A digital media recorder and a method of controlling such are provided. During attempts to copy media content, sub-sequences are extracted from an input media sequence. A digital fingerprint of the sub-sequence is calculated and compared with at least one first reference fingerprint from a database. The outcome of the comparison determines the action to take in the further processing. Recording of the input media sequence on a media carrier is either allowed or obstructed, e.g. disallowed. In the case recording of the sequence is allowed, the database is updated with information that the digital media sequence has been recorded.

A multimedia search and indexing system automatically selects scenes or events of interest from any media, i.e., video, film, sound for replay, in whole or in part, in other contexts. The entire audio track of a recorded event in video, film, sound, etc., is analyzed to determine audio levels within a set of frequency ranges of interest. Audio clip levels within the selected frequency ranges are chosen as audio cues representative of events of interest in the track. The selection criteria are applied to the audio track of the recorded event. An Edit Decision List (EDL) is generated from the analysis of the audio track. The list is representative of scenes or sounds of interest as clips for reuse. The clips are reviewed and accepted or rejected for reuse. Once selected, the clips are edited using industry standard audio and video editing techniques.

Thereby, its reproducing processing without limitation over the reproducible period of time can be surely prevented.

A technique to prevent illicit copying of a copy-protected CD-ROM into a computer-readable storage drive is presented. In accordance with the present invention, when an authentic copy-protected CD-ROM is inserted into a CD drive and the content of the copy-protected CD-ROM is installed onto a hard disk drive that is linked to the CD drive, the Central Processor Unit (CPU) executes the installer instructions residing in the CD-ROM to create a license file in the hard disk drive. For security reasons, the content of the CD-ROM (e.g., the executable file of the application) is encrypted. When the content of the CD-ROM is copied into the hard disk drive, it remains encrypted. The license file essentially acts as a timer to monitor a predetermined time interval that has been programmed into the license file. If a user attempts to launch the encrypted copied application residing in the hard drive at any time prior to the expiration of the predetermined time interval, the license file readily supplies the key code to enable a filter to decode the encrypted installed application thereby allowing the application to launch. At the expiration of the predetermined time interval, the license file withholds the key code therefore not allowing the installed application to be decrypted and successfully launched. The predetermined time interval can be reset by reinserting the copy-protected CD-ROM into the CD drive to reset the time interval.
