Abstract :
A multimedia broadcasting service for mobile receivers based on the ISDB-Tmm standards using spectrum from 207.5MHz to 222MHz after the shutdown of analog TV service will be launched in spring 2012 in Japan. The ISDB-Tmm is a broadcast technology based on ISDB-T, which is used for digital terrestrial TV services and has superior transmission characteristics in mobile environments. The ISDB-Tmm has various enhanced functionalities for the new multimedia broadcasting services, such as high quality video and audio coding, advanced inter-media inter-link, and efficient file download over broadcast channels.
