Abstract: Examples are disclosed that relate to encoding data on a data-storage medium. The method comprises obtaining a representation of a measurement performed on the data-storage medium, the representation being based on a previously recorded pattern of data encoded in the data-storage medium in a layout that defines a plurality of data locations. The method further comprises inputting the representation into a data decoder comprising a trained machine-learning function, and obtaining from the data decoder, for each data location of the layout, a plurality of probability values, wherein each probability value is associated with a corresponding data value and represents the probability that the corresponding data value matches the actual data value in the previously recorded pattern of data at a same location in the layout.

Abstract: A computer-implemented method is provided. The computer-implemented method comprises: determining data to be encoded, the data comprising data elements that each have a corresponding type, length, and value; determining a list of values of data elements having a first type; encoding the list as a first portion of encoded data including an indication of the first type, the length of each value, and the value; encoding the plurality of data elements as a second portion of encoded data, wherein for each data element whose value is included in the list of values, the second portion includes an indication of a position of the value in the list, and wherein for each data element having a second type, the second portion includes an indication of the type, an indication of the length, and an indication of the value; and transmitting the encoded data for storage and/or decoding.

Abstract: Systems and methods are described for streaming media content. A first portion of a media content item is received at a bandwidth available to a user device, wherein the quality of the first portion is based on the bandwidth available. A second portion of the media content item is received at a decreased or increased bandwidth, wherein the quality of the second portion is based on the increased or decreased bandwidth available to the user device. The quality of the first portion and the second portion is determined. In response to determining that the quality of the second portion received at the decreased bandwidth is less than a quality threshold, the quality of the first portion of the media content item is reduced prior to sending the first portion to a playback buffer.

Abstract: A video transmission system includes a transceiver module that transmits a video signal to a remote device over at least one communications channel wherein the video signal is transmitted as at least one separate video layer stream chosen from, an independent video layer stream and at least one dependent video layer streams that require the independent video layer for decoding. A control module determines at least one channel characteristic of the at least one channel and chooses the at least one separate video layer stream based on the at least one channel characteristic of the at least one channel.

Abstract: Circuitry separates a modulation signal into digital sign and magnitude signal components. The digital magnitude signal is converted to an analog magnitude signal. The analog magnitude signal is the mixed with an in-phase or quadrature carrier signal under the influence of the digital sign signal and routed to a driver output stage.
