HiDes HV-202E DVB-T self-contained transmitter: Quality all digital live DATV from DSLR camera at last! The HiDes HV-102E DVB-T self-contained transmitter has arrived at US$660 delivered. I ordered the USB version of this professional HDMI/HD-SDI 4 band (100 MHz - 2.5GHz) DVB-T TX originally, but upgraded to the stand-alone box instead. (see why latter). It works perfectly out of the box and is easily configurable for any modulation or media parameters. I had a good experience with the HiDes DVB-T HD CCTV camera transmitter; see earlier post. As such I thought I would try their HDMI input DVB-T TX. Surprising similar, as will be explained. The impressive specifications per HiDes: There isn't much this box can't do!

The DC-100 transmits both a SD and HD channels as can be seen in the channel list. The camera is running on its default setting of 177 MHz, 6 MHz bandwidth, but over a cable with an attenuator. The image is 1080P 30 FPS. As a result there is some flicker from the 50 Hz lights. I will put up some photos of the device and its internals later. CCHDTV is an emerging standard of DVB-T cameras designed to run on existing coaxial systems in buildings and institutions. The devices all seem to be based on the ITE modulator chips. Google CCHDTV for more information. The DC-100 uses a standard CCTV SDI camera, either 2 or 5 Megapixel, the converts the raw S...
