The present disclosure relates to a signal transmission device, a signal transmission method, a signal reception device, a signal reception method, and a program capable of multiplexing an audio signal of a larger number of channels. Provided is a signal transmission device including a multiplexing unit that converts data of at least one frame of a MADI signal conforming to the MADI standard into an ancillary data format and multiplexes the data as words transmittable within a horizontal blanking period of a video signal conforming to a predetermined standard. The present disclosure can be applied to, for example, an imaging device such as a camera.
