The Act directed the NTIA to implement and administer a program through which eligible US households could obtain a maximum of two "coupons" (actually payment vouchers) of $40 each, to be applied towards the purchase of a digital-to-analog converter box. The Act defines the term "converter box" to mean "a stand-alone device that does not contain features or functions except those necessary to enable a consumer to convert any channel broadcast in the digital television service into a format that the consumer can display on television receivers designed to receive and display signals only in the analog television service, but may also include a remote control device." The Act, however, did not define "eligible household".
