Slow Scan Television - SSTV (.hrz)

The HRZ file extension is integral to Slow Scan Television (SSTV), a digital imaging technique used in amateur radio to transmit images via radio waves. The HRZ format efficiently stores images in a 256 x 240 RGB bitmap, making it ideal for low-bandwidth transmissions. SSTV encodes images into audio signals, which are then decoded back into visual files, producing an HRZ file. This technology is crucial for image communication in bandwidth-constrained environments.
