A: Specifically, the CALM Act directs the Commission to establish rules that require TV stations, cable operators, satellite TV providers or other multichannel video program distributors (MVPDs) to apply the Advanced Television Systems Committee's (ATSC) A/85 Recommended Practice ("ATSC A/85 RP") to commercial advertisements they transmit to viewers.
