The DVR specification is designed to work in concert with A3SA’s earlier established Broadcaster Encoding Rules, which govern how broadcasters can use the A3SA security technology with ATSC 3.0 content that is simulcast with corresponding ATSC 1.0 content, allowing viewers to decode and record broadcasts, make unlimited copies without expiration dates, and use common features like pause, rewind and fast-forward. The A3SA Encoding Rules also prevent downgrading of picture quality when connecting to legacy television sets.
