A system and method for distributing watermarked media content assets in which a main track of a media content asset includes a first watermarking payload and at least one variant track includes a second watermarking payload. A plurality of composite segments of the media content asset are generated for distribution, wherein each composite segment includes a portion of the main track and may include a corresponding portion of at least one variant track. The composite segments may be uploaded to a delivery node operative to deliver segments responsive to a unique watermarking signature provided by a client controller operating in conjunction with a watermarking session manager.

The present invention provides methods, apparatuses, and systems for delivering protected streaming content to a receiving device. In an aspect of the present invention, a broadcaster provides streaming content. To ensure viewers are properly authorized, the streaming content is encrypted with a traffic key. The traffic key is provided to the users via a key stream message, which is encrypted with a service key. The user obtains at least one rights object from a rights issuers and the at least one rights object includes the service key so that the streaming content may be used. The at least one rights object also contains information regarding usage rights that may be configured by the rights issuer so that, depending on the user and/or the receiving device, different rights may be available. The key stream message may include a program category variable value that indicates the type of content and in conjunction with the rights object, determines what usage rights exist for the streaming content.

Techniques and mechanisms described herein facilitate the efficient common storage of partially encrypted content. According to various embodiments, a client device to transmit a designated representation of a media content item via a communications interface may be received. The media content item may be associated with a plurality of representations including the designated representation. The media content item may be associated with first media content data and second media content data. The first media content data may be shared among the plurality of representations. The second media content data may be specific to the designated representation. The first media content data may be combined with the second media content data to create a designated partially encrypted media content portion associated with the designated representation via a processor. The designated partially encrypted media content portion may be transmitted to the client device via the communications interface.

The present invention relates to systems and methods suitable for real-time streaming over a decentralized or centralized network. In the decentralized network, the present invention relates to a system and method that utilizes a block-chain distributed network to securely and reliably stream multimedia in real-time. In the centralized network, the present invention utilizes a centralized stream manager to manage nodes within the distributed network to securely and reliably stream multimedia in real-time.

During the boot process, a secure wireless display connect module of the BIOS can authenticate a wireless display and determine whether the wireless display can comply with the HDCP. When the secure wireless display connect module determines that the wireless display is HDCP compliant, the secure wireless display connect module can create an ACPI secure blob in which is stored a shared session key generated as part of determining that the wireless display is HDCP compliant. A video authentication session module of the BIOS can then retrieve this shared session key from the ACPI secure blob and use it to encrypt video frames that are to be sent to the wireless display. The video authentication session module may additionally embed a session ID and a timeout into each video frame which the wireless display can employ to detect when the video frame should no longer be displayed.

In one aspect, an example methodology implementing the disclosed techniques includes, by a computing device, splitting a content being displayed on a screen over time into a first plurality of frames and displaying on the screen the first plurality of frames in accordance with a frame rate. Each frame of the first plurality of frames can include a portion of the content such that a composite of the first plurality of frames shows the content. In some cases, the splitting of the content may include applying time decomposition to the content.

The disclosure relates to content delivery systems such as gateways for use in locations where the services of many end user devices are provided by a common management entity, such as hospitality, dormitory, healthcare, or other enterprise settings. The disclosure includes methods of initializing a gateway configuration and operating a gateway by ingesting content from a variety of signals (satellite, broadcast, cable, and IP), processing the content to have additional desired features, and reassembling content in various forms for delivery to individual end user devices.
