    摘要： An entropy encoding device and method, and an entropy decoding device and method are disclosed. The entropy encoding method comprises the steps of: dividing a transform unit into a plurality of zones, and dividing each of the plurality of zones into sub zones; setting, as the first value, the value of the last zone flag, in which a sub zone including a valid transform coefficient among the plurality of zones is included, and setting, as the second value, the value of a zone flag of the remaining zones; setting, as the first value, the value of a sub zone flag of the divided sub zones having the valid transform coefficient, and setting, as the second value, a value of a sub zone flag of the divided sub zones which do not include the valid transform coefficient; determining a preset coefficient coding scheme among a plurality of coefficient coding schemes on the basis of the zone flag and the sub zone flag; encoding a coefficient included in a sub zone on the basis of the determined coefficient coding scheme; and transmitting data on the zone flag, the sub zone flag, and the encoded coefficient.

    摘要： A thread dependency scheme may significantly reduce the dependency penalty and improve the parallelism efficiency in some embodiments in video compression techniques with relatively high dependencies, such as VP9. One fundamental feature is to split an individual large kernel into multiple, less dependent, smaller kernels, thereby significantly increasing the number of software threads that can potentially run in parallel. Another feature is to define the larger number of thread dependencies (superset of all the dependency candidates for each thread), with the specific thread's spatial position and associated context, and mask out some of the unnecessary thread dependencies.

    摘要翻译： 在具有较高依赖性的视频压缩技术（例如VP9）中的一些实施例中，线程依赖性方案可以显着减少依赖性惩罚并提高并行性效率。 一个基本特征是将单个大内核分割成多个较少依赖的较小内核，从而显着增加可能并行运行的软件线程的数量。 另一个功能是定义大量的线程依赖关系（每个线程的所有依赖关系候选的超集），特定线程的空间位置和关联的上下文，并屏蔽掉一些不必要的线程依赖关系。

    摘要： An encoder for receiving a video frame and performing encoding processes to generate an encoded bitstream includes: a fidelity enhancement block, for performing a fidelity enhancement technique on the video frame utilizing a quad-tree partition, and generating fidelity enhancement information including a parameter associated with the quad-tree partition structure; and an entropy coding block, coupled to the fidelity enhancement block, for encoding the fidelity enhancement information, and embedding the encoded fidelity enhancement information into the encoded bitstream.

    摘要： The present invention relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of images or video signals. In particular, the present invention relates to an improved memory management in an automated decision on whether to apply or skip deblocking filtering for a block and to selection of the deblocking filter. The decision is performed on the basis of a segmentation of blocks in such a manner that memory usage is optimized. Preferably, the selection of appropriate deblocking filters is improved so as to reduce computational expense.
