mobile broadcast satellite (Japan) (MBSAT)

Mobile Broadcast Satellite (MBSAT) is a broadcast satellite service used in Japan to carry digital broadcasting, video and other multimedia services for mobile devices.

MBSAT uses MPEG-2 Advanced Audio Coding( AAC) for audio compression and MPEG-4 for video compression, and transports the information in an MPEG-2 container. The MBSAT system can support over 50 channels simultaneously.

Satellite transmission takes place in the downlink in the S-band between 2.630 GHz and 2.655 GHz. To eliminate transmission gaps within densely populated cities, the MBSAT concept provides for terrestrial transmission wherever satellite reception is not possible. The MBSAT satellite system has 16 transponders, all operating on the same frequency with code division multiplexing( CDM).
