Abstract

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.

Claims

1. A media monitoring system for receiving at least one video channel having corresponding closed captioned text in real time, comprising:

a storage medium for containing at least one of stored search terms for conducting an alert search and provided search terms for conducting an archival search;

a media management system for continuously storing all the data of the at least one video channel locally and for extracting the corresponding closed captioned text into decoded text, the decoded text being provided to a global storage database, the media management system having

a search engine for comparing the decoded text against at least one of the stored search terms and the provided search terms to provide matching results during the alert search and the archival search, and

an indexing engine for indexing units of the decoded text by time; and

a media server pod for receiving the at least one video channel and for locally storing the data of the at least one video channel, the media server pod including a close caption decoder for extracting the corresponding closed captioning text into the decoded text,

an index server for receiving the decoded text from the media server pod over a first network, the index servers having the index engine, and

a web server including the global storage database for storing the decoded text received from the index servers over a second network, the web servers having the search engine and a search term database for storing the at least one of stored search terms and provided search terms, and

a user access system for receiving and displaying the matching results, the user access system transmitting a request for stored data corresponding to specific units of the decoded text from the media management system, the media management system providing said stored data corresponding to specific units of the decoded text in response to the request.

2. The media monitoring system of claim 1, wherein the media server pod includes at least one media source for providing the at least one video channel, and a media server in direct communication with the at least one media source for receiving the at least one video channel, the media server having a decoder for extracting the corresponding closed captioned text into decoded text from a vertical blanking interval of the at least one video channel, the media server including mass storage media for storing the data of the at least one video channel.

3. The media monitoring system of claim 2, wherein the media server includes a parser for generating the stored data corresponding to specific units of the decoded text.

4. The media monitoring system of claim 2, wherein the media server pod includes a plurality of media sources for providing a corresponding number of video channels.

5. The media monitoring system of claim 2, wherein the media server includes a video/audio compression system for compressing the data of the at least one video channel prior to storage onto the mass storage media.

6. The media monitoring system of claim 5, wherein the media server includes a speech-to-text system for converting audio signals corresponding to the at least one video channel into text.

7. The media monitoring system of claim 5, wherein the media server includes a text detector for detecting an absence of the corresponding closed captioned text, the text detector generating an alert indicating the absence of the corresponding closed captioned text.

8. The media monitoring system of claim 2, wherein the media source includes one of a satellite receiver, a cable box, an antenna, and a digital radio source.

9. The media monitoring system of claim 1, wherein the index server includes the global storage database.

10. The media monitoring system of claim 1, wherein the web server includes the global storage database.

11. The media monitoring system of claim 2, wherein the first network includes a wide area network.

12. The media monitoring system of claim 11, wherein the media management system further includes a second media server pod for receiving data of a different video channel, the second media server pod being in communication with the first network.

13. The media monitoring system of claim 12, wherein the media server pod and the second media server pod are geographically distant from each other.

14. The media monitoring system of claim 1, wherein the user access system includes a duplicate video clip detector for identifying the matching results that are duplicates of each other.

15. The media monitoring system of claim 1, wherein the user access system includes a user access device in communication with the web server over a third network, for receiving and displaying the matching results.

16. The media monitoring system of claim 15, wherein the user access system includes a fourth network in communication with the user access device and the media server pod, the user access device receiving said stored data corresponding to specific units of the decoded text in response to the request over the fourth network.

17. The media monitoring system of claim 15, wherein the user access device provides the at least one of the stored search terms and the provided search terms to the media management system.
