Soalan Lazim
Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: Ya. The 1907 menyokong MPEG-2 video encoding, required by Japan’s ISDB-T system, dan 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?
A: Ya. Dengan 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?
A: Tidak. 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?
A: Hingga 72 saluran using DIP switch configuration.
Q: Adakah anda mempunyai input SDI ISDB-T Output 6M Encoder/Modulator?
Hi, Kami ingin membeli beberapa encoder/modulator ISDB-T untuk Argentina (6MHz), Mungkin saluran VHF atau UHF. Sekiranya kita boleh memilih, Kami lebih suka input video HD-SDI.
Jawapan: Ya, Sila periksa model di bawah.
