摘要： Implementations generally relate to pre-charge phase data compression. In some implementations, a method includes computing prediction values for image data, where the image data is pre-charge phase data. The method also includes computing residual data based on the prediction values. The method also includes quantizing the residual data. The method also includes entropy encoding the quantized residual data. The method also includes refining an inverse quantized residual data based on one or more of the residual data and a number of left-over bit-budget after entropy encoding.

摘要： An extension to the motion-constrained tile sets SEI message provides functionality to signal all tiles are independently decodable and to signal the ROIs that may have more than one tile per ROI. With this extension, the functionality to redefine any independently decodable region-of-interest in a CVS at a coding tree unit level based on user interactivity is enabled. The extension supports the interactivity utilized in various applications such as interactive Ultra High Definition Television (UHDTV), dynamic high-quality zoom-in application, interactive on-demand, e-learning, smart surveillance and many other applications. Additionally, the temporal MCTS SEI message is able to be used by an encoder for tiled streaming to signal explicitly to the decoder that the decoder need only to display the ROI.

摘要： Spatial domain directional intra prediction has been shown to be very effective to remove the correlation between the pixels in the current block and reconstructed neighbors. In AVC, 8 directional prediction modes (plus the DC prediction mode) are defined. The prediction mode number is signaled to the decoder using a simple predictive coding method. The previous intra prediction methods have two major disadvantages: lack of precision for arbitrary directional patterns and accuracy lack of accuracy to exploit geometric dependency between blocks. To address these issues, a new method accurately predicts the intra directions from reconstructed neighboring pixels and differentially encode the intra directions. This allows a more precise directional prediction without the significant increase in the cost for transmitting the side information.
摘要翻译：已经显示空间域方向帧内预测对于去除当前块中的像素和重构的邻居之间的相关性是非常有效的。在AVC中，定义了8种方向预测模式（加上DC预测模式）。使用简单的预测编码方法将预测模式编号发信号给解码器。先前的帧内预测方法有两个主要的缺点：对于任意方向模式缺乏精度，并且精度不足以利用块之间的几何相关性。为了解决这些问题，一种新方法从重建的相邻像素准确地预测帧内方向并对帧内方向进行差分编码。这可以实现更精确的方向预测，而不会显着增加传输边信息的成本。

摘要： Dual-mode compression of images/videos for reliable real-time transmission includes a scalable block-based video compression. The method provides graceful quality degradations in case of channel bandwidth changes. Prediction for encoding is avoided, and the process is less complex with less memory requirements. The method involves processing each block independently with the advantage that errors are not able to propagate beyond current block boundaries. Two different encoding modes are used, natural image coding for acquired images and graphics coding for computer generated images. The proper encoding mode is chosen by comparing performance of the two modes for a particular block to be encoded. An embedded bitstream is generated by the encoder in accordance to the available channel bandwidth.

摘要： A codec extends the AVC standard in order to provide support for coding high resolution still image pictures within the AVC coding of a lower resolution video. The codec is capable of capturing an AVC video stream while concurrently capturing high resolution still images at random intervals relative to the video stream. Each captured high resolution still image is embedded within the video stream as a single layer bit stream. Each embedded high resolution still image signals or forces the start of a new GOP in the coded video sequence. The AVC standard is extended to include new syntax for the sequence parameter sets. In one embodiment, a modified sequence parameter set defines a new profile that signals the presence of a high resolution still image in sequence with AVC video.
