A new generation of ambisonic decoding technology optimized for use with TV and HDTV is described. Based on B-format encoding plus optional supplementary channels, the new decoders give enhanced frontal stage image stability so that on-screen sounds are more aligned with on-screen visual images. The signal processing architecture of the new decoders differs from earlier designs, and is discussed in the paper, along with a detailed discussion of the psychoacoustic requirements to ensure optimum subjective localization quality around a 360 deg surround sound stage.
