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.

Media distribution with sample variants for normalized encryption

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.

System and method for media delivery using common mezzanine distribution format

A system and method for facilitating fast channel change in a streaming media network comprises receiving media content assets packaged in a common mezzanine distribution format (CMZF) container structure, wherein the media content asset is provided as CMZF-formatted media content in a CMZF stream scheme. Upon receipt, the CMZF-packaged media content assets are transformatted into corresponding CMZF segments stored in a local cache corresponding to a plurality of media channels. Responsive to a channel change request from a user equipment (UE) device, a unicast or multicast burst is sent comprising Reliable User Datagram Protocol (R-UDP) packets or Real-time Transport Protocol (RTP)-encapsulated partial or full virtual segments (R-SEG) generated from the CMZF segments corresponding to the requested channel.

System and method for facilitating fast channel change

A system and method for facilitating content delivery with end-to-end encryption in a network architecture using a common intermediary mezzanine distribution format (CMZF). An edge media router (EMR) device is provided in one embodiment that is configured to receive a media content asset packaged in a CMZF container structure, wherein the media content asset is provided as CMZF-formatted media content in a CMZF stream scheme. The CMZF container structure, configured to facilitate carriage of ISOBMFF track and track metadata data objects as well as sample variants in PES payload in additional elementary streams, is operative to carry each bitrate representation of the media content asset encrypted in one or more encryption schemes at a headend. Upon receipt, the EMR device is configured to repackage the media content asset to generate one or more output formats without reencrypting the media content asset for storage at a storage node and/or for downstream delivery.
