The current invention relates to entertainment devices and, more specifically, to systems and methods for automatic control over peripheral equipment connected to media management systems.
Media management systems are becoming increasingly popular among consumers of entertainment media who need assistance in managing their ever-growing collections of CD's, DVD's, MP3 files and media-playing equipment. Media management systems interface with a variety of sources of media. For example, a media management system may receive media from different CD-changers, different DVD-changers, the Internet, a CD player, a DVD player, a personal computer and a hard disk drive. Media management systems also interface with a variety of media players. For example, the same media management system may play media on a monitor, a television, and on different audio receivers. Media management systems are also typically able to display information about the media available on the connected sources of media on a user interface. The user interface allows the user to communicate instructions to play selected pieces of media.
Developers of media management systems aim to interface with as wide a variety of media sources as possible. Different media sources make media available in forms that provide different capabilities for enhancing the user experience. Web-sites on the Internet offer users the convenience of downloading music or other audio as MP3 files. Video works and music are now available on different types of discs such as DVD, CD, Super-Audio CD (SACD), WAV, MP3, DVD-Audio, etc. offering the user options such as choices in surround modes available to the user. In this regard, audio/video receivers now have a variety of inputs to allow a user to connect alternative media sources. A user may connect media sources, audio receivers and video players to a media management system to take advantage of the many options available to experience the media.
Providing such variety of capabilities imposes on the user the burden of learning and understanding the capabilities available on the user's media management system. Moreover, the user typically manually configures the manner in which a selected piece of media will be played each time it is played. For example, a user may direct an SACD disc to a 6-channel analog input on the receiver when playing an SACD disc. Then, if the user wishes to listen to an MP3 file, the user may manually configure the media management system to direct the output to a 2-channel input on the receiver. Such manual configuration for each type of media source becomes burdensome to the user.
Based on the foregoing, a need exists for automatically configuring receivers to play media using sound and video modes according to characteristics of the media.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with features and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail, so as not to obscure the present invention.
1. Overview
The control signal connection 51, the digital connection 52, the 2-channel analog connection 54, the 6-channel analog connection 56, and the video connection 58 are communicatively coupled to a media receiver 38. The media receiver 38 may be configured in various arrangements. For example, the media receiver 38 may comprise a pre-amplifier. As another example, the media receiver 38 may include a pre-amplifier and a decoder that decodes media for playing the media in one of a variety of play modes. As yet another example, the media receiver 38 may comprise a pre-amplifier and an amplifier. As still yet another example, the media receiver 38 may include a pre-amplifier, an amplifier, and a radio frequency tuner. Other examples of media receiver arrangements are also possible.
The main processor 15 could comprise one or more processors, such as a general purpose processor and/or a digital signal processor. The main processor 15 executes program instructions in order to work cooperatively with the plurality of media source I/O ports 12, the control port system 14, the user interface 16, the mode configuration process 17, and the media player interface 18.
The plurality of media source I/O ports 12 are coupled to a plurality of media source devices or systems. By way of example, the plurality of devices or systems may include the Internet 20, a personal computer 24, a first disc changer 26a, a second disc changer 26b, and a third disc changer 26c. Other examples of the devices or systems coupled to the plurality of media source I/O ports 12 are also possible.
The Internet 20 is preferably connected to a network hub 22, which provides Internet access to the personal computer 24 in a local area network environment. The personal computer 24 may connect to the media management system 10 using any suitable data connection (e.g. RS232, Ethernet, wireless Ethernet, etc.). In a preferred embodiment, the personal computer 24 connects to the media management system 10 at an Ethernet connection over which the media management system 10 connects to the Internet 20.
The first, second and third disc changers 26a-c may be any disc changer operable to hold a plurality of media discs such as audio CDs (compact discs), Super Audio CD's (SACD), and DVD's (digital versatile disc or digital video disc). The disc changers 26a-c connect to the media management system 10 at the media source I/O ports 12 to communicate media to the media management system 10.
The media management system 10 may include a control port system 14 for controlling the disc changers 26a-c. The control port system 14 may provide control signals to disc changers 26a-c via infrared (IR) (e.g. wired IR or wireless IR), or serial connections (e.g. two-way serial or S-Link based connections). Other examples of control signal types provided by the control port system 14 to the disc changers 26a-c are also possible.
The control port system 14 may interface (e.g. via an RS-232 serial cable) with a home remote control system 28. As an example, the home remote control system 28 may provide control for the media management system 10, as well as control for other systems, such as appliances and/or a furnace in a home.
The media management system 10 accesses each of the plurality of media sources and organizes information about the media that is accessible to the user of the media management system 10 in the media database 19. The media database 19 may be any type of storage system. For example, the media database 19 may comprise a disc-based mass storage device, a flash memory system, or a combination of flash memory and disc-based memory. The media database 19 stores media unit records, i.e., records containing information about media units that may be received from the media sources. As used herein, the term media unit shall refer to any playable or renderable piece of media, such as a song, a movie, a picture, a track on a disc, a portion of audio/visual programming, or any other audio and/or video segment.
In exemplary embodiments, a media unit record contains information in the form of characteristics such as a title (e.g. a CD title, a DVD title, or a movie title), a song, a genre, a location, an artist, a date, and/or a media type. The location defines the location of the media unit on the media source. For example, a media unit record for a song may denote that the song is located in a particular slot on a particular tray in a particular one of the CD changers that may be connected as a media source to the media management system 10. As another example, a media unit record for a song may denote that the song is located as a particular track on a disc, such as a CD, DVD, and/or SACD. An artist defines a performer's work or group of performers' work recorded as a media unit. A date, for example, may define the day which a media unit was recorded or a day the media unit was released by a recording studio. Other examples of the date are also possible.
The media type defines the format used to encode a media unit. Various media types are available for encoding audio. For example, a media type may include the Motion Picture Experts Group—audio layer 3 (MP3) format, a CD format, a SACD format, a DVD format, a waveform audio (WAV) format, pulse code modulation (PCM) format, free lossless audio code (FLAC) format, or an advance audio coding (AAC) format. The media type may also define whether the media unit is encoded as (i) encrypted or unencrypted media, or (ii) compressed or uncompressed media. Other examples of formats for digitally encoding audio are also possible.
Further, a media type format may have a variety of encoding characteristics. For example, an audio recording may be encoded as an MP3 file in mono format having a data rate of 96K bits per second (bps), or as an MP3 file in stereo format having a data rate of 96K bps, or as an MP3 file in stereo format having a data rate of 192K bps. As another example, the AAC format could be encoded using a variable bit rate or a constant bit rate and with a different amount of audio channels, (e.g. 1 channel, 2 channels, etc.). Other examples of encoding characteristics of the MP3 format, the AAC format, or other media type are also possible.
The media management system 10 may display selected information about the media from the media unit records stored in the media database 19 on a display 32. The media management system 10 may also allow the user to configure and select media to play using a keyboard 34, an IR remote control 30 or another suitable input device. The media management system 10 may include a user interface 16 that processes user input and output via the display 32 and the keyboard 34 and provides configuration and execution processes to allow the user to manage and play the media obtained from the media sources. As an example, the display 32 may comprise a touch-screen that allows a user to (i) configure and select media, and (ii) select play modes, by touching the touch-screen while a configuration and selection screen is shown on the display 32.
In a preferred embodiment, the user interface 16 may be coupled to a configuration process 17 that allows the user to configure the media receiver 38 to play the media in accordance with requirements specified in a play mode. The configuration process 17 may display screens to query the user prompting the user to enter information about play modes for the particular media types available.
As an example, the user may specify that a song in an MP3 format will be played on a receiver via a 2-channel analog connection. In this regard, for 2-channel analog, the media management system 10 processes the MP3 song by extracting the left and right channel analog signals of the MP3 song and then sends the left and right analog signals 55 to a corresponding 2-channel analog connection at the media receiver 38. The media receiver 38 may process the left and right channel signals 55 by amplifying the signals before outputting the signals to a left speaker and a right speaker respectively.
As another example, the MP3 song may also be communicated digitally (in MP3 or other digital format) to another digital player. In this regard, the user may specify a receiver connection that sends a digital signal 53 from the digital connection 52 to a corresponding digital connection at the media receiver 38. As yet another example, the user may specify a receiver connection that sends 6-channel audio signals 57 from the 6-channel audio connection 56 to a corresponding 6-channel audio connection at the media receiver 38.
The 2-channel analog receiver connection is only one of many media receiver connections that may be specified for a given media type. Other examples of media receiver connections include: (i) 5.1 analog connections, and (ii) digital connections, such as a 2-channel digital connection, a 5-channel digital connection, or a 7-channel digital connections. Other examples of media receiver connections are also possible. These media receiver connections may correspond directly to the connections available on the media receiver 38.
Audio signals received at the media receiver 38 may be played through one or more speakers coupled to the media receiver. As an example, the media receiver 38 is shown connected to a first speaker 40 (e.g. a speaker for a left-audio channel), a second speaker 42 (e.g. a right-channel speaker), and a third speaker 44 (e.g. a speaker for a center-audio channel). Other examples of the amount of speakers coupled to the media receiver 38 and/or the audio signal played through a particular speaker are also possible.
The media receiver 38 may also drive video equipment, such as a television or monitor 36 via a video connection 58. In this regard, a video signal 59 is sent to the television or monitor 36. The video formats may include compressed media (video and/or audio content), uncompressed media, or a combination of compressed and uncompressed media. Examples of video formats include: (i) Motion Picture Experts Group (MPEG)-1, (ii) MPEG-2, (iii) MPEG-4, (iv) high definition television (HDTV), (v) National Television System Committee (NTSC), (vi) Phase Alternating Line (PAL), (vii) Joint Photographic Experts Group (JPEG), and (viii) Video-CD. Other examples of video formats are also possible.
The media receiver 38 may also use play modes specific for different video formats as well. For example, a Denon receiver may be commanded to configure the receiver according to special play modes that the receiver is designed to understand. The media management system 10 may send commands specifying play modes, such as (i) Digital Theater System (DTS) (e.g. DTS-ES, DTS-Neo:6, DTS-Digital Surround, or DTS-96/24), (ii) Dolby Pro Logic (DPL) (e.g. DPL II, DPL Movie, or DPL Music), (iii) Dolby Digital (e.g. Dolby Digital EX) (iv) THX (e.g THX Cinema), (v) Wide Screen, (vi) Super Stadium, (vii) Rock Arena, (viii) Jazz Club, (ix) Classic Concert, (x) Mono Movie, (xi) Matrix, (xii) 5-Channel Stereo, (xiii) 7-Channel Stereo, (xiv) Stereo, (xv) Pure Direct, or (xvi) Direct.
These play modes (and others that may be defined) may be used with media receivers (e.g. media receiver 38) that are able to interpret these play modes and configure characteristics about the receiver to play the media. Configurable characteristics include equalization (e.g. equalizer settings), level adjustments (e.g. input level, or speaker level), delay time, noise reduction, bass setting, and a balance setting. Other examples of configurable characteristics are also possible.
In a preferred embodiment, the media management system 10 couples a control signal 50 to the media receiver 38 to communicate configuration instructions for playing a particular media unit. The control signal 50 may communicate commands to configure the receiver 38. The commands may be specific to the type (brand or make) of receiver based on the receiver's command set. For example, the media receiver 38 may be a Denon or Marantz receiver that may be controlled by the control signal 50. Examples of Denon receivers that may be controlled by the control signal 50 include:
In exemplary embodiments, the media management system 10 configures the media receiver 38 to play media using a selected receiver connection. The selected receiver connection is used to configure the receiver 38 by ensuring that the media is communicated on the receiver connections that correspond to the media type (e.g. encoding format such as MP3, SACD, DVD-Audio, FLAC, AAC, etc.). In exemplary embodiments, the user is provided with the configuration process 17 to configure how media will be played automatically as a function of its media type and/or genre, artist, or any other suitable characteristic that may be included in the media unit record.
2. An Exemplary Configuration Process
In the configuration process 17 in
Those of ordinary skill in the art will appreciate that the receiver connection setting screen 80 and the play mode setting screen 82 are shown as examples of configuration screens that a user may use to select how the media receiver 38 will be automatically configured to play a selected media unit. The play mode setting screen 82 may use other characteristics, such as artist, title, or location, to select the play that will be used by the media receiver 38 when playing the selected media unit. Other examples of the receiver connection setting screen 80 and/or the play mode setting screen 82 are also possible.
3. An Exemplary System and Method for Playing Media
As shown in
The play selection function 110 may retrieve one or more records from the media data base 19. For example, the play selection function 110 retrieves a media unit record 190 from the media database 19 for a selected media unit. The media unit may be selected directly when the user selects the media unit from the user interface. The media unit may also be selected as part of a playlist that contains the name of the media unit and retrieves the information while processing the songs on the playlist. The playlist may be user defined or pre-defined in an album or other type of collection of media units.
The media unit record 190 contains information about the media unit that has been selected for play. As an example, the media unit record 190 may include information that identifies (i) a media unit as an audio (music) or a video media unit, (ii) an artist name, such as “Joe Smith” (iii) a title, such as “Joe Smith's First Album” (iv) a genre, (v) a date, such as a recording date, (vi) a label, such as Radio Corporation of America (RCA), (vii) a location, such as an internal hard drive in a personal computer, and (viii) a media type, such as MP3. Other examples of information in a media unit record 190 are also possible.
As another example, the play selection function 110 may also retrieve a media type configuration record 192, which may be configured as described above with reference to the media type configuration record 100 in
For instance, the receiver connection shown in the media type configuration record 192 for MP3 is 2-Channel Analog. As additional examples, if the media type is CD-audio or a WAV file, then the receiver connection is 2-channel digital, or if the media type is DVD-audio or SACD, then the receiver connection is the analog 5.1 connection. Other examples of receiver connections identified in the media type configuration record 192 are also possible.
As another example, the play selection function 110 may retrieve a play mode record 194. The play mode record 194 includes play modes that correspond to a genre characteristic of a media unit. As an example, a play mode “rock arena” corresponds to a rock genre, a play mode “classic concert” corresponds to a classical genre, and a play mode “jazz club” corresponds to a jazz genre. As another example, a user may select a play mode “rock arena” for a jazz genre. Other examples of play modes corresponding to a characteristic of a media unit are also possible.
The play selection function 110 determines a play mode selection based on the media unit record 190 and the play mode record 194. For instance, since the genre characteristic of the media unit record 190 is Jazz and the play mode for the Jazz genre is Jazz Club (as defined by the play mode record 194), the play selection function 110 determines the play mode selection as being Jazz Club.
The play selection function 110 interfaces to a media play processor 170 to communicate the play mode selection and the receiver connection selection for a selected media unit. The media play processor 170 receives the play mode selection, the receiver connection selection, as well as a media receiver type record 196. The media receiver type record 196 identifies the type of receiver coupled to a media management system. For example, the media receiver type record 196 may identify a receiver as being a Denon brand receiver having a model number of AVR-2803.
The media play processor 170 receives the media signals 120 of the selected media unit from the media source I/O ports 12 shown in
In one exemplary embodiment, the media play processor 170 communicates a control signal 60 to the control signal connection 51, for transmission in turn to the media receiver 38. The control signal 60 communicates a control instruction to the media receiver 38 that instructs the media receiver 38 to use a particular receiver connection and one of a plurality of play modes in accordance with the instruction. For example, the media play processor 170 may request that the media receiver 38 use a play mode called “Rock Arena.” The media receiver 38 would be capable of using various specific settings of characteristics such as tone, equalizer settings, noise reduction, delay time, bass setting, balance setting, and level adjustments to output sound in a manner that may be characterized as sounding like “Rock Arena.” The media receiver 38 would also be compatible with the control instruction it receives.
As another example, the media play processor 170 may request that the media receiver 38 switch an input source for media signals to a particular receiver connection. In this regard, the media play processor 170 requests the media receiver 38 to use receiver connections of the media receiver that are coupled to receiver connections at the media player interface 18. For example, the media play processor 170 may request the media receiver to use a 2-channel analog receiver connection that is coupled to the 2-channel analog connection 54. In this regard, the media play processor 170 will route the media signals 120 to the 2-channel analog connection 54 as 2-channel analog signals 62, for transmission in turn to the 2-channel analog receiver connection at the media receiver 38. Other signals that may be sent by the media play processor 170 are signals sent to the digital connection 52, the 6-channel analog connection 56, or the video connection 58. These signals are not shown for clarity of the example above.
Specific media receivers are already capable of such functionality. Tables 1-10 contain categories of control instructions and other information that may be communicated to the media receiver 38 on a control signal 50 to configure the media receiver 38. The control instructions in Tables 1-10 are for a Denon AVR-SR9200. Those of ordinary skill in the art will appreciate that Tables 1-10 shows just one example of the types of control instructions that may be defined for other media receivers.
