摘要： In general, aspects of this disclosure describe example techniques for efficient usage of the fixed data rate processing of a graphics processing unit (GPU) for a variable data rate processing. For example, the GPU may be coupled to a pixel value processing unit that receives pixel values for pixels in an image processed by the GPU. The pixel value processing unit may determine whether the pixel values are for pixels that require further processing, and store the pixel values for the pixels that are required for further processing in a buffer.

摘要： The disclosure is directed to a video slicing technique that promotes low complexity, bandwidth efficiency and error resiliency. A video encoder places an RM close to the beginning of each logical transmission unit (LTU) so that all but a very small end segment of each video slice fits substantially within an LTU. Instead of requiring placement of RMs exactly at the LTU boundaries, a video encoder applies an approximate alignment technique. Video slices are encoded so that RMs are placed close to the beginning of each LTU, e.g., at the end of the first MB falling within the LTU. A portion of the last MB from the preceding slice carries over into the next LTU. Loss of an LTU results in loss of virtually the entire current slice plus a very small portion of the previous slice.
摘要翻译：本公开涉及一种促进低复杂度，带宽效率和错误弹性的视频切片技术。视频编码器使RM靠近每个逻辑传输单元（LTU）的开始，使得每个视频片段的除了非常小的端段之外的所有基本上都在LTU内。视频编码器不需要将RM完全放置在LTU边界，而是应用近似对准技术。视频片段被编码，使得RM被放置在每个LTU的开始附近，例如在第一MB的结尾落在LTU内。来自前一个片段的最后一个MB的一部分进入下一个LTU。 LTU的丢失导致几乎整个当前切片的损失加上前一切片的非常小的部分。

摘要： This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.

摘要： Methods and apparatus for control signaling in a communication system using continuous valued measurement and feedback are disclosed. The control signaling utilizes delta-sigma modulation where a measured phase or amplitude of a received signal is used to determine a difference signal by subtracting a previously quantized integrated difference signal from the current measurement signal, and then integrating the difference signal. The integrated difference signal is quantized and transmitted to the device originating the received signal as feedback control signaling. The device originating the received signal may then filter the control signaling to obtain the desired control information used to adjust or control the transmission of the signal transmitted by the device. By utilizing delta-sigma modulation, a greater degree of control signaling precision is achieved when controlling variables such as phase or amplitude of the transmitted signals, thereby achieving improved communication system performance.

摘要： The disclosure is directed to techniques for region-of-interest (ROI) processing for video telephony (VT) applications. According to the disclosed techniques, a recipient device defines ROI information for video information transmitted by a sender device, i.e., far-end video information. The recipient device transmits the ROI information to the sender device. Using the ROI information transmitted by the recipient device, the sender device applies preferential encoding to an ROI within a video scene. ROI extraction may be applied to process a user description of a region of interest (ROI) to generate information specifying the ROI based on the description. The user description may be textual, graphical, or speech-based. An extraction module applies appropriate processing to generated the ROI information from the user description. The extraction module may locally reside with a video communication device, or reside in a distinct intermediate server configured for ROI extraction.
