よくある質問
Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
あ: はい. の 1907 サポートします MPEG-2 video encoding, required by Japan’s ISDB-T system, そして 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?
あ: はい. と 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?
あ: いいえ. 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?
あ: まで 72 チャンネル using DIP switch configuration.
Q: Do you have an SDI input ISDB-T output 6M encoder/modulator?
こんにちは, we are looking to buy some encoder/modulator ISDB-T for Argentina (6mhz), Maybe VHF or UHF channels. If we can choose, we prefer HD-SDI video input.
答え: はい, please check the below model.
