Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guardtime slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

Abstract: In a first recording area of the disc, main information is recorded using an 8-16 modulation system in the form of pits, and by partially removing multiple radially-extending reflective films, sub-information is recorded in a second recording region using a phase-encoding modulation system. Identification information unique to each optical disc is recorded in the sub-information. The identification information and/or a password is used to access protected parts in the main information. The optical disc is a reproduction type disc. In addition to the optical disc identification information, encryption keys and/or decryption keys may be recorded.

The first video stream is digital data for outputting a component for one of the eyes (a right-eye or a left-eye) of a three-dimensional video (3D) or digital data for outputting a non-three-dimensional video (2D), the second video stream is digital data for outputting a component for the other of the eyes (a left-eye or a right-eye) of the three-dimensional video (3D). The first video stream includes a plurality of first interleave units, the second video stream includes a plurality of second interleave units, each of the plurality of first interleave units includes a plurality of frames, each of the plurality of second interleave units includes a plurality of frames, the plurality of first interleave units and the plurality of second interleave units have been alternately recorded on the optical disk. In at least a set of the first interleave unit and the second interleave unit, which are adjacent to each other, among the plurality of first interleave units and the plurality of second interleave units, which are alternately recorded on the optical disk, at least one frame of the plurality of frames included in the first interleave unit has the same time information as at least one frame of the plurality of frames included in the second interleave unit, and location information of the digital data for outputting the non-three-dimensional video ( 2D) and location information of the digital data for outputting the three-dimensional video (3D) have been further recorded on the optical disk. The reproduction apparatus comprises a reproduction section for reproducing a signal recorded on the optical disk based on location information of the first video stream and the second video stream, indicated by the location information of the digital data for outputting the three-dimensional video (3D), when the reproduction of a stream for the three-dimensional video (3D) is performed; a division section for dividing the reproduced signal into the plurality of first interleAve units included in the first video stream and the plurality of second interleave units included in the second video stream, a decoding section for decoding the plurality of first interleave units and the plurality of second interleave units; and an output section for outputting the decoded first interleave unit and the decoded second interleave unit based on the time information. The output section outputs the first video stream as a signal for one of the eyes (a right-eye or a left-eye) and outputs the second video stream as a signal for the other of the eyes (a left-eye or a right-eye).

Abstract: The present invention has an objective of realizing compatibility of an optical disk having a high resolution video signal recorded thereon and a system for reproducing the optical disk, with a conventional system for producing a standard resolution video signal. A high resolution video signal is divided by video division means into a main signal and a sub signal, and the main signal and the sub signal are MPEG-encoded. The stream of the main signal and the stream of the sub signal are divided into 1 GOP or more of frames. First interleave blocks 54 each including 1 GOP or more of the stream of the main signal and second interleave blocks 55 each including 1 GOP or more of the stream of the sub signal are recorded on an optical disk 1. A high resolution reproduction apparatus reproduces both the first and second interleave blocks to obtain a high resolution video output. A non-high quality picture reproduction apparatus reproduces only the first or second interleave blocks to obtain a standard resolution video output.
