Methods, apparatus and articles of manufacture to provide secondary content in association with primary broadcast media content
Example methods disclosed herein include accessing a secondary content schedule based on one or more watermarks detected in primary media content, the secondary content schedule to identify (i) one or more secondary content items and (ii) one or more first time values associated with the one or more secondary content items. Disclosed example methods also include comparing the one or more first time values associated with the one or more secondary content items in the secondary content schedule to second time values provided by a clock to determine whether to present a first one of the one or more secondary content items, the second time values based on a timestamp associated with the one or more watermarks detected in the primary media content. Disclosed example methods further include causing a media presentation device to display the first one of the secondary content items according to the secondary content schedule.
1. A non-transitory computer readable medium comprising computer readable instructions that, when executed, cause a processor of a media presentation device to at least:
compare a second identifier in a second media watermark detected in primary media content to a first identifier in a preceding first media watermark detected in the primary media content;
in response to the second identifier in the second media watermark having changed relative to the first identifier in the preceding first media watermark, access a secondary content schedule based on the second identifier and a timestamp in the second media watermark detected in the primary media content, the secondary content schedule to identify (i) one or more secondary content items and (ii) one or more first time values associated with the one or more secondary content items;
set an initial output time value of a clock to correspond to the timestamp in the second media watermark detected in the primary media content to synchronize the clock to permit identification of locations in the primary media content;
compare the one or more first time values associated with the one or more secondary content items in the secondary content schedule to second time values provided by the clock after synchronization to determine whether to present a first one of the one or more secondary content items; and
cause the media presentation device to present the first one of the secondary content items according to the secondary content schedule.
2. The non-transitory computer readable medium of claim 1 , wherein the primary media content includes video content and the first and second media watermarks are detected from the video content.
3. The non-transitory computer readable medium of claim 1 , wherein to cause the media presentation device to display the first one of the secondary content items according to the secondary content schedule, the instructions, when executed, cause the processor to instruct the media presentation device to display the first one of the one or more secondary content items when a first one of the second time values corresponds to a time defined by a first one of the one or more first time values associated with the first one of the one or more secondary content items.
4. The non-transitory computer readable medium of claim 1 , wherein the instructions, when executed, cause the processor to retrieve the first one of the one or more secondary content items from a remote server.
5. The non-transitory computer readable medium of claim 4 , wherein the instructions, when executed, cause the processor to store the first one of the one or more secondary content items in memory of the media presentation device.
6. A media presentation device comprising:
memory including computer readable instructions; and
a processor to execute the instructions to at least:
compare a second identifier in a second media watermark detected in primary media content to a first identifier in a preceding first media watermark detected in the primary media content;
in response to the second identifier in the second media watermark being different from the first identifier in the preceding first media watermark, access a secondary content schedule based on the second identifier and a timestamp in the second media watermark detected in the primary media content, the secondary content schedule to identify (i) one or more secondary content items and (ii) one or more first time values associated with the one or more secondary content items;
set an initial output time value of a clock to correspond to the timestamp in the second media watermark detected in the primary media content to synchronize the clock to permit identification of locations in the primary media content;
compare the one or more first time values associated with the one or more secondary content items in the secondary content schedule to second time values provided by the clock after synchronization to determine whether to present a first one of the one or more secondary content items; and
cause the media presentation device to present the first one of the secondary content items according to the secondary content schedule.
7. The media presentation device of claim 6 , wherein the primary media content includes video content and the first and second media watermarks are detected from the video content.
8. The media presentation device of claim 6 , wherein to cause the media presentation device to display the first one of the one or more secondary content items according to the secondary content schedule, the processor is to instruct the media presentation device to display the first one of the one or more secondary content items when a first one of the second time values corresponds to a time defined by a first one of the one or more first time values associated with the first one of the one or more secondary content items.
9. The media presentation device of claim 6 , wherein the processor is to retrieve the first one of the one or more secondary content items from a remote server.
10. The media presentation device of claim 9 , wherein the memory is first memory, and further including second memory, the processor to store the first one of the one or more secondary content items in the second memory of the media presentation device.
11. A method comprising:
comparing a second identifier in a second media watermark detected in primary media content to a first identifier in a preceding first media watermark detected in the primary media content;
in response to the second identifier in the second media watermark having changed relative to the first identifier in the preceding first media watermark, accessing, by executing an instruction with a processor of a media presentation device, a secondary content schedule based on the second identifier and a timestamp in the second media watermark detected in the primary media content, the secondary content schedule to identify (i) one or more secondary content items and (ii) one or more first time values associated with the one or more secondary content items;
setting, by executing an instruction with the processor, an initial output time value of a clock to correspond to the timestamp in the second media watermark detected in the primary media content to synchronize the clock to permit identification of locations in the primary media content;
comparing, by executing an instruction with the processor, the one or more first time values associated with the one or more secondary content items in the secondary content schedule to second time values provided by the clock after synchronization to determine whether to present a first one of the one or more secondary content items; and
causing, by executing an instruction with the processor, the media presentation device to present the first one of the secondary content items according to the secondary content schedule.
