摘要:
An interframe/interfield encoding system is for coding an incoming video signal having a successive specific number of dependent frames/fields, and independent frames/fields located anterior and posterior to the dependent frames/fields on a time axis. The system has a predictor for generating prediction errors of the dependent frames/fields by the independent frames/fields and an encoder for coding the independent frames/fields and the prediction errors. The system also has a delay section delays coding the posterior independent frame/field by the specific number of dependent frames/fields on the time axis to the incoming video signal and a controller, responsive to the delaying, controls the encoder to encode the posterior independent frame/field so as to follow the coding of the prediction errors. The posterior independent frame/field, without being delayed, is employed for generation of the prediction errors.

An efficient coding and decoding system is provided for a moving picture signal having independent and dependent frames. An interval between independent frames is varied in accordance with frame difference or amount of coded data. Predictive error signals are produced by subtracting predictive picture signals based on two of the frames, the interval therebetween thus varied, from picture signals of dependent frames. The predictive error picture signals and picture signals of the independent frames are then coded to produce a coded moving picture signal. When decoding, decoded predictive picture signals and predictive error picture signals are added to each other to reproduce the picture signals of the dependent frames. Decoded picture signals of the independent frames and the reproduced picture signals of the dependent frames are serially outputted to reproduce the original moving picture signal.

An inter-frame predictive encoding apparatus which derives a prediction error signal representing successive frames of a video signal based on differences between pixel data of each frame and pixel data of at least one other frame, and executes intra-frame encoding of the prediction error signal, in which the prediction error signal is transferred through a spatial filter prior to intra-frame encoding, and in which the degree of filtering is controlled fixedly or varying in units of frame intervals by a control signal, for thereby controlling the high frequency components of the error signal to an appropriate level in accordance with respective requirements for the output data rate from the apparatus and spatial resolution of a finally obtained picture.
摘要:
In an inter-frame predictive encoding system, reference frames are set. The reference frames are separated at equal intervals. The reference frames are selected from successively inputted frames of a video signal. Each of the reference frames is encoded. A prediction signal for a dependent frame between the reference frames is generated on the basis of a signal of the reference frames which precedes and follows the dependent frame respectively. A signal of the dependent frame is generated on the basis of the prediction signal corresponding thereto. An error of the predicting of the signal of the dependent frame is encoded.

A combination of a variable vertical-direction band pass filter and a variable horizontal-direction band pass filter extracts a color signal from a composite color signal. A vertical-direction variation detector detects a difference between levels of the composite color signal at sampling points separated vertically in a picture. A horizontal-direction variation detector detects a difference between levels of the composite color signal at sampling points separated horizontally in a picture. Pass bands of the vertical-direction band pass filter and the horizontal-direction band pass filter are controlled in accordance with output signals from the vertical-direction variation detector and the horizontal-direction variation detector. A luminance signal is derived from the composite color signal and the color signal.

摘要:
A luminance signal of each of first pictures to be used as reference pictures in inter-picture predictive encoding is encoded into a progressive moving-image signal whereas color-difference signals of each first picture are encoded into first moving-image signals having scanning lines decimated to one-half of scanning lines of the progressive moving-image signal. On the contrary, a luminance signal and also color-difference signals of second pictures not to be used as reference pictures in inter-picture predictive encoding are encoded into second moving-image signals having scanning lines decimated to one-half of the scanning lines of the progressive moving-image signal. The progressive moving-image signal and the first and second moving-image signals are combined into a color moving-image bitstream.
