800MHz-Band OFDM UHF Link
As digital TV broadcast technology has progressed, systems for transmitting digital program material have become increasingly important. In 1997, a technical standard for 800MHz-band OFDM UHF links was established at ARIB (Association of Radio Industry Businesses) and it is the first digital link that employs the OFDM modulation method. We have developed an 800MHz-band OFDM UHF link for digital transmission equipment. The specifications of the OFDM UHF link conform to the ARIB standard. The carrier modulated by the OFDM method transmits an MPEG-2 compressed 525-line video signal using an 800MHz-band wave. The OFDM UHF link was first used in live program production in June 1998, and it will become the key equipment for mobile transmission.
