What is software-defined radio? A software defined radio system is a system in which the components are implemented in software instead of the traditional way of hardware implementation. It consists of an RF front-end followed by and analog- to-digital converter which provides samples to a host computer. The rest of the processing is done solely in software. Each student in the class will/or already gotten a TVB-T USB dongle based on the Realtek RTL2832U chip. This dongle was originally made to receive and decode the European standard digital television.

Last February, a V4L/DVB kernel developer, discovered that there is a device mode in which raw samples can be captured and transferred to a host computer. This feature enables this device to be used as an inexpensive ”Software Defined Radio”.

Inside the USB DVB-T Stick is the latest, highly sensitive, DVB-T Stick for the best TV reception. •Digital Video Recorder. Record digital TV programs to disk, and play them back to your PC screen in full original digital quality. Hmm, never thought to try my DVB-T stick in my mac, I only bought it for. May have the wrong drivers for the tuner type on the board then. Mac OS X 10.7 support Donations: $30 / $30 (Released) EasyCap eb1a:2861 (Empia Technology, Inc.) (Released) EasyCap 05e1:0408 (Syntek Semiconductor) Video version 10 support $120 / $120 (Released) July 14th, 2013: Due to life circumstances, I'm currently unable to work on EasyCapViewer much. I'm also significantly behind on my email, so many people who have emailed me over the past month have not received a reply.

This is a photo of the dongle: The E4000 Elonics chip is a digitally controlled tuner. The tuner selects a frequency band around a target center frequency and demodulates it to baseband. In our case, the RTL2832U chip serves as an analog to digital converter that samples the baseband signal and outputs the samples to a host computer through a USB2 port. The device uses IQ baseband demodulation and sampling. Here are some. Driver Installation Instructions All the installation instructions below were derived from the following links:. Here, we will provide you with binaries and basic installation that will enable you to get tune to a frequency and get samples into Matlab or GNU Octave.

If you are bold, you can go to the aove websites and follow the installation instructions. There are instructions there to install additional software, such as GNU-radio or SDR There are three tools you must be able to run:. rtltest: this will test the device and its function. rtlsdr: enables saving raw samples into a file. rtltcp: networked interface which we will use to dynamically load data into Matlab, change frequency etc.

MAC OSX:. Download and extract the archive. You should see the files: rtlsdr, rtltcp, rtltest, librtlsdr.dylib, librtlsdr.0.dylib,librtlsdr.0.0.0.dylib, libusb-1.0.0.dylib. If they do not exist, in the terminal, create the following directories.

You should see the file zadig.exe and two directories: x32 and x64. These correpond to 32bit and 64bit rtlsdr binaries. Plug your RTL device in for the first time, Windows may request a driver or automatically install a driver from Microsoft - this is OK as it will be replaced in the next few steps.

Don't install the software on the CD that comes with the device. Run the Zadig.exe file and you should see the following with an empty list:.

Click on Options and select “List All Devices”:. Choose the one that says “Bulk-In, Interface (Interface 0)”. This should be the primary endpoint of your RTL device:. In the box to the right of the green arrow make sure “WinUSB” is chosen - not libusb or libusbk. The big button underneath will say “Replace Driver” or “Reinstall Driver”. Before you proceed make sure the USBID matches the VID/PID.

Note that if you insert the dongle into a different USB port you may have to use Zadig again. It seems that you can change which driver is loaded depending on the USB port used. So you could use one USB port for RTLSDR and another port for using the dongle to watch DVB-T with the supplied Windows application. In a command line window, run the test.

This is the most user-friendly option so far. It will install the entire gnu-radio suit, which is lots of fun!.

Otherwise, follow the instructions on to compile and install binaries from source.

E4K range: 52 to 2226 MHz E4K L-band gap: 1114 to 1241 MHz Getting data into Matlab and GNU Octave There are a couple of ways to capture data and transfer it into Matlab. The most simple way is using the rtlsdr executable to capture data and save it into a file. Then, reading the data from a file into Matlab.

The other way is using rtltcp which enables communication with the device over TCP connection. I've written several matlab functions that can be used to interact with the device directly from Matlab. Unfortunately these do not work in GNU octave as they use Matlab built-in java interpreter. I will release GNU octave code soon.

Download and extract the archive. It contains all the code to work with the device from Matlab.

Using rtlsdr to capture to a file Example: to tune to 88.5Mhz and set the sample rate to 2.4Mhz use. y = loadFile('capture.bin'); You will see that the samples are complex! This is because the device uses IQ baseband demodulation and sampling to represent a single side of the spectrum. Here are some and about Quadrature demodulation and sampling.

Tamiya wild willy driver for mac. Because of the automatic gain, in many cases the first couple of seconds of capture will not be useful. You should therefore discard them. An alternative is to use manual gain, but you have to be careful not to overrange when the signal is strong. The Supported gain values (18): -1.0 1.5 4.0 6.5 9.0 11.5 14.0 16.5 19.0 21.5 24.0 29.0 34.0 42.0 43.0 45.0 47.0 49.0. Example: to tune to 88.5Mhz and set the sample rate to 2.4Mhz and maximum gain use.

rtlsdr -s 2400000 -f 88500000 -g 49.0 capture.bin Using rtltcp to capture and control the device directly from Matlab rtltcp comes with command line options which can be used to start the capture with specific frequency and rate. This is useful to save time but it is also possible to start rtltcp without and options, in which case it will start with default parameters. From Matlab it is possible to change these. Example: to start a tcp erver with default parameters of tuning to 88.5Mhz and sample rate of 2.4Mhz. soc = rtlsdrconnect;% open local tcp socket to rtltcp dummy = rtlsdrgetData(soc,2.4e6);% get 1 second worth of samples, and throw away y = rtlsdrgetData(soc,2.4e6);% get 1 second worth of samples soc.close;% close socket Immediately after invoking rtlsdrconnect, the device will capture data and buffer it. To flush the buffer, you can either use rtlsdrreset, or to read data till the buffer is flushed. To change frequency to 162.4Mhz and rate to 1Mhz and then capture data in Matlab use.

The EasyCAP video-grabbing gizmo is cheap to buy, almost everywhere and adds a really useful functionality to your computer. Better yet, it works perfectly on Yosemite to allow you to capture game consoles, VHS video, DV tapes, etc., directly into your Mac using MP4. The EasyCAP DC60 is a cheap old school video capturing device which is perfect for capturing old school video sources. If you have a ton of old video tapes or have some old video game consoles you want to grab walkthrough videos from, this is one of the very best cost-effective ways to do that. In this article we show you how to get set up and a few tips on how to configure the sound and video for the best performance.

For this test we will be using an old Ms Pac Man video game we found in the drawer. Cap Made Easy The is a USB device with video and audio input sockets to capture and store video on your computer. First, you need to go get the driver for Mac OS X, and that. Installing the hardware is easy; just plug it into an available USB slot. This needs to be a powered slot, so no dumb USB 1.0 hubs will do. Install and run the driver from the downloaded file, and if you haven’t plugged your EasyCAP into the computer, you will be advised to do so.

Now all you have to do is plug the yellow composite Video Out of your device to the yellow video plug on the EasyCAP. Configuring EasyCAP If it were that simple, then you could get started right away, but there are a couple of extra steps before you can play and record. First, you have to set the video standard.

This test was conducted in a PAL country, the UK, but your mileage may vary. If you get a weird picture which seems black and white, fuzzy and weirdly offset on the screen, then it’s likely your video standard is not right. You will spot the right one, even if you don’t know what your local standard is; just select one after the other and the screen will pop into colour when you have the right one. The next thing to set is the deinterlace. Old time video signals were interlaced, which doubled the amount of lines available by interlacing two frames and flicking rapidly between them.

The downside to this was that it made the screen flicker. These days we use progressive scan. You can combine the two images for smooth (ish) progressive images using the deinterlace setting. This is just trial and error on a case-by-case basis.

Just try each one to see which is the best fit. Finally, on the video side, you have to choose the source. This is effectively a choice between composite and SVHS or S-video. S-video is a small 4 pin DIN connector, and you will only find these on certain video cards and S-VHS recorders, so for the most part you will be using the yellow composite video in.

Sound is a separate issue. You can plug the sound into the white lead for mono or the white and red leads for stereo, but this didn’t work too well with the little Ms Pac Man for some reason, so in the end we added a small USB sound card and a phono to a 3.5 inch jack converter, and it worked perfectly. The cheap audio on the Ms Pac Man was really high, so we had to adjust the audio input which is available in the “Settings - Sound” section of the Mac Settings app. Recording Once you have a decent level on the sound, and you have the picture coming into the EasyCAP clearly and with the correct TV standard, you can record your video. Select “File - Start Recording” (Command + S), and you will be asked where you want to store the recording and what format to record in. MP4 is better for the Mac, so that was our choice. To stop the recording select “File - Stop Recording.” There are other display options on the menu such as Fullscreen and aspect ratios.

If you really want to squash the image and play it on full screen on 16:9, feel free to do so, but bear in mind what we said in. Hi guys, just to be clear, I’m not the developer of this software I just reviewed the device.

You should email the developer and ask for updates, but I wouldn’t hold your breath. The device is inexpensive and probably won’t be updated any time soon. For a variety of reasons I haven’t upgraded to Sierra yet, because I need to make sure that certain software I rely on will work properly first. When I do and if I find a patch or workaround, I’ll let you know.

It sometimes takes a while for people to work around new OS versions so it’ll take a while. If I get any info I’ll let you know. Thanks for getting in touch! Thanks for the thorough walkthrough. I’m eager to get moving here but am getting an error message at the first step. I’m running on Yosemite but even with the device plugged into the USB port, EasyCapViewer is telling me that “No supported capture hardware was found.” The error log reads: 2017-01-05 05:21:33 +0000: USB Devices: ( “(05ac:8006) Apple Inc.

Hi Brandon, well the device works for me on Yosemite, but in my experience with “out of the way” software and hardware is that mileage may vary between users. Is the device plugged directly into one of the USB ports in your computer or is it in a hub? I think the device draws a little power from the USB to function and so needs to be either in a direct link to the computer (I used an USB extension cable to avoid having the device hanging off the back of the Mac) or in a powered USB hub. Other than that, it might need a couple of deinstalls and reinstalls before the device is properly recognised.

This is not top quality hardware or software, that is clear, but if you can get it working on your system it’s a cheap and fucntional solution to the problem of grabbing Standard Definition video sources into your Mac. Comments are closed.
