MobaHO! was a mobile satellite digital audio/video broadcasting service in Japan, whose services began on 20 October 2004 and ended on March 31, 2009 at 15:00. MobaHO! used digital broadcasting specification of ISDB. The satellite, MBSat 1, providing this service is jointly owned by SK Telecom of Korea and Mobile Broadcasting Corporation (MBCO) of Japan.
This service used ISO MPEG-4 Version 1 Simple Profile @ L3 video and AAC audio encapsulated in MPEG transport stream. The maximum supported resolution was 320x240 pixels (QVGA), and the maximum video bitrate was 384 kbit/s at a frame rate of 15 frames per second. Audio conformed to the ISO/IEC 13818-7 AAC LC (Low Complexity) profile, with maximum bitrate of 144 kbit/s and sampling rates up to 48 kHz. The transmission was scrambled using the MULTI2 cipher for conditional access.
This service was broadcast over 2.6 GHz S-band by MBSat at 144.0°E. Left Circular polarized beam covered Japan, while Right Circular polarized beam covered South Korea. These beams were intended to be received by portable devices with omni-directional antennas. A single 150 W Ku band transponder on MBSat, operated at 12.226 GHz and Symbol rate of 18433 was used to broadcast identical contents to "Gap-fillers" (re-transmission devices) which were planned to be installed in train stations and subways, and other areas where the S-band satellite beam would not reach. This repeater broadcast was also scrambled using MULTI2.
The company had expected to attract a million subscribers by 2008, but had only reached about a hundred thousand. They ceased operations on March 31, 2009.
