Abstract
The present disclosure relates to a signal transmission device, a signal transmission method, and a program that are capable of reducing the influence of a quantization error. A quantization error notification unit notifies the stage after a bit precision constraint region of a quantization error generated in a quantization processing unit that performs a quantization process on a signal to be transmitted via the bit precision constraint region that is a region where a bit precision constraint occurs. A quantization error reception unit receives the quantization error, and supplies the quantization error to an inverse quantization processing unit that performs an inverse quantization process on the signal transmitted via the bit precision constraint region. The present technology can be applied to an image signal transmission device that transmits image signals, for example.
