![]() ![]() SSTV is an acronym for Slow-Scan Television, which is a very popular method in radio transmission to send image data over a long distance via ionoshperic propagation. ![]() But before that I would like to talk about a method that you can use to encode your image data to audio and then use the Steganography method described in the next section to embed and extract the image from the carrier audio. In the next section, we will take a look at a frequency modulation based method to hide secret data in the inaudible frequency range. ![]() However, the carrier message has to have enough data bytes so as to carry all the bits of the secret message. As you can image, we can embed any text, document, audio, video within the carrier audio by simply encoding bits of the secret data within each byte of carrier audio. ![]()
