Digital network-based video tagging system
View Patent ↗A system for handling video tags. The tags are displayed synchronized to a video. A controller manages and modifies tag data that can be created by one or more users. The controller identifies a tag dataset for use with a video and provides information for synchronization and display of the tags. In a particular embodiment, features of a social-network website implementation are disclosed whereby a user community can post, filter, rate and display tags.
1. A method comprising:
obtaining an identification corresponding to a video;
receiving, based at least in part on the identification, an associated dataset from a location over a digital network, wherein the associated dataset includes:
display information describing visual design and placement of additional content at predetermined locations that, in response to playback of the video, overlap at least a portion of displayed video content to annotate items depicted within the displayed video content; and
synchronization information for displaying the additional content at predetermined times in response to playback of the video;
transferring the associated dataset to a playback engine for synchronized playback of at least a portion of the additional content with the video according to at least a portion of the synchronization information;
accepting a first modification to the associated dataset by a first user to produce a first modified dataset;
accepting a second modification to the first modified dataset by a second user to produce a second modified dataset, the second modification including a modification to the display information, to the synchronization information, or to both the display information and the synchronization information; and
transferring the second modified dataset to the playback engine for synchronized playback, with the video, of at least a portion of the additional content in accordance with information in the second modified dataset.
2. The method of claim 1 , wherein obtaining the identification comprises:
obtaining a predetermined identification corresponding to the video.
3. The method of claim 1 , wherein obtaining the identification comprises:
obtaining a predetermined identification embedded with a video file.
4. The method of claim 1 , wherein obtaining the identification comprises:
obtaining a predetermined identification embedded with a video stream.
5. The method of claim 1 , further comprising:
deriving the identification, at least in part, from data that includes at least a portion of the video.
6. The method of claim 5 , wherein deriving the identification comprises:
generating a hash value from the data.
7. The method of claim 5 , wherein deriving the identification comprises:
comparing multiple values in the data with multiple predetermined expected values.
8. The method of claim 7 , further comprising:
determining whether a statistical criterion is met based on the comparing multiple values in the data with the multiple predetermined expected values.
9. The method of claim 8 , wherein determining whether the statistical criterion is met comprises:
determining whether a threshold percentage of expected values at predetermined locations in the data is met.
10. The method of claim 1 , wherein obtaining the identification comprises:
accepting a signal from a user input device; and
obtaining the identification based at least in part on the signal from the user input device.
11. The method of claim 10 , wherein obtaining the identification based at least in part on the signal from the user input device comprises:
determining, in response to the signal, a filename.
12. The method of claim 11 , wherein accepting a signal from a user input device comprises accepting a signal that identifies the video and determining the filename comprises determining a filename associated with the video.
13. The method of claim 11 , wherein determining the filename comprises:
identifying the associated dataset corresponding to the filename.
14. The method of claim 1 , wherein receiving, based at least in part on the identification, the associated dataset comprises:
receiving multiple associated datasets configured to provide the additional content in synchronization with playback of the video.
15. The method of claim 1 , further comprising:
obtaining the video over the digital network.
16. The method of claim 1 , wherein obtaining the identification comprises:
obtaining a predetermined identification representing a listing in a directory structure readable by humans or automated processes.
17. The method of claim 1 , wherein obtaining the identification comprises:
obtaining a predetermined identification representing a binary value.
18. An apparatus comprising:
a hardware processor;
a machine-readable storage medium including one or more instructions executable by the hardware processor that configure the hardware processor to:
obtain an identification corresponding to a video;
receive, based at least in part on the identification, an associated dataset from a location over a digital network, wherein the associated dataset includes:
display information describing visual design and placement of additional content at predetermined locations that, in response to playback of the video, overlap at least a portion of displayed video content to annotate items depicted within the displayed video content; and
synchronization information for displaying the additional content at predetermined times in response to playback of the video;
transfer the associated dataset to a playback engine for synchronized playback of the additional content with the video
accept a first modification to the associated dataset by a first user to produce a first modified dataset;
accept a second modification to the first modified dataset by a second user to produce a second modified dataset, the second modification including a modification to the display information, to the synchronization information, or to both the display information and the synchronization information; and
transfer the second modified dataset to the playback engine for synchronized playback, with the video, of at least a portion of the additional content in accordance with information in the second modified dataset.
19. A non-transitory machine-readable storage medium including instructions executable by a hardware processor, the instructions comprising:
instructions to obtain an identification corresponding to a video;
instructions to receive, based at least in part on the identification, an associated dataset from a location over a digital network, wherein the associated dataset includes:
display information describing visual design and placement of additional content at predetermined locations that, in response to playback of the video, overlap at least a portion of displayed video content to annotate items depicted within the displayed video content; and
synchronization information for displaying the additional content at predetermined times in response to playback of the video;
instructions to transfer the associated dataset to a playback engine for synchronized playback of the additional content with the video;
instructions to accept a first modification to the associated dataset by a first user to produce a first modified dataset;
instructions to accept a second modification to the first modified dataset by a second user to produce a second modified dataset, the second modification including a modification to the display information, to the synchronization information, or to both the display information and the synchronization information; and
instructions to transfer the second modified dataset to the playback engine for synchronized playback, with the video, of at least a portion of the additional content in accordance with information in the second modified dataset.
