摘要： Spatial domain directional intra prediction has been shown to be very effective to remove the correlation between the pixels in the current block and reconstructed neighbors. In AVC, 8 directional prediction modes (plus the DC prediction mode) are defined. The prediction mode number is signaled to the decoder using a simple predictive coding method. The previous intra prediction methods have two major disadvantages: lack of precision for arbitrary directional patterns and accuracy lack of accuracy to exploit geometric dependency between blocks. To address these issues, a new method accurately predicts the intra directions from reconstructed neighboring pixels and differentially encode the intra directions. This allows a more precise directional prediction without the significant increase in the cost for transmitting the side information.

摘要： The quantization parameters (QP) for Chroma are extended up to and more preferably to the same range as Luma QP (e.g., 0 to 51). Previous, values of Chroma QP only extended up to 39. Techniques are provided for determining extended Chroma QP values (e.g., for Cr and Cb) based on the Luma QP and picture level chroma offsets. In one preferred embodiment, slice level offsets are added making the method particularly well-suited for slice level parallel processing. The extension of Chroma QP enhances functionality, flexibility and friendliness of the High Efficiency Video Coding (HEVC) standard for various applications.

摘要： An extension of an adaptive loop filter includes, in the sequence parameter set, a bit is added to signal whether the "default" or fixed adaptive loop filters are to be updated for this sequence. If yes, then the new set of default filters are explicitly coded. In the picture parameter set, a flag is used to determine whether to update the default filters at the picture level. If yes, filter coefficients are transmitted. In the Slice Header, a flag is added to show whether the online filter and the fixed filters are both available for block-level switching or not. Block-level filter switching is also referred to as ALF's CU control parameters. In the LCU Header, the maximum depth (minimum block-size) for the ALF's CU control parameters (block-level filter switchings) is explicitly signaled.

摘要： A method and apparatus of using logical mode numbers during both prediction and coding in the bit stream, such as for high efficiency video coders (HEVC). These logical intra mode numbers are sorted based on angle which as a result leads to improved coding designs with fewer and smaller look-up tables, and a small gain in coding efficiency. Furthermore, by using this type of naming, the number of most probable modes (MPMs) can be readily extended since no additional tables are required. The use of three MPMs achieves a larger gain of 0.25% and 0.31% for the AI_HE and AI_LC cases, respectively.

摘要： Disclosed is an image encoder that divides (1000) a digital image into a set of "macroblocks." If appropriate, a macroblock is "downsampled" (1004) to a lower resolution. The lower-resolution macroblock is then encoded by applying spatial (and possibly temporal) prediction (1006). The "residual" of the macroblock is calculated (1010) as the difference between the predicted and actual contents of the macroblock. The low-resolution residual is then either transmitted to an image decoder or stored for later use (1010). In some embodiments, the encoder calculates (1008) the rate-distortion costs of encoding the original-resolution macroblock and the lower-resolution macroblock and then only encodes (1010) the lower-resolution macroblock if its cost is lower. When a decoder receives (1104) a lower-resolution residual, it recovers the lower-resolution macroblock using standard prediction techniques (1106). Then, the macroblock is "upsampled" (1110) to its original resolution by interpolating the values left out by the encoder. The macroblocks are then joined (1114) to form the original digital image.

摘要： Disclosed is an image encoder that divides (1500) a digital image into a set of "macroblocks." Each macroblock is encoded by applying spatial (and possibly temporal) prediction (1504). The "residual" (610) of the macroblock is calculated (1506) as the difference between the predicted content of the macroblock and the actual content of the macroblock. The residual is then "decimated" (1508) by taking an orderly subset of its values. The decimated residual (720) is then either transmitted to an image decoder or is stored for later use (1514). To recreate the original image, the macroblocks are first recreated from their received residuals. When a decimated residual (720) is received (1800), the values of the residual left out during decimation are interpolated (1806) from the values actually received. Using the prediction techniques (1808) along with the residual (610), the original content of the macroblock is recovered (1810). The macroblocks are then joined to form the original digital image (1812).
