Abstract
In this paper, we proposed a polyphase encoder that consists of multiple internal encoders. The multiple internal encoders were configured in parallel. Successive frames of image were distributed to separate encoders by way of a image divider and processed in parallel. In this way, the sampling rate of the encoder was reduced by the factor of number of encoders in parallel. In our design, however, the PSNR is exactly the same as that to be achieved with the conventional single-phase encoder, which should require a much higher sampling rate.
