摘要： The disclosure describes FGS video coding techniques that use cycle-aligned fragments (CAFs). The techniques may perform cycle-based coding of FGS video data block coefficients and syntax elements, and encapsulate cycles in fragments for transmission. The fragments may be cycle-aligned such that a start of a payload of each of the fragments substantially coincides with a start of one of the cycles. In this manner, cycles can be readily accessed via individual fragments. Some cycles may be controlled with a vector mode to scan to a predefined position within a block before moving to another block. In this manner, the number of cycles can be reduced, reducing the number of fragments and associated overhead. The CAFs may be entropy coded independently of one another so that each fragment may be readily accessed and decoded without waiting for decoding of other fragments. Independent entropy coding may permit parallel decoding and simultaneous processing of fragments.
摘要翻译：本公开描述了使用循环对齐片段（CAF）的FGS视频编码技术。这些技术可以执行FGS视频数据块系数和语法元素的基于周期的编码，并且将片段中的循环封装用于传输。片段可以是循环对齐的，使得每个片段的有效载荷的开始基本上与循环之一的开始一致。以这种方式，循环可以通过单个碎片轻松访问。在移动到另一个块之前，可以使用矢量模式控制某些周期以扫描块中的预定义位置。以这种方式，可以减少循环的次数，减少碎片的数量和相关的开销。 CAF可以彼此独立地熵编码，使得每个片段可以被容易地访问和解码，而不用等待其他片段的解码。独立的熵编码可以允许并行解码和同时处理片段。

摘要： Techniques for estimating distortion due to quantization of data are described. A histogram with multiple bins may be obtained for a set of coefficients to be quantized. Distortion due to quantization of the set of coefficients may be estimated based on the histogram and average distortions for the histogram bins. The number of coefficients in each bin may be multiplied with an average distortion for the bin to obtain a per-bin distortion. The per-bin distortions for all of the bins may be accumulated and scaled with a correction factor to obtain the estimated distortion. The techniques may be used to estimate distortions for a set of coding elements. Distortion and rate may be estimated for each coding element for each of multiple quantization steps. A set of quantization steps may be selected for the set of coding elements based on the estimated distortions and the estimated rates for the set of coding elements for different quantization steps.

摘要： The disclosure is directed to scalable motion estimation techniques for video encoding. According to the motion estimation techniques, a motion vector search is scaled according to the computing resources available. For example, the extent of the search may be dynamically adjusted according to available computing resources. A more extensive search may be performed when computing resources permit. When computing resources are scarce, the search may be more limited. In this manner, the scalable motion estimation technique balances video quality, computing overhead and power consumption. The scalable motion estimation technique may search a series of concentric regions, starting at a central anchor point and moving outward across several concentric regions. The number of concentric regions searched for a particular video frame or macroblock is adjusted according to computing resources. Upon searching the anchor point, the search proceeds outward to the next concentric region, and continues as permitted by available computing resources.

摘要： The motion estimation techniques and video encoding device(s) described use a two dimensional pipeline to generate accurate motion estimation parameters for a current video block. The two dimensional pipeline uses previously calculated motion estimation parameters of relevant neighboring video blocks, including a preceding video block on a same row as the current video block, prior to the generation of the accurate motion vectors, motion vector predictors, and mode decision of the current video block The use of the two dimensional pipeline allows accurate motion vector prediction from neighboring video blocks previously not available, in the computation of motion vectors. Three engines may be used in the two dimensional pipeline, a fetch engine, an integer search engine and a fractional and spatial search engine. While the fetch engine and fraction and spatial search engine operate on one row, the integer search engine operates on another row.
