Described herein are systems and methods that provide for asymmetric image splitter image stream applications. In one embodiment, a system supporting image multi-streaming comprises an asymmetric image splitter engine that splits super-frame image streams into two or more image streams and a fractional clock divider circuit. The fractional clock divider may comprise a digital feedback control loop and a one-bit sigma delta modulator. The fractional clock divider circuit may provide compatible display clock frequencies for each of the two or more image streams. When a multi-image stream comprises the two image streams, the asymmetric image splitter engine adjusts a vertical asymmetry of a first image stream with a shortest height to same height as a second image stream by adding vertical padding to the first image stream. The super-frame image streams may comprise image streams from video, LIDAR, radar, or other sensors.

Quantisation methods are provided which employ dither techniques to reduce the noise penalty in certain circumstances whilst still removing noise modulation. One method relates to reducing the wordwidth of audio by one bit, while another method relates to burying one bit of data in a pair of signal samples.

The present technology relates to a signal processing apparatus, a signal processing method, and a program that make it possible to cope with an output of a PCM signal using one DSD signal. A distribution apparatus includes an extraction section that, in a case where a PCM signal having a predetermined sampling frequency is generated from a DSD signal, extracts a predetermined number of samples from the DSD signal around samples at a predetermined interval determined by the predetermined sampling frequency, and a filtering section that generates the PCM signal having the predetermined sampling frequency by filtering the extracted predetermined number of samples. The present technology is applicable to, for example, a distribution apparatus, etc., that distributes the PCM signal to a client apparatus.

The present disclosure relates to a compression/encoding apparatus and method, a decoding apparatus and method, and a program that allow for provision of a lossless compression technology with higher compression ratio. A GOB data configuration section configures GOB data with a group of digital data that includes a plurality of blocks by treating a frame of delta-sigma-modulated digital data as a block. A table generation section generates a conversion table for encoding the GOB data. An encoding section compresses and encodes the digital data of each block included in the GOB data by using the conversion table. The present technology is applicable, for example, to audio signal compression and encoding, and so on.

A second-order modulator includes a plurality of integrators and a parallel higher-bit processing part, and the parallel higher-bit processing part includes a plurality of addition and determination processing sections. The addition and determination processing section receives first and second carry inputs and first and second state inputs, and outputs a quantized output and first and second state outputs. A first selector selects one set from sets of the first and the second state outputs from the plurality of addition and determination processing sections and outputs the selected set, and a second selector selects one quantized output from the quantized outputs from the plurality of addition and determination processing sections. An output of the first selector is used as a selection control signal for the first and the second selectors.
