Abstract: In one aspect, a method is disclosed. The method includes identifying, by a content-presentation device, an upcoming content modification opportunity on an identified channel, where the identified upcoming content modification opportunity relates to a modifiable content-segment. The method also includes receiving, by the content-presentation device, the modifiable content-segment. The method further includes performing, by the content-presentation device, a set of operations to prepare the content-presentation device to perform a content-modification operation in connection with the identified upcoming content modification opportunity on the identified channel. The method additionally includes receiving, by the content-presentation device, an instruction to operate in a test mode. The method also includes responsive to receiving the instruction, outputting, by the content-presentation device, for presentation the modifiable content-segment without a modification that relates to supplemental content.

Abstract: In one aspect, a method includes identifying a group of multiple content-presentation devices that are tuned to the same channel and that are each scheduled to perform, at a modification start-time, a respective content-modification operation that comprises modifying a modifiable content-segment in connection with an upcoming content-modification opportunity on the channel. The method also includes determining that, after the modification start-time, at least a subgroup of the group of content-presentation devices have detected a mismatch between reference fingerprint data representing the modifiable content-segment and query fingerprint data representing content received by at least the subgroup of content-presentation devices.

Abstract: In one aspect, a method includes receiving a first request for first supplemental content for use by a content-presentation device in performing a first content-modification operation, receiving a second request for second supplemental content for use by a tuner device in performing a second content-modification operation. The method also includes determining that the content-presentation device is connected to the tuner device, and based at least in part on the first and second requests, determining that the first and second requests are associated with the same modifiable content-segment, and, in response to the determinations, using one or more parameters as a basis to select for performance an action from a set of actions including a first action that facilitates performance of the first content-modification operation and a second action that facilitates performance of the second content-modification operation.

Abstract: In one aspect, a method includes receiving query fingerprint data representing content received by a content-presentation device. The method also includes comparing at least a first portion of the query fingerprint data with at least one first reference fingerprint data set, where each first reference fingerprint data set corresponds with a respective channel. The method also includes determining that the query fingerprint data does not match any of the at least one first reference fingerprint data sets. The method also includes responsive to the determining, comparing at least a second portion of the query fingerprint data with second reference fingerprint data representing a modifiable content-segment. The method also includes detecting a match between at least the second portion of the query fingerprint data and the second reference fingerprint data.

Abstract: In one aspect, a method is for use in connection with a content-modification system that includes a content-distribution system and a content-presentation device.

Abstract: In one aspect, a method includes (i) accessing broadcast-schedule data associated with a channel; (ii) using the accessed broadcast-schedule data to identify an upcoming content-modification opportunity on the channel; (iii) responsive to identifying the upcoming content-modification opportunity on the channel, identifying a content-presentation device tuned to the channel; and (iv) causing supplemental content to be transmitted to the identified content-presentation device, to facilitate the identified content-presentation device performing a content-modification operation related to the identified upcoming content-modification opportunity on the channel.

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.

Abstract: In one aspect, a method is performed by a computing system that is in communication with a content-presentation device, where the content-presentation device is scheduled to perform, at a modification start-time, a content-modification operation that comprises modifying a modifiable content-segment that the content-presentation device is scheduled to receive. The method includes determining that the content-presentation device has detected, within a predefined time period after the modification start-time and during performance of the content-modification operation, a mismatch between reference fingerprint data representing the modifiable content-segment and query fingerprint data representing content received by the content-presentation device from a tuner device connected to the content-presentation device.

Abstract: In one aspect, a method includes receiving, by a content-management system and from a content-presentation device, a request for supplemental content, such as a replacement advertisement. The content-management system may then determine a technical characteristic of the content-presentation device and select supplemental content based at least in part on at least the determined technical characteristic of the content-presentation device. The content-management system may then cause the selected supplemental content to be transmitted to the content-presentation device to facilitate the content-presentation device performing a content modification operation.
