ATSC 3.0 is on the home stretch as it becomes deployed in the U.S.A. and Korea. ATSC 3.0 architecture is radically different from ATSC 1.0. It relies on the very latest codecs and architectures that bring together IP, audio, and RF infrastructures (including MTP) that offer more flexibility for users who are used to IP standards like DASH, and offers more choices about content when watching TV at home or in the field. At the same time, ATSC 3.0 provides emergency alerts (AWARN) so that we can be informed about impending natural disasters in the making. ATSC 3.0 adopted HEVC (H.265) as its underlying codec since it offers nearly four times the compression of MPEG-2 and thus there is more capacity for more programs. This makes broadcasters happy. A new audio compression standard is also available that offers numerous audio options from immersive audio to special commentary. Even though the Cortina was specifically designed for ATSC 3.0 applications, it is also suitable for most traditional HEVC compression tasks since it outputs traditional TS as well as MTP. It creates amazing 4K or multiple 1K HDR content. The Cortina is a hybrid HEVC encoder designed to be compliant with A/300 System, A/331 Signaling-Delivery-Sync-FEC, A/341 Video-HEVC, and A/342 Audio standards which are all in Candidate, Proposed, or Finalized Standards stage. It has been validated in ATSC 3.0 signal chains in Korea and the U.S.A.
