Embodiments are directed to a companding method and system for reducing coding noise in an audio codec. A compression process reduces an original dynamic range of an initial audio signal through a compression process that divides the initial audio signal into a plurality of segments using a defined window shape, calculates a wideband gain in the frequency domain using a non-energy based average of frequency domain samples of the initial audio signal, and applies individual gain values to amplify segments of relatively low intensity and attenuate segments of relatively high intensity. The compressed audio signal is then expanded back to the substantially the original dynamic range that applies inverse gain values to amplify segments of relatively high intensity and attenuating segments of relatively low intensity. A QMF filterbank is used to analyze the initial audio signal to obtain a frequency domain representation.

In encoding a picture, comprising a plurality of tiles, into a bit-stream, a method and apparatus is provided for signaling the tile attribute values per-tile, using a compact syntax. These embodiments signal per-tile attribute values using a loop over the tiles. The tile attributes may, for example, be in the form of a set of tile syntax elements (one syntax element per tile attribute), or for example in the form of a set of flags to enable or disable the usage of the tile attributes. These embodiments provide freedom for an encoder to assign the tile attribute values per tile, or per any subset of tiles in a picture, and the attribute values are signaled in a compact syntax using a loop (or loops) over tiles.

A video encoding method of encoding a multi-view image including one or more basic view images and a plurality of reference view images includes determining a pruning order of the plurality of reference view images, acquiring a plurality of residual reference view images, by pruning the plurality of reference view images based on the one or more basic view images according to the pruning order, encoding the one or more basic view images and the plurality of residual reference view images, and outputting a bitstream including encoding information of the one or more basic view images and the plurality of residual reference view images.

An encoder operable to filter audio signals into a plurality of frequency band components, generate quantized digital components for each band, identify a potential for pre-echo events within the generated quantized digital components, generate an approximate signal by decoding the quantized digital components using inverse pulse code modulation, generate an error signal by comparing the approximate signal with the sampled audio signal, and process the error signal and quantized digital components. The encoder operable to process the error signal by processing delayed audio signals and Q band values, determining the potential for pre-echo events from the Q band values, and determining scale factors and MDCT block sizes for the potential for pre-echo events. The encoder operable to transform the error signal into high resolution frequency components using the MDCT block sizes, quantize the scale factors and frequency components, and encode the quantized lines, block sizes, and quantized scale factors for inclusion in the bitstream.

An image decoding method according to the present document comprises the steps of: receiving a bitstream including residual information; deriving a quantized transform coefficient for a current block on the basis of the residual information included in the bitstream; deriving a residual sample for the current block on the basis of the quantized transform coefficient; and generating a reconstructed picture on the basis of the residual sample for the current block, wherein the residual information may be derived via different syntax elements depending on whether a transform has been applied to the current block.

One embodiment is directed to a method of using variable-resolution quantization to front-haul at least some data over a front-haul network in a system configured to provide wireless service to user equipment. The method comprises, for each symbol position, determining a respective number of required resource blocks having respective actual user-equipment (UE) signal data to front-haul for each carrier and determining the number of high-resolution resource blocks that can be quantized at a higher resolution as a function of a difference between a nominal per-symbol-position front-haul link capacity and a link capacity needed to front-haul the required resource blocks for all of the carriers if quantized using a lower resolution. The method further comprises, for each symbol position, allocating the high-resolution resource blocks to each carrier and determining, for each carrier, which of the required resource blocks to quantize at the higher resolution. Other embodiments are disclosed.

A method includes: receiving, by a computer, a user input corresponding to selection of a link associated with an address; determining, by the computer, that the address would not fit in an address bar of a browser displayed on a screen of the computer; and based on the determination that the address would not fit in the address bar of the browser, displaying, by the computer, in the address bar of the browser, a first element of the address and at least part of a second element of the address, including displaying a first portion of the second element of the address and an ellipsis indication representing a second portion of the second element of the address. The display of the first element of the address is visually distinguished from the display of the first portion of the second element of the address.
