Kansai TV demos UltraHD broadcast over ISDB-T

Weeks before the first 4KTV World Cup, leading Osaka commercial broadcaster Kansai TV has demonstrated an UltraHD TV terrestrial broadcast delivery service over ISDB-T.
Kansai Telecasting Corporation is the leading commercial broadcast television station in Osaka and serves the Kansai region of Japan. Affiliated with the Fuji Network System, Kansai Telecasting Corporation caters to both local and nationwide audiences, providing drama, sports, news, documentary and variety programmes, as well as live entertainment, mobile content and feature film production.

During the 4K demonstration, original Kansai TV content featuring the 2014 Osaka International Women's Marathon was transmitted by very low power from an indoor UHF antenna with 64QAM modulation to a receiving antenna licensed for the demonstration.
To enable its service Kansai TV turned to Elemental Technologies to provide video processing technology encode 4K content in high efficiency video coding (HEVC). Elemental encoded the content in 4K/HEVC at full frame rates for transmission at 14.5Mbps over ISDB-T to a decoder for display on a Toshiba Regza UltraHD TV. The ISDB-T broadcast standard is claimed to drive efficiencies by enabling terrestrial TV and mobile terminal broadcasts over a single transmitter – in contrast to other standards, such as DVB-T2 which requires two transmitters. Japan, the Philippines, Costa Rica and multiple South American countries, crucially Brazil, are among the regions that have adopted ISDB-T.
