Abstract

2.1. In the case of a colour picture tube with horizontal colour strips and index strips, the index strips generate a signal by which the deflection is corrected. Due to the inertia in the control of the deflection currents, this control cannot take place quickly enough after determining the deviation. The object is to compensate for this delay in the control. 2.2. Measured values on the deviations in the position of the electron beam are determined in each case during a line, stored as digital voltage values in a memory (5, 6) and used in a following line for correction of the position of the electron beam. 2.3. In particular for colour picture tubes with flat screen for television receivers. <IMAGE>

Description

The invention relates to a system for programming the reproduction of recordings and/or information stored on a recording medium.

When playing music, voice and/or video information or signals, including text information from a recorded media, the problem is that the user does not want to hear and/or see all the recording contributions or information stored on the recording medium, such as music videos, texts and other information, but only a limited number or only individually desired recording contributions or information.

A playback device, e.g. a CD player, which, after inserting the CD, stores, among other things, the number, title number and jump address of a single recording, enables the player to retrieve only the desired contributions by means of a remote control, e.g. remote control, which requires entering all the desired title numbers of the desired recordings before the entire playback begins or entering the title number of the next desired contribution after the playback of a recording.

However, such playback programming is relatively cumbersome, since the user must act after each insertion of a CD or after playing each recording amount to enter the assigned title. If a CD player is able to store the corresponding title numbers for several CDs, the user will not know after a certain time which titles are automatically played from a CD.

DE-A-3842149 shows a playback programming for a CD which has an optically detectable area with a start mark and with specified manually markable points, each of which consists of several markable points along a radius forming a digital code for the position of a title on the disc. The programming is done on a label. GB-A-2232805 shows the possibility of industrially added bar markings describing the contents of the recording medium being read and evaluated by the CD player.

The present invention is intended to provide a system for user-programmed reproduction of recording contributions or information from a recording medium, which allows for simple and clear programming. Another task of the invention is to integrate existing recording media, e.g. compact discs, which do not yet have the features of the invention, into the reproduction programming system of the invention in order to easily retrofit them.

The first problem is solved by a system for reproduction programming which has the characteristics of claim 1. The other claims describe very advantageous arrangements of individual features of the overall system.

Record media that do not have such a section or table may be retrofitted with a sticky label or sticker as claimed by claim 6, where the section on the label or sticker has the aforementioned characteristics as described above.

The recording medium of the invention is very easy to program, the value-marking table on the recording medium is fixed and preferably inseparably connected to it, the programming or the assignment of a section of the area to a recording medium or title is clear to everyone, especially since a recording medium often contains information on the individual recording media.

The recording medium is preferably a CD or MOD (magnetoptic disc), photo CD or the like, which has a scan page and a label page, with the area arranged in the form of the table on the label page or scan page, and each markable location assigned a jump address of a recording entry of the CD or MOD. The jump address preferably represents the start of a recording entry. Preferably, when playback programming, the values to unwanted recording entries are marked (negative selection). It is also possible to program the additional value to be recorded by various types of marking, such as sound dynamics, sound bar, circular alpha marking, etc., at different places, such as a margin of discrete playback or dynamic marking.

Preferably, the markings of the items in the range are erasable, so that a simple reprogramming can be carried out.

A method for controlling a playback device with a recording device for a recording medium of the invention is given in claim 7.

Preferably, the marked and/or unmarked values shall be visually and/or audibly displayed on the playback device so that the user, after placing the recording medium in or on the playback device, is constantly informed of which recording entries are played back in sequence or in a selection order.

Since the recording medium is circular, such as a CD, MOD or disc, the table is scanned when the recording medium is rotated, so that the reading device for the area to be scanned can be fixed in the player if the area is on the label side.

Preferably, the recording medium shall have a constant rotation rate for the table during the scan process, and in particular in the area of the area or table where the points can be marked, the area should have equal size markers or fields to ensure the most error-free scan of the area to be scanned at a constant rotation rate.

The method can also be used to control a playback device equipped with a control system, which is trained as an automatic converter, whereby the control system allows the successive and/or selective playback of a large number of recording media, using a recording medium as described above and using a reading device in the converter or the playback device, whereby the reading device reads the local position of the marked and/or unmarked values and enters them into a memory in the converter. First, the playback of a first recording medium is started and the recordings assigned to one or more values are played back. The first recording is played back to a second recording, if all the recordings are played back by the first player or the first player, and the first recording is played back to the first player.

EP 0224465 provides a method for controlling an automatic converter with a control system that allows the successive and/or selective playback of a large number of recording media, but where the user enters once for all recording media a total number of recording inputs to be played.

Claim 12 contains a reproduction device of the invention for the system described in claim 1.

If the playback device contains a CD player or a MOD player that uses an optical scanner to scan the audio and/or video information from the scanning side, which is the side of the recording medium on which the audio and/or video information to be scanned is placed, it may be useful to have a separate reader on the side facing the label of the MOD or CD if the area is located on the label side, i.e. the separate reader is preferably located on the opposite side of the optical scanner to scan the audio and/or video information in the CD player or MOD player.

However, reading or touching of the area on the label or scanning side is also possible with the audio scanner if the reflectivity of the MOD or CD for light rays from the audio scanner is less than 100% so that the light rays can penetrate the MOD or CD.

Preferably, after touching the marked and/or unmarked places, the values for them or the reference marks assigned to the recording contributions, such as the recording contribution number, title number, title designation such as musical title, name of the performer, place and time of recording, etc., are displayed on a display of the playback device.

The following illustration illustrates the invention in more detail by means of a possible example of an embodiment. Fig. 1a a design of a CD recording medium according to the invention;Fig. 1a an alternative design of the area to Fig. 1a;Fig. 1a a drawing of a label to be affixed to a CD with the table in Fig. 1a;Fig. 1a an alternative embodiment to Fig. 1c;Fig. 2a diagram of a part of a CD player;Fig. 3a programming schedule of the system for programming recording contributions to a CD-exchanger device;Fig. 4a block-wide diagram of a CD player;Fig. 5a control panel of an open hardbox (e-leaf) for centering a label on the lab page of a CD.

Fig. 1a shows the label side of a compact disc 1 on which a tactile table or area 2 is located, in which tactile markings can be made selectively and manually on locally predetermined fields or spaces 3. The area forms an optically tactile code with the markings. The first ten digits one to ten are each assigned a specific title number 17 on the CD. The spaces eleven to twenty are unoccupied. The area is printed or pasted as a special label 4 on the CD on the label side of the CD. The format of the area or label is a circle of about 4 mm wide with a numbering of the numbers - one hundred and one next to the fields 3 (Fig. 1a, Fig. 1c) as the title number assigned next to the identification places.

In some cases, such a section or label is too wide to cover the outside edge of the label on the CD side when the label 4 is affixed. In the case of the version shown in Fig. 1b or Fig. 1d, the section is only as wide as the numbered markings, so that the section is narrower than in Fig. 1a and Fig. 1c. However, it is important for the user that the important information printed on the CD side, such as the table of contents 17, is not obscured by section 2 or the label and remains accessible without having to affix it, so as to ensure easy allocation of the title and the area to be marked at all times.

The outer edge of the CD on the label side is not usually marked with a label essential for the general understanding of the user, so that the area to be scanned can be easily and very advantageously accommodated there, as it has the relatively largest space for the narrow area 2.

The markings begin with a black and a white zone 5 and 6, which are used to synchronize a touch switch 7 (Fig. 2) in the playback device. This is followed by the twenty markers 3, where twenty unwanted musical titles 17 can be marked by coloring or filling in the relevant space in black. The first line is assigned to the first title 17.1, the second line to the second title, etc. The markers are joined in rotation by a black synchronization field 8a.

If the CD has only ten music titles, as in Fig. 1a, it is also useful to mark only titles one to ten. It is therefore easier if the number of places to mark on a CD is exactly the number of music titles.

According to Fig. 1c, the white zone of the three markers in the second area has a length of 5° (relative to the centre of the CD), corresponding to a length of about 5 mm. For this length there are correspondingly adapted waiting loops in the evaluation circuit or evaluation programme of the microprocessor system (Fig. 2).

The most reliable function of the touch circuit 7 was achieved with labels 4 made of white paper, marked with a black felt pen. Care should be taken to ensure that the contrast between the white and black spots is high enough. This may require a special felt pen with a special infrared absorbing colour if an infrared reflector is used as a reading device for the marked spots. Care should be taken when affixing the label and when marking the label to ensure that the sensitive label side of the CD is not damaged by scratches, softening in the adhesive of the label or in the writing fluid of a brand.

Another way of producing contrast is by means of pre-magnetized discs the size of a marker point. These are fixed to mark a point on the area and can be read by a magnetic scanner as a reading device in the CD player.

If the area 2 is already printed on the reflective material during the production of the CD or the labels have a metallic reflective surface, the necessary contrast can be achieved more easily.

A possibility of improving the quality of the reproduction of the desired recording contributions can be achieved by marking certain fields. To this end, the marking fields (3) in Fig. 1c in area 2 are each given a dividing line, e.g. in the middle or along the diagonals of a marking field. The user marks only half of a field if, in his opinion, this music title is played distorted, for example, by a scratch.The player will always operate normally in the compromise position if no half-field is marked, but will not be compromised by the shock-incompatibility of the recording contributions marked at half-field because scratches or other disturbances would cause a large shock if the user crosses the compromise. The advantage of this is that a player can operate in a compromise position without the possibility of an unpredictable shock.

To protect against damage, a CD 1 is regularly placed in a folding hardbox 51 (Fig. 5) and held in a defined position in a holder 57 there. The hardbox is very suitable for the exact application of a label 52 as shown in Fig. 1c or Fig. 1d, if the label is a detachable part of a sheet 53 inserted in the left flap 54 in Fig. 5.

Increasingly, CDs and MODs are placed in a cartridge (solid protective case) and are also played lying in the cartridge. To this end, after insertion of the cartridge, a slot is released on the scanning side through which the laser scanner gains access to the plate. According to the present invention, the cartridge on the label side in the marking section will also be made accessible if a separate marking scanner is used. This opening of the cartridge on the label side of the recording medium is essentially the size of a marking field. If the area of the scanner is scanned by the laser scanner, it is useful to create a very bright light layer on the adjacent lab-side in the appropriate way to reflect the brightness of the cartridge or the audio in a way that makes it very bright.

Figure 2 shows a touch circuit 7 with a microprocessor system to touch the marked points 3 in area 2 of CD 1 and process or evaluate the value sensed.

For the scanning of the markings in area 3 of the CD 1, an infrared reflector barrier of type MRL601 is used as a fixed reading device. It consists of an infrared LED 8 and a phototransistor 9 integrated together in a housing. A built-in infrared filter provides a high degree of safety in the presence of foreign light, so that the circuit can be checked and adjusted even when the device is open and under normal working lighting.

The MRL601 light barrier has a very good efficiency at a distance of 5 mm above the surface to be measured and is therefore mounted at this height above the outer edge (circuit) of the CD 1 in the CD player in the final position (playback position).

The phototransistor is connected to the non-inverting input of an operating amplifier of type TAA861 which amplifies the pulses of the phototransistor by means of a trim potentiometer 11 set at the correct level and connected to the inverting input of the operating amplifier.

The adjustment can be easily done by means of a two-channel oscilloscope, which compares the pulses at the phototransistor manifold with those at the output of the operating amplifier.

The phototransistor detects strong pulses produced by blacked-out markers and weak pulses produced by the thin markers 10 between the markers and separating them.

The strong pulses are reversed by a subsequent inverter 12 so that the bright surfaces in range 2 produce positive pulses.

The programming required for the upgrading of a CD player PD-7500 was achieved without any problems with the circuit shown in Fig. 2. The only thing required was to disconnect the original connection between a control IC (not shown in Fig. 2) and an infrared sensor 14 receiving command signals from a remote control, shown in Fig. 2. A full-block image of a CD player 18 is shown in Fig. 4. The microprocessor system, which is designed as a data processing unit, shown in Fig. 2, is integrated into the actual processor of the CD player, which processes the sampling signals from the 601 reading device.

The processing and evaluation (Fig. 2) of the pulses from the inverter 12 and the further control is carried out by the microprocessor system shown in Fig. 2, the heart of which is a Z-80 CPU processor. The entire circuit (except for EPROM 2764) is completely built in CMOS technology.

Two additional information are extracted from the CD player: an impulse is tapped at an IC (not shown) which is responsible for the movement of the slide on which the CD is pulled into the device, from which the microprocessor receives a RESET signal. Similarly, the microprocessor receives a RESET signal when the CD player is turned on.

The CD player is used to read the CD's contents, and the CD player is used to read the contents of the CD. The CD player is used to read the contents of the CD, and the CD player is used to read the contents of the CD.

After the analysis of the markings, the information must be passed on to the CD player. This is done by the Z-80 microprocessor simulating the corresponding control pulses of an infrared remote control. Therefore, the original connection between the infrared sensor 14 and the CD control IC is separated.

The CD player now displays on a display either the marked or unmarked title numbers. Since the marked places are assigned to the unwanted titles according to the agreement, it is useful to display the title numbers that are also played, i.e. the numbers of the places that are not marked except for the eleven places - twenty. The CD player now begins to play the titles assigned to the unmarked places in order.

The total-block switch image of a CD player 18 shown in Fig. 4 shows the reader 601 facing the label side of the CD 1 and the scanning laser 41 facing the scanning side of the CD 1 in the CD recording device 19 in the CD player.

Fig. 3 shows a flow diagram of a CD player trained as a CD-converter. The converter has a recording device trained as a recording box for a number of CDs. A control system allows for successive and/or selective playback of the recording media in the recording box.

The first CD is replaced with a second CD in the recording box when the recording contributions from the first CD assigned to the marked or unmarked positions have been played. These procedural steps of picking up, reading, playing and switching are repeated until all or a selection of the CDs in the recording box have been played.
