JF640-6 is a headend equipment with the professional broadcasting
quality according to DVB standard . Its main function is to
directly convert signals which could be QPSK modulated from
satellite or other program source to TS stream and remultiplex with
ASI signal locally and then transmit via HFC or MMDS networks after
QAM modulation. It needn’t decompress, compress, QAM modulate, but
directly modulate data stream demodulated to QAM signal sending to
HFC or MMDS network. Therefore, it carries out SDTV/HDTV services
and so on, providing many digital TV programs and data broadcasting
programs with low-cost in SMATV. It is used widely in various
digital brodadband systems such as digital TV, data broadcast, VOD,
Internet and video conference etc. Features input interface ：ASI and digital satellite ASI and QPSK loop output interface ASI interface input data rate(per channel): 216Mbps(max) Remultiplex 2 channels TS PID filtering and reset, users add and delete programs at will,
auto-mapping PID of program selected. Support user-defined PID and
input bypass. Support ITU-T J.83A and B FEC up to DVB-C Work at mode 16QAM、32QAM、64QAM、128QAM、256QAM Input RF（QPSK） frequency：950MHz-2150MHz Input RF BW：6MHz、7MHz、8MHz Input data(ASI interface) bit rate:1.5～51.6Mbps Output data bit rate:2～56Mbps Output signals BW：1.15～8.05MHz(the Fall is 0.15) Output data symbol ratio：1～7Mbaud/s Output RF frequency：48～860MHz Output level：100dBuV～115dBuV(stepping available) 188 and 204 packet auto-identify, displaying input data format real
time. Large cache, ASI interface support input burst and average bit
stream, reforming bit stream average in order to promote the output
bit stream efficiency. NIT mapping and sending, support 44 NIT mapping 10 groups PID filtering and re-mapping Outstanding self-adapting filtering circuit designs to maximal
reliability and availability. Various PSI/SI information tables pick-up, parse and modification
(customization available). SI information replacement and insertion Input data null packet filtering and output data stuffing PCR correction function can correct various input data,
respectively and accurately Show and inspect system input bit rate and valid bit rate real-time -20dB RF testing interface with IF output Error alarming LCD display Network interface introduces remote maintenance, supervision and
