MUSE optimized for emission (i.e., broadcasting) rather than transmission (i.e., satellite distribution). It is a non-receiver-compatible, non-channel-compatible scheme occupying 8.1 MHz of base bandwidth and requiring four fields to build up a full-resolution picture. Thus, it requires motion compensation (and retains some motion artifacts). It offers four channels of high-quality digital audio. It has been tested in the Washington, DC area.
