Abstract: To reduce, at the time of transmittingdisparity information sequentially updated within a period during whichsuperimposing information is displayed, the data amount of the disparityinformation. A segment including disparity informationsequentially updated during a subtitle display period is transmitted. Atthe reception side, disparity to be provided between a left eye subtitle andright eye subtitle can be dynamically changed in conjunction with change in thecontents of the image. This disparity information is updated based on adisparity information value of a first frame, and a disparity information valueat a predetermined timing where an interval period has been multiplied by amultiple value. The amount of transmitted data can be reduced, and alsoat the reception side, the amount of memory for holding the disparityinformation can be greatly conserved.

Abstract: Service compatibility with respect to a 2D TV is realized when transmitting frame compatible type stereoscopic image data. When the image data is frame compatible type stereoscopic image data, image region information for cropping image data for 2D display from the image data after decoding is inserted into a compressed video stream. In the 2D television receiving device (2D TV) of the receiving side,it is possible to crop image data for 2D display from the image data after decoding and to obtain 2D image data based on the image region information.

Abstract: A transmission apparatus configured to mix, at a mixing rate, pixels of first video data with pixels of peripheral frames of the first video data and obtain second video data at a first frame rate.　The mixing rate for each pixel of a frame of the first video data is based on a luminance value of the pixel.　The second video data includes frames having a second frame rate lower than the first frame rate. The apparatus encodes the frames having the second frame rate to obtain a basic stream and encodes remaining frames of the second video data to obtain an extended stream, inserts information about the mixing rate into the basic stream and the extended stream in association with each frame, and transmits the basic stream and the extended stream into which the information about the mixing rate has been inserted.
