Multi-DRM vs one protected player: cost and coverage
Multi-DRM reaches the most devices, including TVs, and studio licences usually require it, but costs fees, approvals and testing. A protected player covers your own apps with one set of rules.

Multi-DRM, using Widevine, FairPlay and PlayReady together, reaches the most devices, including browsers and smart TVs, and film and series licences usually demand it. It costs licence fees, approvals, a large test matrix and a second set of protections for the leaks DRM can't see. One protected player inside your own apps covers fewer kinds of screen, but applies one set of rules everywhere it runs, offline and on desktop. The right choice depends on whose content it is, where your viewers watch and where your leaks really happen.
Tools that claim to get past DRM are sold openly, and they have reached phones too. From late 2022 until a September 2024 update, StreamFab's Android app offered downloads from Netflix and Amazon Prime Video. Its "DRM MPD Downloader" for Windows and Mac says it saves DRM-protected streams from any site as MP4 or MKV files "without requiring technical configuration", and its home page lists downloaders for Netflix, Prime Video, Disney+, JioHotstar and online-course marketplaces. KeepStreams advertises downloads from "3,000+ sites", up to 4K.
Two ways to protect a video library
Multi-DRM encrypts each video once and lets the DRM system built into each device decrypt it. That means Widevine on Android and in Chrome, FairPlay on Apple devices, and PlayReady in Edge and on many TVs. A licence server decides who receives keys. Our multi-DRM explainer covers how Common Encryption lets one library work across all three.
One protected player means your platform's own apps play the video, using the platform's encryption and rules rather than the operating system's DRM module. Coverage is wherever your apps run, and the protection is only as good as the team that builds and maintains the player.
Both approaches protect delivery. Neither, on its own, stops a second phone filming the screen or one login serving a group. So the comparisons below include the layers you need either way.
Device coverage compared
| Where viewers watch | Multi-DRM | One protected player |
|---|---|---|
| Android phones and tablets | Widevine: hardware-backed on many phones, software-only on some budget and modified ones | Wherever your Android app installs |
| iPhone and iPad | FairPlay, once Apple approves your organisation | Wherever your iOS app installs |
| Desktop browsers | Widevine in Chrome and Firefox, mostly software-only; FairPlay in Safari; PlayReady or Widevine in Edge | The weakest point: a player written in web code has far less protection than an app |
| Windows and Mac apps | Possible, but needs its own DRM integration and agreements | Wherever your desktop app installs |
| Smart TVs and streaming sticks | Widely supported, which is DRM's biggest advantage | Needs a separate app for each TV platform, so many institutes skip TVs |
| Offline downloads | Supported in native mobile apps under licence rules; limited in browsers | In every app you ship, under rules your platform sets |
For an OTT service, smart TVs are often where most viewing happens, and DRM is the practical way to reach them. For a coaching institute, students mostly watch on phones and laptops, so desktop coverage matters far more than TVs. That's why secure playback on Windows and Mac is usually a bigger decision for an institute than DRM on a television.
What each approach really costs
Prices vary by vendor and volume, so compare the cost lines rather than headline quotes.
| Cost line | Multi-DRM | One protected player |
|---|---|---|
| Licences | A hosted licence service usually charges by volume, such as licences issued or active viewers, so cost grows with plays | No per-licence fees to a DRM provider; the platform's own fee covers the player |
| Approvals and agreements | Apple's approval for FairPlay credentials, a Widevine agreement with Google, Microsoft's terms for PlayReady | None from device makers; your contract is with the platform |
| Packaging and storage | Older devices can force a second encrypted copy of the library | One copy in the platform's format |
| Apps and players | DRM integration in every app, browser player and TV app | One player per platform, built and updated by the vendor |
| Testing | Every device, browser, OS version and security level your viewers use | Every app version on the devices your students use |
| The layers DRM doesn't cover | Watermarking, recording detection, account controls and PDF protection, bought or built separately | Often in the same player, but check each one |
| Leaving | Standard formats make it easier to switch licence providers | Content may need re-encoding from the originals, so keep your originals |
The line most budgets miss is the second-last one. Multi-DRM is a delivery lock, so a service that buys it still needs separate answers for camera recording, shared logins and leaked notes. Our guide to why DRM alone can't stop piracy sets out those routes.
Offline viewing
Downloads matter in India, where students study on patchy 4G, in hostels and on long train journeys. With multi-DRM, offline viewing is well supported in native mobile apps. The licence can allow the video to be stored and set an expiry, and the app renews it when the phone reconnects. Offline DRM playback in desktop browsers is limited, so services that offer downloads usually do it only in apps.
A protected player handles offline viewing in whichever apps it runs in, including desktop apps. The platform sets the rules: how long downloads last, how many devices can hold them and what happens when a batch ends.
Either way, ask the same three questions. Where do downloads live, when do they stop working, and does offline playback still show the viewer's identity on screen? Our explainer on how secure downloads work covers the weak points.
Leak protection: what each one stops
| Leak route | Multi-DRM | One protected player |
|---|---|---|
| Downloading or ripping the stream | Stopped where every path uses DRM | Stopped where every path uses the player |
| Recovering keys on software-only devices | The main known weakness; Widevine's software level was publicly broken in 2019 | Depends entirely on the vendor's engineering, so ask for evidence |
| Screen recording on phones | Often comes out black with hardware-backed DRM | Depends on what the app blocks or detects on each platform |
| Screen recording on desktops | Often works in browsers with software-only DRM | Depends on the desktop app; browsers are weak for both |
| A second phone filming the screen | Not stopped | Not stopped; only a watermark helps trace it |
| A shared or sold login | Not stopped: every sharer gets a valid licence | Only if account-sharing controls are part of the platform |
| Rooted phones, emulators and modified apps | Some devices fall back to software-only protection | Depends on device-integrity checks in the app |
| PDFs and notes | Not covered | Only if the platform protects documents too |
The honest reading of this table is that neither approach closes the camera route, and both depend on what is built around them. DRM's hardware-backed levels have years of industry use behind them; a protected player's strength can't be assumed and has to be demonstrated. Our comparison of Widevine L1 and L3 explains why each device's security level matters so much. Getting round either kind of protection to copy paid video can be an offence under section 65A of the Copyright Act, 1957.
When DRM isn't optional
- You license films or series from studios. Content licences usually specify the DRM, security levels and output protection required for each resolution.
- Most of your viewing is on TVs. Smart TVs and streaming sticks support DRM natively, and building a protected app for every TV platform is rarely practical.
- A business customer asks for it. Some enterprise and partner contracts name DRM explicitly.
A coaching institute owns its lectures, so no studio sets these terms. It can choose on the merits: where students watch, how its leaks actually happen and what each approach costs at its scale.
A decision guide
| Your situation | Usually the better fit | What to add either way |
|---|---|---|
| OTT service with licensed studio content | Multi-DRM, as the licences require | Watermarking, and stream and device limits |
| OTT service with its own originals, watched mainly on TVs | Multi-DRM for TVs and browsers | Account-sharing controls and watermarking |
| Coaching institute whose students watch on phones and laptops | One protected player in branded apps, with desktop apps for laptops | Visible and invisible watermarks, recording detection, account controls, PDF protection |
| EdTech product with a large web audience | A mix: DRM in browsers, a protected player in apps | Watermarking, and one set of account rules across both |
A mixed setup is common and sensible, but it doubles what has to be kept consistent. If the browser path is weaker than the apps, that is where leaks will come from.
Questions to ask before you choose
- Which of our viewers' devices get hardware-backed protection, and what quality do the others get?
- What will we pay as plays, viewers and downloads grow, and is any part priced per licence?
- Who holds the FairPlay credentials and DRM agreements, and what happens to them if we leave?
- Is any path, such as an old app version, a free preview or a desktop browser, weaker than the rest?
- Can you show a screen recording and a phone recording of our lecture, played on each platform?
- If a lecture leaks, can the copy be traced to the account it came from?
- Can we take our original files and data with us if we leave?
Upclass gives institutes branded apps in their own name on Android, iOS, Windows and Mac. VidSafe protects the lectures in them with VidSafe proprietary encryption, screen- and camera-recording detection, account-sharing prevention, PDF watermarking and RASP. VidSafe adds visible and invisible watermarks that are extremely hard to remove, even after heavy re-encoding, so a leaked copy can be traced back to the account it came from. Weigh it against a multi-DRM quote with our guide to whether DRM is enough to prevent piracy.
Frequently asked questions
Is multi-DRM expensive?
The main costs are a licence service that usually charges by volume, and approvals and agreements for each DRM system. Older devices can add packaging and storage, and every device your viewers use needs testing. On top of that you still need watermarking, account controls and recording detection, which DRM doesn't provide. Compare the total at your expected volume, not the licence fee alone.
Do I need DRM for an online course?
Not necessarily. Nobody requires DRM for lectures you own, unlike licensed studio films. What a course needs is protection against the routes lectures actually leak through: downloads, screen and camera recording, shared logins and PDFs. DRM covers only part of that, so judge any setup, with DRM or without, by how it handles each route.
Can one DRM system work on all devices?
No. Each platform supports its own DRM. Widevine runs on Android and in most browsers, FairPlay on Apple devices, and PlayReady in Edge on Windows, on Xbox and on many smart TVs. No DRM system can read another's licences, which is why services that want broad coverage use all three together as multi-DRM.
Does DRM work offline?
Yes, in native apps. Widevine and FairPlay both support licences that let a download play offline for a set period, after which the app must reconnect to renew it. Offline DRM playback in desktop browsers is limited, so most services offer downloads only in their apps.
