     DETAILED DESCRIPTION 
     Display receiver devices may receive content from a number of different sources. These sources may utilize different technologies, and may even utilize different user input devices for accessing menus associated with the devices. For example, a display receiver device in the form of a television may be configured to interface with a DVD player, a media center computer, a movie-streaming service, and a digital video recorder, and yet each of these devices may have its own user interface, and oftentimes may be accessed by its own remote controller. Moreover, each time a user desires to watch content from a different source, the user may have to indicate on the television which source input to utilize (e.g., SOURCE  1 , SOURCE  2 , SOURCE  3 , etc.). Not only can this be cumbersome for the user, but typically the inputs do not indicate which input is associated with which device, so a user typically cycles through the source inputs until the desired source is selected. Furthermore, it may be challenging for a user to have a rich user experience with such a system since the content sourced to the display lacks any sort of interconnectivity. 
     Content signaturing allows a display receiver device to identify different content from a variety of sources. Signaturing allows the display receiver device to identify the content regardless of the source the content comes from and without that source having to be specially configured to report content information to the display receiver device. A display receiver device that is configured to signature content in this way may provide a unified user interface through which a user may interact to select content from various sources and/or to discover other relevant content. In this way, content from various disparate sources may be accessed through a single user interface presented on a display. Further, since the content is identified by the display receiver device, the unified user interface may display information about each content item in addition to providing an access point to the content item. Further yet, content from different sources may be associated with the identified content. Such a display receiver device may be further configured to provide a unified approach for interacting with the various sources based on inferences about which content source is controlled by which remote control, and/or provide consumption reports detailing content consumption behavior on that display device. 
     In some embodiments, a display receiver device may take the form of a display that includes a display screen for visually presenting the content. In other embodiments, a display receiver device may take the form of a set top box and/or peripheral receiver that is connected to a display screen that visually presents the content. The following description equally applies to both embodiments. The term “display” is used below to refer to both a stand-alone display device including an integrated display screen and a peripheral unit connected to a display screen. 
     Turning now to  FIG. 1 ,  FIG. 1  illustrates a display device  20  configured to display content on a display  22   a . As an example, display device  20  may be a television. It should be appreciated, however, that display device  20  with display  22   a  is just one example of a suitable display device. Thus, other suitable display devices include, but are not limited to, a computer monitor including a display  22   b , a laptop including a display  22   c , a mobile computing device including a display  22   d , a peripheral device configured to be connected to a display, etc. While the following discussion primarily focuses on display device  20 , it is to be understood that the content signaturing and related functionality may be implemented on a wide range of different content delivery devices. 
     Display device  20  may be configured to receive content for visual presentation on display  22   a  from a variety of sources. Some content sources may be peripheral content sources, such as external devices attached to display device  20 . Examples include, but are not limited to, a DVD player, a Blu-ray player, a set top box, a media center computer, a digital video recorder, a gaming console, etc. Other content sources may be integrated content sources which are directly integrated into display device  20 , such as a built-in television tuner. Some content sources, whether peripheral or integrated, may be network content sources configured to receive content via a network  30 , such as a movie-streaming service, Internet television, etc. 
     Content may be received via one or more source inputs  24  of display device  20 , wherein each source input is configured to receive a content signal from a corresponding content source. As an example, Input A may receive a content signal from a DVD player, Input B may receive a content signal from a gaming console, Tuner C may receive a content signal from a television tuner, etc. 
     In addition to displaying content received from various content sources, display device  20  may be configured to monitor the content signal at each input. For example, display device  20  may be configured to sample each content signal, so as to obtain sample information from each received content signal. Such sample information may then be utilized to identify the content from each of the sources, as described hereafter, so as to provide a richer user experience. 
     As illustrated in  FIG. 1 , display device  20  may further include a content identification module  26  for assisting in the identification of content from various content sources. Thus, although the content sources may not be related to one another, content identification module  26  allows the content from each of the sources to not only be identified, but also associated with one another and/or content from other sources, as described in more detail as follows. 
     Content identification module  26  may be configured to send sample information derived from each received content signal to a network-accessible remote service, such as a signature processor  28  accessible via a network  30  (e.g., the Internet). Display device  20  may derive such sample information in any suitable manner. For example, since display device  20  is configured to monitor the video and audio signals input to display device  20  from various sources, sample information derived from these signals may then be made available for content signaturing. As such, in some embodiments, display device  20  may further include a local signature acquisition module  32  to sample the content signal received by each source input and to prepare the sample information for content identification module  26 . The sample information may be derived from audio aspects of the content signal, video aspects of the content signal, ancillary data aspects (e.g., closed captioning, metadata, etc.) associated with the content signal, or other aspects of the received content signal. 
     In some embodiments, the sample information may include a digital signature derived from the received content signal. Thus, signature acquisition module  32  may be configured to perform such content signaturing. Such signaturing may include performing segmentation of the content, analyzing each segment, and/or providing metrics along various parameters. 
     In some embodiments, signaturing may include sending received content to signature processor  28  for remote processing. In such embodiments, the sample information sent to the signature processor may be a short segment of raw and/or compressed content. 
     In some embodiments, a digital signature may be derived from a video aspect of the received content signal. This may include dynamic chroma and luminance changes and/or object recognition such as face recognition, character recognition, etc. The digital signature may additionally or alternatively be derived from an audio aspect of the received content signal, such as an audio signature, a sequence of musical notes, a vector representation of audio dynamics and/or intensity, speech-to-text analysis, etc. Further yet, in some embodiments the digital signature may additionally or alternatively be derived from an ancillary data aspect of the received content signal, such as a digital encoding format and/or subformat(s), and/or embedded metadata such as closed caption information, DVB subtitles, etc. 
     Further, in some embodiments such signaturing may include multivariate signaturing, allowing content to be identified based on sampling wherein full information may not be available. In such a case, segmentation may be performed based on data aspects in the current streams. However, additional data may be utilized, such as that from extrinsic data sources (e.g., a separate metadata stream) to increase the accuracy of the signaturing. As a nonlimiting example, in some embodiments the multivariate signature may be encoded as a matrix of vectors. 
     Continuing with  FIG. 1 , signature acquisition module  32  of display device  20  may be configured to sample content signals in any suitable manner. For example, in some embodiments, signature acquisition module  32  may be configured to sequentially sample content signals received by different source inputs. As an example, signature acquisition module  32  may be configured to sequentially sample source inputs  24  of display device  20  once per minute. In some embodiments, signature acquisition module  32  may alternately sample the various source inputs, creating a relevant video and audio snapshot from each source input at a particular interval. Such an approach may be suitable for a display device that may not be capable of simultaneously decoding all possible input channels. However, more advanced display devices may have the resources and capability for signature acquisition module  32  to concurrently sample content signals received by two or more source inputs. Further, in some embodiments, signature acquisition module  32  may be configured to presample content signals received by different source inputs when the display is turned off. 
     Sample information, whether raw, compressed, or pre-processed, may then be sent to signature processor  28  via network  30 . Signature processor  28  may be configured to receive the sample information in any suitable manner. As an example, signature processor  28  may include service(s) corresponding to module(s) of display device  20 . For example, signature processor  28  may include a content identification service  34  configured to receive sample information from content identification module  26 . 
     Signature processor  28  may be configured to perform matching of a digital signature to a digital content fingerprint in a database of digital content fingerprints, for example, using content identification service  34 . For example, in the case of a multivariate signature encoded as a matrix of vectors, content identification service  34  may be configured to analyze the matrix of vectors, and find the most likely match for this matrix among a large database of related content that has been previously analyzed. 
     Further, such processing may include utilizing information derived from content signaturing for performing queries (e.g., via content identification module  26  and/or content identification service  34 ), such as a query on an Internet search engine. Such queries may provide a useful data stream that is not a broadcast data stream. Further, information from audio and video aspects of the signaturing may be combined with information from ancillary data aspects of the signaturing for additional analysis. Such analysis may confirm that the content item has been identified correctly, for example. 
     In some cases, such processing may include analyzing sample information to generate additional markup. For example, closed captioning data of a particular content item may be analyzed to determine additional markup for amending the metadata of that content item. 
     Upon obtaining and processing the sample information, signature processor  28  may be configured to send (e.g., via content identification service  34 ) content information back to content identification module  26 . Accordingly, content identification module  26  is configured to receive such content information for each corresponding content source from signature processor  28 . 
     The content information for the corresponding content source may indicate a content item embodied by the content signal received from that corresponding content source and from which the sample information is derived. Examples of content items may include, but are not limited to, a television show, a movie, a game, an internet video, etc. The content information may include any suitable information related to the content item, such as a program title, program rating, user rating, list of actors, summary, year made, etc. In this way, by performing the sample-based signaturing of inputs at the device level, and transmitting the signature information to an analysis service for remote processing, all content being sourced to display device  20  may be identified regardless of the source. 
     Continuing with  FIG. 1 , display device  20  may be further configured to provide a user interface based on the content information received from signature processor  28 . As an example, display device  20  may include a user interface module  36  to produce a unified user interface including a menu option for each content source. In addition to providing an access point to the associated content, each menu option may further include content information identified via content identification module  26  for the corresponding content source, described as follows. 
     For example, each menu option may include an image captured from the content signal received from the corresponding content source, such as a screenshot from the content item. As another example, each menu option may include an image included as part of the content information received from the signature processor for the corresponding content source, such as a movie poster, promotional game image, etc. As yet another example, each menu option may include a title included as part of the content information received from the signature processor for the corresponding content source, and/or any other such textual or other information included in the content information. 
     Such a unified user interface may be visually presented on display  22   a , such as illustrated at  38 . For example, each menu option  40   a - 40   f  may include a screen shot of what is available from that source (e.g., as sampled) and the title (e.g., as determined by content identification module  26  and signature processor  28 ). In some embodiments, these menu options may be displayed alongside a content item currently being displayed for primary viewing, such as content item  42 . In some embodiments the menu options (e.g., menu options  40   a - 40   f ) will include static images while the currently active content item (e.g., content item  42 ) includes moving images and active sound. 
     Display device  20  may include a switching module  44  which is configured to cause display  22   a  to visually present content delivered by the corresponding content source responsive to selection of a corresponding menu option of the unified user interface. It should be appreciated that visually presenting such content may be done in any suitable manner. For example, in some embodiments, the selected content may be brought into focus for primary viewing, for example, by replacing the content currently being displayed for the user (e.g., content item  42 ) with the selected content. In other words, the content item associated with the selected menu option is shown with moving images and active sound. In such a case, the menu options associated with the unified user interface may remain displayed. However, in some embodiments, the selected content may be brought into view, and all other content (e.g., content item  42 , menu options  40   a - 40   f , etc.) may be removed from view, so as to effectively “change the channel.” In this way, a user may switch between various video and audio input devices using images, text, audio, and/or other content-specific information as selectable menu items. 
     Content signaturing further provides for content from the various sources to be associated with one another. Thus, display device  20  may further include an association module  46  to associate the content item corresponding to the particular content source with one or more associated content items not corresponding to the particular content source. Such association can be done in any suitable manner. For example, display device  20  may utilize a local or remote database to manage digital signature information. In this way, association module  46  may itself look for correlations between different entries and/or other information (e.g., metadata from a program guide, a search engine, etc.). 
     As another example, in some embodiments, association module  46  may be configured to cooperate with a remote service to associate content, such as a remote association service  48  of signature processor  28 . In such a case, association module  46  may cooperate with a association service  48  to associate the content item corresponding to the particular content source with one or more associated content items not corresponding to the particular content source. In this way, signature processor  28  provides an analysis engine to determine associations that are then sent back to display device  20 , such that association module  46  may then associate the content. 
     Association module  46  may be configured to provide a content recommendation including the one or more associated content items. Such a content recommendation may indicate specific content items available to display device  20  (e.g., via source inputs  24 ) that are related to another of the content items available to display device  20 . For example, a content recommendation may indicate that the same content received via a first input is available, or will be available, to display device  20  in a different format via a second input. As another example, a content recommendation may indicate that a continuation of the content (e.g., a subsequent episode, a next disc of a television series, etc.) received via an input is available, or will be available, to display device  20  via another input. As yet another example, a content recommendation may indicate that related content (e.g., content with the same actor(s), director, subject matter, rating, etc.) is available, or will be available, via another input. 
     Further, association module  46  may be configured to record the one or more associated content items. For example, if the content recommendation indicates that the next episode is available via television programming, association module  46  may signal a digital video recorder to record the episode when the episode is broadcast. 
     Association module  46  may be further configured to provide permission for the one or more associated content items to be accessed via another device. Thus, if display device  20  is currently playing a movie, for example, association module  46  may allow the user to watch the movie on another display, such as display  22   c  of the user&#39;s laptop. A central permissions server may be utilized to facilitate such permissions. 
     Thus, whereas traditionally display devices present a user with fragmented content, content signaturing as described herein allows a display device to identify and associate the content being sourced to its various inputs. 
       FIG. 2  illustrates an example layout for a unified user interface  50 , wherein a current view  52  is utilized to display content currently being displayed for the user. At  54 , an image corresponding to the user&#39;s profile may be displayed. At  56 , menu options for content from connected devices may be displayed. At  58 , menu options for content from virtual services may be displayed, such as associated video clips available via the Internet. In this way, content from different content sources, whether physical inputs to the display device or virtual inputs over a network (e.g., the Internet), are displayed for the user. Each of the menu options provides a visual indication of the actual content that is available from the source corresponding to that particular menu option. As described above, a particular menu option may be selected (e.g., using a remote control, a game controller, vision input, voice input, or another input mechanism) in order to cause the display device to present the content corresponding to that menu option. 
     Moreover, whereas traditional home entertainment systems typically suffer from decentralized control, display device  20  may be further configured to provide centralized control, allowing a user to interact with the variously-sourced content in a centralized manner by relating individual remote control mechanisms to one another, so as to infer functionality of the input device. As such, display device  20  may further include one or more remote control inputs  80 , wherein each remote control input is configured to receive a remote command signal from one or more remote controls, each remote control corresponding to a particular content source. The individual remote control inputs may include infrared inputs, radio frequency inputs, wireless network inputs, etc. 
     Display device  20  may further include a remote inference module  82  to infer which content source is controlled by a remote control  84  based on an activation of a corresponding source input. In some embodiments, such inferring may occur during a natural learning phase. For example, remote inference module  82  may determine that each time a user presses a button on remote control  84  associated with a particular command, they also press other buttons on other remote controls associated with other functionalities. As such, remote inference module  82  may “learn” that a selection of the button on remote control  84  corresponds to signaling commands for all of these functionalities. 
     Remote inference module  82  may be configured to provide centralized control in any suitable manner. For example, in some embodiments, remote inference module  82  may allow display device  20  to essentially take over the behavior itself. In such a case, upon learning the behavior that is to be implemented in response to a selection on remote control  84 , display device  20  may signal such behavior. 
     However, in some embodiments, remote inference module  82  may allow additional functionality to be provided to remote control  84 . For example, upon inferring functionality to be associated with a particular button, remote inference module  82  may send a functionality update directly to remote control  84  to update the programming of remote control  84 . However, in other embodiments, remote inference module  82  may send updated programming based on learned inferences to remote control  84  over a network, such as network  30 . 
     In this way, whereas traditionally the burden is on the user to program a remote control, display device  20  can essentially “watch” all remotes and observe the effect each signal received from a particular remote has on the content on the display. As such, the display device may infer how the audio/video system is set up, and how the remotes are set up. 
     Moreover, display device  20  may be further configured to automatically switch (e.g., via switching module  44 ) to a source input corresponding to the content source that the remote inference module has inferred is controlled by the remote control. 
     Display device  20  may be further configured to provide information regarding the consumption at each input. 
     Accordingly, display device  20  may further include a reporting module  86  to provide a consumption report detailing content consumption via each source input. In some embodiments, reporting module  86  may be configured, for example, to use content information received via content identification module  26  to provide the consumption report. The consumption report may include any suitable information, such as information regarding the content that is played (e.g., title, channel, etc.), the source from which the content originated, the times and durations at which the content is played, at which points during playback is content playback stopped, what content is switched to when content playback is stopped (i.e., what subsequent content item, as identified via the content identification module, interrupts viewing of a preceding content item), ambient noise levels in a viewing environment (e.g., as measured by a microphone) at different points in content playback, user profile information, or virtually any other type of reportable information. In this way, the consumption data may provide a full history of a user&#39;s viewing behavior. 
     Further, reporting module  86  may be configured to send the consumption report to a reporting service  88  via network  30 . In other embodiments, reporting module  86  may be configured to transmit the consumption report to an aggregation service over low-bandwidth connections. 
     Reporting service  88  of signature processor  28  may be configured to analyze consumption report(s). Such analysis may be utilized, for example, to provide targeted, relevant content suggestions to the user. Analysis of consumption reports may include content analysis, user interface analysis, device analysis, user viewing behavior analysis, etc. Moreover, such analysis may include aggregation of consumption reports across several users to determine trends among user populations, which may be valuable to content providers, advertisers, and/or other parties interested in the content consumption trends of a particular population and/or targeted demographic. 
     Turning now to  FIG. 3 ,  FIG. 3  illustrates an example method  100  of providing content signaturing. At  102 , method  100  includes receiving a content signal from one or more content sources. Each signal may be received, for example, via a source input. At  104 , method  100  includes sending sample information derived from each received content signal to a signature processor. In some embodiments, method  100  may optionally include deriving the sample information from each received content signal, as indicated at  106 . Further, in some embodiments, deriving a digital signature from the received content signal, as indicated at  108 . 
     At  110 , method  100  includes receiving from the signature processor content information for each corresponding content source. At  112 , method  100  optionally includes producing a unified user interface including a menu option for each content source. Each menu option may include, for example, content information identified for the corresponding content source. 
     In some embodiments, method  100  may optionally include receiving a selection of a menu option of the unified user interface, as indicated at  114 . Accordingly, at  116 , method  100  may optionally include visually presenting content delivered by the corresponding content source responsive to such a selection. 
     Further, in some embodiments, method  100  may optionally include associating one or more content items corresponding to a particular content source with one or more associated content items not corresponding to the particular content source, as indicated at  118 . In some embodiments, such association may include providing a content recommendation including the one or more associated content items, as indicated at  120 . 
     Further yet, in some embodiments, method  100  may optionally include providing a consumption report detailing content consumption via each source input as indicated at  122 . In such a case, method  100  may further include sending the consumption report to a reporting service, as indicated at  124 . 
     Further yet, in some embodiments, method  100  may optionally include inferring which content source is controlled by which of one or more a remote controls, as indicated at  126 . As an example, such inferring may be performed during a natural learning phase. 
     In some embodiments, the above described methods and processes may be tied to a computing system including one or more computers. In particular, the methods and processes described herein may be implemented as a computer application, computer service, computer API, computer library, and/or other computer program product. 
       FIG. 1  schematically shows a nonlimiting computing system in the form of display device  20  that may perform one or more of the above described methods and processes. Display device  20  is shown in simplified form. It is to be understood that virtually any computer architecture may be used without departing from the scope of this disclosure. In different embodiments, display device  20  may take the form of a television, desktop computer, laptop computer, tablet computer, home entertainment computer, network computing device, mobile computing device, mobile communication device, gaming device, mainframe computer, server computer, etc. 
     Display device  20  includes a logic subsystem  130  and a data-holding subsystem  132 . Display device  20  may include a display  22   a,  communication subsystem  134 , and/or other components not shown in  FIG. 1 . Display device  20  may also optionally include user input devices such as remote controllers, keyboards, mice, game controllers, cameras, microphones, and/or touch screens, for example. 
     Logic subsystem  130  may include one or more physical devices configured to execute one or more instructions. For example, the logic subsystem may be configured to execute one or more instructions that are part of one or more applications, services, programs, routines, libraries, objects, components, data structures, or other logical constructs. Such instructions may be implemented to perform a task, implement a data type, transform the state of one or more devices, or otherwise arrive at a desired result. 
     The logic subsystem may include one or more processors that are configured to execute software instructions. Additionally or alternatively, the logic subsystem may include one or more hardware or firmware logic machines configured to execute hardware or firmware instructions. Processors of the logic subsystem may be single core or multicore, and the programs executed thereon may be configured for parallel or distributed processing. The logic subsystem may optionally include individual components that are distributed throughout two or more devices, which may be remotely located and/or configured for coordinated processing. One or more aspects of the logic subsystem may be virtualized and executed by remotely accessible networked computing devices configured in a cloud computing configuration. 
     Data-holding subsystem  132  may include one or more physical, non-transitory, devices configured to hold data and/or instructions executable by the logic subsystem to implement the herein described methods and processes. When such methods and processes are implemented, the state of data-holding subsystem  132  may be transformed (e.g., to hold different data). 
     Data-holding subsystem  132  may include removable media and/or built-in devices. Data-holding subsystem  132  may include optical memory devices (e.g., CD, DVD, HD-DVD, Blu-ray Disc, etc.), semiconductor memory devices (e.g., RAM, EPROM, EEPROM, etc.) and/or magnetic memory devices (e.g., hard disk drive, floppy disk drive, tape drive, MRAM, etc.), among others. Data-holding subsystem  132  may include devices with one or more of the following characteristics: volatile, nonvolatile, dynamic, static, read/write, read-only, random access, sequential access, location addressable, file addressable, and content addressable. In some embodiments, logic subsystem  130  and data-holding subsystem  132  may be integrated into one or more common devices, such as an application specific integrated circuit or a system on a chip. 
       FIG. 1  also shows an aspect of the data-holding subsystem in the form of removable computer-readable storage media  136 , which may be used to store and/or transfer data and/or instructions executable to implement the herein described methods and processes. Removable computer-readable storage media  136  may take the form of CDs, DVDs, HD-DVDs, Blu-ray Discs, EEPROMs, and/or floppy disks, among others. 
     The terms “module,” “program,” and “engine” may be used to describe an aspect of display device  20  that is implemented to perform one or more particular functions. In some cases, such a module, program, or engine may be instantiated via logic subsystem  130  executing instructions held by data-holding subsystem  132 . It is to be understood that different modules, programs, and/or engines may be instantiated from the same application, service, code block, object, library, routine, API, function, etc. Likewise, the same module, program, and/or engine may be instantiated by different applications, services, code blocks, objects, routines, APIs, functions, etc. The terms “module,” “program,” and “engine” are meant to encompass individual or groups of executable files, data files, libraries, drivers, scripts, database records, etc. 
     It is to be appreciated that a “service”, as used herein, may be an application program executable across multiple user sessions and available to one or more system components, programs, and/or other services. In some implementations, a service may run on a server responsive to a request from a client. 
     Display  22   a  may be used to present a visual representation of data held by data-holding subsystem  132 . As the herein described methods and processes change the data held by the data-holding subsystem, and thus transform the state of the data-holding subsystem, the state of display  22   a  may likewise be transformed to visually represent changes in the underlying data. Display  22   a  may include one or more display devices utilizing virtually any type of technology. Such display devices may be combined with logic subsystem  130  and/or data-holding subsystem  132  in a shared enclosure, or such display devices may be peripheral display devices. 
     When included, communication subsystem  134  may be configured to communicatively couple display device  20  with one or more other computing devices. Communication subsystem  134  may include wired and/or wireless communication devices compatible with one or more different communication protocols. As nonlimiting examples, the communication subsystem may be configured for communication via a wireless telephone network, a wireless local area network, a wired local area network, a wireless wide area network, a wired wide area network, etc. In some embodiments, the communication subsystem may allow display device  20  to send and/or receive messages to and/or from other devices via a network such as the Internet. 
     It is to be understood that the configurations and/or approaches described herein are exemplary in nature, and that these specific embodiments or examples are not to be considered in a limiting sense, because numerous variations are possible. The specific routines or methods described herein may represent one or more of any number of processing strategies. As such, various acts illustrated may be performed in the sequence illustrated, in other sequences, in parallel, or in some cases omitted. Likewise, the order of the above-described processes may be changed. 
     The subject matter of the present disclosure includes all novel and nonobvious combinations and subcombinations of the various processes, systems and configurations, and other features, functions, acts, and/or properties disclosed herein, as well as any and all equivalents thereof.
