    Abstract: A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.

    Abstract: 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.

    Abstract translation: 图像传感器在将图像数据发送到DSP之前压缩图像数据。 图像传感器例如通过相机的光圈捕获表示图像的光。 焦平面阵列将捕获的光转换成像素数据。 像素数据被分类并被压缩引擎并行压缩。 压缩的像素数据然后被发送到可以位于芯片外的DSP。 然后，DSP解压缩压缩像素数据，对压缩像素数据执行图像信号处理操作，然后将经处理的像素数据压缩为数字图像格式。 图像传感器可以缓冲一个或多个图像的像素数据，以适应压缩引擎的减速。 像素数据可以按像素阵列的行和列排序。 或者，像素数据可以由拜耳滤色器的颜色分类。
