摘要： In macroblock-based coding systems such as MPEG-1 video, MPEG-2 video and MPEG-4 visual, an encoder in the invention decides on macroblock level whether the macroblock is to be encoded or whether local motion-compensated interpolation processing at a compatible decoder can be used to reconstruct the macroblock. In the latter case, the macroblock is skipped. If the decoder detects a skipped macroblock, the decoder reconstructs the macroblock and overwrites the data conventionally generated in MPEG under the skipped macro-block condition.

摘要： The invention relates to a video encoder (201) for encoding a video signal. The video encoder comprises a segmentation processor (207) which divides the picture into picture regions. Preferably, picture regions having a high degree of flatness or uniformity are determined in this way. A characteristics processor (209) determine a spatial frequency characteristic for each picture region, and a coding controller (211) selects an encoding block size, such as a prediction block size for motion estimation, in response to the spatial frequency characteristic. An encode processor (213) encodes the picture using the selected encoding block size. Specifically, increasing block sizes are selected for increasing degrees of uniformity or flatness indicated by the spatial frequency characteristic. Thereby, an increasing proportion of high frequency components and a consistent choice of encoding block sizes are maintained, and thus the coding artefacts from many encoders having variable prediction block sizes is reduced. The invention is particularly suitable for H.264 and similar encoders.

摘要： A content augmentation process for personal recordings involves a service center (SC). The service center (SC) collects personal recordings from various different users via a network so as to constitute a database (DB) of personal recordings. The service center (SC) identifies personal recordings within the database (DB) that concern a particular scene and that are mutually complementary so as to form a selection of personal recordings (FSRR) for content augmentation purposes. The service center (SC) applies a content augmentation process (AUGP) to the selection of personal recordings (FSRR) so as to obtain an enhanced representation (CA).
