Thor SDI Modulator is the Hybrid to choose. This is the most versatile SDI & HDMI unit form Thor


This unit provides up to 8 SDI or HDMI inputs you can select either in the options menu or on the simple and creative GUI. This Thor modulator has independent input cards for flexibility for Digital Modulation because it eliminates the need for SDI to HDMI or HDMI to SDI  converters. Simply select which source you want to use and input the channel frequency creating an automated encoding headend device that can clean up your headend and modulation distribution infrastructure.


Each channel can individually be selected as an SDI or HDMI input, it could be switched on the fly using front panel buttons or Thor’s dynamic proprietary Web interface. Each of the 8 channels of RF output can be set totally independent as a frequency AND modulation standard. For example, you can input 4 channels of SDI and set to ATSC output and then input 4 channels of HDMI and set to QAM. This is a flexibility that hasn’t been seen before on the market creating a whole new generation of standard for encoder modulation products.


The New THOR HYBRID Modulator has an NMS port and LCD display with simple D-Pad buttons for control and easy setup on the fly. It includes and supports the majority of Modulation standards found in the world; like Clear QAM Annex A and Annex B, ATSC-8VSB, DVB-T, and ISDB-T. The Hybrid modulator support MPEG2 video encoding up to 25Mbps/channel, Audio AC3 or MPEG1 Layer 2, and AAC, Thor’s world-famous Low Latency, and VCT -Virtual Channel Numbers for increased flexibility. Each CATV RF channel can be set individually, so it does not have to be in a linear 8ch block, feel free to spread out your new custom RF channels all over the existing RF spectrum in your modulation lineup.
