DIGITAL BROADCAST TRANSMITTER AND DIGITAL BROADCAST RECEIVER

摘要

<P>PROBLEM TO BE SOLVED: To provide a digital broadcast transmitter and a digital broadcast receiver to transmit and receive additional information without degrading the quality of high-definition content. Ž<P>SOLUTION: A high definition encoder 110 encodes video data and voice data of content to be broadcasted with high definition quality. A low definition encoder 130 encodes the video data and the voice data of the content to be broadcasted with low definition quality. An embedding portion 140 inputs the content encoded by the low definition encoder 130 and a TMCC signal, and embeds the content into an expanded field of the TMCC signal.
