QMOD-SDI is an HDTV modulator that converts SDI, component or S-Video/Composite NTSC audio and video signals to a digital cable channel and amplifies them for distribution through a broadband cable system.
The Contemporary Research QMOD-SDI is an HDTV modulator that accepts SDI, Component, or S-Video/Composite NTSC inputs. It converts audio and video to a digital cable channel and amplifies it for distribution through broadband cable systems using existing coax cabling.
Users can configure the device via front-panel buttons and text menu displays. The manual details how to select input types (SDI, YPbPr, Video, S-Video), set resolution formats (1080i, 720p, 480i/480p), adjust RF output levels, and configure virtual channel settings for dual-part or single-part emulation.
