Abstract: The present invention relates to a playback apparatus, a method, and a program which can appropriately perform jump playback when content transmitted through a network is played back in real time. A terminal 3 receives stream data transmitted from a server 1, buffers the stream data, and plays back the buffered data. The terminal 3 has multiple buffers to allow content data of the positions of jump destinations that can be specified as a jump destination during jump playback to be pre-buffered in the multiple buffers. As a result, upon receiving a request for jump playback, the terminal 3 can start playback from a jump destination without delay, since the data of the jump destination has already been buffered. The present invention is applied to, for example, television receivers.
