Media distribution with sample variants for normalized encryption

An apparatus, comprising:

• one or more processors;
• a plurality of network interfaces configured to receive media content assets from one or more content sources;
• an encoder for generating a plurality of bitrate representations for each media content asset;
• and
• one or more persistent memory modules having program instructions stored thereon which, when executed by the one or more processors, perform the following:
• processing a media content asset for distribution with end-to-end encryption, the processing comprising:
• (i) encrypting a main track of the media content asset using a first encryption scheme, the main track comprising a plurality of samples and each sample of the main track encrypted using the first encryption scheme, and (ii) encrypting a sample variant track of the media content asset using a second encryption scheme, the sample variant track comprising a plurality of variants respectively corresponding to the plurality of samples of the main track and each of the variants of the sample variant track encrypted using the second encryption scheme, wherein the second encryption scheme is different from the first encryption scheme used for encrypting the main track of the media content asset;
• and
• transmitting the encrypted main track containing the plurality of samples and the encrypted sample variant track containing the corresponding plurality of variants in a distribution container format to an edge media router (EMR) device configured to repackage the media content asset into a delivery container format without reencrypting the media content asset, the delivery container format comprising a format compatible for processing by at least one of a premises gateway node, a set-top-box (STB), and a user equipment (UE) device.

A non-transitory machine-readable storage medium having program instructions thereon that are configured to perform following acts when executed by one or more processors of a media packaging system:

• processing a media content asset for distribution with end-to-end encryption, the processing comprising:
• (i) encrypting a main track of the media content asset using a first encryption scheme, the main track comprising a plurality of samples and each sample of the main track encrypted using the first encryption scheme, and (ii) encrypting a sample variant track of the media content asset using a second encryption scheme, the sample variant track comprising a plurality of variants respectively corresponding to the plurality of samples of the main track and each of the variants of the sample variant track encrypted using the second encryption scheme, wherein the second encryption scheme is different from the first encryption scheme used for encrypting the main track of the media content asset;
• and
• transmitting the encrypted main track containing the plurality of samples and the encrypted sample variant track containing the corresponding plurality of variants in a distribution container format to an edge media router (EMR) device configured to repackage the media content asset into a delivery container format without reencrypting the media content asset, the delivery container format comprising a format compatible for processing by at least one of a premises gateway node, a set-top-box (STB), and a user equipment (UE) device.
