BlackMagic Design ATEM TV Studio problems with 1080p; a hardware limitation? In this post, I think I have discovered the problem of the ATEM TV Studio not accepting 1080p input, a hardware limitation. Alternatives are then considered. BlackMagic Design ATEM TV Studio As noted in earlier posts, I use BlackMagic Design ATEM TV Studio as the main component of my DATV studio to connect multiple cameras and other video sources. Overall it performs brilliantly well allowing for most features needed in a professional TV switcher, and with nothing else even remotely in the price range; $1000. http://vk4zxi.blogspot.com.au/2014/06/datv-dvb-t-blackmagic-designs-atem-tv.html     No 1080p input, despite being common format for cameras However, it has one very annoying problem, it will only accept 1080i input, not 1080p, which to a point is reasonable as 1080i is the highest resolution for broadcast TV. The big problem is that almost all cameras...

HD DVB-T HiDes HV-202E ATEM TV Studio DVB-T DATV all working Finally, I have all the pieces connected for a high-quality, live DVB-T TV studio and TX. My interest has been in establishing a high quality, video and audio, DATV system. This post covers the full working system, albeit small-signal. The details of each of the components are covered in earlier posts. The main components of the system are: HiDes HV-202E, self contained DVB-T TX with HDMI input: http://vk4zxi.blogspot.com.au/2014/07/hides-hv-202e-dvb-t-self-contained.html BlackMagic Designs ATEM TV Studio: http://vk4zxi.blogspot.com.au/2014/06/datv-dvb-t-blackmagic-designs-atem-tv.html High-definition digital SLR and CCTV video cameras: http://vk4zxi.blogspot.com.au/2014/06/dslr-cameras-for-live-tv-not-so-simple.html , http://vk4zxi.blogspot.com.au/2014/06/hd-cctv-cameras-cheap-quality-live.html The front of the operator console.

DSLR cameras for live TV: not so simple! In the course of setting up an amateur radio DVB-T transmitter, I have sought high quality video and audio. The modern DLSR (digital, single lens reflex) cameras seem to be a good candidate as they are capable of recording very high quality video, have a wide range of relatively inexpensive lenses and have some auto-focus capability for use by a one-person camera operator. They are generally better than consumer-grade camcorders. 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 ...
