摘要： Disclosed herein are systems and methods for implementing model-based quality-of-experience (QoE) scheduling. An embodiment takes the form of a method carried out by at least one network entity. The method includes receiving video frames from a video sender, which had first annotated each of the frames with a set of video-frame annotations including a channel-distortion model and a source distortion. The method also includes identifying all subsets of the received video frames that satisfy a resource constraint. The method also includes selecting, from among the identified subsets, based at least in part on the video-frame annotations, a subset that maximizes a QoE metric. The method also includes forwarding only the selected subset of the received video packets to a video receiver for presentation.

摘要： The invention relates to a method for transmitting digitized moving images (image data stream) from a transmitter to a receiver. The image data stream that is subdivided into priority classes is transmitted by means of a predetermined protocol to the receiver with the aid of an adaptation layer located at the transmitter. At an adaptation layer of the receiver, transmission errors are determined, subjected to an error processing and fed to an image decoder.

摘要：本申请实施例提供了一种编码、封装及显示方法、装置及电子设备。该编码方法包括：获取待编码的图像。接着，确定针对图像的编码尺度N(N为大于1的整数)，以及确定N种编码尺度中每种编码尺度对应的编码参数，得到N组编码参数。随后，根据N组编码参数，采用预先设置的单尺度编码器对图像进行N次编码，以得到N组码流数据。这样，针对该图像进行编码，能够得到数据量较小的码流数据(也就是低编码尺度的码流数据)，进而在网络波动时，图像的码流数据能够具有更高的概率到达解码端，从而保证视频播放的流畅性。而对于高编码尺度的码流数据，如果丢失，不会影响播放端的正常解码播放，不产生花屏；如果能够到达解码端，也能提升播放的画质。

摘要： There are provided mechanisms of guided transcoding. The methods are performed by a decoder, for producing original transform coefficients, and by an encoder, for producing coded delta transform coefficients. A decoding method comprises deriving a predicted residual block. The decoding method comprises transforming the predicted residual block using a forward transform, thereby producing a plurality of original estimated coefficients, the plurality of OECs comprising a first OEC. The decoding method comprises quantizing the plurality of OECs, thereby producing a plurality of quantized estimated transform coefficients comprising a first ETC corresponding to the first OEC. The decoding method comprises selecting a category based on the first OEC. The decoding method comprises decoding a first coded delta transform coefficient (DTC) corresponding to the first OEC, thereby producing a first decoded DTC, wherein the decoding comprises using the selected category to decode the first coded DTC. The decoding method comprises computing a first original transform coefficient by adding the first decoded DTC to the first ETC.

摘要： A method of encoding data on single level or variable multi-level cell storage includes receiving a block of encoded data from an approximation-aware application and at least an importance attribute associated with the block of encoded data; and assigning the block of encoded data to a memory address or a particular region of a memory having at least three precision levels, based at least according to the importance attribute. The importance attribute indicates a relative sensitivity of bits of the block to errors in an output quality from decoding the encoded data. An approximation-aware application can be an image encoding application having a modified entropy encoding step that enables identification and splitting of bits into groupings according to sensitivity to errors.
