HD DVB-T HiDes HV-202E ATEM TV Studio DVB-T DATV all working

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:

The front of the operator console. The ATEM TV Studio is PC-based and is mounted in a small stand, just viable behind the laptop screen. The ATEM uses up to eight live video and recorded video sources via HDMI or HD-SDI. The recorded video is via a WD TV Live network media player via HDMI (white dot behind remotes), streaming content via network from main media server. The system is connected direct to a TV via an attenuator, hence the media. The stand is made from square section aluminium, plastic joiners and plywood, making the system semi-portable. The source screen for the ATEM is a cheap 16" TV with HDMI input is attached via VESA mount. I intend to add a very small monitoring screen of the final transmitted signal, just to check for gremlins.


 
The back view shows the components more clearly. The ATEM TV Studio and the WD TV Live are network devices, connected via a switch or router/switch. Only the HD-CCTV camera is being used in this shot. The DSLRs connect via HDMI. The HV-202E is bottom right, with its lid off. The whole thing is on our camping table in the spare lounge; very tolerant of my wife.

 
 
What a rats' nest of cables and wall-warts! Everything runs on 12V so I may use one power supply and individual switching.
 
 
 The final product, a view outside the lounge window. Trivia: The 240V socket used in Australia is only used in New Zealand and apparently China, but originally patented in the USA in 1922.
 
 
The on-screen info is just to show sources.
 
So, a basic, semi-professional TV studio and modulator/TX for around $2000. ATEM TV Studio ~$1000, a bit expensive but much better than HDMI capture cards. HV-202E 4-Band professional DVB-T modulator/TX ~$660, again a lot simpler than USB devices. HD-CCTV cameras ~$130 each plus lenses, but even good ones are cheap. Audio deck and microphones, not shown, but starting around $200. DSLR cameras can be used, but they start to blow the budget, however, a Canon M series running Magic Lantern firmware for a clean HDMI video feed ~$350.
 
To go on-air, a Darko 70cm 10W amplifier (~200 Euro) and possibly a pre-amp (~$100) then cabling, antenna etc. As per any DATV DVB-T system.
 
As a footnote, the system originally was set to use H.264, but the six year old TV couldn't decode it. Setting the system back to MPEG2 fixed the problem. The newer TV in our main lounge could receive H.264.

  1. Being able to custom build a station like that is really cool. I find ti nice that I can go to a store and ask for advice about building something. After getting the advice I can usually buy the pieces I need. Though sometimes people forget that they are speaking in terms that not everyone understands. My dad used to and still does that.
