摘要
A method and apparatus for generating blocks of data for an image is described. An image is divided into a localized area 560. For each localized area, pixels are assigned to blocks 565 following a complementary pattern. The complementary pattern is designed such that most pixels are adjacent to pixels arising from other blocks. The neighboring pixels provide information that is useful for reconstructing data that is lost due to burst error. In one embodiment, this is used in the transmission of video signals over a potentially lossy communications channel.
