万岁(一个不同的)DRM!
在3月份的SportsPro OTT USA活动上, 在皇后区的花旗球场举行, 纽约, 有人说, “数字版权管理已死”，然后扔掉麦克风. And al虽然 my gut reaction was to immediately dismiss that statement, 我花了些时间来思考, 我认为这值得更多的考虑.
数字版权管理一直是流媒体视频提供商的主要内容. 使用证书和加密, 他们可以利用DRM服务作为内容保护层, ensuring that only people who have the right to view content (such as those who have paid for it) can do so. 但DRM在消费者中也很有争议, 因为它限制了他们可以观看或存储数字资产的地方. 许多人认为，一旦他们购买了数字资产, they should have the right to put it anywhere they want and watch it wherever they want, 就像DVD一样.
作为一个概念，DRM是完全有效的. Content owners should be able to protect their content so that consumers don't illegally share it. But consumers should be able to store that content wherever they want once they have purchased it. 是的, they only have rights to watch it (and not to copy or distribute it), but DRM shouldn't be so constricting that other consumer rights—like wanting to watch it on another device, 来自不同的媒体服务器, or in a different country than the one in which they purchased it—are restrained as well.
Managing the digital rights to a piece of content shouldn't go away. 也许, 虽然, the mechanism by which those rights are assured and protected should change, and maybe that's what the mic drop at SportsPro OTT USA was about.
处理身份的新技术, 身份验证, 和所有权, 比如区块链和nft, hold a lot of promise to transform the way content owners protect and manage the digital rights to their assets. In a ledger-based approach, for example, it wouldn't matter where the user was watching the asset. So long as the playback feature of the asset is connected to the ledger, the consumer's right to watch the content can be au然后ticated.
Imagine a user's crypto wallet containing all of the content they have purchased (such as the way NFTs are stored). 当用户想要玩一段内容时, 这名球员, connected to the wallet via an API or some other programmatic means, 只是检查钱包的权利. 媒体接口, 然后, would be a thumbnail representation of content within the wallet, making it easy for users to find content from their collection that they want to watch.
This approach could even address subscriptions and episodic content as well (al虽然 in a slightly different fashion, because the consumer hasn't purchased any of the digital assets), as 这名球员 has a thumbnail representation of all available content within the other OTT provider. So, imagine the user opening a Netflix app that is already au然后ticated against their crypto wallet. 当用户点击一段内容观看时, Netflix ascertains their active subscription as an entry in the global ledger and allows the content to play.
The interesting thing about this approach is that encryption is no longer needed. No more exchanged certificates via 这名球员 and a certificate server in the DRM chain. As an immutable entity, the ledger is the source of truth for purchase (i.e.(1)所有权.e.、订阅). This means the consumer can watch whatever they own wherever they want and "store" it however they see fit.
DRM作为一个概念不会消失，也永远不会消失. 但它确实需要转型. 现有的方法对消费者来说限制太大. But a ledger- and wallet-based approach not only frees the consumer to handle their media the way they want, it also assures the continuity of digital rights for the content owner.
(不同的)DRM万岁.
