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： 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： Aspects describe a low receiver complexity approach for reliable packet decoding when Hybrid ARQ protocol is employed with persistent assignment and potentially an erasure sequence transmission. Multiple hypotheses packet decoding performance is achieved while mitigating multiple hypotheses receiver complexity. A reference number is utilized to perform hypotheses. The reference number is independent of a start of packet. A sequence of reference numbers can be utilized, which may not necessarily be sequential numbers. The reference numbers are pre-defined.

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.

摘要： An apparatus and method for performing speech signal compression, by variable rate coding of frames of digitized speech samples (10). The level of speech activity for each frame of digitized speech samples is determined and an output data packet rate is selected from a set of rates based upon the determined level of frame speech activity. A lowest rate of the set of rates corresponds to a detected minimum level of speech activity, such as background noise or pauses in speech, while a highest rate corresponds to a detected maximum level of speech activity, such as active vocalization. Each frame is then coded according to a predetermined coding format for the selected rate wherein each rate has a corresponding number of bits representative of the coded frame. A data packet is provided for each coded frame with each output data packet of a bit rate corresponding to the selected rate.
