Toward the closedown of terrestrial analogue TV broadcast on 24th July 2011, the construction of the terrestrial digital broadcasting relay stations is becoming the final stage, and it is still necessary for its costs to reduce further. As for mini-transmitting system, we are promoting the low-cost type using a gap filler system. However, there are many mini-transmitting stations that should keep frequency precision to avoid SFN interference between the other stations. So, we could not adopt conventional gap filler system, because it has only a crystal oscillator or an OCXO oscillator. Therefore we developed a gap filler system to report here, which can input 10MHz signal from an outside standard oscillator.
