In one embodiment, the selection rules include leaving selected portions of the content stream unencrypted, including packets that include a PES header; or video packets that include various trick play data such as picture start, GOP start, sequence start, sequence end data; PIDs associated with a PAT, PMT, or the like; while other portions of the content stream may be encrypted, including video and/or audio PIDs, or other video and/or audio portions. In still another embodiment, Entitlement Control Messages (ECMs) may be inserted that employ an encryption/decryption key rotation scheme, such as odd and/or even scrambling control bit structures, which may also be rotated based on a variety of conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Selective and persistent application level encryption for video provided to a client","description":"A system, apparatus, and method are directed towards allowing ingestion of encrypted content into such as a VOD server, or PVR, or the like by selectively encrypting portions of a content stream based","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526612","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
