DVB-T Digital Gap Filler/Repeater

Name: BR-100E DVB-T Digital Gap Filler/Repeater
Brand: HiDes Technology
SKU: BR-100E

Hardware demodulate-and-remodulate TV signal repeater

50–950 MHz and 1200–1350 MHz

BR-100 is a hardware digital TV gap filler/repeater: the received TV RF signal is demodulated to a transport stream and re-modulated to a new TV RF signal entirely in hardware, without any MER loss or added noise. With built-in 31-way PID filters and PCR re-stamp, infinite digital TV signal extension can be achieved with BR-100.

DVB-T (EN 300-744) · Tx 50–950 MHz and 1200–1350 MHz · Bandwidth 2/3/4/5/6/7/8 MHz

Features

01 Features — Hardware modulator and demodulator support EN 300-744 DVB-T /ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb reception and retransmission. TV RF signal is demodulated to a transport stream (TS), and then modulated to a new TV RF signal with fully hardware digital processing without any MER loss or any noise addition. Built-in 31-way PID filters and PCR re-stamp.
02 BR-100E supports EN 300-744 DVB-T while BR-100J supports ARIB STD-B31 ISDB-T/ABNT NBR 15601 ISDB-Tb.
03 BR-100EH is a special edition of BR-100E for HAM TV application; BR-100EH can support up to 1.2G band with high RF power (-18dBm), but 2'nd and 3'rd harmonic in 950MH~1350MHz band is not well filtered.
04 Demodulator (Receiver) — BR-100E supports Digital Terrestrial DVB-T Receptions (5/6/7/8 MHz bandwidth) and amateur HAM DVB-T TV reception (2/3/4 MHz bandwidth). BR-100J supports Digital Terrestrial ISDB-T/ISDB-Tb Receptions (6/7 MHz bandwidth).
05 Modulator (Transmitter) — Direct digital conversion to 50~950MHz and 1200~1350 MHz for excellent signal quality.
06 BR-100E supports configurable bandwidth from 2MHz to 8 MHz. BR-100J supports configurable bandwidth 6/7/8 MHz.
07 Channel Adaptation — The input and out channels are totally independent. The new (Tx) channel's frequency, bandwidth, code rate, guard interval, FFT, constellation can be totally different from the original (Rx) one's. If the input channel data rate is less than the output, auto null-packet insertion will be done in the modulator. If the input channel data rate is larger, setting PID filter properly to filter out unwanted packets may avoid data overflow. PCR re-stamp mechanism is supported to keep the correctness of PCR when PID's filtered or null packets inserted.
08 Applications — DVB-T/ISDB-T digital TV signal repeater/extender · DVB-T/ISDB-T closed circuit TV gap filler · Air to Cable/Cable to Air/Air to Air/Cable to Cable TV signal repeater

1 : Bandwidth 2/3/4 MHz or 5/6/7/8 MHz are selected by a jumper.
2 : The U-band low pass filter is designed @950MHz, so 1.2G band power is filtered to such a low level.
3 : There could be MER loss in high gain/attenuation level.
