Content-modification system with delay buffer feature

Abstract:

In one aspect, a method includes an input buffer receiving content; accessing the content from the input buffer and extracting from the accessed content, in-band message data that indicates a start time associated with a content-modification opportunity for a content-presentation device; the input buffer transmitting the content to a delay buffer; the delay buffer receiving the content from the input buffer and, after a delay time-period, transmitting the content to an output buffer; the output buffer receiving the content from the delay buffer and outputting for presentation a portion of the content; and after outputting for presentation the portion of the content and proximate a time-point associated with the indicated start-time, starting to perform a content-modification operation in connection with the content-modification opportunity.
