Command Audio's patents cover the audio elements of devices and services that enable users to receive programming via broadcast transmission and store it for playback at a convenient time.
Since audio is a critical dimension of both radio and television programming, these patents have far-reaching coverage. Personal video recorders (PVRs, also referred to as digital video recorders, or DVRs), advanced radios with recording capability, personal computers and cell phones capable of receiving content via broadcast means and storing it for later playback, as well as the services that transmit content to all of these devices, use Command Audio technology.
