摘要： In a motion picture film of the present invention, audio data digitized from right channel analog audio signals is held in a recording region provided in a left channel digital sound track having the left channel audio data recorded in it, while audio data digitized from left channel analog audio signals is held in a recording region provided in a right channel digital sound track having the right channel audio data recorded in it. With a reproducing system for reproducing the motion picture film of the present invention, unless the left and right channels are destroyed simultaneously, the audio data reproduced from the sound track is used in substitution for the audio data from the destroyed channel to compensate for playback sound interruption.

摘要： The movie film has two tracks of left and right digital audio data recording areas in addition to a frame image information recording area in the form of frames, an analog audio data recording area, and left and right perforations. In these audio data recording areas, the same encoded audio data is recorded. Preferably, the audio data is constituted, using the encoding system called the ATRAC system, by the encoding parameter data, the encoded audio data, and the same parameter as the encoding parameter doubly written. This doubly written parameter is recorded in a manner so that when for example the encoding parameter and the encoded audio data are recorded on the left side audio data recording area for a certain channel, the tracks are switched so that the recording is carried out on the opposite right side audio data recording area.

摘要： With the signal encoding method and apparatus according to the present invention, noise components of plural channels are encoded individually by a first encoding unit 124, while noise components of plural channels are encoded in common by a second encoding unit 125. A discriminating unit 123 discriminates characteristics of noise components of plural channels. Based upon the results of discrimination, selective switching is made between an output of the first encoding unit 124 and an output of the second encoding unit 125. If the noise components of plural channels are encoded in common, the compression ratio for the noise components of plural channels may be improved. On the other hand, if the noise components of plural channels are not encoded in common, ill effects due to common handling can be prohibited.

摘要： An encoding method and apparatus for encoding multi-channel signals employed in, for example, a stereo system of a video disc player, a video tape recorder, a motion picture film picture system, or a so-called multi-surround acoustic system. Five channels, namely the center (C) channel, left (L) channel, right (R) channel, left surround (SL) channel and the right surround (SR) channel, for example, are handled in common depending upon frequency characteristic of digital audio signal and the targeted playback environment, and encoding is done while the combinations of the channels to be handled in common are altered. High compression may be achieved with the use of pre-existing encoding and decoding units by handling the channels in common without dependency upon the degree of correlation of multi-channel digital data.
