Abstract
Systems, methods, and computer readable media for providing video encryption. A device may receive an unencrypted content stream. The device may identify an encryption key and an entitlement control message (ECM) from an encryption package. The device may encrypt the unencrypted content stream using the encryption key to obtain encrypted data. The device may generate an encryption stream that comprises the ECM and the encrypted data.
Claims20
A device comprising:
- at least one computer processor;
- and
- at least one storage medium storing computer-executable code comprising:
- receive an unencrypted content stream;
- identify an encryption key and an entitlement control message (ECM) associated with an encryption package;
- encrypt the unencrypted content stream using the encryption key to obtain encrypted data;
- and
- generate an encryption stream that comprises the ECM and the encrypted data.
5 more elements
A device, comprising:
- at least one computer processor;
- and
- at least one storage medium storing computer-executable code comprising:
- determine that a criterion to request a plurality of encryption packages has been met;
- send a request for the encryption packages based on the determining;
- store the encryption packages in the at least one storage medium;
- based on an indication of unencrypted content, identify an encryption key and an entitlement control message (ECM) from a first encryption package of the plurality of encryption packages;
- encrypt the unencrypted content using the first encryption key to obtain encrypted data;
- and
- generate an encryption stream that comprises the ECM and the encrypted data.
7 more elements
A method comprising:
- receiving, by one or more processors, an unencrypted content stream;
- identifying, by the one or more processors, an encryption key and an entitlement control message (ECM) from an encryption package;
- encrypting, by the one or more processors, the unencrypted content stream using the encryption key to obtain encrypted data;
- and
- generating, by the one or more processors, an encryption stream that comprises the ECM and the encrypted data.
