TRANSMITTING APPARATUS, TRANSMITTING METHOD, RECEIVING APPARATUS, AND RECEIVING METHOD

摘要

The luminance atmosphere that the creator intends is excellently reproduced on the receiving end.　The transmission video data is obtained by applying a predetermined opto-electrical transfer function to the input video data.　The transmission video data is transmitted together with the luminance conversion acceptable range information about a set region in the screen.　For example, a transmitting unit transmits a video stream obtained by encoding the transmission video data while inserting the luminance conversion acceptable range information into a layer of the video stream.　The receiving end obtains display video data by applying an electro-optical transfer function corresponding to the predetermined opto-electrical transfer function to the transmission video data, and performing a luminance conversion process in each of the set regions independently in accordance with the luminance conversion acceptable range information.
