System and method for closed caption data translation
First Claim
1. A system for translating closed caption data in a program signal during broadcast of said program signal, said program signal comprising closed caption codes and closed caption text in a source language, comprising:
- a closed caption decoder for receiving said program signal and preprocessing said program signal for translation by extracting from said program signal said closed caption codes and closed caption text in said source language;
a server for(i) receiving said closed caption codes and said closed caption text in said source language from said closed caption decoder;
(ii) pre-editing said closed caption text in said source language to change content in said caption text for submission to machine translation software and(iii) translating said pre-edited text in said source language to closed caption text in a target language using said machine translation software and said pre-edited text; and
a device for receiving said closed caption codes and said closed caption text in said target language from said server, inserting said closed caption codes and said closed caption text in said target language in said program signal, and transmitting said program signal to a program destination for broadcast to all viewers of said program signal, wherein viewers that select a closed caption viewing option on their televisions during broadcast of said program signal may view said closed caption text in said target language.

Abstract
A system and method is disclosed for translating closed caption data from a source language to a target language during a broadcast. The system and method are fully automated to provide accurate and timely translations of closed caption data. The system and method include a text flow management process and a pre-editing process that may be used in conjunction with any machine translation system. The text flow management process facilitates the input of closed caption data in a source language from a program source to the output of closed caption data in a target language to a program destination. The pre-editing process improves the quality of translation performed by machine translation software by addressing various problems associated with real-time translation of closed caption data.

8. A method for translating closed caption data in program source signals during broadcast of said program source signals, said program source signals comprising closed caption codes and closed caption text in a source language, comprising the steps of:
-
receiving said program source signals; decoding closed caption codes and closed caption text from said closed caption data in said program source signals; pre-editing said closed caption text in to change content in said closed caption text for submission to machine translation software; translating said pre-edited text in said source language to target language text using said machine translation software and said pre-edited text; inserting said closed caption codes and said target language text in program destination signals to produce closed caption text in said target language; and broadcasting said program destination signals to a program destination for broadcast to all viewers of said program destination signals, wherein viewers that select a closed caption viewing option on their receivers during broadcast of said program destination signals may view said closed caption text in said target language. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An apparatus for translating closed caption data comprising closed caption codes and closed caption text in a source language comprising:
-
a server adapted to (i) receive said closed caption codes and said closed caption text in said source language from a program broadcast during broadcast of said program; (ii) translate said closed caption text in said source language to closed caption text in a target language; (iii) insert said closed caption codes and said closed caption text in said target language in program destination signals; (iv) transmit said program destination signals with said closed caption text in said target language to a device for broadcast of said program destination signals with said closed caption text in said target language to a program destination, wherein viewers of said program destination signals that select a closed caption viewing option on their receivers during broadcast of said program destination signals may view said closed caption text in said target language; pre-editing software on said server for changing content of said closed caption text in said source language for submission to machine translation software; and machine translation software on said server for translating said pre-edited text in said source language to closed caption text in said target language. - View Dependent Claims (17, 18, 19)
