This standard specifies transmission system for advanced wide band digital satellite broadcasting, and describes about operational guidelines for PCR and site diversity, the result of experiments for transmission by satellite, circuit design, etc. in detail. On standardization, this standard was provided as a private standard considering international development in the future.

Also, 16 APSK and 32APSK (Amplitude and Phase Shift Keying) are noted as “system that will be applicable by the progress of related technology in the future” in the report of Information and Communication Council “Technical condition concerning advancement of digital satellite broadcasting” (29 July 2008), and Ordinance and Notification do not specify them. But as they are the transmission systems with big capacity which can handle the increase of transmission capacity for high quality video of broadcasting in the future, this standard specifies about 16APSK and 32APSK in order to stimulate to develop related technology for practical use. Also, practical operations are limited within the scope of Ordinance and Notification.
