Abstract: A computer-implemented method includes receiving from content presentation devices a request for supplemental content. Each content presentation device is configured to present program content received from a content distribution system. The program content is associated with a program schedule that specifies an advertisement start time. The computing system determines a supplemental content processing time that corresponds to an amount of time required by a particular content presentation device to receive the supplemental content to facilitate presentation of the supplemental content. The computing system schedules the content presentation devices to receive requested supplemental content according to corresponding supplemental content processing times and advertisement start times.

Abstract: In one aspect, a method includes a content-presentation device determining first and second intervals during which presentation of received content is modifiable, and transmitting first and second requests for first and second supplemental content. A link to content in a playlist may be received, the playlist including first supplemental content followed immediately by second supplemental content. The link may be used to retrieve the first supplemental content, which may be presented in a first modification operation during the first interval. Before completing the first modification operation, the content-presentation device may use the link to start retrieving the second supplemental content for a second modification operation scheduled immediately following the first modification operation, and may determine that while less than a threshold portion of the first modification operation remains incomplete, retrieval of the second supplemental content is also incomplete.

Abstract: In one aspect, a method includes receiving first content at a content-presentation device and presenting the first content, the first content comprising a first audio-content component. The content-presentation device may receive second content comprising a second audio-content component. The content-presentation device may determine a switch time at which to switch from presenting the first content to presenting the second content. During a first time interval prior to the switch time and ending at the switch time, the volume of the first audio-content component may be decreased to zero. At the switch time, the content-presentation device may switch from presenting the first content to presenting the second content. During a second time interval beginning at the switch time and ending at a second time after the switch time, the volume of the second audio-content component may be increased from zero to a non-zero volume level.
