摘要： A signal converting apparatus and a signal converting method which predictively produce highly accurate interpolated pixels in accordance with a classification which precisely reflects a variety of signal characteristics of inputted video signals to provide a high resolution video signal. An activity is evaluated and classified for each block of an inputted video signal (S.sub.1), and stepwise classifications are executed on each block of the inputted video signal (S.sub.1) in accordance with an activity code (c0) obtained as a result of the activity classification. In this way, the accuracy of subsequent classifications can be increased, reflecting the activity characteristic of each block of the inputted video signal (S.sub.1), thus achieving, as a whole, a highly accurate classification of the inputted video signal (S.sub.1). Appropriate prediction coefficients (d1) are read based on the activity code (c0) and a class code (c1) for each block of the inputted video signal (S.sub.1) to produce highly accurate interpolated pixels, thus providing a high resolution video signal (S.sub.2).

摘要： Difference signals generated by the prediction encoding process for an input digital information signal are block segmented and then quantized by an ADRC encoder as a first variable-length-code encoding means. Output data of the ADRC encoder is divided into bit planes by a bit plane encoding circuit. The ADRC encoder varies the number of bits assigned to a block corresponding to a dynamic range DR. A block to which 0 bit has been assigned is detected in each bit plane and data of the block is excluded. The resultant data is encoded by a variable-length-code encoder as a second variable-length-code encoding means and then transmitted.

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： Encoded picture data or encoded difference data is decoded by an intraframe decoder. To an adder, zero data is given through a switching circuit at the time of the decoding of intraframe coded data, and when interframe coded data, i.e., difference data is decoded, a decoded value of a previous frame is supplied through the switching circuit. By the adder, the decoded value of the previous frame and the decoded difference value are added to allow the decoding of interframe coding.

摘要： An analog signal is quantized over a range of quantizing levels, each level being associated with a digital signal, and wherein the digital signals which are associated with a predetermined band of the quantizing levels have zero disparity. In accordance with one aspect, those digital signals which are outside the aforementioned band and which have non-zero disparity are selected to represent corresponding quantizing levels in such a manner that positive and negative disparity signals are selected, alternately, to represent quantized analog signals which are disposed outside the predetermined band. In accordance with another aspect, those zero disparity digital signals having the smallest run-lengths are assigned to represent quantizing levels which are disposed substantially in the center of the quantizing range, and those zero disparity digital signals having progressively larger run-lengths are assigned to represent quantizing levels which are disposed progressively farther from the center of the range.
