Method and system for inserting content into streaming media at arbitrary time points

摘要

The present invention teaches a method and system of inserting content into streaming media programs without requiring re-encoding and/or re-segmenting of the program, thus allowing the insertion point within the media program to be selected as desired. The system and method operate on the relevant chunks of the streaming program to repackage those chunks, even in real time, to provide a chunk boundary at the desired insertion point in the streamed program to permit seamless playback of the main program and inserted content.

主权项

1. A method for inserting content, comprising:
receiving, by a stream repackager executing on one or more processors, streaming content defined by a program manifest comprising a plurality of resource identifiers of a corresponding plurality of chunks; identifying, by the stream repackager, a chunk of the streaming content including data to render the streaming content at a specified time point, the specified time point between an initial time point of the chunk and an end time point of the chunk; splitting, by the stream repackager, the identified chunk to form a first replacement chunk and a second replacement chunk, the first replacement chunk comprising the data of the identified chunk to render the streaming content from the initial time point to the specified time point and the second replacement chunk comprising the data of the identified chunk to render the streaming content from the specified time point to the end time point; and updating, by the stream repackager, the program manifest to replace a resource identifier corresponding to the identified chunk with resource identifiers corresponding to the first replacement chunk and second replacement chunk.
