Abstract

PURPOSE:To attain recording while reducing the amount of data by recording addresses of picture element data on an original picture which correspond to respective origins of plural partial pictures to be reproduced as origin addresses. CONSTITUTION:A synchronizing signal is recorded in the 1st word S and a picture kind code is recorded in the 2nd word C; and write addresses are recorded in the eight low-order bits of the 3rd and the 4th words respectively. Then, the eight low-order bits of the 5th and 6th words are read addresses and recorded, header part by header part. When a picture which varies continuously, bit by bit, is obtained, origin addresses in the original picture surface are only recorded, so picture element data on every picture surface is unnecessary and the amount of data picture is less than when the picture element data are recorded on every picture surface. Thus, the recording is performed with the small amount of data.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a news recording medium and a reproducing device thereof, which records the origin address of +41i fraction 1 dust that changes little by little, Image 1 Sung pixel data should be recorded less JJ] H Ganki 9y medium, and] □i15
The object of the present invention is to provide an internal device that can read out each pixel image in a shorter time than it takes to read it out.

A digital video signal, which is pixel data for each pixel arranged in a nimatrix, is generated on the screen by pulse-modulating the original cog video image P on the original F'j light, and is used as a recording medium. We devised a method to record the results in 4 nos. In addition to the digital audio correspondence (in addition to the digital video signal for the color still image transmission as a W report, the change in the pit rows intermittent on the same track on the second disc) is shown as follows: °It is something to do.

On the other hand, the bit string on this disk is changed, for example, by electrostatic charge, to read and reproduce the exposed, recorded and hidden information.

This gi', 8. As shown in Figure 1, the structure of one field of digital video double brightness recorded on a disc using the f< method is a 16-bit, 6-word header section H1°H2.
j... and a 16-bit, 286-word digital video double length part V1. V2. ... are synthesized alternately and in chronological order. The header sections H1, H2, . . . are provided with memory addresses that designate predetermined memory addresses to be written into the memory of the digital video signal conversion and playback device. ’ is 111
Memory K 4pJ is included by Shingei, read-out system, 111
1 signal causes the memory to be read out.

By the way, each slightly different part of a still image, such as a landscape painting, is sequentially converted into a quadratic KM' raw (
7. The landscape painting looks like a television camera Y jj
In the case of playing back the images as if they had been taken with a JJJ, the recording disk that I proposed earlier would record a large number of images, each slightly different from the above. C

The present invention is above-13] Problem? It is solved, and the following is the -'l' along with the +IH! -jt(ifJK will explain.

FIG. 2 shows the main part of a digital video signal recorded on an embodiment of the news recording medium according to the present invention in a 16-mega format. In the same figure, the first word S (same r

The pixel data 7al of one still image of r is an address that can be inserted into the predetermined memory address of the memory for reproduction.

The lower 8 bits of the fifth and sixth words are read addresses, and are recorded with different values for each - ladder section, for example. Reading/Jj L address is horizontal axis part x1 in Figure 3

) is written as an origin address indicating all<1 of the origin.

The fingertip and bladder-out addresses are obtained by gamma-modifying only the pixel data address (origin address) at the upper left of the playback screen.

In this way, when obtaining the images shown in Figure 4) to (C) that change continuously little by little in the μ-shaped sequence, we simply record the origin address in the original screen. (C

B) Less data is required than recording pixel data for each image shown in FIGS. 34 (A) to (0).

Fig. 5 shows a block system diagram of an embodiment of the ii#'+li n self-playing device according to the present invention.In the figure, 1 is a disk, and Figs. 3 and 4 (A) Each signal has been recorded by the recording method explained in ~(C).The signals recorded on the disk 1 are recorded by the pickup circuit 2 as a change in the intensity of conventionally known C) or as a static output. The pick-up is from 1 town and 3 times.
After being demodulated by the demodulator 3, it is supplied to the decoder 4.

On the other hand, the address detector 7 detects the read address (origin address) shown in FIG. 2, extracts the detection signal, and supplies it to the memory read controller 9. Based on the origin address detected by the address detector γ.
The memory 6 selects the origin point based on the readout control signal from the memory write controller 9 out of the pixel data that has been written to a predetermined address by the memory write controller 8. Pixel data is read out using the address as a readout starting point.

For the origin address (x, y), the pixel data constituting one screen is read out as the original image coordinates (x, y)*origin shown in FIG. 3, and the origin address (x-1, 7
