Abstract: A system and process for pre-distorting TV shows and/or movie media enables digital transmission of the media via MPEG4/AC3 (or AAC) or MPEG4/AC4 codec for broadcast or streaming over the Internet with enhanced speech intelligibility. Processing of the entire media file is performed using pre-distortion techniques and algorithms including NN models (which includes DNN, RNN, CNN, and similar NN models) that are trained on perceptual codec induced noise, quantization noise, dynamic power level adjustment, frequency response adjustment, pitch and glottal impulse response adjustment, and other techniques. The pre-distortion process is iterative, and all combinations of pre-distortions to combat perceptual codec noise are attempted, and the result scored by an automatic speech recognition engine. The best speech recognition results and highest intelligibility scores are considered to indicate the best pre-distortion to be applied.

Abstract: A materials structure is presented which is based on the insertion of preformed nanocrystals of arbitrary shape on or into a non-crystalline, non-hydrocarbon barrier layer. Embodiments of the structure include a variety of barrier layers and contacts, which can be layered. When the structure is used as a detector or a solar cell, transport of charged carriers created in the nanocrystals during the absorption process occurs through quantum mechanical tunneling, thermionic emission or diffusion to electronic contacts. One embodiment of such a structure is a photovoltaic device, where a built-in bias is established using different contact materials and barrier layers. The structure can also be used as a modulator or emitter. The invention may consist of many structures stacked and sharing adjacent contact regions, where individual layers are tuned to absorb, emit or modulate light at a specific frequency or groups of frequencies.
