FMUSER DTV-4405T-16/24 is a high-performance and cost-effective DVB-T modulator. The device is designed to support up to 24 or 16 FTA tuners input; with a maximum of 256 IP inputs through GE1&GE2 and TS input for re-mux through 1 ASI port. The device is equipped with BISS descrambling (only for FMUSER DTV-4405T-16/24-B); multiplexing; and DVB-T modulating functions; which allow it to give 8 non-adjacent carrier output and 8 IP (MPTS) output as a mirror of carriers through GE1.
The FMUSER DTV-4405C-16/24 is a Mux-scrambling QAM modulator. The device is designed to support up to 24 or 16 DVB-S2 FTA tuner input; with a maximum of 128 IP inputs through GE1 and TS input for re-mux through ASI ports. After multiplexing; scrambling; and QAM modulating; it gives 16 non-adjacent carrier output and 16 IP (MPTS) output through GE2. The DTV-4405C-16/24 is highly integrated; high-performing; and cost-effective; making it an ideal solution for newly generation CATV broadcasting systems. Also suitable Cable digital TV adjacent frequency front-end system; hotel IPTV network TV system and hotel satellite digital TV system.
24 DVB-S2 FTA Tuner + 1 ASI input + 128/256 IP input thru GE1 over UDP and RTP protocol
16*DVB-C/8*DVB-T RF output
16 groups multiplexing + 16 groups scrambling + 16 groups QAM modulatingIt
Supports dual power supply; which is optional; making it very adaptable to newly-generation CATV broadcasting systems.
The modulator offers 16 non-adjacent carriers output and 16/8 IP (MPTS) output through GE2 after multiplexing; scrambling; and QAM modulating.
The RF output performance index is excellent; with MER≥40db; ensuring high-quality output for broadcasting.
Accurate PCR adjustingAccurate PCR adjusting; which helps to maintain the integrity of the digital signal during transmission.
Additionally; it supports PSI/SI editing and inserting; which allows broadcasters to customize their digital broadcasts with relevant information such as program guides and channel information.
Support A/V PID filtering; A/V PID filtering is a process used in digital video broadcasting systems to filter out specific audio and video streams from a transport stream. A transport stream is a digital data stream that contains multiple audio; video; and data streams multiplexed together. PID stands for Packet Identifier; which is a unique identifier assigned to each audio; video; or data stream within the transport stream. A/V PID filtering allows broadcasters to select and extract specific audio and video streams from a transport stream; which is useful when broadcasting only certain programs or channels. It involves selecting the desired PIDs for audio and video streams and discarding the rest of the data to reduce bandwidth and improve the quality of the transmitted signal. A/V PID filtering can be performed using specialized equipment such as digital video receivers; modulators; or set-top boxes. It is an essential process for delivering high-quality audio and video content in digital broadcasting systems.
Controlled via web management; with easy updates via web; allowing users to configure the device to meet their specific requirements quickly and easily.
In conclusion; DTV-4405T/C-16/24 is a cost-effective solution for CATV broadcasting systems that offers excellent performance and versatility. Its support for accurate PCR adjusting; PSI/SI editing and inserting; and web management make it a reliable and popular choice for broadcasting systems. With its high integration level and excellent RF output performance index; it is a versatile and reliable choice for those looking for a QAM or DVB-T modulator.
