摘要： The addition of comfort noise to an image serves to hide compression artifacts. To facilitate comfort noise addition, supplemental information accompanying a video image contains at least one parameter that specifies an attribute regarding comfort noise. Typically, the supplemental information includes parameters that function to turn the comfort noise on and off, as well as to indicate the level of noise to add, based on the expected level of compression artifacts.

摘要： A video encoder and corresponding methods are provided for selecting the mode of a current macroblock of an inter-coded frame, including one or more of checking first modes for a subset of macroblock modes, selectively checking other modes in response to motion vector information of the checked first modes, and selecting the mode for the current macroblock in response to the checked modes; checking the macroblock mode of at least one neighboring macroblock, and selecting the mode for the current macroblock in response to the macroblock mode of the at least one checked neighboring macroblock; checking the cost of a subset of macroblock modes, further checking only intra-coded modes if the checked cost meets a preset criteria, and selecting the mode for the current macroblock in response to the checked modes; and adjusting an early-stopping threshold in response to checked macroblock modes, and selecting the mode for the current macroblock in response to the checked macroblock modes if the adjusted early-stopping threshold is met.

摘要： According to a general aspect, a picture from a first view, a picture from a second view, and dependency information are accessed. The dependency information describes one or more inter-view dependency relationships for the picture from the first view. Based on the dependency information, it is determined whether the picture from the first view is a reference picture for the picture from the second view. One application area involves determining whether pictures in a decoded picture buffer are reference pictures for pictures that have not yet been decoded. The pictures in the buffer may be marked to indicate whether they continue to be needed as inter-view reference pictures.
