摘要： Disclosed herein are exemplary embodiments of innovations in the area of encoding pictures or portions of pictures and determining whether and how certain encoding operations should be performed and flagged for performance by the decoder in the bitstream. In particular examples, various implementations for selectively encoding picture portions (e.g., blocks) in a skip mode (e.g., as in the skip mode of the H.265/HEVC standard) are disclosed. Embodiments of the disclosed techniques can be used to improve encoder efficiency, decrease overall encoder resource usage, and/or improve encoder speed. Such embodiments can be used in encoder modes in which efficient, fast encoder performance is desired (e.g., during encoding of live events, such as video conferencing).

摘要： A data compression apparatus and method suitable for image data assembles pixel values into plural groups. An encoding unit sets a maximum bit plane according to a highest value in the group, and encodes the data values sequentially along the group using iteratively reduced bit plane levels until reaching a lowest bit plane or exhausting the data values in the group, to provide a compressed dataset. Examples include recording a positional index where the bit plane level is changed within each group.

摘要： An information processing apparatus and method for reducing an unnecessary waiting time in a depacketizing process and enabling processing to be easily performed at high speeds applicable to, for example, an encoding apparatus. An analysis unit compares input image data with image data of one previous picture read out from a storage unit. On the basis of the analysis result, a concealment header generation unit generates a concealment header that is referred to by a receiving apparatus at the time of an error concealment process. On the basis of the concealment header, a loss analysis unit performs error concealment for the occurrence of a transmission error by suitably using encoded data stored in a storage unit.

摘要： Arrangements are provided for real-time variable compression and decompression schemes. In one arrangement, compressed images are stored as collections of tiled line textures representing breadth-first trees. In another arrangement, an image is decompressed directly on a GPU employing a microcode pixel shader. The arrangements allow for variable compression that can take into account complex local variations in light and shadowing. In this way, areas of high contrast may have significant detail preserved. The arrangement may be employed in a number of applications, including real-time shader image decompression, lighting and relighting, static shadow maps, dynamic texture packing, geometric representations, displacement maps, and so on.
