COFDM kaiwhiwhi ahokore tawhiti roa tawhiti tuku me te Real – pūnaha tuku wā

COFDM kaiwhiwhi ahokore

kaiwhiwhi ahokore COFDM ki tawhiti roa te tuku tawhiti

 

 

painga pūnaha

 

1. tawhiti te tuku tawhiti roa

2. pūnaha tuku-wā Real

3. Ko te tino poto iti iho i te 500ms te wā roa

4. kounga image Perfect, tae kanapa me te whakapakoko whakaene

 

āhuatanga

 

1. Tuku 1W mana

2. Tino Kōmāmā me te whare tiketike

3. wiri, resistance pānga

4. Taupānga o COFDM puoro, MPEG-2 / H.264 kōpeketanga

5. rahi iti, 102 × anake 60 × 21.5 mm

6. Perfect tono pūkoro

7. tuku Video o te kounga teitei, kahore mosaic, kahore āhuatanga tō

8. Tautoko rārangi-kore-o-titiro tuku, āheinga ttara kaha;
