System and method for creating multiple versions of a descriptor file

摘要

A system (e.g., content management system, content delivery system) and method are described herein which are configured for receiving one or more source descriptor files (e.g., MPD files, HLS m3u8 files, HTTP manifest files) along with associated adaptive bit rate segments. The system and method are also configured for receiving rules (e.g., content ratings, timing information, user profiles, regional and demographic information) and then creating multiple descriptor files based on the received rules and the source descriptor file(s). The system and method are further configured for distributing the multiple descriptor files to one or more downstream systems (e.g., content to delivery systems, users).

1. A system configured for creating multiple descriptor files, the system comprising:
a processor; and a memory that stores processor-executable instructions therein where the processor interfaces with the memory and executes the processor-executable instructions to enable the following operations:
receiving one or more source descriptor files and associated adaptive bit rate segments for one or more master content files, wherein the one or more source descriptor files includes a media presentation which has multiple periods spliced together into specific time periods and refer to the associated adaptive bit rate segments;receiving rules which provide details on how the multiple descriptor files are to be created;creating the multiple descriptor files based on the rules and the one and more source descriptor files, wherein the multiple descriptor files include a media presentation based on the media presentation from the one or more source descriptor files, and wherein the creating operation is implemented by manipulating at least one of the one or more source descriptor files based on the rules without transcoding the one or more source descriptor files to an adaptive stream format and without generating new content files to create the multiple descriptor files; anddistributing one or more of the multiple descriptor files to one or more downstream systems.
