Matrix 4 channel stereo playback device
3. Detailed Description of the Invention The present invention is an apparatus for improving
perceptually equally and maximally the Sepia 932 page between channels for two kinds of input
binary signals with different encoding methods in matrix four-channel stereo reproduction.
About. The conventional matrix four-channel stereo reproduction device mixes the completely
separated (separate) two transmission system signals LT and RT, and synthesizes four direction
signals LIF, RF, DB and RB according to their combination ratio. Take them out and input them to
speakers arranged in 4 directions to reproduce the 3D sound field. That is, FIG. 1 is a so-called
cut-out pertorr diagram of a so-called 45-45 type disk record, where ox and aR are vector
diagrams of binary signals similar to those for conventional two-channel stereo reproduction.
The recording is performed with an inclination of + 45 ° and 45 ° with respect to the
horizontal axis of the record, and the sound is localized at the left center and the right center of
the listener, respectively. Then, OF is a vector of signals recorded by inputting the cutting input
in phase and at the same level in the horizontal direction, and this signal localizes the sound
image in the front center of the listener. Also, in the vertical direction, OB is a vector of a signal
recorded by inputting the cutting input at the reverse phase and at the same level as the end
page EndPage: 13 :) This signal localizes the sound image to the rear center of the listener.
One of the methods (hereinafter referred to as the matrix method (1)) of taking out signals in
four directions with the disc record subjected to such cutting as a signal source (hereinafter
referred to as 0), ie, the left front , Lf front left, right rear, \ right forward four-way channel and
signal out. As Rf and I + btRb, the structure is represented by following Formula. Lfmo、

38LT If this is expressed as a vector diagram, it becomes as shown in FIG. 8, that is, Lf and Xt are
respectively sandwiched by the reference horizontal line Oa. +25! , B ', -22i, and 5 ° direction
(with Ll: CTJf and the angle between xt are 46 °) I + 11. Ltf Ih et al. And the xb from R1 to the
45 'direction. However, the angle between IL and Lf is constant at 45 °. D. The angle between
the channels is θ, and the separation between each channel is divided by 8 (aB) sm 20 jog (OOs
45) )) -3 (aB), and 7 parisons are not sufficient even between offset channels.
There is another -M (hereinafter referred to as matrix method (2)) of the matrix method
described above. · Fig. 3 is a vector diagram of this method, and as it can be understood in
comparison with Fig. 1 and Fig. The binary signal I17,1'l'Tl (the method of exchanging (encoding)
the four signals of the field completely separated and the decoding method of extracting signals
in four directions from this eight-element signal are the matrix method (1) The left front signal
Lci of the original sound field and the right front signal 1tyq are cut as orthogonal vectors in the
4B ′ direction as in the conventional 2-channel stereo reproduction, and the left rear signal LB
and the right rear signal 1tBl It is cut with a phase difference of 98 pages oo on both sides 11 of
the 'j 45-460 sound groove. Due to this Phase difference, the "1 left rear" force signal
DB rotates clockwise and the right rear signal RB rotates counterclockwise (helical modulation).
The binary signal Xi thus encoded in this way. , RT is represented by the following equation.
LTam-jO, 'FO7 LB, -1- LP 100,' TO '71 BRT 〒-0, to 7 LB + 1? −) JO s 17 o f RB The left front,
right front, left rear, right taken out (using the basic decoder) of the binary signal LT obtained by
using a disc record subjected to such cutting as a signal source (using the basic decoder) One
signal is represented by T, r, Rt, Lb, Rb, and the configuration is expressed as follows: Lf 冨

and right channel rwJcXit-R1) and back left and right channel between (zb-Rh) 7 pages of 7
parallels good (in theory infinite) However, the number of seven pares braille on the left front
and back chan Leng R (between L · t and L1 and Rt and itb) and between diagonal channels
(between Xat and xb and between xt and IJb) is 3 dB. More than 10 conventional matrix-type JI!
The two methods have been described in the above, but at present butterfly (Mattori 7 # X
method ac appropriate I (special) seven valleys) improvement measures are implemented, and
hearing the crosstalk between each channel It is held down to the extent that there is no trouble
at all. However, since both methods are encoding method and decoding method S14, 1 especially
backward sound Kil, and there is no compatibility of Pdagram source ◇ That is, as seen from the
cutting vector diagrams of FIG. 1 and FIG. With regard to the signal ゝ located between the front
and left signals and the front right signal, and the signal at the rear center, both cutting vectors Fi
are similar (in the same plane) and temporary compatibility is recognized -While the movement
signal (direction of cutting) ore longitudinal direction of the rework needle is 1 matrix method (1)
with respect to the backward signal, EndPage: 2 page matrix method (in case of 2 movement of
the play needle, watch The direction and the counterclockwise rotational movement (helical
modulation) 9 are not compatible since both methods are completely different in this respect.
For example, as left rear signal LB: 1. When there is a signal of Q value (a) Two light signals LT1.
For R te 1, the signal in four directions, which is originally reproduced and is synthesized in the
decoder of matrix system (1), is Lν (1), R7 (1) tbit (1) tRB (1), matrix Assuming that signals of
four directions synthesized by the decoder of the system (2) are LP (2), Rv (2), LFI (2) and RB (2),

the absolute value of the signal this winter, LB (1) ssl, LF (1) xo, qoff, RF (1) snow0. RB (1) 謬

reproduce LB (2) LB0.70 rt, LP (32) s "on '9B; RF (2) = mo, s8, R , B (2)-0, word o 7 and the
reproduction level FiL? (2) becomes the maximum value, and the phase relationship is also
completely developed and reproduced, and as a result, it is generated with a single sound field
pattern which is completely compatible with the input signal. The localization of the sound image
is, of course, not completely fixed. · (B) Inversely, two light signals LTB, R? Encoded by the matrix
method (2). As opposed to 2, the signal "番 Ly (2)" to be reproduced originally (to be synthesized
by the decoder of the matrix system (2)) is to be reproduced. RP (2), DB (2), RB (2), page 9 signal

Since a signal of the same level is reproduced from the direction of rotation, that is, from the
direction of rotation, and phase 1 is completely different, the pattern of the reproduction sound
field is completely different from the encoding method of the input signal as described above. -Is
not all 1 o pages. Although numerical examples have been described above with reference to the
LB signal, the same applies to the signals of the left center OTJ and the right center OR, and both
methods have no compatibility with the vxf ram source. Therefore, for playback of matrix 4
channel records, a decoder of 2'1 lIIli is required, and in stereo playback sets provided with only
one type of decoder, there is a drawback that the type of encoding scheme of 4 channel records
is limited. there were. The present invention solves the above-mentioned drawbacks, and in
matrix channel 4-channel reproduction, two types (matrix systems (1) and (2)) input 2-light
signal LT encoded by the advanced encoding system. It is a matrix four-channel stereo
reproduction apparatus which can reproduce seven valleys between channels with respect to RT
equally and share the two types of promentem sources. Hereinafter, the present invention will be
described with reference to the drawings. Now, two types of binary signals LTIEndPage
represented by the following equations: Converting to 3 directions (channel) signals (decoding),

It becomes matrix type (1), and becomes matrix type (2). Here, in the matrix method (2) which is
the left rear, left front, right front, right rear signals of the I, B, IIF, Ry, Ra # i original sound field,
the general formula of the rear signals Lb, Rb is It is represented by. Here, the mixing ratio trm
27 mλ of the binary signals LT and BT is defined, and for convenience, the angle θ (1! It will be
1 if it is written in pages. Here we will consider the four-stalk s <e> between the rear left and
right. For example, when there is a signal with a value of 1.0 in the L'B channel, a binary signal
LT1 = jo, e2. The backward signal when RT1--jO 338 is input is represented by Rbmjo, 92 sin θ

Therefore, the value of (&) t (11) is taken as 81 (θ) + s2 (θ) on the vertical axis, and the angle θ
corresponding to the mixing ratio is taken on the horizontal axis as shown in FIG. From this, 8element signal i, 21. When mixing RTI and combining the back signal, O 2 O 0, that is, the mixing

order to make the order variance between the left and right of the 14 purchases be good
