Abstract

PURPOSE:To reproduce a high picture quality even in a low transmission speed, by using an adaptive encoding device, which changes the sampling frequency in accordance with the speed of motion to compress an input TV signal, and using an adaptive decoding device which changes the coefficient in accordance with the speed of motion to interpolate the signal. CONSTITUTION:In the adaptive encoding device, a digital TV signal applied to an input terminal 100 is supplied to a vector detecting circuit 10 and an LPF11. The circuit 10 detects a dynamic vector, and a forecast error is detected by the LPF11, a sampling circuit 12, and a subracting circuit 13 and is supplied to a quantizing circuit 14. A code compressing circuit 19 compresses quantized forecast error and dynamic vector and transmits them to a transmission line 1000. In the adaptive decoding device, the picture signal supplied to the transmission line 1000 has the forecast error and the dynamic vector expanded by a code expanding circuit, and the output of an adding circuit is sampled in the speed of the dynamic vector, and an adaptive interpolation is performed in a picture interpolating circuit to output a restored TV signal to a terminal. Thus, the quantity of transmission information is limited, and a high picture quality is reproduced.

Description

[Detailed description of the invention] Kono Jealousy - Butterfly TV Show 0! Concerning detailed encoding and decoding of codes.

The pre-J encoding method is based on the operation of changing the transmission signal 1t-low line by transmitting the difference between the λ symbols to be 6R and the predicted signal, that is, the pre-#1wI4iM symbols.
1, this bar #4 gives this pre-Ill signal.
This is a child-side encoding and inertization device that prepares a large number of 1j functions and selects and uses the most suitable one from among them. For example, the seven-frame coding system is stationary.
A big t-1 against a single stationary koji that is too weak for IJ.
One prediction! l! Since the number of carp used in No. 4 No. 1g is low, the amount of information generated is small, and conversely, the amount of information generated is small, and conversely, the amount of information t #i generated increases for a movement that includes a large number of movements t. In other words, in frame human coding, the less motion there is, the better the coding efficiency is, but the more IIb there is, the lower the efficiency is. That's where the action is! Attempts have been made in many cases to maintain efficiency (even if written).

For example, since the motion contained in television broadcast signals is often considered to be parallel movement, it is relatively easy to detect the amount of change in the position of a subject in the human frame. The 5-j code, that is, the 7-frame kanyo-ku method is the most effective method for achieving high coding efficiency even for moving images.

<Movement 11 Sleeve Practice 7-Frame Preparation Method> In this dynamic movement practice frame-to-frame preparation method, many predictions are made to maintain the efficiency VrilIIl<VrilIIl< for Fi-'s electrodynamics.
J sll m &- becomes . In other words, the prediction function corresponding to the direction and tightness of each movement is prepared in advance. make a change. This Zhongwenyo Ayankan I5 [Fi-(2) corresponds to the direction of the movement l of the circle, 4th. Therefore, it can be said that the motion compensation frame prediction method adaptively determines the most common prediction number from among a large number of child functions and performs predictive coding.

Here, JIAMA will be briefly explained regarding this motion compensation. As shown in Figure 81, 1 = 1. At the moment of dawn
When the figure b shown near xo, y, ) is one frame I
It is assumed that l&11r*i has moved to ("1 + Yl).

At this time, in the normal frame person section, txt is used as the **1 column number on the l frame side. The prediction of a pixel in the figure shown near (x, y) at +τ is (X, at t ll:t,).

The ll1II tree in the garden shape shown near y.)fq is used. I want to #! From 1liitJ, ducks with a non-zero mJdi4% appear near both points ("@+F@) and (X1+71).

Here, if in some way we can convert (X・, y・) to (J +
Assuming that the figure's poor position 1t- can be drawn sideways to Yl),

s) The amount of generated information is significantly reduced by displaying the nearby figure association column. This is the so-called origin of motion compensation. As for the method of detecting this displacement, that is, the method of determining the wax transfer function, even #11978Todenshitsujikaitechnique! III Research-萱Vo178NLL89KIII 1st race Le Nitomi<x! Paper “Motion axis stop in 7-frame relational coding” (

In this sentence, if we apply motion compensation (in this sentence, it is placed as ``Doki Sode Masa'') to the 1ItJ #11 wife, we can obtain a motion compensation [Non-frame function? Approximately l/! of the generated information quantity in the case of only the liF encoding method. ! It has been shown that significant information @EE41II is possible.

◆Move in a fun way in this Futomi method! J indicating 1
It transmits the information expressed in detail by I14 and the difference in JIA of I11 when using this function.

However, due to the characteristics of human writing, the degree of dissociation is lower for the #'fkJaWB typeface than for the static typeface.

Therefore, as in method 25, when we hear something, it is the same as when we are at rest. Trying to re-invent ourselves with wrinkles is a matter of a degree of imitation that is higher than the degree of pleasure of the eyes. #
This means that all the information on the axis, that is, the 4 pieces of sea bream, is being transmitted. This Ill! If the transmission speed of the transmission line used is high, the quality deteriorates because the necessary information cannot be transmitted by the amount of information that is transmitted through #'i.

□ The purpose of this invention is to improve the encoding efficiency by slightly reducing the clearness of the signal and to improve the quality even when transmitted at a low transmission speed. An object of the present invention is to provide an adaptive encoding/reconstructing device for television signals that can efficiently condense the transmission of television signals.

That is, the adaptive encoding eQ of the television signal of this invention

A block consisting of one tree of 1411A is formed for each input television signal.
A maximum forward/missing function that makes * small is found, and the band is adaptively limited for each block of the input television signal t--by using this Nk forward/missing function or the speed of movement of 1-1.

This adaptively opens the band and converts the input television signal to the input television signal according to the degree of movement.
The number of wrinkles is equal to or less than the number of Ili#IL, and the prediction signal is calculated based on the television signal that has been converted into six lines and the prediction signal given based on the #IJ1 optimal prediction function.

〈Original salt in the open〉 I would like to take a moment to talk about the basics of this invention.

:1 subsampling) is shown. The reincarnation O mark indicates a book that will be converted into a 6-book book, and the x mark indicates a book that will not be converted into a p + book book and will be internally pressed when it is reincarnated as -.

In response to moving images, the visual characteristics (visual characteristics) of the eyes decrease.

In other words, humans! i1 is generally not enough for the detailed part of the moving body. When it is stationary, it is possible to make enough details in one line, and as the one guess becomes faster, it gradually becomes difficult to make one line.If p1 is very fast, K will be missed. In this @-, the visual % t- is used for the -A key information, and the detected motion vector is used as the -A key information.
If you lower the e, the savings in wax will be L1k. And if the resolution becomes useless, the speed of conversion can be lowered, so it is better to transmit! It becomes Makoto of the fII ring.

Therefore, in this invention, #i motion is uncertain and the unification mantissa is changed, but if the motion vector information is transmitted, it can be known with what sa number it was sampled in the Utsukuda negative. The next one can be reconstructed using an interpolation method suitable for each sub-sun link.

Note that in order to avoid re-bridge ruts, perform low-pass filtering before subsampling at the transmitter, and

That is, as shown in FIG. 3, sub-sampling of hm is performed and output at a speed of f,/2. 4<lvl≦6
When #IIJ becomes even tighter, an 8:1 sub-number printer is applied to this block.

The low-pass filter 11 limits the band to W/3, and the sub-sun full circuit 12 performs III3:1 sub-sun linking according to the third BK, and outputs the signal at f,/3, which is 4 degrees.

Further, when l v l>6 or more, 4 Fi4:t subsamplings are applied to the block corresponding to this V. According to the above and colleagues, the television signal input to this block is band-limited to W/4 and then subsampled 4:1 from the subsampling circuit 12 at a rate of f$/4.

The system sample ratio is determined based on the speed V of the motion vector supplied through 1I#1, and a transfer lock is supplied to the register 121. The relationship between this V and the subsample ratio is very interesting.
The example shown in Figure 7 can be used. As a transfer lock, when the sub-sampling ratio is n:1, the input television signal clock lI! It is preferable to use one obtained by dividing the lJ wave number f, into 1/n. In the case of n-1, the ratio is 11, that is, the transfer lock #kJ is f. Therefore, the sub-sample operation Fi does not occur.

The output of the sub-sample IgIM 12 is supplied to the #L circuit 13 via the 11211 link. The output of subsample 1@12 is subtracted from the motion-compensated signal supplied through the conversion circuit 18 Lingjima et al.
