This letter proposes a practical source coding scheme, so-called hybrid majority voting (HMV) code, for lossy compression with a discrete memoryless source. Inspired by the coding scheme used in the classic rate-distortion theorem, we find a series of basic MV codes and analyze their rate-distortion performance. We then present an algorithm to find two component MV codes and apply them to lossy compression, group by group, to construct HMV codes. Finally, we show an example of joint source-channel coding based on the HMV code. The performance evaluation indicates that the HMV code makes it possible to easily control efficiency and complexity.
