Key Features

HV-122 is a 1080 Full HD diversity receiverbox which receives and decodes DVB-T (ETSI EN 300 744) HD/SD terrestrialbroadcast signals. It features the video output of HDMI and Composite (CVBS)for DVB-T.


HV-122 is designed with 2-way diversityantenna reception, which can enhance high mobility support and mitigatemulti-path effect.


Besides remote controller, HV-122 can beconfigured and controlled thru its UART port by an external host.


HV-122 can decode the mux’ed UART data inreceived streams and output thru its local UART port.


Besides standard TV channel bandwidth (5/6/7/8MHz), HV-122can tune 1/1.5/2/2.5/3/4 MHz bandwidth channels.


Depending on the model options, HV-122 supports standardTV-band (170-860MHz), 2.4G-band (2100~2550MHz), All-band (170~2700MHz)

l  *There is a saw filter in the RF front end. The saw filter limits the reception range but minimize ACI (adjacent channel interference)

l  **When the saw filter removed, full band range is supported but poorer ACI. The sensitivity is ~20dB less at 170~700MHz.
