The 5.1 surround sound is encoded in the stereo wave for transmission and is thus compatible with any mono/stereo/matrix-style receiver. If played on a 5.1 audio set equipped with Neural Surround decoder, the watermarks (i.e. spatial cues) in the waveforms are detected and the signal is recovered to its original 5.1 form. The technology is similar to parametric stereo, in which a mono signal is recovered to stereo. The bitrate for XMHD surround broadcasts is ~70 kbit/s using aacPlus from Coding Technologies.
