Abstract: In one embodiment, a system component in a content delivery network (CDN), the CDN including a request router and edge caches, the request router being operable to determine which edge cache should serve content to a client, the system component including a processor, and a memory to store data used by the processor, wherein the processor is operative to receive a request for content from the client, and based on a decision to shut down a first edge cache after the client has already downloaded some of the content from the first edge cache, participate in a process to transfer the client from downloading the content from the first edge cache to downloading the content from a second edge cache in the middle of the client downloading the content so that the client continues downloading the content from the second edge cache. Related apparatus and methods are also described.

Abstract: A system can include a controller that employs an application interface to create and manage resources for encoding or transcoding an input media asset. The resources can include a media splitter to divide the input media asset into a plurality of media blocks. A media analyzer can analyze separately media content in each of the media blocks to determine respective encoding parameters for each of the media blocks based on a complexity for each of the respective media blocks. A plurality of encoders can encode or transcode, in parallel with each other, each of the media blocks based on the determined encoding parameters to generate an encoded media file in a target format.

Abstract: A disclosed method is performed at a system configured to distribute segment instances corresponding to segments of a media item. The method includes receiving, from a client device, a first segment request including data indicative of a first set of segments of the media item and data indicative of a first bitrate. The method further includes transmitting, to the client device in response to the first segment request, a first set of segment instances, each of the first set of segment instances including data encoding a respective one of the first set of segments at the first bitrate. The method includes generating, in response to the first segment request, a first prediction indicative of a first predicted set of segment instances, each of the first predicted set of segment instances including data encoding a segment of the media item subsequent to the first set of segments at one of a plurality of predicted bitrates.
