Abstract
Techniques are described by which decryption key rotation may be accomplished to support the protection of live streaming content. During playback of content using a decryption key, the client begins acquisition of a second stream of the same content (including a new decryption key) such that the client can transition playback of the content from the first stream to the second with few or no visible artifacts from the viewer's perspective.
