Description

[0001] INTERACTIVE DIGITAL VINYL SYSTEM WITH TOUCHSCREEN FOR DJS

[0002] The invention relates to a device and a method according to the preambles of the independent patent claims.

[0003] It is well known that music playback on a record player can be influenced by manually changing the angular speed or direction of rotation of a record while it is essentially rotating on the record. DJs have developed special techniques to achieve special sound effects. These include scratching and needle dropping. When scratching, the record is often moved quickly several times, alternately clockwise and counterclockwise, causing the music to play forwards and backwards in rapid succession. With needle dropping, the arm of the record player with the needle is dropped onto specific points on the record in order to start or continue playback of a piece of music at a specific point.

[0004] However, records have a decisive disadvantage compared to digital storage options due to the physical encoding of music, as only a limited number of pieces of music can be stored on a record.

[0005] If a DJ wants to create a varied program, he often has to change the record to switch to the next piece of music when using conventional records.

[0006] Therefore, other methods for playing music have also become established, relying on music stored digitally in a database. These often involve a mixer with one or more wheels, so-called jog wheels, to mimic scratching, for example. However, the DJ will notice a significant difference compared to scratching with a conventional record, as the wheels are usually much smaller than records and often don't rotate on their own.

[0007] REPLACEMENT SHEET (RULE 26) Another advantage of digital media files is that not only music, i.e. audio files, can be played, but also video files.

[0008] Methods have been developed to improve the feel for the DJ while simultaneously allowing the playback of digital media files. For example, records can be used which essentially produce a continuous tone when the record is played without interference. If influenced, the frequency of the tone changes, for example. The produced sound is analyzed by a device and the playback, for example the speed of the media file being played, is adjusted by a computer depending on the detected frequency. This can create a playback effect that is very similar to scratching, both in terms of sound and in the feeling it conveys to the DJ. One disadvantage, however, is that the continuous tone records used wear out and become unusable over time and therefore have to be replaced at regular intervals.Another disadvantage is that the continuous tone of the record is audible and thus disrupts the sound result.

[0009] Another well-known way to play digital media files while improving the haptic experience for the DJ is to place a rotation sensor on a conventional record and use it to determine the rotation speed or changes in rotation speed. This data is then used by a computer to control the playback of a media file, adjusting the playback speed or creating a scratch-like sound effect.

[0010] However, both of the aforementioned options for playing digital media files while improving the DJ's haptic experience do not allow, for example, the creation of a needle-dropping effect directly by manually operating the record. This requires an input, for example, on the computer, that specifies the point to which playback should jump. Likewise, neither method allows direct access to a database via the record. Access to the database, for example, to select a file to be played, can only be achieved via another device, such as a computer. Therefore, neither option offers convenient access to digital databases and media.Known methods for controlling the playback of digital media files such as audio and / or video files from a database therefore do not adequately provide a DJ with the opportunity to combine the advantages of digitally stored media with the convenience and familiar feel of conventional records.

[0011] The object of the invention is therefore to overcome the disadvantages of the prior art and in particular to improve the usability of the playback of media files, especially by DJs.

[0012] These and other objects of the invention are solved by the independent patent claims.

[0013] The invention particularly relates to a device for controlling the playback of digital media files such as audio and / or video files from a database. The device comprises a control unit and a computer device. The control unit is designed for rotating operation on a conventional record player. The control unit comprises a rotation sensor for detecting, for example, gyroscopically, data on the angular velocity of the rotating control unit. The control unit comprises, on one of its flat sides, a touch-sensitive surface for detecting touches and touch gestures and at least one display. In particular, the control unit comprises a touchscreen. The touch-sensitive surface and the display form at least one control element operable by touch or touch gestures for generating playback parameters and controlling audio or video playback.

[0014] Optionally, the control unit may include a communication device. The communication device may be provided for communication between the device and an external device. Communication may, in particular, be wireless. The external device may, in particular, be provided as an output device. Communication preferably occurs for transmitting the playback parameters, the angular velocity data, and / or audio signals.

[0015] Optionally, it can be provided that the control unit includes the computer device. The communication device sends generated media output signals to an external device, preferably to an output device. Optionally, it can alternatively be provided that the computer device is arranged separately from the control unit. Preferably, the computer device is provided as an external device or as part of an external device, for example, a computer. The communication device sends acquired data on the angular velocity and playback parameters to the computer device.

[0016] Optionally, the control unit may be provided with a wireless power supply. Alternatively or additionally, the control unit may be provided with an integrated rechargeable battery. Alternatively or additionally, the control unit may be provided with a battery compartment for batteries. This may preferably provide the power supply to the control unit, in particular to the rotation sensor, the touch-sensitive surface, the display, and / or the communication device.

[0017] Optionally, the control unit can be designed essentially as a cuboid box, the length of which does not exceed approximately 10 cm, the width of which does not exceed approximately 5 cm, and the height of which does not exceed approximately 2.5 cm. During operation, the control unit can be placed or glued onto a record with one of its sides, which is spanned by its width and length. This allows the invention to be easily integrated and used in existing DJ sets with minimal modifications. Furthermore, the invention is easiest to transport in this form.

[0018] Optionally, the control device can be designed essentially as a disc, with a diameter not exceeding 10 cm and a height not exceeding approximately 2.5 cm. It has a recess 18 for receiving the centering pin of a record player, and the control device can be placed or glued onto a record with one of its circular sides centered during operation. This allows the invention to remain easy to transport and integrate into existing systems. However, the usable button is larger, while at the same time the playability of a record is not restricted.

[0019] If necessary, the control unit can be mounted detachably or permanently on a timecode control vinyl record (TCVS). This increases the operational reliability of the device.

[0020] If desired, the control unit can be designed in the shape of a record, with a recess for accommodating the centering pin of a record player. This offers the advantage of a significantly larger control surface while maintaining the same operating feel for the DJ, as if it were an analog record.

[0021] If necessary, it can be provided that the flat side, in particular the touch-sensitive surface in a central area of ​​the control unit, comprises a display for showing graphic content, such as album covers or videos.

[0022] If necessary, it can be provided that on the flat side, in particular on the touch-sensitive surface, in an outer region of the control unit, concentric rings or ring sections with respect to the center of the control unit or a, in particular continuous, spiral strip for visualizing files are shown.

[0023] Alternatively, it can be provided that a part of the control unit, including in particular the central region of the upper flat side of the control unit, executes a particularly mechanical rotary movement that is opposite to the direction of rotation of the control unit specified by the record player. In this case, the magnitudes of the sensor-detected angular velocity and the angular velocity of this part of the control unit correspond.

[0024] If appropriate, it can be provided that the media file is represented in the outer region of the control unit at least by a start mark and an end mark as well as an annular or spiral connection between the start mark and the end mark, in particular by a line, a stripe or an annular or spiral graphic.

[0025] If necessary, it can be provided that by touching a point along the connection, playback is continued at a specific playback time within the file, which is determined by the total playback length of the file and the relative distance of the touched point to the start marker and the end marker.

[0026] Optionally, the diameter of the record-shaped control device can be between 15 cm and 35 cm. In particular, the diameter can be equivalent to that of a conventional 7-inch, 10-inch, or 12-inch record. Particularly preferably, the diameter can be 17.5 cm, 25 cm, or 30 cm.

[0027] Optionally, the flat side of the control unit can be provided with a track groove, at least in one ring section concentric with a center point, for receiving a sound track, in particular a continuous tone, that can be picked up by a record needle. This adds the functionality of a continuous tone record, eliminating the need for the user to carry a separate record.

[0028] The invention particularly relates to a method for controlling the playback of digital media files such as audio and / or video files from a database. The method is particularly preferably carried out using a device having one or more of the above-mentioned features.

[0029] The control unit is rotated around its center point, preferably at a constant angular velocity, especially on a record player. The control unit may acquire data on the angular velocity of the rotating control unit via its rotation sensor, for example, gyroscopically. The control unit may acquire inputs such as touches and touch gestures using its at least one control element. The control element is preferably formed by the touch-sensitive surface and the display.

[0030] The touch-sensitive surface and the display preferably form at least one control element that can be actuated by touch or touch gestures, via which

[0031] Playback parameters are generated to control audio or video playback. If necessary, the computer device can generate playback parameters from the inputs, such as start, stop, pause, rewind, or skip commands.

[0032] If necessary, it can be provided that the computer device controls the playback of the digital media file depending on the playback parameters.

[0033] The computer device calculates a media output signal, if appropriate, based on a digital media file. In particular, the generated media output signal is sent to an output device.

[0034] The control unit transmits any determined angular velocity data to the computer. In particular, the control unit transmits data on angular velocity changes and inputs to the computer.

[0035] The computer device may adjust the playback speed of the digital media file depending on the angular velocity of the control unit.

[0036] Optionally, the device's communication device can communicate, in particular wirelessly, with an external device, in particular with an output device. The communication device preferably transmits playback parameters, angular velocity data, and / or audio signals.

[0037] Optionally, the communication device can send media output signals generated by the control unit comprising a computer device to an external device, preferably to an output device. Alternatively, the communication device can send acquired data on the angular velocity and playback parameters to an externally arranged computer device or to an external device comprising a computer device.

[0038] Optionally, a display on the flat side can be provided to display graphic content, such as album covers, and / or form control elements. In particular, the display can be arranged in a central area of ​​the flat side of the control unit and preferably have a touch-sensitive surface.

[0039] Optionally, media files can be visualized on the flat side. This visualization preferably comprises concentric rings or ring sections relative to the center of the control unit or a continuous, spiral-shaped strip. In particular, media files can be visualized on the touch-sensitive surface in an outer area of ​​the control unit.

[0040] Optionally, it can be provided that representations on the flat side, in particular on the display and / or the touch-sensitive surface, particularly preferably representations in the central area of ​​the control unit, execute a particularly virtual rotational movement that is opposite to the direction of rotation of the control unit. The magnitudes of the sensor-detected angular velocity and the angular velocity of the representations preferably correspond.

[0041] Alternatively, it can be provided that a part of the control unit, comprising in particular the central region of the upper flat side of the control unit, executes a particularly mechanical rotary movement that is opposite to the direction of rotation of the control unit specified by the record player. The magnitudes of the sensor-detected angular velocity and the angular velocity of this part of the control unit preferably coincide.

[0042] If appropriate, it can be provided that the media file is represented in the outer region of the control unit at least by a start marker and an end marker as well as an annular or spiral connection between the start marker and the end marker, in particular by a line, a stripe or an annular or spiral graphic.

[0043] If necessary, it can be provided that touching a point along the connection will resume playback at a specific playback point within the file. The playback point can be determined by the total playback length of the file and the relative distance of the touched point from the start marker and the end marker.

[0044] If necessary, it can be provided that the control unit is supplied with power wirelessly and / or via an integrated rechargeable battery and / or via a particularly replaceable battery. In particular, it can be provided that the sensor, the touch-sensitive surface, the display, and / or the communication device are supplied with power wirelessly and / or via an integrated rechargeable battery and / or via a particularly replaceable battery.

[0045] In all embodiments, a recess for receiving the centering pin of a record player can be provided in the control unit. The recess can be a through hole. Alternatively, the recess can be a blind hole if the thickness of the control unit, at least in the central region of the control unit, i.e., at least in the region of the recess, is greater than the length of the centering pin of a conventional record player.

[0046] In addition, different arrangements of the components of the device are conceivable, whereby a rotation sensor, at least one touch-sensitive surface, at least one display and, if appropriate, a communication device are always provided in the base body of the record-shaped control device.

[0047] The database can be installed, for example, in the control unit or in an external device. Furthermore, the database can be a storage medium such as an external hard drive, a USB stick, a memory card such as an SD card, a CD, or a DVD. The database can also be provided as a decentralized service, such as cloud storage or a streaming service.

[0048] The computer device can be provided, for example, as a component of the control unit, as a component of an external device, as an external device or as a component of an output device.

[0049] In all embodiments, touches and touch gestures to be detected can be or include so-called multi-touch operations, in particular tapping, swiping, pressing, holding and combinations thereof with one or more fingers of one hand or both hands.

[0050] In individual embodiments, a central region of the control unit can be provided that is mechanically rotatable relative to the base body. On the one hand, in embodiments with a rotatable central region, the central region can be driven by a motor to compensate for the rotation of the control unit on the record player, so that the central region appears stationary to the user. On the other hand, the rotatable central region can be operated similarly to a jog wheel. This makes it possible, for example, to manipulate the playback of a piece of music. By rotating such a central region, playback parameters such as volume or playback speed can be adjusted, a piece of music can be fast-forwarded and rewound, or a database can be navigated.

[0051] The invention will be further described below with reference to the figures.

[0052] Fig. 1 shows a schematic representation of an embodiment of a device for controlling the playback of digital media files.

[0053] Fig. 2 shows a schematic representation of an embodiment of a control unit in side view.

[0054] Fig. 3 shows a schematic representation of another embodiment of a

[0055] Device for controlling the playback of digital media files.

[0056] Fig. 4 shows a schematic representation of another embodiment of a

[0057] Control unit in side view.

[0058] Fig. 5 shows a schematic representation of a third embodiment of a device for controlling the playback of digital media files. Fig. 6 shows a schematic representation of a third embodiment of a control device in side view.

[0059] Unless otherwise stated, the reference numerals correspond to the following components: 1 control unit, 2 computer device, 3 record player, 4 rotation sensor, 5 flat side, 6 touch-sensitive surface, 7 display, 8 operating element, 9 output device, 10 communication device, 11 external device, 12 ring, 13 start mark, 14 end mark, 15 connection, 16 power supply, 17 database, 18 recess.

[0060] Fig. 1 shows a schematic representation of an embodiment of a device for controlling the playback of digital media files. The device comprises a control unit 1 rotating on a record player 3, an external device 11, and an output device 9. In all embodiments, the control unit 1 can preferably be placed on the turntable of the record player 3, like a conventional record.

[0061] The control unit 1 comprises a record-shaped base body in which a rotation sensor 4, a communication device 10, and a power supply 16 are installed. Furthermore, the control unit 1 comprises a touch-sensitive surface 6 and a display 7 on one of its flat sides 5, namely, in the embodiment of Fig. 1, on the top side.

[0062] A recess 18 is provided at the center of the record-shaped base body, which in the embodiment of Fig. 1 is provided as a through hole. The centering pin can therefore extend through this recess 18 through the control unit 1.

[0063] The touch-sensitive surface 6 and the display 7 form a preferably virtual control element 8. The control unit 1 determines manual inputs via detected touches of the touch-sensitive surface 6. In the embodiment of Fig. 1, the touch-sensitive surface 6 and the display 7 on the upper flat side 5 have an inner, circular area and an outer, ring-shaped area arranged around the inner area. Album covers or music videos, for example, can be displayed on the inner area of ​​the display 7. In addition, the inner area offers the possibility of displaying a control element 8, which can include, for example, virtual start, stop, pause and rewind buttons. Alternatively, the control element 8 can also be displayed in a different area, for example in the outer area of ​​the upper flat side 5.

[0064] In the outer area of ​​the upper flat side 5, concentric rings 12 are preferably displayed, whereby each ring 12 can correspond, for example, to a media file. Alternatively, the rings 12 can run spirally, similar to the grooves of a record. Media files can be represented on these rings 12 by a start marker 13, an end marker 14 and a connection 15 between these two markers. For example, by touching along the connection 15, it is possible to jump to specific points in time within the playback time of the media file. Furthermore, it is also possible to save specific points in time for media files in the form of so-called cue points in order to highlight special points within a media file and make them easier to find later.

[0065] The control unit 1 records data on the angular velocity of the rotating control unit 1 via the rotation sensor 4. The control unit 1 is connected to the external device 11 via a radio link using its communication device 10. The control unit 1 can send data to the external device 11 and vice versa via this radio link.

[0066] The external device 11 preferably comprises a database 17 and a computer device 2. In this embodiment, the external device 11 can be, for example, a PC, the database 17 can be provided, for example, as a storage device, such as preferably a hard disk, in this PC, and the computer device 2 can in particular be the CPU of this PC.

[0067] The computer device 2 generates, on the one hand, data from the media files in the database 17 for displaying information regarding the content of the media files on the control unit 1. On the other hand, the computer device 2 calculates media output signals from the media files, which it then transmits to the output device 9. When calculating the media output signals, the computer device 2 takes into account data on the angular velocity of the control unit 1 and inputs transmitted to it by the control unit 1. The computer device 2 uses the data on the angular velocity of the control unit 1, for example, to adjust the playback speed of the media file and thus the media output signal. This also makes it possible to achieve effects in the media output signal such as those classically created with scratching.

[0068] Fig. 2 shows a schematic representation of another embodiment of a control unit 1 in side view. In this embodiment, the control unit 1 comprises a record-shaped base body in which a computer device 2, a rotation sensor 4, a communication device 10, a power supply 16, and a database 17 are installed. A touch-sensitive surface 6 and a display 7 are provided on the upper flat side 5. In a central region of the control unit 1, a surface raised relative to the flat side 5 is arranged. In the embodiment of Fig. 2, the thickness in this central region is selected such that a recess 18 in the underside for receiving the centering pin of a record player 3 is designed as a blind hole. The centering pin of a record player 3 therefore does not pierce the touch-sensitive surface 6.

[0069] A power supply 16 is provided to supply the control unit 1 and in particular its components comprising a computer device 2, a rotation sensor 4, a communication device 10 and a database 17 with energy.

[0070] The control unit 1 is designed to be operated in a rotational manner on a record player 3. Via the rotation sensor 4, the control unit 1 can acquire data on the angular velocity of the control unit 1. Via the touch-sensitive surface 6, the control unit 1 can acquire inputs via touches and touch gestures.

[0071] The computing device 2 receives data on the angular velocity from the rotation sensor 4 and inputs from the touch-sensitive surface 6. Furthermore, the computing device 2 can access media data in the database 17. The computing device 2 calculates a media output signal from media files. This media output signal is adjusted by the computing device 2, taking into account the angular velocity of the control unit 1 and the inputs. For example, the media output signal is paused, resumed, and the like, based on inputs. Furthermore, the playback speed of the media file in the media output signal is adjusted to the angular velocity of the control unit 1.

[0072] The control device 1 sends the calculated media output signal via a communication device 10, preferably wirelessly, to an external device 11, in particular to an output device 9.

[0073] In an embodiment of the device not shown, the control unit 1 comprises a rotation sensor 4, a touch-sensitive surface 6, and a communication device 10. The computing device 2 is arranged separately from the control unit 1 and accesses a database 17, which is also arranged separately. The computing device 2 receives data on the angular velocity and inputs from the communication device 10 of the control unit 1 and transmits a calculated media output signal to an external device 11, wherein the external device 11 itself is the output device 9 or forwards the media output signal to the output device 9.

[0074] In a further embodiment of the device (not shown), the control unit 1 comprises a rotation sensor 4, a touch-sensitive surface 6, and a communication device 10. The computing device 2 is arranged separately from the control unit 1 and accesses a database 17 that is also arranged separately. The computing device 2 is part of an external device 11 or is itself an external device 11 and receives data on the angular velocity and inputs from the communication device 10 of the control unit 1. The computing device 2 calculates a media output signal from the received data and inputs and forwards this to an external device 11. The output device 9 can be another device or part of the external device 11.

[0075] In a further embodiment of the device (not shown), the control unit 1 comprises a rotation sensor 4, a touch-sensitive surface 6, a communication device 10, and a computer device 2. A database 17 is arranged separately from the control unit 1. Data relating to the angular velocity of the control unit 1 and inputs are transferred to the computer device 2. The computer device 2 accesses media files in the database 17 and forwards a media output signal calculated therefrom via the communication device 10 to an external device 11. The output device 9 can be another device or part of the external device 11. In a further embodiment of the device (not shown), the control unit 1 comprises a rotation sensor 4, a touch-sensitive surface 6, a communication device 10, and a computer device 2. A database 17 is arranged separately from the control unit 1 as part of an external device 11.Data on the angular velocity of the control unit 1 and inputs are transferred to the computer device 2. The computer device 2 accesses media files from the database 17 and returns a media output signal calculated therefrom to the external device 11 via the communication device 10. The output device 9 can be another device or part of the external device 11.

[0076] Fig. 3 and Fig. 4 show a schematic representation of a further embodiment of the control unit 1. It is designed as a pad 20, which has approximately the diameter of a record label and can be placed and operated on a record and on a record player 3, particularly through the centered recess 18. Conventional digital vinyl systems do not offer the user the option of interactively controlling the linked DJ program using the control system located on the record player 3. Although the control unit 1 of the first embodiment offers this option of directly and interactively controlling linked DJ programs using the control system, it is not designed for combination with a so-called Timecode DVS Control Vinyl record, or Timecode Record 19 for short, whose continuous tone is tapped using the record needle 22. The well-known Timecode DVS (Digital Vinyl System) is therefore used here.

[0077] The Touchscreen Control Vinyl DVS doesn't offer the user experience of a real vinyl record. The Pad 20 allows you to take advantage of the benefits of both systems.

[0078] Conventional DVS Timecode Control vinyl records 19 have a continuous tone recorded on them, which is read by the record needle 22 of a record player 3 and sent to a computer, possibly in combination with appropriate hardware between the record player 3 and the computer. A DJ program on the computer analyzes the pitch of this continuous tone and uses this to derive the rotation speed of the timecode record 19 on the record player 3. Subsequently, an audio file on the computer in a DJ program can be played faster or slower or the playback direction can be controlled accordingly. The control unit 1 no longer works by evaluating a continuous tone, but rather using sensors. It is a small, battery-operated, wireless device that is placed or glued onto a record and uses internal sensors to detect the position and movement on the record player 3.This sensor information is sent wirelessly and in real time to the computer, possibly in combination with appropriate hardware between turntable 3 and the computer, and thus an audio file on the computer can be played faster or slower in a DJ program, or the playback direction can be controlled.

[0079] Pad 20 is a battery-operated, circular touchscreen with a diameter of approximately 10 cm. It is placed, glued, or otherwise connected, preferably centered on a conventional DVS Timecode Control vinyl record 19 (or any other record). The continuous tone range on the connected timecode record is not affected or only slightly affected, and the original timecode DVS functions of the timecode record 19 are retained. It is placed on a turntable 3 together with the timecode record. It is intended for use in combination with timecode DVS records 19.

[0080] Pad 20 is wirelessly connected to the same computer 25 and DJ program to which the timecode record 19 is connected. While the timecode record serves as a DVS in combination with the record needle 22 of the turntable 3 to control the playback of an audio file on the computer and in the DJ program, pad 20 simultaneously provides access to various other functions of the DJ program.

[0081] The pad 20 receives song and playback information as well as control parameters from the computer and displays them in the form of control elements or images. For example, the cover of the song being played, the remaining playback time, song name, playback position, etc. can be displayed. At the same time, the pad 20 sends information about the touch inputs made on the touchscreen of the pad 20 on the displayed control elements to the computer, which processes this information. The pad 20 is thus able to display song information and control elements and make them selectable and controllable on its touchscreen. This allows the visualization 32 of playback parameters and song information and thus at least the rudimentary control of the DJ program. The connected timecode record 19 is played simultaneously on the turntable 3 and is also responsible for the conventional DVS functions of the DJ program.The pad 20 has a circular touchscreen which is able to display, among other things, the cover art or information etc. of the audio file being played. Controls can also be displayed on the touchscreen which represent individual songs in a playlist, particularly as circles with a start and end point. Tapping these controls starts their playback. Likewise, tapping one of these controls can display the corresponding song in its entirety as the entire waveform 23 of the song, allowing a more precise, step-by-step listening experience by tapping along the waveform 23 or line displayed on the touchscreen. It is also possible to display and select CUE points in the song and touching these CUE points would, for example, start the song playing instantly at that point.

[0082] In addition to direct touch inputs or multi-touch inputs on Pad 20, swiping movements on Pad 20 can be used to trigger commands such as "Next >" and "Previous <" in the DJ program. Another feature of Pad 20 is that its own rotation on the turntable 3 can be visually paused or slowed down by counter-rotating the displayed image. This allows a static screen to be displayed if required, thus providing more precise / extended operation of the displayed controls. Pad 20 thus offers users of Timecode DVS Schallplatten 19 expanded display and control options when combined with a Timecode Vinyl Schallplatten 19.

[0083] Since it does not fill the entire record and is primarily intended to lie only in the inner cover area of ​​the timecode record 19, the functions and advantages of timecode records 19 are retained, as is the haptic and precise feeling of a resting record player needle 22 that picks up the continuous tone of the timecode record. However, the pad 20 can also have a diameter larger or smaller than 10 cm - the continuous tone track grooves 21 of the connected timecode record 19 must, however, remain usable in any size configuration. Compared to control unit 1, the pad 20 is smaller as a whole record and is intended for the inner area of ​​the connected record, in particular the area of ​​the record label, and it is intended for combination with timecode record 19.

[0084] The pad 20 has approximately the diameter of a record label, i.e., approximately 10 cm, or a different diameter. The height of the pad 20 depends on technical feasibility and the technical features it incorporates. However, the height should preferably be kept as low as possible. In the center of the pad 20 is a recess 18, which can also be designed as a through-hole, for receiving a record player centering pin. In any case, the top of the pad 20 features a touchscreen surface that can function as a display and receive touch inputs from the user.

[0085] The pad 20 is wirelessly connected to the computer and can receive information such as touch inputs on the surface from it, as well as send information to it. The pad 20 has a battery or rechargeable battery. If the DVS timecode record 19 connected to the pad 20 shows signs of wear, it can be easily replaced with a new one. The pad 20 may also have its own processing unit as well as sensors for detecting the position and movement of the turntable 3. The pad 20 can also be used with playback devices, provided they support the functional principle of the pad 20. The pad 20 may not be directly connected wirelessly to the computer 25, but an intermediate device may also be used to control the wireless transmission 26.

[0086] The pad 20 can, under certain circumstances, also be used without being connected to a record. The functions of the pad 20 described above can be implemented in combination with a timecode record 19, even if it does not have any sensors of its own. If the pad 20 does not have any sensors for detecting movement, the timecode record connected to the pad 20 can serve the computer 25 as a timer for the displays that it sends to the pad 20, e.g., regarding the current playback position in the currently playing song. In combination with a timecode record, the pad 20 does not necessarily require sensory movement detection to fulfill the described functions, but may require sensory position detection in order to be able to align displays optically and not position the displayed objects arbitrarily, e.g.to always align the playback position or the starting point of a visualization 32 of a song in the direction of the record needle 22.

[0087] However, if the pad 20 is specifically equipped with sensors for position and movement detection, in addition to the functions described, it can also be used in combination with timecode records 19 as a sensory DVS system, similar to the MWM Phase DVS. This allows the user to dispense with the turntable needle 22 or the connected timecode record, if necessary, and, for example, to continue the DVS functions of the timecode record once it has reached its end. It can then also be used / connected to normal records. As a sensory DVS device, the pad 20 offers novel features compared to the MWM Phase DVS due to the display and control options of the touchscreen. The functions of the pad 20 thus exceed those of the exclusively sensory MWM Phase DVS.

[0088] Fig. 5 and Fig. 6 show a schematic representation of a third embodiment of the control unit 1 in the form of a “DJ Control-Vinyl Multi DVS”, or Multi DVS 30 for short. It is a DVS control unit 1 that combines the functionality of conventional timecode DVS with the functionality of the control unit 1 in order to expand their functions and user experience.

[0089] Although Pad 20 allows you to use the advantages of both systems (Timecode DVS and Touchscreen Control Vinyl DVS), it is designed to be used in combination with a normal Timecode record 19 and is therefore limited in size. Most of the available space on a maximum 12" record is reserved for the Timecode track grooves 21 of the Timecode record 19 combined with Pad 20. Pad 20 is therefore specifically designed for the inner area of ​​a 12" record and, like a record label, only has a diameter of around 10 cm. Due to its size, Pad 20 only offers a reduced touchscreen area and, accordingly, only reduced display and control options for the DJ software on the computer 25.

[0090] The Multi DVS 30 offers a controllable touchscreen surface across the entire size of a record (max. 12"), just like the Touchscreen Control Vinyl DVS, but also conventional timecode DVS continuous tone grooves 21 on this touchscreen surface, which can be read by a record player needle 22. The size and position of these timecode DVS continuous tone grooves 21 on the touchscreen surface of the Multi DVS 30 preferably correspond to those of a conventional 12" timecode record 19, but can also be larger or smaller.

[0091] All the DVS systems mentioned so far can be used with computers as well as other playback devices or DJ control devices (e.g. DJ controllers) that are designed for them and support their functions - also preferably the Multi DVS 30.

[0092] The Multi DVS 30 version adds innovative functionality to existing DVS systems by combining Touchscreen Control Vinyl DVS and Timecode DVS. It allows the use of its touchscreen interface to display and control DJ software, just like the Touchscreen Control Vinyl DVS, while simultaneously playing Timecode DVS continuous tone track grooves located on its surface with the record player's stylus 22, which can be used to control the same DJ software if necessary. The Multi DVS 30 is therefore designed like the Touchscreen Control Vinyl DVS and has the same functions and features.

[0093] The surface of the Multi DVS 30 touchscreen monitor is not simply that of a conventional touchscreen, but is specially prepared. The surface has, at least in one area 31, the same continuous tone grooves 21 as those found on timecode records 19. The DJ Control Vinyl Multi DVS can therefore be played like a conventional timecode record with the record needle 22 on a rotating record player 3, and can thus fulfill the functions of conventional timecode records 19. The DVS grooves 21 are applied to the surface in the non-central area 31 or incorporated into it in such a way that they do not impede the functions of the touchscreen—neither the display nor the ability to make touch inputs. This can be done, for example, in the form of an adhesive, grooved film that does not impair the function of the touch-sensitive surface 3 underneath. Solutions for this include, for example,from the smartphone area.

[0094] If these track grooves 21, especially depending on the material of this special touchscreen surface, can show signs of wear through use and reading with record needles 22, it is possible to replace the touchscreen surface with the Timecode DVS track grooves 21 of the Multi DVS 30 without having to replace the entire Multi DVS 30 system - e.g. similar to replacing a broken smartphone screen.

[0095] The Multi DVS 30 is preferably connected wirelessly to the same computer 25 and DJ program as the turntable 3, whose stylus 22 reads the timecode track grooves 21 of the Multi DVS 30 surface. Whether the connected DJ software on the computer 25 uses the sensory DVS information from the Multi DVS 30 to control DVS playback or the timecode DVS information generated by the stylus 22 scanning the surface of the Multi DVS 30 to control DVS playback depends on the application and can be combined. Due to its sensory DVS functions, the Multi DVS 30 can also be used without a stylus 22.As long as the user does not place the record needle 22 on the surface of the rotating Multi DVS 30, the Multi DVS 30 can assume all conventional functions of the Touchscreen Control Vinyl DVS and thus also offers the sensory DVS functions of the Touchscreen Control Vinyl DVS, which does not rely on timecode DVS.

[0096] While these timecode DVS track grooves 21 on the Multi DVS 30 in combination with the record needle 22 of the record player 3 can be used for DVS control of the playback of an audio file on the computer 25 and in the DJ program, the remaining surface of the Multi DVS 30 not used by the record needle 22 of the record player 3 simultaneously offers the same functions and features as the Touchscreen Control Vinyl DVS and so, for example, viewing and accessing various functions of the DJ program via touch inputs.

[0097] The Multi DVS 30, similar to the Touchscreen Control Vinyl DVS, can receive, among other things, song and playback information as well as control parameters from the computer 25 and display them in the form of controls or images. This allows the display of the cover of the playing song, the remaining playback time, the song name, the playback position, song visualizations 32, the start and end point markers 13, 14 of the playing song, etc.

[0098] At the same time, the Multi DVS 30, similar to the Touchscreen Control Vinyl DVS, wirelessly transmits information about the touch inputs made on its touchscreen to the displayed control elements to the computer 25, which processes them. Like the Touchscreen Control Vinyl DVS, the Multi DVS 30 features sensory DVS functions. However, the timecode DVS track grooves 21 on the touchscreen surface of the Multi DVS 30 can be played simultaneously on the rotating turntable 3 with the record needle 22, allowing the read-out timecode information to be used simultaneously or preferably for the conventional DVS control functions of the DJ program (playing an audio file faster or slower in a DJ program, or controlling the playback direction).

[0099] The Multi DVS 30 is thus designed for the possible, but not necessary, combination of Touchscreen Control Vinyl DVS with Timecode DVS. If the record needle 22 is placed on the rotating Multi DVS 30, the computer 25 can decide, depending on the need or application, whether the wirelessly transmitted DVS sensor data from the Multi DVS 30 or the DVS timecode information read from the record needle 22 and the surface of the Multi DVS 30 and transmitted to the computer should be used to control displays on the Multi DVS 30 or the playback of the file on the computer 25.

[0100] The Multi DVS 30 has, first and foremost, all the functions of the Touchscreen Control Vinyl DVS, but thanks to its special surface which has Timecode DVS continuous tone track grooves 21, it is capable of being played with a turntable needle like a normal record. Therefore, even when switched off, it would function and be able to serve like a conventional Timecode record 19, as it has corresponding DVS continuous tone track grooves 21. However, it is particularly designed for combination of conventional Timecode DVS and the Touchscreen Control Vinyl DVS. However, since the Touchscreen Control Vinyl DVS already has all the necessary DVS functions thanks to its sensors, this combination is not necessary but should be viewed as an optional extension to offer users the experience and special features of conventional Timecode DVS via record needles when required.

[0101] If, in an alternative version, the Multi DVS 30 does not have the appropriate sensors to provide DVS functions, the timecode DVS track grooves on its surface or the playback of these with the record needle 22 could be used as a supplement to compensate for the lack of DVS sensors.

[0102] The Multi DVS 30 offers users the DVS functions and the expanded display and control options of Touchscreen Control Vinyl DVS, but if necessary also the ability to play with record needles on turntables 3 and thus DVS as with a timecode record 19, especially in combination with the functions and functionality of Touchscreen Control Vinyl DVS. Thus, the Multi DVS 30 retains the functions and advantages of Timecode Records 19 and the tactile and precise feel of a resting turntable needle 22 picking up the continuous tone of the Timecode Record 19.

[0103] This combination of touchscreen record 19 and timecode DVS is the core of the Multi DVS 30 embodiment and the difference to the pad 20 and other embodiments of the control unit 1 - which is not intended for combination with timecode DVS, but is primarily intended as a standalone device, preferably in the size of 7" up to the size of a whole 12" vinyl record and consists entirely of touchscreens, works with sensors and does not provide for the use of the record player needle 22, since its surface does not have timecode DVS track grooves 21 that can be tapped by a record player needle 22.Although the Multi DVS 30 is equipped with all the features of the Touchscreen Control Vinyl DVS and is therefore not dependent on the use of Timecode DVS, it offers a new feature, a combination with Timecode DVS via the record needle 22 due to its special surface (Timecode track grooves), which can be processed accordingly on the computer 25.

[0104] The wireless signal transmission 26 between the Multi DVS 30 and the computer 25 occurs directly, or an intermediate device is used to control or provide the wireless transmission. The wired DVS timecode signal transmission 24 from the turntable 3 to the computer 25 can occur via an intermediate device, as is usual with timecode, or in a direct connection between the computer and the turntable 3. The Multi DVS 30 can be designed for use with computers, but also particularly for use with special digital audio (and video) players, provided they support DVS and, in particular, the extended functions of the Multi DVS 30. The Multi DVS 30 can also be combined with DJ controllers and other DJ playback devices and DJ control devices, provided they support the functions of the Multi DVS 30.
