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.

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.

DSLR cameras are very popular with cinematographers, with an ability to do Full-HD and even up to 4K resolution (4K is used by cinema projectors). See sources such as  http://nofilmschool.com/  Digital Filmmaker magazine For DVB-T the maximum resolution is Full HD 1080i at 24, 25, 30, 50 or 60 fps (frames per second), and more commonly 720p at the same frame rates. The frame rates are related to the frequency of the electricity supply in the country, 50 Hz in Britain and Australia, 60 Hz in Northern ...
