Abstract: Apparatus and methods for content fragmentation, distribution, protection, and re-constitution within a content distribution network. In one embodiment, the apparatus and methods enable distribution of content fragments to edge nodes (which may include user or subscriber CPE), thereby enabling edge networks or membership groups to be established wherein content can be shared solely at the edge. In one variant, high data bandwidth, symmetric uplink/downlink, low latency PHY links (e.g., 5G NR-compliant wireless interfaces) between the edge nodes participating in the edge networks or membership groups are used such that particular quality of service/experience performance requirements can be met. Distribution of the fragments also advantageously enhances redundancy and security.

Abstract: A method for whole-process trace leaving of video manuscript gathering, editing, and check, including: extracting a key frame from video clipping information, generating histogram data by using the key frame, and obtaining video modification information based on the histogram data; and on-chaining, by using timestamps as blockchain nodes, the video modification information completed at different time points to form a trace chain arranged according to the timestamp, to implement whole-process trace leaving for video clipping. The technical solutions of the present invention resolve a difficulty in whole-process trace leaving for video manuscript editing and issuing, and in addition, by using the blockchain techniques, implement tamper-proofing and security of trace information, thereby effectively improving security of gathering and editing in the media industry.

Abstract: A method is provided for managing over-the-top delivery of content through a plurality of content delivery networks (CDN). The method provided works transparently with standard HTTP servers supporting an initial request for content from a client to a first preferred CDN. If the first CDN does not have the content, the method includes provisions for the first CDN to acquire the content from a second CDN, or for the client to request the content from a second CDN directly. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.

Abstract: A method includes obtaining input encoded data slices from memory of the storage network, where the input encoded data slices include a set of encoded data slices interspersed with a set of auxiliary data slices, where a data segment was error encoded into the set of encoded data slices, and where auxiliary data was error encoded into the set of auxiliary data slices. The method further includes obtaining de-selection information associated with the input encoded data slices and de-selecting the sequence of input encoded data slices based on the de-selection information to produce deselected encoded data slices. The method further includes error decoding at least a decode threshold number of encoded data slices of the deselected encoded data slices in accordance with error decoding parameters to reproduce the data segment. The method further includes outputting the data segment to a requesting computing device of the storage network.

Abstract: A cable distribution system that includes a head end connected to a plurality of customer devices through a transmission network that includes a remote fiber node that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes a processor. A packetized elementary stream of a video is provided from the head end to customer devices through the transmission network, wherein the packetized elementary stream includes a plurality of groups comprising pairs of packetized elementary stream headers and packetized elementary stream payloads. A first one of the plurality of groups corresponding to a non-predicted coded picture of the video of the packetized elementary stream is determined. The first one of the plurality of groups is encrypted while not encrypting all of the plurality of groups of the video. A signal is provided from a conditional access system to a selected one of the plurality of customers that is suitable to be used to decrypt the first one of the plurality of groups.

Abstract: A processing service of a provider network may protect media content from being tampered with when it is transmitted from the provider network/transcoder to untrusted networks (e.g., third-party networks/CDNs) and to a media player. The processing service (e.g., the transcoder) generates a public and a private key. The service uses the private key to digitally sign content portions (e.g., video frames) before distribution to untrusted CDNs. The provider network creates a manifest that includes the public key. To play the media content, the media player obtains a manifest that includes the public key (via a secure/trusted connection with the provider network). The media player may then obtain the media content from an untrusted edge server/CDN and validate it using the public key that was separately obtained from the manifest (to verify the content was not tampered with).
