Key aspects of Robot 36 color processing: Interlaced encoding - Color information is split across two consecutive scan lines: Even lines contain Y (luminance) and V (red chrominance) Odd lines contain Y (luminance) and U (blue chrominance) Signal timing: Sync pulse (9ms) followed by sync porch (3ms) Luminance signal (88ms) Separator signal (4.5ms) - Determines even/odd line Porch (1.5ms. VR2WOA I usually operate on 7MHz, 14MHz, 50MHz as well as UHF and VHF. Decode SSTV encoded audio signals to images.

SSTV Encoder Image encoder for Slow-Scan Television (SSTV) audio signals Modes Supported SSTV modes: Martin Modes: Martin 1, Martin 2 PD Modes: PD 50, PD 90, PD 120, PD 160, PD 180, PD 240, PD 290 Robot Modes: Robot 36 Color, Robot 72 Color Scottie Modes: Scottie 1, Scottie 2, Scottie DX Wraase Modes: Wraase SC2 180. Following SSTV modes are supported: Robot Modes: 36 & 72 PD Modes: 50, 90, 120, 160, 180, 240 & 290 Martin Modes: 1 & 2 Scottie Modes: 1, 2 & DX Wraase Mode: SC2-180 Old B/W or unsupported modes can be viewed in "Raw" mode.
On detection of the calibration header of a supported mode, the resulting image will be automatically saved to the "Pictures" directory and can be seen in the Image gallery. Thus far in my exploration of SSTV, I've found Android apps that either encode or decode: SSTV Encoder by Olga Miller Select a photo from your camera roll or the camera itself, and click the Play button. You can set different modes in the menu, but the default Robot 36 works well.
The application will spit the audio out of the default device. Robot36 - SSTV Image Decoder for Android, free and safe download. Robot36 - SSTV Image Decoder latest version: A free app for Android, by Ahmet Inan.
