摘要： Disclosed is a method of controlling transmission of data transmitted in packets from a transmitter to a receiver via a channel. The method comprises transmitting packets from the transmitter to the receiver; determining if the transmission delay and/or loss of subsequent packets transmitted to the receiver may be reduced beyond a threshold amount; controlling the transmission rate to be dependent on a first target delay if it is determined that the transmission delay and/or loss of subsequent packets transmitted to the receiver may not be reduced beyond a threshold amount; and controlling the transmission rate to be dependent on a second target delay if it is determined that the transmission delay and/or loss of subsequent packets transmitted to the receiver may be reduced beyond a threshold amount, wherein the second target delay is lower relative to the first target delay.

摘要： A system and method for processing a narrowband speech signal comprising speech samples in a first range of frequencies. The method comprises: generating from the narrowband speech signal a highband speech signal in a second range of frequencies above the first range of frequencies; determining a pitch of the highband speech signal; using the pitch to generate a pitch-dependent tonality measure from samples of the highband speech signal; and filtering the speech samples using a gain factor derived from the tonality measure and selected to reduce the amplitude of harmonics in the highband speech signal.

摘要： A method of transmitting video data from a transmitter to a receiver, the method comprising: receiving data values of a video signal at a higher resolution; at the transmitter, combining groups of the data values into one or more first units of a first lower-resolution arrangement; encoding and transmitting the first lower-resolution arrangement to the receiver; at the transmitter, combining groups of the data values into one or more second units of a second lower-resolution arrangement, wherein the second units are offset from the first units by a fractional shift such that each second unit partially overlaps with at least one first unit; encoding and transmitting the second lower-resolution arrangement to the receiver; and transmitting an indication of said shift to the receiver; and at the receiver, combining the first and second lower-resolution arrangements based on the indication so as to reconstruct an image of at least a higher resolution than that of the first and second lower- resolution arrangements.

摘要： A video coding method includes for each target image portion to be encoded, selecting a preferred one of a set of encoding modes by optimizing a function comprising an estimate of distortion and a measure of bit rate required to encode the target image portion, the encoding modes comprising at least an intra frame mode and an inter frame mode; and transmitting the encoded video stream over a lossy channel. The estimate of distortion is based on a contribution from possible new loss over the channel comprising possible loss of the target block, and on a contribution from possible past loss over the channel comprising possible loss in a history of the encoded video stream upon which decoding of the target portion depends. The method includes accumulating the contribution from past loss over time, such that the estimate of distortion grows irrespective of the contribution from new loss.
摘要翻译：视频编码方法包括：对于要编码的每个目标图像部分，通过优化包括失真估计和编码目标图像部分所需的比特率的度量的函数来选择一组编码模式中的优选模式，编码模式至少包括帧内模式和帧间模式; 以及通过有损的信道发送编码的视频流。失真的估计是基于包括目标块的可能丢失的信道上可能的新损失的贡献，以及可能的过去在信道上的损失的贡献，包括编码视频流的历史中的可能损失，目标部分依赖。该方法包括随着时间的推移累积过去损失的贡献，使得失真的估计值与新损失的贡献无关。
