The secret to sending analogue video signals over UTP is to balance them well. Video balun is a device made for this. I earlier write about Video over UTP and my own experiments related to it. Here is a look wat what is inside a commercially made inexpensive video balun, in this case LLT-201 from →
Traditionally analogue video transmission is done using 75 ohm coaxial cables. Those video signals are not directly compatible with nowadays more widely used twisted pair wiring (CAT5, CAT6 etc..), which means you just can’t wire the signals directly form video output to a twisted pair wire. The mains problems in connecting 75 ohms video source →
I have searched for some time a suitable software (preferably free) that allows me to measure Bode plot of electronics circuits. There are commercial software, special hardware and special instruments for that (network analyzer can usually do that on radio frequencies), but I wanted something that uses the hardware I already has. After some searching →
I just noticed that MIDI turned 30 years ago just a short time ago. This 31.25kbd 10-bit, 16-channel network is still very much in use today, 30 years after its official 1.0 specification release in August 1983. I forgot to say “Happy Birthday MIDI” at the right day. The Register had an article series on →
Earlier I have written how I configured my Raspberry Pi configured for media playback. Then on comments I write how XBMC-Elisa-Viihde-plugin started to fail and I could not solve the issues (normal update, plugin uninstall/install and even full reinstall did not work). Now I finally have success with my Raspberry Pi media player. Reinstalling the →
I have written earlier about USB and Ethernet audio. Audio networking offers key benefits, like a dramatically reduced cable infrastructure, easy audio signal copying and routing, etc.. Control Geek blog has just a new interesting posting related to this topic: Dante, AVB, and a Visit to the AVnu Testing Lab. Dante, AVB, and a Visit →
The future of cinema and TV: It’s game over for the hi-res hype article claims that all you’ve ever been told sold about moving pictures is wrong. In this article digital video guru John Watkinson (author of The MPEG Handbook) examines the next generation of TV and film and reveals it shouldn’t be anything like →
Last weekend I finally turned my Raspberry Pi to media player appliance (IP TV STB) using Raspbmc. Raspberry Pi reaches critical mass as XBMC hardware so trying it out sounded a good idea. My main was to use Elisa Viihde service also with my Rasberry Pi connected to monitor (I already had set-top-box and I →
I just wrote how to Turn a Tablet into a Signal Generator. In addition to generating signals, a tablet can be used as audio signal analysis. Typically the only way to get sound into those tablets and smart phones is through built-in microphone, which can be limiting. Here are some Android software for audio signal →
Signal generators are a handy thing to have around the lab. In recent years these lab tools have not only decreased in size but also in cost and the result has been a plethora of portable versions that now exist on the market. In addition to full equipment it is nowadays possible to use a →
