This technology pertains to a transmission device, a transmission method, a reception device, and a reception method that make it possible to improve transmission efficiency. An encoded signal is generated on the basis of real-time data, which is represented by waveform L, using a prescribed fixed bit rate as the maximum encoded size (Sx). If the encoded size of the generated encoded signal is less than said maximum encoded size (Sx), an amount of non-real-time data corresponding to the shortfall, as represented by region Z12, is inserted into the encoded signal, and the resulting encoded signal is transmitted at the aforementioned fixed bit rate. This technology can be applied to broadcast communications. |
