    摘要： A method for effecting digital to analog conversion of PCM signals by a generalized interpolative procedure, by sampling the PCM signals at a first sampling rate and supplying each sampled word in succession to a first input of a digital adder; dividing each word at the output of the adder into a first part representing the higher value portion of the adder output word and having a length shorter than that of the adder input word, and a second part representing the lower value part of the adder output word; conducting the second part of each adder output word through a digital, nonrecursive counter feedback filter having a degree greater than one at a clock pulse rate which is an integral multiple of the sampling rate, and supplying each resulting word at the filter output to a second input of the digital adder where it is added to the stored word at the first adder input; converting the first part of each adder output word into an analog signal in a digital/analog converter having a small number of available output values; and passing the analog signal at the output of the converter through an analog lowpass filter.

    摘要： A motion compensating field interpolation method which allows the interpolation of several fields between every two transmitted fields of a digital television sequence. Using the model of translatorily displaced objects, a hierarchically structured displacement estimator is applied to cope with relatively large displacements. It provides a displacement vector with integer components for each picture element of the fields to be interpolated. A change detector is used to assure zero displacement vectors in unchanged areas. A two-coefficient spatio-temporal filter interpolates each picture element of the fields to be interpolated.

    摘要： In a method and apparatus for determining, in a system having a transmitting end and a receiving end, displacements of image features occurring between successively transmitted image sequences, by the operations of: determining, at the receiving end, peak values of pixel correlation between successively transmitted image sequences; deriving representations of estimated displacement values from the peak values of pixel correlation; and producing representations of optimized displacement values by a recursion operation which includes recursively deriving a correction value and adding the correction value to an existing estimated displacement value to form a new estimated value, the correction value is derived by performing a mathematical division operation in which the dividend is a selected function of pixel values in successive image sequences and the divisor is proportional to the average of a first value resulting from crosscorrelation of successively transmitted image sequences and a second value resulting from autocorrelation of the currently received image sequence.
