A method for processing a media stream is proposed, which includes, at a media distribution unit including a processor: obtaining, based on media stream data received from a media encoder, at least one media data chunk of the media stream, wherein the at least one media data chunk is a separately addressable data unit by a request for media data received by the media distribution unit; generating, based on received media stream data, metadata related to the media data chunk; storing the media data chunk in a memory of the media distribution unit, wherein the memory is used to store media data chunks as separately addressable data units for a memory read from the memory; and updating a list of media data chunks stored in the memory, based on the metadata related to the media data chunk.

A method for processing a media stream is proposed, which includes, at a media distribution unit including a processor and first and second memories for storing media data. The first memory stores media data chunks of the media stream which are separately addressable media data objects for memory read in the first memory. The second memory store media data fragments of the media stream which are separately addressable media data objects for memory read in the second memory, the fragments respectively including one or mode media data chunks: receiving a request related to media data, determining, based on the received request, a descriptor of data to be generated to serve the request, based on the descriptor, retrieving first data from the first memory, and second data from the second memory, and generating data to be generated to serve the request based on the first data and the second data.

A server in a content delivery network (CDN) receives a request for a web page of a domain handled by an origin server. The server retrieves the web page and the web page references a video. The server retrieves a file that indicates a list of locations of the domain in which segments of the video are located. The server fetches at least an initial portion of the segments. The server receives a request for the video. The server transmits to the requester at least the initial portion of the segments. The server receives a subsequent request of a different portion of the segments. The server transmits a response to the requester that instructs the requester to transmit the request for the different portion of segments to a second server in the CDN.

The described technology is generally directed towards validating content selection graphs for use in an in-memory content selection graph data store. When a content selection graph data is generated, the graph nodes can correspond to prebuilt response data. The response data for any of the nodes can be verified against rules based on the type of a node, for example, as well as based on client-specific information for types of clients. The overall validation process can validate the content selection graph for subsequent use, can result in errors or warnings being logged (which may or may not render the graph unusable, e.g., depending on severity), or can fail the content selection graph. If validated, the content selection graph can be used to rapidly return response data when content from the graph is requested.

The described technology is generally directed towards coordinating the generation, validation and enabling of content selection graphs in an in-memory content selection graph data store. When a set of content selection graphs is requested, a coordinator starts the generation of the relevant graphs. Upon successful generation, the coordinator starts a validation of the generated graphs against rules for the nodes/response data in the graphs. If the generated graphs pass validation, the coordinator enables the graph set for use in an in-memory cache, whereby when a request to return content selection data is received, an active graph that corresponds to the request and the current time is accessed to obtain and return the response data as the requested content selection data.

The present invention is directed to a method and apparatus for archiving media content, and more particularly to archiving television and radio broadcasts for later delivery, on-demand, via the Internet. A capture server is used to receive and gather a plurality of media sources for archiving and subsequent delivery to client users. The capture server is capable of receiving numerous digital or analog media signals from a variety of media sources, including transmission through traditional broadcast, coaxial cable, the Internet, personal and public camera systems and the like, and converting these media signals into addressable blocks of media content. Furthermore, the capture server is capable of encoding received media signals, particularly analog media signals, applying an application programming interface and preparing the media signals for implementation by the system in an identifiable form or architecture.

A dynamic data extraction, distillation, and enhancement system is disclosed that includes a dynamic extraction, distillation, and enhancement framework. The framework includes an allocator, extractor, and deconstructor stored in a non-transitory memory that, when executed by a processor, receive files in different formats from data sources, determine a native format of each file, identify and extract an embedded object from a file, deconstruct the file into components, assign each file to one of a plurality of streams based on the native format of the file, assign the embedded object to a stream based on a format of the embedded object, and assign a deconstructed component to a stream based on a format of the deconstructed component. The native format includes one of text, video, image, or audio. Each stream corresponds to one native format. The streams include a text stream, an audio stream, a video stream, and an image stream.

A system for maximizing storage of encrypted content in a storage system includes one or more processors; and a storage medium storing instructions. When executed, the instructions may configure the one or more processors to: receive, from a first client device, a first data structure encrypted commutatively with a first key and a common key, the receiving system lacking access to the common key; receive the first key and a first segment identifier; receive, from a second client device, a second data structure encrypted commutatively with a second key and the common key; receive a second segment identifier; using the first key, partially decrypt the first data structure; storing the partially decrypted first data structure; and selectively storing a copy of the second data structure based on whether content of the first data structure corresponds to content of the second data structure.

Interaction output over a local computer-readable medium (CRM) generated based on user interaction with rendered content input representing a virtualized asset being is received at a virtualized asset local provisioning server. A manner to exploit the virtualized asset is determined from interaction output. The virtualized asset is exploited based on the determined manner to exploit the virtualized asset. A request for a portion of the virtualized asset generated in response to the exploiting the virtualized asset is intercepted. If it is determined that the portion of the virtualized asset is absent from the local storage, a request for the portion of the virtualized asset is sent to a virtualized asset delivery system over a non-local CRM; the portion of the virtualized asset retrieved by the virtualized asset delivery system is received over the non-local CRM; and the received portion of the virtualized asset is used in exploiting the virtualized asset.
