About the testbed

 

This demo is designed as a testbed to test our cross-layer wireless video algorithm and also free to download for interested reader.

 

 

How to setup the environment?

 

Before run this demo, you should install GNU Radio in two PCs, one as transmitter and another as receiver. We suggest to use Linux OS to install GNU Radio environment, which may be downloaded here. If you have any questions about GNU Radio, you may use put your quesitons in mailing list. You also need to purchase two USRPs with RFX900 daughter boards. Here is about how to test USRP when you get it. To run version 1.0, you also need a third PC with windows OS.

　

1st PC with Linux:

    1) Unzip version_1_0_080318 and put folder version_1_0_080318 under gnuradio/gnuradio-examples directory


2nd PC with LInux:

    1) Unzip version_1_0_080318 and put folder version_1_0_080318 under gnuradio/gnuradio-examples directory

　

3rd PC with Windows:

    1) Simply put the H264_display.exe file into any folder.

　

　

How to run the program?

 

First, Connect two sets of USRP to your two Linux PC, and power on both USRP. Then:

In Windows PC:

    1) double click H264_display.exe to run the program.

    2) press setup button to run the UDP server

In 1st PC with Linux:

    1) Under gnuradio/gnuradio-examples/version_1_0_080318 directory, input ./rx_H264.py -f 900M

    2) Terminal will display "please input UDP server IP address", input your UDP server IP address here, that is the IP address of Windows PC.

    3) Terminal will display "please input UDP server port", input your UDP server port here. Default is 50007

In 2nd PC with Linux:

    1) Under gnuradio/gnuradio-examples/version_1_0_080318 directory, input ./tx_H264.py -f 900M

　

You will see a video display on Windows PC, and at the same time, you should see the data transmission information from both 1st and 2nd PC with Linux. To stop the video, you may stop tx_H264.py first and then rx_H264.py, the video display on Windows PC will stop accordingly.
