Abstract

A content streaming system and methodology for facilitating the management of content streaming. A video packaging and origination service receives streaming content that is organized according to content segments. Individual content segments will be encoded according to a plurality of encoding profiles and received at different ingress nodes within video packaging and origination service. The video packaging and origination service receives requests for streaming content from requesting entities. Sets of encoded content segments are transmitted by egress nodes.

Claims22

Dependent claims

A system to manage streaming content comprising:

one or more computing devices associated with a content management service, wherein the one or more computing devices of the content management service are configured to select an ingress node from a set of available ingress nodes based on attributes of at least one of a content provider and the one or more computing devices of the content management service;
one or more computing devices associated with the set of available ingress nodes, wherein the selected ingress node is configured to provide encoded segments and deterministic data defining characteristics of the encoded segments, the encoded segments corresponding to encoding profiles based on bitrate and encoding format combinations, and the deterministic data including at least one of timestamp information, a sequence number, and a time of operation of an encoder;
the one or more computing devices of the content management service further configured to select an egress node from a set of available egress nodes based on attributes of at least one of a requesting entity and the one or more computing devices of the content management service;
and
one or more computing devices associated with the set of available egress nodes, wherein the selected egress node is configured to:
receive a request for streaming content from the requesting entity;
access an index to identify a set of encoded content segments corresponding to the received streaming content request, wherein the index is based on the deterministic data provided by the individual ingress nodes;
package the identified set of encoded content segments;
and
transmit the packaged set of encoded content segments.
