A method and system for continually storing and cataloguing streams of broadcast content, allowing real-time searching and real-time results display of all catalogued video. A bank of video recording devices store and index all video content on any number of broadcast sources. This video is stored along with the associated program information such as program name, description, airdate and channel. A parallel process obtains the text of the program, either from the closed captioning data stream, or by using a speech-to-text system. Once the text is decoded, stored, and indexed, users can then perform searches against the text, and view matching video immediately along with its associated text and broadcast information. Users can retrieve program information by other methods, such as by airdate, originating station, program name and program description. An alerting mechanism scans all content in real-time and can be configured to notify users by various means upon the occurrence of a specified search criteria in the video stream. The system is preferably designed to be used on publicly available broadcast video content, but can also be used to catalog private video, such as conference speeches or audio-only content such as radio broadcasts.

According to one embodiment, a method for blocking scenes with objectionable content comprises receiving incoming content, namely a scene of a program. Thereafter, using closed captioning information, a determination is made if the scene of the program includes objectionable content, and if so, blocking the scene from being displayed.

A system, method, and computer program product for automatically analyzing multimedia data audio content are disclosed. Embodiments receive multimedia data, detect portions having specified audio features, and output a corresponding subset of the multimedia data and generated metadata. Audio content features including voices, non-voice sounds, and closed captioning, from downloaded or streaming movies or video clips are identified as a human probably would do, but in essentially real time. Particular speakers and the most meaningful content sounds and words and corresponding time-stamps are recognized via database comparison, and may be presented in order of match probability. Embodiments responsively pre-fetch related data, recognize locations, and provide related advertisements. The content features may be also sent to search engines so that further related content may be identified. User feedback and verification may improve the embodiments over time.

Interactive content preservation and customization technology is placed at the broadcast facility to ensure reliable transmission of the interactive content to a local subsystem. An interactive content code detector detects interactive content codes in the video stream at the broadcast facility. The interactive content code detector is placed in the transmission path before the video stream is transmitted to broadcast facility hardware that may strip out, destroy, corrupt or otherwise modify the interactive content and interactive content codes. Once an interactive content code detector detects a code, an interactive broadcast server determines what action to take, and instructs an data insertion unit accordingly. The interactive content codes or interactive content may be placed in a portion of the video that is guaranteed by the broadcast facility to be transmitted, for example, the closed caption region of the vertical blanking interval.

In a system and method providing a video with closed captioning, a processor may: provide a first website user interface adapted for receiving a user request for generation of closed captioning, the request referencing a multimedia file provided by a second website; responsive to the request: transcribe audio associated with the video into a series of closed captioning text strings arranged in a text file; for each of the text strings, store in the text file respective data associating the text string with a respective portion of the video; and store, for retrieval in response to a subsequent request made to the first website, the text file and a pointer associated with the text file and referencing the text file with the video; and / or providing the text file to an advertisement engine for obtaining an advertisement based on the text file and that is to be displayed with the video.

A Closed Caption Telephony Portal (CCTP) computer system that provides real-time online telephony services that include utilizing speech recognition technology to extend telephone communication through closed captioning services to all incoming and outgoing phone calls. Phone calls are call forwarded to the CCTP system using services provided by a telephone carrier. The CCTP system is completely transportable and can be utilized on any computer system, Internet connection, and standard Internet Browser. Employing an HTML / Java based desktop interface, the CCTP system enables users to make and receive telephone calls, receive closed captioning of conversations, provide voice dialing and voice driven telephone functionality. Additional features allow call hold, call waiting, caller id, and conference calling. To use the CCTP system a user logs in with his or her username and password and this process will immediately set up a Virtual Private Network (VPN) between the client computer and the server.

A system for performing closed captioning enables a caption prepared remotely by a captioner to be repositioned by someone other than the captioner, such as by a program originator. This capability is particularly useful when, for example, the program originator wishes to include a banner in a video but also wishes to avoid having a closed caption interfere with the banner. In one illustrative system, the program originator is a broadcast station that includes a conventional encoder and a broadcast station computer. In one arrangement, control data generated at the station computer is incorporated into the caption data by the station computer. In another arrangement, the control data is sent from the station computer to the captioner computer, which incorporates the control data into the caption data.

In a system and method of producing time-synchronous textual descriptions of stage directions in live or pre-recorded productions to provide assistive program descriptions to visually-impaired consumers, a processor may parse stage directions from a production script and synchronize the parsed stage directions with closed captioning streams. The method may include viewing a live or pre-recorded production, creating textual descriptions of the stage directions using a stenography system, and outputting the textual descriptions to a separate output stream than that of dialogue descriptions. In addition, the method may include creating audio descriptions of the stage directions, and converting the audio descriptions to textual descriptions of the stage directions using a voice-recognition system. Further, the method may include distributing the synchronized stage directions, and receiving and decoding the synchronized stage directions using a text-based system.

Video navigation is provided where a video stream encoded with captioning is received. A user-searchable captioning index comprising the captioning and synchronization data indicative of synchronization between the video stream and the captioning is generated. In illustrative examples, the synchronization is time-based, video-frame-based, or marker-based.

Method, systems, and computer program products for synchronizing text with audio in a multimedia file, wherein the multimedia file is defined by a timeline having a start point and end point and respective points in time therebetween, wherein an N-gram analysis is used to compare each word of a closed-captioned text associated with the multimedia file with words generated by an automated speech recognition (ASR) analysis of the audio of the multimedia file to create an accurate, time-based metadata file in which each closed-captioned word is associated with a respective point on the timeline corresponding to the same point in time on the timeline in which the word is actually spoken in the audio and occurs within the video.
