Abstract:
Techniques are described for reducing time to decrypt a next encrypted frame in a content stream by optimizing a license/key acquisition process. When requesting content, a key identifier and/or license identifier may be included within a webpage using a link, script, or similar access point. When a client device sends a request for content, the loading of the webpage within the client device includes the embedded key identifier. Access to the key/license identifier at the client device then may initiate a key/license acquisition process by the client device. The key/license may be obtained from a key management device in parallel with, or prior to, downloading of at least a portion of the content stream.
