摘要： A method and apparatus for generating blocks of data for an image is described. An image is divided into a localized area. For each localized area, pixels are assigned to blocks 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.

摘要： On a decoding side, parameters (minimum value MIN and dynamic range DR) are optimized in such a manner that a decoded error of original signal values and restored values becomes minimum. A maximum value detecting portion 2 detects the maximum value MAX of pixels of each block composed of (3.times.3) pixels. Likewise, a minimum value detecting portion 3 detects the minimum value MIN. A subtracting portion 4 generates a dynamic range DR. A subtracting portion 5 subtracts MIN from each of input pixel values y and generates normalized values. A step width calculating portion 6 calculates a quantizing step width .DELTA. with DR. A quantizing portion 7 generates quantized values x (each of which is composed of 4 bits) with .DELTA.. A least squares method based estimating portion 8 generates decoded values y' with y and x and obtains an optimized dynamic range DR' and an optimized minimum value MIN' in such a manner that the sum of square of an error (y'-y) becomes minimum. A framing portion 11 frames x, DR', and MIN' and records the framed data on a record medium 15 through an error-correction-code adding portion 12, a modulating portion 13, and a recording portion 14.

摘要： Difference signals generated in the prediction encoding process for an input digital information signal are block segmented. The maximum value and minimum value of each block are detected. In addition, a quantizing step .DELTA. is calculated. An offset detecting circuit detects a zero position flag ZR and an offset off. The zero position flag ZR represents a quantized code that includes 0. The offset off represents the deviation between value 0 of difference signals and value 0 of restored representative values. A class category adaptive predicting circuit predicts ZR and .DELTA.. These values are not transmitted in other than exception process. With predicted values ZR and .DELTA., difference signals corrected with the offset off are quantized by a quantizing circuit.
