TR Number ARIB TR-B33
Technical Report Name Operational Guidelines for Terrestrial Mobile Multimedia Broadcasting by Transmission System Based on Connected Segments for VHF-High Band
General Description

This technical report specifies the operation of terrestrial multimedia broadcasting for mobile/handheld receivers with connected segments transmission system (hereinafter referred to as ISDB-Tmm) using frequency less than 222MHz and more than 207.5MHz,
