2.1 - Description
The HDMOD-Q1 is a high quality quad DVB-T "Home" modulator which accepts four HDMI inputs and converts
them into four RF DVB-T channels on its output. The excellent picture (Full HD 1920*1080-30p) and modulation
quality (MER~35dB) renders the HDMOD-Q1 the ideal solution for distributing SD/HD digital signals coming from
e.g. a DVD player, STB or camera in a CATV network using the DVB-T technology.
The user has the ability to control the device by either using the onboard SSD (Seven Segment Display) interface
and keypad for quick installation or by using the USB interface with the appropriate software accompanying
the HDMOD-Q1 for advance programming.
Finally, the HDMOD-Q1’s metal case provides excellent electromagnetic shielding as well as great temperature
dissipation and rigidness.
