Abstract
The transmitting apparatus includes an encoder creating an encoded content signal by encoding the content, a generator generating sign language word identification information corresponding to chronologically-ordered sign language words appearing in a speech in the content, a creating unit creating control information containing the generated chronologically-ordered sign language word identification information, a storage unit storing sign language word images for displaying a sign language video corresponding to the sign language words by grouping the sign language word images into a plurality of modules according to a frequency of appearance of the sign language words in the speech in the content, a multiplexer creating a data stream by combining the encoded content signal with the control information and by repeatedly replicating the plurality of modules at a frequency corresponding to the frequency of appearance, and a transmitter transmitting the created data stream.
