DRM，数字权力管理已成为生命。它均用于物理介质（包括CD，DVD，Blu-ray Discs）和数字分布的内容上。 DRM控制了如何使用内容，何时，何时，何时何地。但是，完美的DRM仍然难以捉摸，每种变化通常在其释放之后不久（或之前）释放后不久就会破解或绕开。 DRM的使用源于使用文件共享网络保护内容分布的需求，该网络的大小由于宽带互联网服务的扩散而增加。但是，要使文件共享有效，用户需要相对于共享内容的内存大小具有足够的上传带宽。借助压缩音频和视频内容，文件共享相对成功，但是对于需要内存足迹的内容比以前通常共享的大小要大得多，分发变得更加困难。随着高清内容的扩散，我们认为传统意义上的DRM似乎不再是必要的。具体而言，我们认为，由于宽带速度的极端不对称性和ISP的既得经济激励措施的极端不对称性，使用真实高清内容的自然文件大小本质上是其自身的DRM形式。
DRM, Digital Rights Management, has become pro- lific. It is used on both physical mediums (including CDs, DVDs, Blu-Ray discs) and digitally distributed content. DRM controls how, when, where and by whom content gets used. However, perfect DRM remains elusive with each variation often being cracked or circumvented by various hacking groups shortly after (or before) its release. The use of DRM grew out of the need to protect the distribution of content with file-sharing networks, which grew in size due to the proliferation of broadband internet services. However, for file-sharing to be effective, users need to have sufficient upload bandwidth relative to the memory size of the content being shared. With compressed audio and video content, file-sharing has been relatively successful, but for content that requires a memory footprint a magnitude larger than typically shared before, distribution becomes significantly harder. With the proliferation of high-definition content we argue that DRM in the traditional sense no longer appears necessary. Specifically, we posit that using the natural file size of true high- definition content essentially acts as its own form of DRM due to the extreme asymmetry of broadband speeds and vested economic incentives of ISPs with regards to enforcement.
