Abstract: A method and system provide the ability to process video content on a headend. A video processing server authenticates with a key server and public keys are exchanged. The key server generates and places a content key into a document that is signed with the public key. A client on the video processing server receives the document, extracts the content key, and saves the content key to a database. The video content is encrypted using the content key and DRM signaling elements are added to a manifest. The encrypted video content and manifest are received in the head end, a key ID is extracted from the manifest and provided to the CPIX client to retrieve the content key from the CPIX document. The encrypted video content is decrypted using the content key resulting in clear content that is provided to a downstream packager that encrypts and repackages the content for transmission to recipients.

Abstract: Broadly, this disclosure discloses various computing technologies that include a processor in communication with an imaging device and with an illumination device. The processor receives a set of imaging data from the imaging device such that the processor is able to identify an object within the set of imaging data and determine a set of coordinates. The processor then sends the set of coordinates to the illumination device such that the illumination device can output an illumination based on the set of coordinates.

Abstract: Provided is a content delivery method and architecture for delivering content from a node in a content delivery network (CDN) using an anycast address to direct a requesting device to access a content manifest. The manifest server of the CDN may select the provided manifest based on information received from the requesting device and/or any other network information, may alter attributes of the manifest itself, or direct the requesting device to a different device or manifest server of the CDN to obtain the manifest. The selection of the manifest, alteration of the manifest, or new location to obtain the manifest causes the connection for content to occur at one or more servers accessible through a unicast address, rather than an anycast address.

Abstract: A method for distributing video content from a server to a plurality of media devices is provided allowing adaptive bit rate encoding to better utilize bandwidth. The method includes: determining, by the server, the bandwidth to allocate to each of the plurality of media devices using a hypertext transfer protocol-based live streaming client model or a need parameter vector, refining this determination by utilizing client feedback regarding client buffer level and playback state, client hardware capabilities, and client internally measured download rate, and providing the allocated bandwidth to each of the plurality of media devices; wherein the video content is transmitted in a plurality of segments from the server, and wherein each segment is transmitted at a bitrate that may vary from segment to segment.

Abstract: A network apparatus and a content distribution apparatus are described. The network apparatus is configured to transcode and transmit pre-broadcast content into transcoded content according to a format associated with a content distribution apparatus. The transcoded content includes a distribution indicator to restrict distribution of the transcoded content to one or more remote apparatus. Network apparatus is configured to transmit a "delta file" to content distribution apparatus with transcoded content and instructions to signal modifying the pre-broadcast content. Content distribution apparatus is configured to receive transcoded pre-broadcast content and "delta file" with instructions from network apparatus. Content distribution apparatus removes the distribution indicator from the transcoded pre-broadcast content once the signaling instructions indicates that the broadcast content corresponds with pre-broadcast content. Content distribution apparatus may use the "delta file" to modify the transcoded pre- broadcast content such that the modified pre-broadcast content corresponds with broadcast content with a tolerance.
