Abstract
A system and method that receives a tune request in a switched digital video (SDV) system, where the tune request includes an identifier of a set-top box, and an SDV channel. The method receives a content stream associated with the SDV channel. The method retrieves conditional access (CA) information from a local cache, where the CA information includes encryption information for the content stream. The method converts the content stream to an encrypted content stream using the encryption information, and sends the encrypted content stream to the set-top box.
