Restoring program information for clips of broadcast programs shared online

摘要

To restore context information about a clip that was sampled from a broadcast program, the clip is identified by matching a digital fingerprint of the clip against a database of known digital fingerprints taken from broadcast programs. If the clip can be identified, it is then associated with information about the matching broadcast program. The loss of context data about the clip obtained from a broadcast program is thus remedied, enabling media content available online to be more useable for a variety of purposes, such as media searching, automatic broadcast attribution, and targeting advertisements.

主权项

1. A method comprising:
identifying, by a computer, a clip available on an online clip sharing system, the clip containing metadata about the clip and at least a portion of a broadcast program; obtaining, by the computer, a digital fingerprint for the clip; matching, by the computer, the digital fingerprint of the clip against a plurality of reference fingerprints to identify the broadcast program in the clip, the reference fingerprints corresponding to a plurality of known broadcast programs; obtaining, by the computer, program information associated with the identified broadcast program based at least in part on the matching of the digital fingerprint of the clip against the plurality of reference fingerprints; associating, by the computer, the program information with the clip; storing, by the computer, the program information in association with the clip in a non-transitory computer-readable storage medium; comparing, by the computer, a portion of the metadata about the clip with the program information; assigning, by the computer, the metadata as trustworthy if the portion of the metadata about the clip matches the program information; assigning, by the computer, the metadata as untrustworthy if the portion of the metadata about the clip does not match the program information; and transmitting, by the computer to a user device for display, a measure of trustworthiness comprising whether the metadata was assigned as trustworthy or untrustworthy.
