1. Field of the Invention
The invention relates generally to equipment for playback and control of multimedia. More specifically, the present invention relates to disc jockey mixing equipment for control of the playback of multimedia files, such as audio and video files.
2. Background of the Related Art
In the music industry, there is a need for a person, such as a disc jockey, to be able to playback multimedia with control and precision. Such multimedia is available in many different forms. For example, it has been well known for many years that audio is available on analog vinyl discs. In particular, music recordings have been available on vinyl records and have been widely played by disc jockeys on turntables during a playback performance.
However, there is typically a need and desire to provide continuous music playback during a disc jockey performance. To carry this out, two or more turntables have been commonly employed whereby one turntable plays the current selection of music while the second turntable is used to cue up the next selection. When the first selection of music is nearing its end point or is at its end point, playback to the second turntable can be switched to the second turntable without interruption of the master output. It is also very well known that the transition from one turntable to another can be mixed or faded back and forth for seamless transition from one music selection to another. This back and forth transition and mixing can be carried out back and forth indefinitely during a disc jockey performance.
To carry out this mixing, a disc jockey mixing device is typically employed. The mixer commonly includes two inputs, one for each music source, such as a turntable, and a master output. A control interface is provided on the mixer so that the disc jockey can intuitively control the mixing and output of the media sources. This interface is critical so that the disc jockey can effectively control such mixing and playback output of the media for an engaging performance.
When turntables and vinyl records are used as the source for audio as the media, the cueing and playback of the audio are dictated by the turntable itself. The disc jockey must physically place the vinyl record on the turntable, place the needle on the desired spot and cue it up for playback when desired. When it is time for that selection to be outputted for playback, the mixer is manipulated to switch or fade to that selection so that it can be heard at the master output. When the selection is no longer desired, the turntable is the stopped by actuating the appropriate button or control on the turntable itself.
In general, the controls on the turntable itself are used to control playback and command operation of the turntable. As a result, disc jockey turntables provided with controls that are particularly well-suited for fast and easy control of a vinyl record. For example, play and cue buttons are typically very large and easily accessible, which is essential in a dark night club and where selection changes are frequent.
Vinyl records played back by turntables are a well known source of media for playback by a disc jockey, recently, there have been many new forms of digital media that are suitable for use by a disc jockey. For example, digital compact discs (CDs) are now a common storage format for media, such as digital audio. The digital audio is stored on an optical CD. Turntables are commonly substituted by compact disc players and mixed, as described above. Control of transport and operation of a CD and the audio files thereon can be carried out easily by providing disc jockey friendly operation controls thereon. For example, the playback/cue button can be large and intuitively placed on the CD player to facilitate the disc jockey performance.
In similar fashion to CDs, which store digital files on a optical disc, other storage media have been employed to store digital audio file for easy playback. For example, digital audio files can be stored on hard disks, memory RAM cards, USB thumb drives, and the like. These storage devices can also serve as the source of media files for later playback and mixing by a disc jockey. These storage devices can be separate units that serve as input sources for a disc jockey mixer, as an alternative media source for an analog turntable or CD player. For example, media players with hard disks and/or memory card slots for receipt of removable media are well known in the art. As with turntables and CD players, these are units that are provided with large and intuitive controls for playback and command of the media files. These controls are commonly specifically laid out and arranged for disc jockeys to facilitate their disc jockey performance.
It is also known in the art that CD players, hard disk players can be integrated with a disc jockey mixer for a single device solution. However, these units are still large enough and configured by design for use by disc jockeys.
Recently, portable media devices have become very popular for their compact size, large storage capacity and dropping cost. Portable media devices are available in the form of portable hard disk drives and, in particular, portable media players. These portable media players can playback audio files in many different formats, such as “mp3” and “wmv”. Also, many of these players can playback video files in different formats, such as “avi” and “divx”. For example, portable media players manufactured by Creative Technology Ltd., Apple Computer, Inc. and Archos, Inc. are widely sold with this capability.
These players typically include their own operating system and transport and command controls on the devices themselves so the user can playback and control files when desired. These portable devices are, essentially, personal players in that they are typically meant to be held in the hand or hands of the user so that the user can manipulate the controls for playback through headphones or a stereo system, for example.
While these transport and command controls are suitable for most uses of the portable players, there is often a need to enhance or improve the control of the personal player or connected mass storage class device for other uses. For example, remote controls have been provided for portable media players. A receiver is connected to the portable player that is interconnected with the operating system of the player. A wireless remote that uses infrared, for example, includes a duplication of some or all of the transport and command controls of the actual device. Pressing a button on the remote transmits commands to the receiver to thereby control operation of the portable player. Such a wireless remote is well suited for operating a portable player from a distance without having to touch the player itself.
Many portable devices include their transport and command controls on the front face of the player. If the player is in a case without only its top edge exposed, the entire player must be removed so that the controls can be manipulated. To address this problem, there are prior art control modules that can be plugged into the edge of a players, such through it headphone jack which commonly includes additional contacts for access to the players operating system.
Alternatively, some of the transport and command controls can be duplicated on a tethered connection to the player, such as inline with the headphones. Due to the small size that is feasible on a small tethered control, only the primary transport and command controls are provided thereon.
In the prior art, it has also been known to provide a dock for receipt of the portable player therein where some of the controls are repeated on the dock to facilitate use. For example, many stand alone powered speaker units that include a dock for a portable media player have such duplicated controls for use to obviate the user to manipulate the controls on the player itself.
While the controls on a portable players are sufficient for a person to manipulate while in their hand, these controls are not well suited for use by a disc jockey during a performance. Moreover, duplicated transport and command controls for a portable media player, such as those on tethered remotes, plug-in modules and powered speakers are inadequate for use by disc jockeys. They are not laid out in an intuitive or logical fashion for use by a disc jockey. Moreover, none of them provide mixing capabilities between more than one portable player. Also, none of them can stream and mix audio from the same or two different portable media devices. Further, none of the prior devices provide a way to mount the portable media player so its screen can be easily viewed in connection with its respective player controls. The prior art is also devoid of a device that has two separate dedicated sets of disc jockey style controls for each portable players.
In view of the foregoing, there is a demand for a digital mixing controller that can interconnect to portable media devices, such as mass storage devices, such as external hard drives and portable media players which have storage therein. There is a demand for a digital mixing controller apparatus for portable media devices that includes controls for command of operation of devices connected to the apparatus. There is another demand for an apparatus for portable media devices that can mix media streamed from one or more media devices connected thereto. There is a demand for a digital mixing apparatus that can control and command media stored on a connected mass storage device. There is yet another demand for an apparatus for portable media devices that displays media information thereon. There is a demand for an apparatus for portable media devices that can fully control the media thereon directly without having to access and control the operating system of the media device if it is a portable media player.
The media player of the present invention preserves the advantages of prior art mixers and controllers portable media storage devices including portable media players. In addition, it provides new advantages not found in currently available devices and overcomes many disadvantages of such currently available devices.
The media player is generally directed to the novel and unique digital mixing controller apparatus for playing and controlling media, such as audio and video files, stored on an attached media storage device to the apparatus of the present invention.
The media player includes a new and unique digital mixing controller that provides not only a control interface for controlling and commanding media on a first portable media storage device but also provides its own unique operating system for directly controlling the media. Therefore, the connected media storage devices merely need to operate as a mass storage device where the apparatus can gain access to the files thereon. The apparatus of the present invention preferably does not access or use the media playback and operating system located on the device itself. The devices can be, for example, a portable external USB hard drive or portable media player with audio and/or video files thereon.
The apparatus includes a preferably rack-mountable housing with two sets of media controls thereon. The portable media storage devices are connected to the apparatus by USB ports or other known file transfer methodologies, such as IEEE-1394 and Bluetooth. A microcontroller resides in the housing and handles processing of media files. The first media controls and the second media controls are electrically interconnected to the microcontroller. One or more portable media storage devices with media items thereon are connected to the apparatus. As a result, the apparatus will have access to all of the media located on any of the connected storage devices.
The user interface is very flexible where tracks can be flagged, selected and grouped into playlists (or cue sets) for later playback and control. As a media item in the playlist next up for playback, it can be automatically sent to one side (i.e. A or B) or the other for control by the appropriate disc jockey interface controls located on the front of the apparatus. Thus, the disc jockey will not required to manually cue playback of a given file on a specific side. The apparatus can automatically control this which is a new and unique feature. Alternatively, a given media file may be manually placed on one side or the other for control by a given set of controls.
Manipulation of the first set of controls and second set of controls on the apparatus respectively commands operation of media items that have been assigned to it. Outputs connected to the portable media storage devices can be mixed and fully controlled in a disc jockey fashion. The levels of each side and master volume of the mixed outputs of the can be controlled.
These and other features, aspects, and advantages of the embodiments of the media player of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings where:
Referring now to
The media player 10 includes a digital mixing controller that provides not only a control interface for controlling and commanding media on a first portable media storage device but also provides its own unique operating system for directly controlling the media. Therefore, the connected media storage devices merely need to operate as a mass storage device where the apparatus can gain access to the files thereon. The apparatus of the present invention preferably does not access or use the media playback and operating system located on the device itself. The devices can be, for example, a portable external USB hard drive or portable media player with audio and/or video files thereon.
Referring to
The front face can be divided roughly into three control areas, a first interface to a first deck, a second interface to a second deck, and a central control interface. The first and second interfaces are identical in operation, but permit a disc jockey to cue, beat match, and play media independently on each corresponding deck. The central control interface includes global controls and the main display screen for both decks.
Located prominently in roughly the center of the each interface is a jog wheel control 20a, 20b. The jog wheel control 20a, 20b can be used for pitch bending, scratching and searching through the music playing on the respective deck. The functionality of the jog wheel control 20a, 20b is determined by the accompanying scratch control 22a, 22b and search control 24a, 24b.
While a media track is playing on the respective deck, the jog wheel control 20a, 20b functions as a pitch bend. Pitch bending temporarily speeds up (turn clockwise) or slows down (turn counter-clockwise) the media. This technique is used when to adjust two beat-matched tracks that may not be completely synchronized. Hence, with pitch bending a disc jockey can temporarily slow down or speed up the track that is being mixed so its beats are synchronous with the beats of the other track that is already playing on the other deck.
While a media track is paused, a disc jockey can use the jog wheel control 20a, 20b to seek through the music to a new cue point location. Activating the respective play/stutter control 26a, 26b following the adjustment of the jog wheel control 20a, 20b sets the cue point at the new selected location.
A scratch control 22a, 22b is provided adjacent to each respective jog wheel control 20a, 20b to engage scratch mode. In scratch mode, the jog wheel control 20a, 20b allows a disc jockey to apply a scratch-effect to the media track in much the same way that disc jockeys scratch a vinyl record. As the media track is playing, shifting the jog wheel control 20a 20b back and forth creates a scratching effect. When the jog wheel control 20a, 20b is held stationary, normal playback of the media track resumes. To resume play with no gap in the audio, “push off” by scratching forward at approximately normal playback speed before releasing the jog wheel control 20a, 20b.
Also adjacent to each jog wheel control 20a, 20b is a respective search control 24a, 24b to engage search mode. Search mode allows the disc jockey to use the jog wheel control 20a, 20b to quickly scan through the current media track. If the disc jockey does not touch the jog wheel control 20a, 20b for a short period (approximately eight seconds) the respective deck automatically exits search mode.
A play/stutter control 26a, 26b is included on each respective deck. Activating the play/stutter control 26a, 26b starts the currently selected in the deck. A cue point is set at the current position and the media begins playing. Activating the play/stutter control 26a, 26b while the media player 10 is playing restarts the media from the cue point, which can be used to create a “stutter” effect.
Adjacent to each play/stutter control 26a, 26b is a pause control 28a, 28b. The pause control 28a, 28b stops the media track playing on the corresponding deck. Activating and holding the pause control 28a, 28b for approximately one second while paused, returns the playback of the media to the beginning of the selected track.
Adjacent to each pause control 28a, 28b is a cue control 30a, 30b. The cue control 30a, 30b returns and simultaneously pauses the media at the last set cue point. As described earlier, a cue point is the last place where play/stutter control 26a, 26b was activated or the start of the track, if the play/stutter control 26a, 26b has not been activated. By activating and holding the cue control 30a, 30b, the respective deck of the media player 10 will begin playing the selected media track for as long as the cue control 30a, 30b is held active. Once the cue control 30a, 30b is released, the media player 10 will jump back and pause at the cue point.
A cue point can be easily edited by spinning the jog wheel control 20a, 20b to a new position while paused. As the disc jockey spins the jog wheel control 20a, 20b, the media track will sound. By stopping the jog wheel control 20a, 20b and activating the play/stutter control 26a, 26b, a new cue point is set.
Each deck includes a pitch slider control 32a, 32b, which is used to control the speed (or pitch) of the media track. Moving the slider toward “−” results in a lower pitch (and slower tempo) of the media track, while moving the slider toward “+” results in a higher pitch (and faster tempo) of the media track.
Working in conjunction with each pitch slider control 32a, 32b is a pitch adjustment control 34a, 34b. The pitch adjustment control 34a, 34b adjusts the range (or precision) of control the pitch slider control 32a, 32b has on the overall tempo of media trck. Activating the pitch adjustment control cycles through pitch ranges of ±0, 6, 12, 25, and +25/−100%, although other ranges could be used. Selecting 0 will deactivates the pitch slider control 32a, 32b.
Different pitch ranges allow for different precision over the speed of the media track. Selecting a smaller pitch range, such as ±6%, allows the disc jockey to have more precise control over the speed of the media track. Selecting a larger pitch range, such as +25/−100%, allows for more extreme speed adjustments and can be used for interesting special effects.
The media player 10 includes a beat keeper that automatically tracks beats based upon a combination of frequencies and rhythm patterns in the media currently playing. It shows beats per minute (“BPM”) in a beat display 36 and outputs 4-count (i.e. one measure) information about the media track in a marching bar graph. The beat display 36 includes a left bar 38, a right bar 40 and a middle bar 42. The left bar 38 represents the beat of the media playing on the first deck, while the right bar 40 represents the beat of the media playing on the second deck. The middle bar 42 indicates when the downbeats of the media playing on both decks occur simultaneously in order to aid the disc jockey in beat matching two different tracks of media.
A tap control 44a, 44b is provided adjacent to the search control 24a, 24b on each deck. Activating the respective tap control 44a, 44b in time with the beat of the media currently playing will aid the beat keeper in detecting the proper tempo. Activating and holding active the tap control 44a, 44b for approximately one second resets the beat keeper and causes it to recalculate the BPM.
A mode control 46a, 46b is also provided on each interface. Activating the mode control 46a, 46b invokes a menu on the main display screen 56 that includes deck options, such as pitch range, time display and fader start. The disc jockey can subsequently use the select knob 48, described in detail below, to dial in the desired values and pressing down on the select knob 48 will move on to the next option. Activating the mode control 44a, 44b again exits the deck options menu.
Each interface also includes a set of loop controls. In particular, there is a loop in control 50a, 50b, a loop out control 52a, 52b, and a re-loop control 54a, 54b.
The loop in control 50a, 50b is used to set a “loop in” point in the media track. By default, a “loop in” point is automatically set to the current cue point (which defaults to the beginning of the track). A new “loop in” point is defined by activating the loop in control 50a, 50b when the media track reaches the desired point. A loop in indicator within the loop in control 50a, 50b will light, indicating a new “loop in” point has been set. A new loop in point can be set by merely activating the loop in control 50a, 50b again at the new desired location within the media track.
The loop in control 50a, 50b can also be used to create a new cue point. Activating the loop in control 50a, 50b sets a cue point will be set at that location also. The disc jockey can return to this new cue point by activating and holding cue control 30a, 30b while simultaneously activating the loop in control 50a, 50b. The deck will pause and return to the loop in point. Playback can be resumed by subsequently activating the play/stutter control 26a, 26b.
The loop out control 52a, 52b is used to set the end point of the loop. The first time the loop out control 52a, 52b is activated while a media track is playing, an indicator in the loop out control 52a, 52b will blink and the media track will begin playing in a seamless loop starting from the “loop in” point and ending at the “loop out” point. To release or end the loop, the loop out control 52a, 52b is activated a second time. Play continues forward when the media track passes the previously set loop out point. The indicator in the loop out control 52a, 52b will continuously light, indicating that the loop is now stored in memory for re-looping purposes later.
Like the loop in control 50a, 50b, the loop out control 52a, 52b can also be used to create a new cue point. Activating the loop out control 52a, 52b sets a cue point at that location also. The disc jockey can return to this new cue point by activating and holding cue control 30a, 30b while simultaneously activating the loop out control 52a, 52b. The deck will pause and return to the loop out point. Playback can be resumed by subsequently activating the play/stutter control 26a, 26b.
The re-loop control 54a, 54b repeats play of the media track from the loop in point. If a loop has been set, it plays and repeats a previously set loop, until it is released by activating the loop out control 52a, 52b. By activating the re-loop control 54a, 54b repeatedly, a stutter effect can be made.
The central control interface contains the global controls for the media player, such as navigation and function controls, as well as the beat keeper display 36 and the main display screen 56. The main display screen 56 displays information about the media player, the decks and any attached peripheral devices, such as removable hard discs or portable media playing devices.
Adjacent to the main display screen 56 is a menu select knob 48. The menu select knob 48 is used to navigate lists, change settings, and operate various parts of the user interface. The menu select knob 48 can be rotated and pressed to select or change a highlighted item within the user interface menus displayed on the main display screen 56.
Also adjacent to the main display screen 56 is a display contrast control 58. The display contrast control 58 is used to increase or decrease the contrast of the main display screen 56 to enable viewing under various lighting conditions.
Below the display contrast control 58 is a library selection control 60. The library selected control 60 allows the disc jockey to access the library of media stored on removable media connected to the media player through one of the USB ports 18, 84.
Below the library selection control 60 is a crate control 62. The crate control 62 allows the disc jockey to view the media tracks that have been labeled as being in the crate (or flag list). While viewing media tracks in the crate (or flag list), the disc jockey can use the multifunction controls 70, 72, 74, 76, 78 below the main display screen 56 to send tracks to either deck for mixing, pull them back into the crate for later use if they are already playing, or remove them from the crate altogether. The disc jockey may also switch the media track order in the crate, by using the selected knob 48.
On the opposite side of the main display screen 56 and below the select knob 48 is an eject control 64. Activating the eject control 64 enables the disc jockey to select a mass storage device connected to the media player 10 to dismount. When the eject control 64 is activated, a list of the devices currently attached to the media player 10 is displayed on the main display screen 56. The disc jockey uses the select knob 48 to select the desired device to be ejected.
Below the eject control 64 is a utility control 66. Activating the utility control 66 invokes a utility menu to display on the main display 56. In the utility menu, the disc jockey can adjust display preferences, restore settings to their factory default state and calibrate the pitch sliders 32a, 32b.
Below the utility control 66 is a view control 68. The view control 68 is used to access different information about the media playing on either of the decks. The view control 68 also toggles between track information and a track profile view of the media track playing.
A track profile is a visual representation of a media track, designed for quick and easy identification of phrases or segments within that media track, differentiated by their “energy”. Distinct from a waveform, a profile doesn't show every small detail of the track, just the big changes in terms of energy.
The track profile is split into three shades of grey, with black making up the total number of variations to four. The white portions of the track indicate high energy and volume, graduating down to the black sections representing quieter phrases. The length of each profile is scaled to exactly fit the available work area on the main display screen 56, so the entire track is always visible.
Four multifunction controls 72, 74, 76, 78 are found below the main display screen. The four multifunction controls 72, 74, 76, 78 are used to select from available menu items displayed on the on the main display screen 56. Depending on the menu that is being viewed, the functionality of the individual multifunction controls 72, 74, 76, 78 will change. The main display screen 56 will display one or more icons directly above each multifunction controls 72, 74, 76, 78 indicating the function of each particular multifunction control 72, 74, 76, 78, respectively.
On either side of the four multifunction controls 72, 74, 76, 78 are a left page control 80 and right page control 82. The left page control 80 and the right page control 82 are used to scroll through available pages of selections, when available. If there are additional pages to be viewed, a left or right arrow icon is displayed on the display screen above the left or right page controls 80, 82, respectively. The left page control 80 and the right page control 82 are also used to move a cursor 96 when entering text in the main display screen 56.
Referring now to
The USB ports 84 can be used to attach mass storage devices to the media player 10 and other USB compatible devices. For instance a USB compatible keyboard can be attached to permit text entry in the media player 10 rather than using the select knob 48 and left and right page controls 80, 82. The two available USB ports 84 may be expanded through use of an optional USB hub.
The media player 10 includes two line output ports 86a, 86b. The first line output port 86a is configured as an RCA connection and outputs the audio signal from the first deck. The second line output 86b port is also configured as an RCA connection and outputs the audio signal from the second deck. The two line outputs 86a, 86b and be attached to a separate mixing console and transmitted to speakers for the audience.
The media player 10 also includes fader start connectors 88a, 88b. The fader start connectors 88a, 88b may be connected to a fader-start compatible mixer. Fader start allows a disc jockey to remotely start playback on either deck of the media player from a fader-start compatible mixer. With this feature, every time a disc jockey moves a crossfader control on a fader-start compatible mixer from one input to the other, the track loaded on that respective deck begins to play.
The media player 10 is capable of playing media files stored in popular formats, such as MP3, WAV and AAC music formats. Moreover, the media player 10 is capable of reading and controlling file systems stored in FAT16, FAT32, NTFS (read-only) and HFS+ formats. The media player 10 directly controls devices in these formats rather than working through the device itself or a proxy. This feature allows the media player 10 to be responsive and avoids latency and compatibility problems.
Turning now to
Pressing either the crate control 62 or the library control 60 invokes a select menu that is displayed on the lower portion 94 of the main display screen 56 shown in
If the disc jockey desires to search for a particular album, the disc jockey uses the select knob 48 to move the cursor 96 to highlight the search selection on the menu 94 and presses the select knob 48 as shown in
Referring to
If the disc jockey desires to cue more media tracks to play, he merely activates the library control 60 or crate control 62 to return the main menu 56 as shown in
Referring to
Referring to
Media tracks may also be searched for and selected by song title, recently played and playlist also. Through use of the select knob 48 and multifunction controls 72, 74, 76, 78, playlists may be created and media tracks added thereto.
Therefore, it can be seen that the media player of the present invention provides a unique solution to the problem of providing an apparatus for a disc jockey that includes a unique graphical user interface to enable a disc jockey to manage external libraries of media tracks, yet still includes dual decks and dual sets of disc jockey specific controls that disc jockeys need during performances. The media player of the present invention enables a disc jockey to concentrate on the creative aspects of his or her performance and focus less on the function and operation of the performance equipment.
It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be within the scope of the present invention except as limited by the scope of the appended claims.
