Catv multi channel rf isdb-t modulator 16 carrier out for Digital Cable TV System with 3*GbE Port input
Q4 IP to RF modulator, with ASI input, optional modulation (DVB-C, DVB-T, ATSC, ISDB-T, DTMB) to convert Video/Audio signals into RF over exist Coax Cable distribution. It provides a best-of-class modulator platform for Digital TV Owners and IPTV operators.
The platform can change the modulation signal by software upgrade, this flexible operation can help to reduce the cost in the operation of the project. Q4 supports modulation channel independent multiplexing, with DVB-T, ISDB-T, DVB-C, ATSC, DTMB modulation output, and can output different modulation signals.
- High density, high quality, high performance, high flexibility
- Optional DVB-C (QAM), DVB-T (COFDM), ATSC-T, ISDB-T, DTMB Modulation, 8/16*Carrier RF Out
- supports 384*IP (SPTS/MPTS) inputs over 3*GbE Port
- 6 separate ASI input
- 8*MPTS (6*MPTS and 2*RF pass through) out over GE1
- 8/16 Channel Non-adjacent Carrier RF output
- Supports non-adjacent frequencies in the whole frequency range, and solves a small number of isolated frequency points
- Agile full-band: 96 ~ 864Mhz
- Selectable the Value of PCR PID same as Video PID
- LCN (Logical Channel Number) support
- PSI/SI editing & inserting
- PID Remapping & Filtering
- Support TTL editing
- PCR correct and PCR interval adjusting
- Superior Shoulders and Excellent modulation quality MER
- Easy-to-Use System Management via Web
