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...

My journey in DATV and the future: 4K UHD or internet-linked DATV repeaters; Not that crazy? Draft In this post I want to briefly outline my DATV journey and a quest for Full HD DVB-T. I have achieved this in a relatively short time and out of some of my difficulties, have wondered if first, 4K UHD DATV and, second, network-linked DATV repeaters, are possibly not that distant. In this post I will outline my journey, as the future is path dependent, history matters! In the following two posts I will consider ways to achieve 4K UHD and internet-linked DATV repeaters. My DATV journey: Live Full HD DVB-T Personally, coming late to DATV at the beginning of 2013, with a 40 year break in my amateur radio activities (see my first post), I have not had to put in the extreme effort and expense of either analogue TV or digital TV, particularly over the last decade, such as by the DATV Express team, among many others. Before returning to amateur radio I had spent considerable time and...

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. The ATEM TV Studio is PC-based and is mounted in a small stand, just viable behind the...

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! Any frequency (up to 2.5 GHz!), any band-width, any media modulation parameter. There isn't anything that comes close, at any cost. I set it up on a channel my little 16" TV could receive (by cable with an attenuator) and connected...
