Method and system for secure over-the-top live video delivery

A computerized device operable as a client for handling secure distribution of content, comprising:

• memory operative to store computer program instructions;
• one or more processors;
• input/output interface circuitry;
• and
• interconnect circuitry coupling the memory, processors and input/output interface circuitry together,
• wherein the processors are operative to execute the computer program instructions from the memory to cause the computerized device to:
• initiate a media playback request and receive a playback request response;
• parse content information from the playback request response, the content information including content encryption keys, content encryption key identifiers, and content encryption key expiration times;
• retrieve content and manifest files from a content delivery server;
• detect content encryption key rotation boundaries between periods of use of different content encryption keys in decrypting retrieved content;
• issue requests to a license server ahead of a key rotation boundary to retrieve a second content encryption key to be used after a content encryption key rotation boundary is reached;
• and
• apply the second key for content decryption after the key rotation boundary is reached.
