ʻO ka transmitter COFDM-907T kahi mea hoʻoili ʻikepili wikiwiki wikiwiki no nā polokalamu wikiō a me nā leo hoʻoili leo kiʻekiʻe. Ma waho aʻe o ke koi wikiō kiʻekiʻe a me nā koi leo o ke kāmela, ka hoʻopā'ālua kahawai, a he kiʻekiʻe loa ka pono o ke kahawai. Ua hiki ke hoʻouna i H.264 kiʻekiʻe-kbps codec, he hoʻonā kiʻi hoʻokipa a hiki i 1920X1080P/60.
