FAQ
Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
UNE: Oui. le 1907 les soutiens MPEG-2 video encoding, required by Japan’s ISDB-T system, et H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.
Q: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
UNE: Oui. Avec 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.
Q: Can it be used in DVB-T systems?
UNE: Non. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.
Q: How many channels can I set?
UNE: Jusqu'à 72 filières using DIP switch configuration.
Q: Avez-vous une entrée SDI, une sortie ISDB-T, un encodeur/modulateur 6M?
salut, nous cherchons à acheter un encodeur/modulateur ISDB-T pour l'Argentine (6mhz), Peut-être des canaux VHF ou UHF. Si nous pouvons choisir, nous préférons l'entrée vidéo HD-SDI.
Répondre: Oui, veuillez vérifier le modèle ci-dessous.
