NRSC5 Player

A rework of https://github.com/jasonayu/nrsc5player to a vertical and compact layout.

Thanks to jasonyu for his work

A Python-based graphical frontend for nrsc5 digital audio playback using an RTL-SDR dongle. Designed to be cross-platform (tested on Windows and Linux) and easy to run with minimal dependencies.

Requirements

• Python 3
• tkinter
• PIL
• imagetk
• pyaudio
• numpy
• nrsc5

Setup

Install Python dependencies. In Ubuntu most if not all of these can be found in the package manager.

Compile and install nrsc5. Windows: place libnrsc5.dll in C:\Windows\System32 or the root directory of this repository.

Usage

Run nrsc5player.py. The python executable on Windows will be called python.exe instead.

 python3 nrsc5player.py

Enter the FM frequency you want to tune and press "Play". Tuner will take a few seconds to connect and buffer. Subchannel buttons can be clicked once they are populated with info and enabled.

Configuration

---EDIT LINE 102 in nrsc5player.py for presets---

Click on the "Conf" button or right click anywhere on the player window and select "Configure" to bring up the config options.

• rtl_tcp Host: nrsc5 can connect to a remote rtl_tcp instance. Leave blank if connecting through local USB.
• Device Index: Change this if you have more than one device connected and want to specify which.
• Cache Logos: Station logos are transmitted only periodically, which means an unlucky user may see them only after a delay if at all. Enable this option to store logos locally for re-use.

Directory must be writable in order to store logos and config settings.

Themes

The right click popup menu also has a list of selectable themes as provided by the stock tkinter install.

Todo

I consider this feature complete, but there are a few things I'm not entirely satisfied with:

• Status bar updates are far less useful than they could be. A consequence of avoiding a race condition issue found when updating the UI through the nrsc callback.
• Improvements to UI look and feel? Would prefer themes that look a little less 1995 but are still respectful of limited screen real estate.
• Also interested in ways to properly set this up for compilation as a standalone application.
