摘要： A system and method are provided for adaptive rate control in the transcoding of video streams. The method comprises: accepting frames of an input MPEG encoded video stream; decoding the video stream; determining video stream complexity; for each frame, calculating an output video stream quantization parameter (Qo) responsive to determined video stream complexity; and, encoding the output video stream into a protocol using Qo. Some aspects further comprise accepting a target bit rate ratio (r) for transcoding that is equal to the ratio of the target output video stream number of bits per frame (No), to the input video stream number of bits per frame (Ni). Then, Qo is also calculated in response to the value of r. More explicitly, Qo is calculated in response to a complexity ratio of: an accumulated complexity in the output video stream, to an accumulated complexity in the input video stream.

摘要： Errors are concealed in a decoded bitstream, such as a bitstream based on an H.264 protocol, by detecting macroblocks in the bitstream containing data errors. Each detected macroblock containing a data error is filled with prediction data. Each macroblock, whether containing no errors or containing prediction data, is then reconstructed by the same macroblock reconstruction module.

摘要： An introduction of nuclear fusion into conventionally fission-based nuclear reactors. Particularly, coolant in the reactor serves as the secondary fuel that absorbs neutrons from the fission core, and releases energy through fusion reactions. Molten Lithium is the preferred coolant in the invention, as it produces Helium gas through the neutron-Lithium fusion without leaving any radioactive or chemical impact to the environment. A Helium pressure controller is also introduced in the system to manage the Helium gas produced by nuclear reactions of the secondary fuel. Lithium Chloride (LiCl) is proposed as the secondary coolant in lieu of the commonly used molten salt in order to achieve higher power production efficiency. A reactor based on the proposed system requires less space than a conventional reactor of the same power. It is a better choice than conventional nuclear reactors when space is a key constraint, for example, on a container ship.

摘要： Techniques and tools are described for scalable video encoding and decoding. In some embodiments, an input frame is downsampled in terms of sample depth and chroma sampling rate, encoded, and output from the encoder as a base layer bitstream. The base layer bitstream is also reconstructed and upsampled to produce a reconstructed bitstream which is subtracted from the original input frame to produce a residual layer. The residual layer is split and encoded as a sample depth residual layer bitstream and a chroma high-pass residual layer bitstream. To recover the encoded input frame, a decoder receives one or more of these bitstreams, decodes them, and combines them to form a reconstructed image. The use of separate codecs is allowed for the base layer and the enhancement layers, without inter-layer dependencies.

摘要： Techniques and tools for encoding enhancement layer video with quantization that varies spatially and/or between color channels are presented, along with corresponding decoding techniques and tools. For example, an encoding tool determines whether quantization varies spatially over a picture, and the tool also determines whether quantization varies between color channels in the picture. The tool signals quantization parameters for macroblocks in the picture in an encoded bit stream. In some implementations, to signal the quantization parameters, the tool predicts the quantization parameters, and the quantization parameters are signaled with reference to the predicted quantization parameters. A decoding tool receives the encoded bit stream, predicts the quantization parameters, and uses the signaled information to determine the quantization parameters for the macroblocks of the enhancement layer video. The decoding tool performs inverse quantization that can vary spatially and/or between color channels.

摘要： Aspects of the present invention relate to systems, methods and devices for upsampling images and design of upsampling filters. Some aspects relate to a determination of a phase offset position in a higher resolution picture relative to a lower resolution picture. Interpolation filter coefficients for some filters may then be selected based on the filter offset. Other aspects relate to selection of coefficients for filters that are not dependent on the phase offset. In certain implementations, a weighting factor may be used to combine the effects of a phase-offset-dependent filter and an independent filter.
