摘要： Encoding and decoding systems for a digital image communication apparatus suppresses any reduction in the encoding efficiency due to leaky prediction. A range correcting unit (3) corrects the range of data of a preceding frame stored in a memory (1) according to a reference value outputted from a reference value outputting unit (2). Thereafter, a leak coefficient multiplying unit (4) multiplies the data by a predetermined leak coefficient and outputs the product data. The data outputted from the leak coefficient multiplying unit (4) are uncorrected by an uncorrecting unit (5) to restore the range corrected by the range correcting unit (3). A predictive error outputting unit (6) detects the difference between the digital image data of an inputted present frame and the data uncorrected by the uncorrecting unit (5), and outputs the difference as a predictive error. A predictive error encoding unit (7) encodes the predictive error outputted from the predictive error outputting unit (6), and outputs the encoded predictive error.

摘要： In an encoding system responsive to a sequence of coefficient signals which results from a predetermined linear transform and which is divided into a sequence of blocks, anterior processing is carried out prior to quantization about the coefficient signals in each block to determine a significant area of the coefficient signals by comparing each level of the coefficient signals with a threshold level. Only the coefficient signals within the significant area are judged to be valid and produced as a sequence of significant coefficient signals from a classifying circuit (20) to be quantized by a quantizer (15) into a sequence of quantized signals. The quantized signal sequence is subjected to posterior processing to produce a sequence of encoded signals. The significant area may be decided by the use of a selected one of zone detection, zigzag scanning, and adaptive scanning. In the posterior processing, the quantized signals may be encoded into the encoded signals by the use of a plurality of code sets or tables.

摘要： For an image data such as a motion picture image data composed of three hierarchical layers formed of slices, each of which having a plurality of macroblocks and one picture having a plurality of the slices, a synchronous word is adaptively inserted to each header of the slices and the picture according to a characteristic of the image data. It is possible to effectively perform the localization of errors. A synchronous word multiplexing system for coded image data inputs and codes image data, converts the coded data to a variable-length coded data, divides the image coded data into a plurality of data signals, and multiplies a synchronous word per a predetermined divided unit. Further, a timing signal for multiplexing synchronous words to the image coded data is generated based on a characteristic data, and the timing of multiplexing synchronous words is controlled based on characteristics of the image data.

摘要： An image data transmission system performs a coding of a plurality of picture elements in units of blocks. In order to prevent a deterioration of an image quality caused due to a loss of a packet cell on a transmission line without increasing a volume of data to be transmitted, a unit for producing a signal designating a loss compensation method to be performed on a receiving side is provided to be performed on a transmission side. The receiving side provides a unit for detecting a loss of the packet or cell and a unit for compensating the lost block data by the loss compensating method designated by the transmission side.
