Engineered with full-band agile RF frequency synthesis across 47 to 862 MHz (expandable to 1000 MHz), SOUKA digital modulators support software-switchable broadcast standards—including DVB-T (COFDM), ATSC 8VSB, DVB-C (Clear QAM J.83A/B/C), ISDB-T, and DTMB. Featuring advanced surface acoustic filtering and low phase noise circuitry, the hardware achieves an exceptional MER (Modulation Error Ratio) ≥ 40 dB with 70 to 105 dBµV adjustable RF output, delivering crystal-clear 1080P/4K video over legacy 75-ohm coaxial lines (RG6/RG11) without snow, ghosting, or interference.
Integrated with dedicated ASIC/FPGA hardware compression engines, SOUKA encoder modulators process multi-channel HDMI (HDCP decryption compliant) and HD-SDI video inputs in real time via H.264 (AVC) and H.265 (HEVC) with ultra-low transmission latency (<200ms). By converting video feeds directly into standardized digital RF television channels, commercial displays tune in directly via their built-in digital tuners—completely eliminating external set-top boxes (Zero STB) and slashing hardware procurement CapEx and remote-control maintenance by over 50%.
Designed for professional headends, SOUKA delivers scalable form factors from compact tabletop units to high-density 1U rackmount chassis (4, 8, 16, or 24 HDMI-to-RF channels) and modular 4U chassis with redundant hot-swappable power supplies. Engineers can configure Logical Channel Numbering (LCN), virtual channel tables (PSIP/VCT), and custom channel names either locally via the front-panel LCD screen and navigation buttons or remotely via an embedded Web GUI and SNMP network management console.

An IPTV encoder converts a video source into a compressed stream that compatible receivers can play over an IP network. For a hotel or commercial building, the right choice depends on much more than resolution: source interfaces, audio support, simultaneous encoding capacity, delivery protocols and endpoint compatibility must work together. This buying guide helps system […]

An IPTV server quotation can look straightforward: a rackmount unit, a channel allowance, and a maximum number of users. Yet those three items do not tell a hotel operator or system integrator whether the proposed platform will handle the actual service. Live television distribution, interactive menus, video-on-demand, device management, and video conversion place different demands […]
