The present technology relates to a transmission apparatus and a transmission method, a reception apparatus and a reception method, a transmission system, and a program by which a bandwidth is efficiently used such that power saving can be realized even if transmission of any stream is stopped in transmitting and receiving a plurality of streams formed of visible image data in accordance with a standard in DisplayPort (trademark).;In transmitting a plurality of streams, lanes for processing on a stream-by-stream basis are allocated in each of a transmitter and a receiver. With this, even if transmission of any stream is stopped, processing of a corresponding lane can be stopped. Therefore, it is possible to efficiently stop a bandwidth such that power saving can be realized. The present technology is applicable to a display port.
