Transmission device, transmission method, reception device, and reception method
Abstract:
To transmit moving image data at a high frame rate in good condition, second moving image data at a predetermined frame rate is provided by processing first moving image data at the predetermined frame rate in units of consecutive N pictures (N is an integer larger than or equal to two), using an image data item provided by averaging the image data items of the N pictures as the image data item of a picture in the second moving image data, and using the image data items of N−1 pictures of the N pictures without change as the image data items of additional pictures in the second moving image data. A video stream is generated by encoding the image data item of each of the pictures in the second moving image data and the generated video stream is transmitted.
