scope:
This standard defines the image format, line format, synchronization method, and modulation method suitable for the transmission of images over noisy, low-bandwidth audio channels especially HF radio links.
Although substantial increases in picture quality (resolution and tray scale) could be obtained by utilizing modern quantization and compression techniques, the transmission time and complexity of implementing the required error free channel run counter to the intent of this standard.
