Abstract: A technique is used in a speech encoder (107) that reduces non-speech activity of a
low bit rate digital voice message. Speech model parameters that include quantized
speech spectral parameter vectors are generated in a sequence of frames. A
determination is made as to which frames of the sequence of frames are voiced frames
and which frames are unvoiced frames. A consecutive sequence of frames of unvoiced
frames is identified (2330) as an unvoiced burst when a length, N UV , of the consecutive
sequence of frames exceeds a predetermined length, N S . A non-speech activity portion
of the unvoiced burst is identified (2335-2365) and removed.

Filed: 2000-12-28
Abstract: A disk recording medium has reliability of address
reading which is maintained equivalently to the conventional
disk recording medium by recording a first address and a
second address that are identical in a header area. By
arranging the first and second addresses to be reversely
displaced from the center line of a groove track or a land
track to the radial direction of the medium, the distance
between the first and second addresses when they are
adjacent is increased, which eliminates the influence of
crosstalk. This avoids redundancy of the header area and
enables high-density recording to the disk recording medium.

Abstract: An optical disk medium (110) has a data surface with grooves (124, 308) and lands
(126, 310) behind a transparent substrate. Periodically, along radial lines (306), tilt
measurement features (312, 314) are provided in the data surface, wherein the height of the
grooves and lands is abruptly changed, preferably over a short circumferential length. For
example, along the radial lines, the height of a groove (over a short length) may be
changed to the height of a land and the height of a land (over a short length) may be
changed to the height of a groove. The optical system (116) and the optical disk medium
are designed so that when the focused laser spot is centered on a groove, a radial push-pull
tracking error signal (figure 2, S1; figure 4, 400) is zero even if the disk is tilted. If the
focused laser spot is centered on a land, the tracking error signal varies when the disk is
tilted. As a result, when the focused laser spot passes over a tilt measurement feature, an
abrupt step in the tracking error signal (figure 2, S2, S3; figure 4, 402, 404) provides a
measure of the magnitude and direction of tilt. The tilt measurement features have little
effect on the data signal, and little effect on the filtered tracking error signal and the
filtered focus error signal.
