Japanese Patent JP7173028

B2

The present disclosure relates to a transmission apparatus, a transmission method, and a program that can transmit a moving image so as to be reproduced with lower latency.An encoding unit performs spatially scalable encoding on a moving image, and a transmission processing unit transmits a picture for each layer encoded by the encoding unit via a network. Then, in a case where a high possibility that underflow occurs in the reception buffer is predicted, or feedback indicating that underflow has occurred in the reception buffer is received, a reference layer control processing unit causes the encoding unit to limit a reference layer to an interlayer. The present technology can be applied to, for example, a transmission apparatus that codes and transmits a moving image.
