Abstract: A system and method for distributing content in a network architecture using a common intermediary mezzanine distribution format (CMZF). A media content asset may be processed for packaging in a CMZF container structure configured to carry each bitrate representation of the media content in a valid CMZF stream scheme, the media content encrypted in one or more encryption schemes. The CMZF formatted media content may be provided to an origin server for file-based distribution over a network which is of one of the following types; unmanaged network, managed network, or a combination thereof, and/or to a streaming network node for stream-based distribution over a over a network which is of one of the following types; unmanaged network, managed network, or a combination thereof. In one embodiment, the CMZF container structure may be based on an MPEG-TS format extended to facilitate carriage of ISOBMFF track and track metadata data objects in PES payload in additional elementary streams. In another embodiment the CMZF container structure may be based on an MPEG-TS format to facilitate carriage of sample variants in PES payload.

Abstract: A media distribution system and method with sample variants for normalized encryption involves encrypting a main track of a media content asset using a first encryption scheme and encrypting a sample variant track of the media content asset using a second encryption scheme, and performing at least one of: storing the encrypted main track and encrypted sample variant track of the media content asset packaged in a storage format, and transmitting the encrypted main track and the encrypted sample variant track 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.
