A method, apparatus, and system are described for a continuous speech recognition engine that includes a fine speech recognizer model, a coarse sound representation generator, and a coarse match generator. The fine speech recognizer model receives a time coded sequence of sound feature frames, applies a speech recognition process to the sound feature frames and determines at least a best guess at each recognizable word that corresponds to the sound feature frames. The coarse sound representation generator generates a coarse sound representation of the recognized word. The coarse match generator determines a likelihood of the coarse sound representation actually being the recognized word based on comparing the coarse sound representation of the recognized word to a database containing the known sound of that recognized word and assigns the likelihood as a robust confidence level parameter to that recognized word.

A system and method for computerized searching for items of interest contained in visual media assets, such as a movie or video, stores digital tag information for tagged visual media assets which includes for each tag a time code for a representative image frame, an address code for the storage location of a captured image-still of the frame, and one or more keywords representing the item(s) of interest or their characteristics. When a search request is entered with keywords for items of interest, the search result lists entries from tags containing those keywords, and can also display the captured image-stills (or thumbnail photos thereof) as a visual depiction of the search results. The search service enables advertisers and vendors to bid on rights to link their advertising and other information displays to the search results. The search service can also be used for playback of clips from media assets to viewers on a video viewing website or on a networked playback device.

Methods and apparatus for broadcasting high quality audio “studio direct” with the same digital information employed in the studio by the video producer with AC-3 digital audio signals for broadcast to integrated receiver decoders (IRD). The methods and apparatus permit proper handling of AC-3 data by switching signals to encoders in response to detection of the encoded signals representing compression of the data. Control over individual data bits such as copyright bits is maintained by determining the bit status, comparing it to a preferred status, changing the status if it does not comply with the preferred status, and reevaluating cyclical redundancy check value in each data packet to avoid disruption in the data transmission. In addition, the system includes an uplink device which automatically checks, logs and reports errors in Dolby Digital AC-3 signals by a monitor which employs a processor, a digital audio card and an SMPTE timecode reader. As an option, an ethernet interface may be provided to permit AC-3 transmission to expedite storage and transmission of the audio data by media such as compact disks. The monitor employs a state machine that finds AC-3 packets, locks into the packets and detects discontinuities or loss of signal. The monitor then computes and checks the cyclical redundancy check value of the AC-3 packet found. In addition, the system enables the device to play AC-3 signals such as Dolby Digital out in sync with video signals, regardless of the storage media for the files. A sound card having an input for receiving house reference AES clock pulses enables the AES clock of the playback signal to be locked to the frequency of a production house master as a time code reader or an editor's contact closure match video and audio signals playback.

The invention provides an editing system for editing and combining media material into a resulting media composition. The media may be film or video based material, and also may include audio material. The video may adhere to either NTSC or PAL timing. In response to editing instructions, an Edit Decision List (EDL) is produced that specifies the material that makes up the edited composition, and the order of presentation of this material in the output composition. The EDL specifies the input clips that are taken from the source material using source timecode and similarly defines the output order again according to a new time code, the record time code. The editing system produces an extended EDL that facilitates the downstream processing (after the editing has been completed) for post production tasks requiring the need to know accurately where edit points occur.
