System and method for providing a digital watermark
摘要:
A method for capturing a broadcast is disclosed. The method for capturing a broadcast includes detecting an approximate start time of the broadcast, wherein said detecting includes monitoring for a broadcast trigger, identifying the broadcast and a timed length thereof, such that, based on the timed length and the approximate start time, an approximate end time may be calculated, and recording the broadcast from the trigger to the approximate end time, wherein said recording has captured the broadcast of radio advertising.
