Method and apparatus for the aggregation and selective retrieval of television closed caption word content originating from multiple geographic locations
First Claim
1. A system for the aggregation and selective retrieval of television word content from closed captioned text streams, comprising:
- (a) tuner means to receive one or more television signals;
(b) decoder means operatively connected to said tuner means to decode closed captioned text streams in one or more television signals and to write said decoded closed captioned text streams to a file;
(c) closed caption text collection and transmission means from one or more local clients and/or servers to one or more remote central server means;
(d) means for conditioning the collected closed captioned text to impose format consistency across all text files regardless of origin;
(e) closed captioned text file management and user interface means; and
(f) central server means operatively connected to said decoder means to store said file and make said file available to a user of said system.

Abstract
A method for compiling and searching the word content of multiple television news programs uses closed captioning text encoded in the television signal. A remotely located server, using a closed captioning decoder, extracts a closed captioned text stream from a television signal and writes the text stream to a file according to parameters pre-programmed by the system administrator. A completed text file moves, via the Internet, from the remote central server to a central server. At the central server, the text file encounters a series of pre-index processes designed to impose consistency across all sources. Text files are parsed into smaller files by story or segment. The resulting multiple files are indexed by content and origination information. An interface for submitting search parameters is provided through a World Wide Web site. The site provides web pages to allow search parameters to be specified by a user. The results of a search are web pages displaying sentences and their citations that meet the specified search parameters. Associated with each cited sentence is an option allowing the user to view the full text of the newscast story or segment from which the cited sentence is derived. The web site also provides a feature called Auto Alert that allows the user to pre-specify search parameters for ongoing, automatic submission to the index server each time a new text file is received. The results of Auto Alert are e-mailed to the user, either instantly or according to a user-defined schedule.

1. means for determining useful data in a closed captioned text file;
2. means for identifying symbols indicating the beginning of a new story within a file;
3. means for identifying multiple time stamps uninterrupted by text;
4. means for breaking the closed captioned text streams into smaller files using information from (b) and (c); and
5. means for separately saving the smaller files.
-
-
7. A system, as defined in claim 5, wherein said preprogrammed parameters are furnished by said user of said system via electronic communication means.
-
8. A system, as defined in claim 5, wherein said decoded closed captioned text streams are indexed, and delivered to said user automatically according to preprogrammed parameters via electronic communication means.
-
10. A method, as defined in claim 8, further comprising parsing said closed captioned text stream into its unique story parts and saving the unique story parts to separate program files for later retrieval.
-
11. A method, as defined in claim 10, wherein the step of parsing includes:

-
12. A method, as defined in claim 8, further comprising indexing words in said decoded closed captioned text streams written in the file.
-
13. A method, as defined in claim 8, further comprising making said file available to said user of said method via electronic communication means.
-
14. A method, as defined in claim 13, further comprising said user of said method furnishing said preprogrammed parameters via electronic communication means.
-
15. A method, as defined in claim 8, wherein said decoded closed captioned text streams are written to the file according to preprogrammed parameters.
-
16. A method, as defined in claim 8, wherein said decoded closed captioned text streams are delivered to said user according to preprogrammed parameters.
-
9. A method for aggregation and selective retrieval of television word content from closed captioned text streams, comprising:
-
(a) receiving one or more television signals;
