Satellite bandwidth to planes, trains, (and automobiles? or maybe ships) is super expensive. Codecs like AV1 and HEVC can provide real financial benefit for satellite transport of live TV. It can be challenging, however, to deliver state-of-the-art when, at the far end, you must ultimately provide service to devices which aren’t part of your closed system (e.g., customer phones, tablets, laptops and/or embedded screens which may be years or decades old). Edge transcoding (e.g., on a plane) may not win you any video quality awards, but it can significantly lower operating costs and put your technology roadmap back in your own control. At Gogo, we multicast live TV using HEVC over our satellite network. On-board each plane, we transcode 12+ channels to h.264, MPEG2 (and pass-through HEVC) to provide compatibility with every variant of embedded and end-user devices. All of this is done using ffmpeg + vaapi. When AV1 comes of age, we can migrate to AV1 from HEVC without worry of breaking compatibility with existing customer and embedded devices.
