HDT-201 HDR-201

HD Uplink Transmitter/Receiver for Live Broadcasting

UDT-201 UDR-201

Digital transmitter for CATV uplink

The HDT-201 and the HDR-201 are a transmitter and a receiver for live HD/SD broadcasting with coaxial cable network.
The compact and light-weight devices integrate H.264 encoder and decoder in the chassis, featuring excellent mobility.

OFDM Modulation enabled the use at the frequency band where much noise exists. H.264 encoder and decoder are integrated in each compact body. Compact and light-weight body of the transmitter realized excellent mobility. Intercom devies are optionally avilable; Headset/2-wire/4-wire Bit rates and modulation systems can be programmed according to the C/N ratio of the field for best live broadcasting. The center output frequency can be programmed in the range from 13MHz to 52MHz in the resolution of 1MHz. The output level can be programmed in the range from +80dB to +110dB in the resolution of 2dB.
