security levels.<\/p>\n<p>For Widevine L1, TEE does all the video decryption, decoding, and processing.<\/p>\n<p>Widevine L1 uses hardware-based security features and trusted execution environments (TEE) to ensure the highest level of security against unauthorized access and content piracy.<\/p>\n<p>Devices that support Widevine L1 have specialized security hardware that enables the decryption and playback of encrypted content within a secure environment.<\/p>\n<p>This makes it extremely challenging for hackers and unauthorized parties to intercept or tamper with the protected content.<\/p>\n<p>This is why, Widevine L1 is being widely used to stream premium content.<\/p>\n<h3><b>Widevine L2<\/b><\/h3>\n<p>In Widevine L2 only video decryption happens in TEE, while video processing happens out of TEE.<\/p>\n<p>It is not used for mobile devices. Widevine L2 isn\u2019t really \u201cused\u201d on mainstream consumer devices anymore. It is mainly on legacy or low-cost smart TVs, Custom Android builds \/ embedded systems and Prototype or transitional hardware.<\/p>\n<h3><b>Widevine L3<\/b><\/h3>\n<p>Widevine L3 is the first level of Widevine security. L3 Devices don\u2019t have TEE, and the protection here is only software-based. Many old phones, especially budget phones have L3.<\/p>\n<p>It provides a moderate level of protection and is usually there on lower-end devices. Standard-definition content is usually streamed on devices using Widevine L3. Although being the least secure Widevine version, it does provide some encryption and content protection<\/p>\n<p>Widevine L3 is usually available on mid-range and lower-end smartphones, older smart TVs, and other budget-friendly devices and is available to a broader audience. But with its lower security, it can be susceptible to various vulnerabilities and attacks as it lacks the hardware-backed security features of Widevine L1.<\/p>\n<p>This is why in order to address this vulnerability, content platforms usually stream their higher-quality content on Widevine L2 or Widevine L1 devices.<\/p>\n<h2><b>Widevine L1 vs L3: Difference between the two Widevine security levels<\/b><\/h2>\n<p>The major differences between Widevine L1 and Widevine L3 is the security and content protection they offer.<\/p>\n<p>Security Level:<\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\">Widevine L1:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">\u00a0Widevine L1 is the highest security level.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Robust encryption and hardware-based security measures<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\">L1 is designed for devices that have trusted execution environments (TEE)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Widevine L3:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Widevine L3 is the lowest security level among the Widevine options.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Basic level of encryption and content protection<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Device Compatibility:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\">Widevine L1:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">\u00a0Widevine L1 is supported on higher-end devices with dedicated security hardware like premium smartphones, smart TVs, and certain streaming devices.<\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"2\">Widevine L3:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Widevine L3 is more widely compatible with various devices, including mid-range and lower-end smartphones, older smart TVs, and other budget-friendly devices.<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"3\">It can operate on a broader range of hardware since it doesn&#8217;t require specialized security hardware like Widevine L1.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">Content Resolution:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\">Widevine L1:\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Widevine L1 enables the playback of high-definition (HD) and 4K content with full resolution and quality.<\/li>\n<\/ul>\n<\/li>\n<li>Widevine L3:\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"3\">Widevine L3 is suitable for protecting standard-definition (SD) content and lower-quality media streams.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2 id=\"5\"><b>Google Widevine DRM Compatibility<\/b><\/h2>\n<p>Now that we\u2019ve gone through the security levels and know what devices support which level of security.

Widevine DRM is an essential component of any multi-DRM strategy for premium content.<\/p>\n<h2 id=\"6\"><b>How Does Google Widevine DRM Work?<\/b><\/h2>\n<p>There\u2019s a lot that goes on behind the scenes when you click \u2018play\u2019 on a video and when you are finally able to see it.<\/p>\n<p>In Widevine DRM, secure decryption is done via a series of exchanges between the Content Decryption Module and the <a href=\"https:\/\/www.vdocipher.com\/page\/widevine-drm-license-server\">Widevine DRM license server<\/a>.\u00a0 The <a href=\"https:\/\/www.vdocipher.com\/blog\/2020\/09\/online-video-player-html5-website\/\">HTML5 video player<\/a> acts as a mediator for these exchanges. Although, by itself, the player cannot read the encrypted license.<\/p>\n<p><a href=\"https:\/\/www.vdocipher.com\/blog\/wp-content\/uploads\/2025\/07\/widevine-workflow.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-9549\" src=\"https:\/\/www.vdocipher.com\/blog\/wp-content\/uploads\/2025\/07\/widevine-workflow.png\" alt=\"Widevine DRM playback security model\" width=\"1024\" height=\"768\" \/><\/a><br \/>\nWhen you click \u2018play\u2019 on an encrypted video, a secure sequence is triggered between the <strong>HTML5 player<\/strong>, the <strong>Content Decryption Module (CDM)<\/strong>, and the <strong>Widevine license server<\/strong> to ensure protected playback. Here\u2019s how it works:<\/p>\n<h3>Step-by-step Process:<\/h3>\n<ol>\n<li>\n<h4>Encrypted Video from CDN<\/h4>\n<p>The video file is delivered from the Content Delivery Network (CDN) in CENC encrypted format (usually MP4 or DASH segments). The browser\u2019s media engine identifies that the content is encrypted and triggers an <code>Encrypted<\/code> event.<\/li>\n<li>\n<h4>Player Sends Initialization Data to CDM<\/h4>\n<p>The browser extracts <code>initData<\/code> from the media file \u2014 this includes encryption metadata like PSSH boxes (Protection System Specific Header). This <code>initData<\/code> is passed by the HTML5 player to the Content Decryption Module (CDM) using Encrypted Media Extensions (EME) APIs.<\/li>\n<li>\n<h4>CDM Creates License Request<\/h4>\n<p>The CDM generates a license request based on the <code>initData<\/code>. This request includes the device&#8217;s credentials and a session ID. The player forwards this request (without reading its contents) to the application server or license proxy.<\/li>\n<li>\n<h4>License Server Receives the Request<\/h4>\n<p>The request is sent to the Widevine License Server, which validates:<\/p>\n<ul>\n<li>User authentication<\/li>\n<li>Playback rights (resolution, expiration, etc.)<\/li>\n<li>Device security level (L1, L2, L3)<\/li>\n<\/ul>\n<\/li>\n<li>\n<h4>License Response Sent Back to CDM<\/h4>\n<p>The license server responds with a signed, encrypted license blob. The app or player sends this blob back to the CDM without parsing or decrypting it.<\/li>\n<li>\n<h4>CDM (and OEMCrypto if L1) Decrypts the License<\/h4>\n<p>The CDM receives the license, parses it, and extracts decryption keys. If the device supports Widevine L1, the decryption keys are passed to the OEMCrypto module running inside a Trusted Execution Environment (TEE). On Widevine L3 devices, CDM handles decryption in user space.<\/li>\n<li>\n<h4>Decryption and Playback<\/h4>\n<p>As encrypted video chunks arrive, the CDM (with or without OEMCrypto) decrypts them securely. Decrypted frames are passed directly to the secure video pipeline. The HTML5 player controls playback (play, pause, seek), but never gains access to raw video data.<\/li>\n<\/ol>\n<p>Now that you are aware of how Widevine DRM works, let&#8217;s have a look at its implementation. Having implemented Widevine DRM for more than 2000 customers, we can claim that<\/p>\n<h2><b>How Do The Widevine DRM Components Flow Together As A Platform?<\/b><\/h2>\n<p>Widevine\u2019s DRM components work together with each other in order to provide you with an end to end solution for protecting your video content.

This ensures that users have the best HD streaming experience while keeping the revenue interests of the content provider at the front.<\/p>\n<div style=\"padding-top: 62%; position: relative;\"><iframe style=\"border: 0; max-width: 100%; position: absolute; top: 0; left: 0; height: 100%; width: 100%;\" src=\"https:\/\/player.vdocipher.com\/v2\/?otp=20160313versUSE31317xglXjw5nAEghrcO0ierB7eRzfz5bAr9umo94LVbd7zYL&amp;playbackInfo=eyJ2aWRlb0lkIjoiMzBkN2I2ODliYjRiNDA5YWExMTkwMTg5MTRlNTQzNjQifQ==\" allowfullscreen=\"allowfullscreen\" allow=\"encrypted-media\"><\/iframe><\/div>\n<p>At VdoCipher we have incorporated the Widevine architecture as part of our streaming infrastructure. It includes transcoding and encryption, adaptive streaming, and communication with the <a href=\"https:\/\/www.vdocipher.com\/blog\/drm-server\/\">DRM server<\/a> for secure decryption.<\/p>\n<p>The ultimate endorsement for any Digital Rights Management system is having certifications from Hollywood studios. They have millions of dollars on the line when they make their content available via online streaming. Hollywood\u2019s Digital Entertainment Content Ecosystem (DECE) endorses Widevine\u2019s DRM for streaming videos. Netflix and Amazon Instant Video use Widevine DRM for streaming on Chrome and Android devices. At VdoCipher our aim is to provide a complete video streaming solution that handles everything from user experience to content protection for our users. In this blog, I detail how VdoCipher makes Widevine available for all users.<\/p>\n<ul>\n<li><strong>Video Upload<\/strong> &#8211; You can upload videos through the dashboard, or using our upload APIs<\/li>\n<li><strong>Video Processing<\/strong> &#8211;\n<ul>\n<li>Encoding &#8211; Videos are encoded at multiple bitrates<\/li>\n<li>File encryption (using CENC).<\/li>\n<li>Video File packaging and Key generation from the DRM license server<\/li>\n<\/ul>\n<\/li>\n<li><strong>Video Management using APIs<\/strong><\/li>\n<li>Encrypted video files are stored on Amazon Cloudfront and Google Cloud Platform CDN Edge locations to ensure fast video streaming<\/li>\n<li><strong>Video player customizations<\/strong>\n<ul>\n<li>Player theme change<\/li>\n<li>Overlays\/buttons over video<\/li>\n<\/ul>\n<\/li>\n<li><strong>Secure Video playback<\/strong>\n<ul>\n<li>Embed Code to generate Dynamic URLs (HTTP Post request including client secret key to get unique OTP)<\/li>\n<li>Unique OTP is then sent by the DRM license server<\/li>\n<li>Encrypted video file is decrypted in Browser\/ Device\u2019s trusted environment. Video is rendered via the video player, which can switch across different streams of different bitrates.<\/li>\n<\/ul>\n<\/li>\n<li>Dynamic watermarking to deter screen capture<\/li>\n<\/ul>\n<p>Widevine is still an emerging technology. As I mentioned earlier, although ubiquitously supported by Google\u2019s ecosystem (and Firefox), Widevine is not supported by Microsoft\u2019s Internet Explorer or by Apple. For content creators wishing to stream across all devices and software, they need a multi-DRM strategy. At VdoCipher we provide Widevine for Chrome, Fairplay for Apple devices. This multi-DRM strategy ensures that content providers can fully rely on VdoCipher for distributing content on all devices.<\/p>\n<h2 id=\"8\"><b>Widevine CDM for Delivering the Best User Experience<\/b><\/h2>\n<h4><strong>No plugins are necessary because of Native Widevine CDM<\/strong><\/h4>\n<p>VdoCipher\u2019s implementation of Widevine DRM makes sure that videos are played on Desktop devices using the native HTML5 video player. Inherently google devices &amp; browsers have Widevine CDM (Content Decryption Module), which allows for this hardware-based secure HTML5 playback.<\/p>\n<h4><strong>Highest Quality Adaptive Streaming with DASH<\/strong><\/h4>\n<ul>\n<li>VdoCipher\u2019s implementation of Widevine also makes use of the DASH streaming protocol. It is an open-source and widely adopted video streaming standard.\u00a0 DASH ensures that the same video file can be used across all devices (with the exception of iPhone). This considerably reduces the storage requirements on Server\/Content Delivery Network, as they only need to store one file container that would stream on most devices.<\/li>\n<li>The most valuable aspect of DASH protocol is adaptive playback,\u00a0 to stream the best quality for given network bandwidth. In the urban locations where users watch videos, the network connections can often fluctuate wildly. This can be because the viewer may be watching while traveling, or that more people are logging in to the shared network at the same time. VdoCipher video player monitors the user\u2019s network quality. Then it streams the best possible resolution for that given network quality.<\/li>\n<li>DASH is also used for streaming via HTTP, which is not blocked by firewalls, which is the case for streaming formats such as RTMP.<\/li>\n<\/ul>\n<h2 id=\"9\"><b>Encrypted Streaming + DRM License\u00a0<\/b><\/h2>\n<h4><strong>Video Encoding at multiple bitrates<\/strong><\/h4>\n<p>As mentioned in the previous section, video streaming in urban networks requires adaptive bitrate streaming. The video encoding process optimizes the video size to deliver the highest quality at the lowest bitrate. The most popular video codecs in use today are H.264 and VP9. SD resolution streams are encoded using H.264 codec, which has the widest decoder support. On the other hand, HD resolution streams are encoded using VP9. This is done for the delivery of 1080p streams to devices such as Android TV. As of February 2018, hardware-level decryption for Widevine-encrypted streams are available for Smart TVs by the following device makers: LG (WebOS), Panasonic (FirefoxOS), Philips (AndroidTV), Samsung (Tizen), Sharp Aquos (AndroidTV), Sony Bravia (AndroidTV. Different files of different bitrate and resolutions are broken down into fragmented MP4 segments of equal length.<\/p>\n<h4><strong>Videos files of different bitrates are each encrypted with CENC<\/strong><\/h4>\n<p>In Widevine DRM each individual video track is separately encrypted, using CENC (Common encryption Scheme). CENC ensures that each video segment is encrypted only once. The keys can be reused by different supporting DRMs (such as Playready). Fairplay has not yet made this API available, thus Fairplay streams have to be separately encoded currently.<\/p>\n<h4><strong>VdoCipher communicates with the Widevine license server to send the content decryption keys<\/strong><\/h4>\n<p>On packaging and encrypting the video, the VdoCipher packager requests for content decryption keys from the Widevine DRM license server. Widevine DRM license server subsequently returns this data to VdoCipher.<\/p>\n<p>The information regarding the encryption\/ decryption key is then inserted to the Media Presentation Description (MPD). This information can only be understood by the black-boxed Content Decryption module inside the browser\/ device.\u00a0 It uses the info to prepare a\u00a0 <a href=\"https:\/\/www.vdocipher.com\/page\/widevine-drm-license-server\">DRM license<\/a> request from the Widevine license server.<\/p>\n<h4><strong>Make Highly Specific DRM Licenses with VdoCipher<\/strong><\/h4>\n<p>Using VdoCipher\u2019s\u00a0 Widevine DRM architecture, you can create highly specific DRM licenses at the time of video upload. For instance, you can limit HD Streaming only to devices that support L1 video decryption (wherein decryption and decoding are both hardware-based). You can limit devices having L3 security (Widevine CDM is limited to browser) to only SD playback. Hollywood studios and DECE often require streaming services to follow this policy, giving higher priority of security for HD video content.<\/p>\n<p>Licenses also enable you to have a rental model in addition to a transaction video-on-demand model. Most Electronic Sell-Through platforms such as iTunes and Google Play Movies enable their users to either rent films for a period of time or purchase the license outright for unlimited viewings. Options to rent films tend to limit users to only view the film within a period of 48 hours from first starting playback. VdoCipher\u2019s implementation of a DRM license enables you to customize for how long a license is valid once it has been served for the first time.<br \/>\n<div style='text-align:left!important;'>\n  <a href='https:\/\/www.vdocipher.com\/dashboard\/register'>\n    <div class='btn cta' style='font-weight: 400;font-size: 16px;margin-top: 15px;background-color: #5f50e4; color: white!important;'>Get Started with Free 30-day Trial<\/div>\n    <\/a>\n<\/div>\n<p>&nbsp;<\/p>\n<p><iframe loading=\"lazy\" title=\"Widevine DRM Video Streaming with VdoCipher: Hollywood Approved\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/l0waqBMM4VE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Widevine DRM Glossary<\/strong><\/h2>\n<p>Here&#8217;s a glossary of terms related to Widevine DRM<\/p>\n<h3><b>Shaka HTML5 Video player<\/b><\/h3>\n<p>WIth Widevine DRM you get the Shaka video player, for any platform which supports htm5. <a href=\"https:\/\/www.vdocipher.com\/blog\/shaka-player\">Shaka player<\/a> ensures secure video playback online.
