Abstract
There is described a method and device for encoding a vibro-kinetic signal (e.g., motion codes) directly onto a video player media (e.g., a DVD player) and for streaming the vibro-kinetic signal to a dedicated motion decoder in synchrony to the audio and video, while the movie support media (e.g., a DVD, a computer file, streaming data from a network) is being played. According to an embodiment, the multi-channel vibro-kinetic signal is encoded within one of the audio channels transported by the HDMI (High-Definition Multimedia Interface) link. Two methods are proposed to perform the encoding: Direct LSB (Least Significant Bit) Injection; and Perceptually Modulated Injection. There are also described corresponding decoding methods and motion decoders.
