摘要： Systems, apparatuses and methods whereby a base coded video signal is provided to a decoder having a set of post-processing stages. The base coded video signal can be decoded to produce a base decoded video signal. Post-processing of the base decoded video signal can be used to produce an enhanced quality video output signal. Application of a post-processing stage can be implemented according to the capabilities of the decoder and/or the instantaneous operating parameters of the decoder and/or characteristics of a display. A control signal, communicated over a dedicated channel separate from the base coded video signal, can be used initiate and/or aid implementation of a post-processing stage. The control signal can also provide information to assist/manage the decoding of the base coded video signal. The use of additional post-processing stages increases the complexity of an overall decoding process while improving the quality of a resulting reproduced video sequence.

摘要： Disclosed is an exemplary video coder and video coding method according to an embodiment of the present invention. The exemplary video coder includes a scheduler, a plurality of processors and a multiplexer. The scheduler can examine processing units in an input buffer to determine an order for the processing unit to be coded by a processor. If the processing unit under examination depends on a processing unit not yet processed, the processing unit under examination can be merged with other processing units, if any, that share a similar dependency. If the processing unit under examination does not depend on any processing units not yet processed, it can be sent to a next available processor for coding. When a processing unit is sent to a processor, any merged processing units that depend on sent processing unit can also be sent to a next available processor.
摘要翻译：公开了根据本发明的实施例的示例性视频编码器和视频编码方法。示例性视频编码器包括调度器，多个处理器和多路复用器。调度器可以检查输入缓冲器中的处理单元以确定处理单元由处理器编码的顺序。如果正在检查的处理单元依赖于尚未处理的处理单元，则被检查的处理单元可以与具有相似依赖性的其他处理单元（如果有的话）合并。如果被检查的处理单元不依赖于尚未处理的任何处理单元，则可将其发送到下一个可用的处理器进行编码。当处理单元被发送到处理器时，依赖于发送的处理单元的任何合并的处理单元也可以被发送到下一个可用的处理器。

摘要： A video decoder system includes a video decoding engine, noise database, artifact estimator and post-processing unit. The video coder may generate recovered video from a data stream of coded video data, which may have visually-perceptible artifacts introduced as a byproduct of compression. The noise database may store a plurality of previously developed noise patches. The artifact estimator may estimate the location of coding artifacts present in the recovered video and select noise patches from the database to mask the artifacts and the post-processing unit may integrate the selected noise patches into the recovered video. In this manner, the video decoder may generate post-processed noise which may mask artifacts that otherwise would be generated by a video coding process.
