In this work, we address the problem of lossless compression of scientific and medical
floating-point volume data. We propose two prediction-based compression methods that …

MPEG-4 Audio Lossless Coding (ALS) is a new extension of the MPEG-4 audio coding
family. The MPEG-4 ALS codec is based on forward-adaptive linear prediction, which …

(57) Signal samples X in a floating-point format, each of which is composed of 1 bit of sign S.
8 bits of exponent E and 23 bits of mantissa M., are converted through truncation by an …

Lossless coding will become the latest extension of the MPEG-4 audio standard. The
lossless audio codec of the Technical University of Berlin was chosen as reference model …

In one embodiment of the method, a block of digital audio data is stored in a buffer, and a set
of parcor values are calculated for the block of digital audio data. Then, the parcor values …

In one embodiment, channel mapping information is added to configuration information for
the audio signal. The channel mapping information indicates to which speaker in a …

Thanks to the supercomputer, more and more complicated simulations are successfully
achieved. On the other hand, to analyze and understand the intrinsic properties of the big …

In one embodiment, a channel in a frame of the audio signal is subdivided into a plurality of
blocks according to a subdivision hierarchy. The subdivision hierarchy has more than one …

In one embodiment, the method includes receiving the audio signal having a plurality of
random access units. The random access unit includes one or more frames and at least one …
