4 Ch HDMI,YPbPr, CVBS to QAM, ASI & IP HD Encoder RF Modulator
QuestTel's HDMI QAM Modulators integrate high density hardware Mpeg2/H.264 encoder with QAM/ATSC modulator chassis system, which makes B-QAM-HDMI-IP-4CH the best solution for Live event broadcasting and professional Cable TV networking systems. Our HDMI to QAM core systems come with a big variety of features such as IPTV output and ASI mux, expanding amount of potential applications and adding flexibility to any pro AV system. Rack mountable enclosure allows you to stack many units together and with help of RF combiners generate your onw channel lineups, which will be fully configurable, since B-QAM-HDMI-IP-4CH provides major support for all advanced channel settings such as VCT (Virtual Channel Table) and LCN (Logical Channel Number). QuestTel's modulators already have been picked by well known companies not only because our high performance encoders ensure 100% uptime and stability of the system, but also because they come with advanced support for low latency configutation, which is critically important to all live broadcasting appications. B-QAM-HDMI-IP-4CH has all functions required by TV stations, including DD AC3 Audio and dedicated analog 608 CC port with RCA.
Nowadays one of the most desired features by all pro AV companies is an IPTV support, our engineers put a lot of effort and time to come up with supreme IPTV circut, which completes a full set of features of QuestTel's encoder modulator systems, allowing you to stream ip video over both UDP and RTP protocols (multicast and unicast). The unit comes with two IP ports, second one is used to provide web console interface for configuration and management, which could be accessed remotely via LAN.
A key feature of B-QAM-HDMI-IP-4CH is an outstanding choise of inputs, such as HDMI, Composite and Component video, ASI and SPDIF audio. Furthermore, QuestTel's modulator chassis provides full supports for all modern cable television standards - DVB-C, ATSC, DVB-T and ISDB-T. Overall QuestTel's encoder modulators perfectly suit any professional AV company, including TV Channes, Live broacasters, AV Installers and Integrators, Government applications and many others.
