摘要： A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

摘要： An image decoding method supporting a plurality of layers according to the present invention may comprise the steps of: generating an inter-layer reference picture set with respect to one or more reference layers to which a current picture can refer; generating an initial reference picture list including the inter-layer reference picture set; and predicting the current picture on the basis of the initial reference picture list. Accordingly, the present invention provides a method for generating a reference picture list including a picture of a layer, which is different from a layer to be currently encoded and decoded, and an apparatus using the same.

摘要： Methods and apparatus for caching reference data in a block processing pipeline. A cache may be implemented to which reference data corresponding to motion vectors for blocks being processed in the pipeline may be prefetched from memory. Prefetches for the motion vectors may be initiated one or more stages prior to a processing stage. Cache tags for the cache may be defined by the motion vectors. When a motion vector is received, the tags can be checked to determine if there are cache block(s) corresponding to the vector (cache hits) in the cache. Upon a cache miss, a cache block in the cache is selected according to a replacement policy, the respective tag is updated, and a prefetch (e.g., via DMA) for the respective reference data is issued.

摘要： A device determines a Compact Multi-Pass Transform (CMPT) from a plurality of CMPTs. Additionally, the device decompresses CMPT parameters for the CMPT. In instances where the device decodes video data, the device applies the CMPT to a coefficient block to reconstruct a residual block and decodes, based on a predictive block and the residual block, a current block of a picture of the video data. In instances where the device encodes video data, the device applies the CMPT to a residual block to construct a coefficient block and generates for output information indicating coefficient values for the coefficient block.

摘要： System and method for improving operational efficiency of a video encoding pipeline used to encode image data. The video encoding pipeline includes a motion estimation setup block, which dynamically adjusts a setup configuration of the motion estimation block based at least in part on operational parameters of the video encoding pipeline and select an initial candidate inter-frame prediction mode based at least on the setup configuration, a full-pel motion estimation block, which determines an intermediate candidate inter-frame prediction mode by performing a motion estimation search based on the initial candidate inter-frame prediction mode, a sub-pel motion estimation block, which determines a final candidate inter-frame prediction by performing a motion estimation search based on the intermediate candidate inter-frame prediction mode, and a mode decision block, which determines a rate-distortion cost associated with the final candidate inter-frame prediction mode and determines a prediction mode used to prediction encoding the image data.

摘要： A hybrid video encoding method and system using a software engine and a hardware engine. The software engine receives coding unit data associated with a current picture, and performs a first part of the video encoding operation by executing instructions. The first part of the video encoding operation generates an inter predictor and control information corresponding to the coding unit data of the current picture. The first part of the video encoding operation stores the inter predictor into an off-chip memory. The hardware engine performs a second part of the video encoding operation according to the control information. The second part of the video encoding operation receives the inter predictor, and subtracts the inter predictor from the coding unit data to generate a residual signal. The second part of the video encoding operation then transforms and quantizes the residual signal to generate transformed and quantized residual signal, and encodes the transformed and quantized residual signal to generate an encoded video bitstream.

摘要翻译：编码复杂度和可实现的速率失真比之间的更好的折衷和/或实现更好的速率失真比是通过使用多重分割来实现的，这不仅是为了将连续区域，即样本阵列细分为叶片区域，而是使用中间区域也可以在相应的配置叶块之间共享编码参数。通过这种措施，在瓦片区域中本地执行的编码过程可以分别与编码参数相关联，而不必分别明确地发送每个叶片区域的整个编码参数。相反，通过使用多重细分可以有效地利用相似之处。
