Patent ID: 8330864

Claim:
A computer implemented method for combining multi-lingual closed caption data streams into a single output signal for transmission to an end user, comprising the steps of: receiving at a multiplexing system computer a broadcast signal comprising audio visual data; simultaneously transmitting data signals from said multiplexing system computer to a plurality of closed caption translation data generating systems; receiving at said multiplexing system computer closed caption translation data streams from each of said closed caption translation data generating systems, wherein said closed caption translation data streams each comprises a translation of data in said audio visual data into a language that is different from an original language of said audio visual data, and wherein each of said closed caption translation data streams is generated by its respective closed caption translation data generating system independent of all other of said closed caption translation data generating systems; and transferring said closed caption translation data streams to a closed caption data encoder for encoding said closed caption data streams into a single, multiple translation closed caption data output signal that forms a part of a composite audio visual stream for television broadcast transmission to all end user receivers of said television broadcast transmission.
