摘要： In aspects of the present disclosure, a software encoder augments a hardware encoder by implementing portions of a video encoding task that are not supported by the hardware encoder while the hardware encoder implements other portions of the encoding task. The use of a software encoder to augment a hardware encoder in this manner can extend the useful life of a hardware encoder, allow the system to adapt to changes in video coding standards, and in some cases improve performance of encoding implemented by hardware or software alone. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： A wavelet transform (WT) is applied to a data stream of high definition video frames, each comprising one or more data channels digitally representing the same image. A WT is applied to each channel. Visual-quality preserving data filters and data substitution techniques are selectively applied that typically lead to at least 90-to-1 compression of the final encoded video frame. Image edge data is extracted and preserved and image noise is reduced to enhance compressibility. After the first WT, primarily low frequency (LL) image data is retained. With each later WT, more non-LL data is retained. Temporal sequences of LL images that result from the final iteration of the wavelet transform are compressed by means of a chain of invertible differenced images. Any color space can be used. Cross-channel conditional substitution is applicable. Complete multiresolution scalability is incorporated into the encoded product. Extra-high definition video encoding is also achievable.
摘要翻译：将小波变换（WT）应用于高分辨率视频帧的数据流，每个数据流包括数字地表示相同图像的一个或多个数据通道。 WT应用于每个通道。选择性地应用视觉质量保留数据滤波器和数据替代技术，其通常导致最终编码视频帧的至少90对1的压缩。提取和保留图像边缘数据，减少图像噪声以增强压缩性。在第一个WT之后，主要是低频（LL）图像数据被保留。随着每个随后的WT，更多的非LL数据被保留。通过小波变换的最终迭代产生的LL图像的时间序列通过可逆差分图像链进行压缩。可以使用任何颜色空间。跨渠道条件替代适用。完整的多分辨率可扩展性被并入编码产品中。超高清视频编码也是可以实现的。

摘要： An image sensor compresses image data prior to transmitting the image data to a DSP. The image sensor captures light representing an image, for instance via a camera's aperture. A focal plane array converts the captured light into pixel data. The pixel data is sorted into categories, and is compressed in parallel by a compression engine. The compressed pixel data is then sent to a DSP, which may be located off-chip. The DSP then decompresses the compressed pixel data, performs image signal processing operations on the compressed pixel data, and then compresses the processed pixel data into a digital image format. The image sensor may buffer the pixel data for one or more images to accommodate for slowdown by the compression engine. The pixel data may be sorted by row and column of a pixel array. Alternatively, the pixel data may be sorted by color from a Bayer color filter.

摘要： Operating on video frames includes determining a frame set backdrop of a set of video frames that is a characterization of the relative difference in content of the set of video frames. Decreasing video quality of the set of video frames when the frame set backdrop is relatively higher indicating relatively greater content difference among video frames of the set of video frames and increasing/leaving quality of the set of video frames when the frame set backdrop is relatively lower indicating relatively lesser content difference among video frames of the set of video frames. Alteration of video quality of the set of video frames includes altering a frame rate, altering a pixel resolution, and/or altering color resolution of the set of video frames and/or altering a ratio of independent frames to predictive frames of the set of frames.

摘要： A method and apparatus for applying DF processing and SAO processing to reconstructed video data are disclosed. The DF processing is applied to a current access element of reconstructed video data to generate DF output data and the deblocking status is determined while applying the DF processing. Status-dependent SAO processing is applied to one or more pixels of the DF output data according to the deblocking status. The status-dependent SAO processing comprises SAO processing, partial SAO processing, and no SAO processing. The SAO starting time for SAO processing is between the DF-output starting time and ending time for the current block. The DF starting time of a next block can be earlier than the SAO ending time of the current block by a period oft, where t is smaller than time difference between the DF-output starting time and the DF starting time of the next block.

摘要： Methods, systems and devices are provided for efficiently receiving and displaying content in a mobile computing device. The computing device's reception and decoding operations are adjusted to match the capabilities of available device resources and/or to meet battery consumption needs/requirements. Higher level components (e.g., application layer components) selectively pull data from lower-level components (e.g., physical-layer or adaptation-layer components). The quality of video displayed is intelligently balanced against the amount of resources available, and a subset of the video data sufficient to display the content is pulled from the lower layer, providing users with an optimal balance between content quality and power consumption.
