GDM-023 数字调制器

CM-1050
The Channel Master ATSC HD Modulator is a professional-grade encoder/modulator designed for commercial and residential installations. The ATSC HD Modulator converts a video signal from HDMI format to a digital channel (ATSC) format. The digital channel can then be output via the coaxial RF output on the back of the device. The digital channel number (Channels 1-99) is user selectable. Digital channels that are generated from this device can be scanned and tuned by most TV and set-top box ATSC/OTA tuners. Equipped with a front panel display and menu navigation buttons, settings such as RF channel number, virtual channel number and RF output level can be configured without the use of a computer. The modulator can also be managed over a local network via the built-in ethernet port.
