Abstract:
1. A method for encoding vibro-kinetic data onto an original LPCM audio stream to be packaged and synchronized with a video stream which is to be read by a video player, the original LPCM audio stream comprises a plurality of LPCM audio channels, the vibro-kinetic data for controlling a motion platform through a motion decoder, the method comprising: obtaining a succession of blocks of vibro-kinetic samples from a vibro-kinetic file; constructing a vibro-kinetic packet with each block of vibro-kinetic samples, the vibro-kinetic packet comprising a given number of bits, the bits representing at least a portion of the vibro-kinetic data; obtaining a series of original LPCM samples from at least one of the audio channels from the original LPCM audio stream; replacing at least the Least Significant Bit (LSB) of each LPCM sample of the series of original LPCM samples with a different one of the given number of bits of the vibro-kinetic packet to produce LPCM samples with encoded vibro-kinetic data; and assembling a given number of LPCM samples with encoded vibro-kinetic data to reconstitute an LPCM audio channel which thereby includes the vibro-kinetic data for controlling the motion platform, the LPCM audio channel for being transported over a digital link between the DVD player and the motion decoder.
