Abstract: A system (1000, 1100) and method (200D) for distributing watermarked media content assets wherein a main track of a media content asset is provided with a first watermarking payload and at least one variant track is provided with a second watermarking payload, the watermarking payloads identified by respective identifiers. A plurality of composite segments of the media content asset are generated (260) in a suitable distribution container format, wherein each composite segment includes a segment portion of the main track and a corresponding portion of the at least one variant track, which may comprise a plurality of sample variant (SV) tracks. The main track and the at least one variant track may also be encrypted using respective encryption schemes identified via suitable KID parametric information independent of the watermarking payload identifiers. The composite segments may be uploaded to a network node (316) associated with a content delivery network (CDN) (336) that facilitates delivery of the watermarked segments to a client device (340, 1200) based on a unique watermarking signature provided via a customized manifest from a client controller (320) operating in conjunction with a watermarking session manager (318).

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 Multicast Adaptive Bitrate Bandwidth Control Agent, MABR BCA, (16, 83) configured to manage bandwidth of a plurality of MABR data streams in an Internet Protocol Television, IPTV, over Data Over Cable Service Interface Specification, DOCSIS, system, wherein a bandwidth bottleneck exists on either an inbound, IP-network side of a Cable Modem Termination System, CMTS, (18) or on an outbound, DOCSIS/RF-network side of the CMTS. The MABR BCA configures multiple virtual pipes (17-1 through 17-n) on the inbound, IP-network side of the CMTS (18) when the bottleneck is on the outbound, DOCSIS/RF-network side of the CMTS. One virtual pipe is configured for each service group to manage the bandwidth per service group for output RF ports on the CMTS. When the bottleneck is on the inbound, IP- network side of the CMTS (18), the MABR BCA configures one virtual pipe (17- 2) on the inbound, IP-network side to manage the bandwidth for input Ethernet ports on the CMTS.
