As a move to new headquarters, Video/Audio signal distribution system and Remote micro wave (for field pick up) relation system was renovated. With an eye to the future, we made a decision to employ a total component digital format. The multiplexed optical format can send all input signals to destination via one optical fiber. According to this renovation of both systems, we set up "Remote Center" where we can organize remote micro wave line and can observe and can control in our new headquarters.
