摘要：Systems and techniques can include one or more computer-implementedmethods that include: digitally signing Universal Resource Locator (URLs), which havebeen isolated from a source playlist document, to generate digitally signed URLs;generating a protected playlist document from the digitally signed URLs; and providing
the protected playlist document for use in a video on demand system. The digitallysigned URLs can be in a protected master playlist document and can point to two ormore sub-playlist documents, which can themselves be protected. The digitally signedURLs can be in a protected sub-playlist document and can point to encrypted videofragments. In addition, a URL of the protected master playlist document can itself bedigitally signed, and the digitally signed master playlist URL can be sent to a mobiledevice in response to a request for video from the mobile device.
