Title: Electronic information hierarchy

Description:
BACKGROUND 
     Recent years have witnessed the development of smart phones and wireless devices that carry data in addition to telephone conversations. Some devices, however, have screens that do not adapt themselves well to displaying certain content (e.g., complex Web pages and/or two dimensional grid guide listings). A user may be forced to constantly zoom in and out to access data, and may become lost or confused due to the small screen area, and data organization, of the portable device 
     Therefore, there is an increasing need for simpler and more appealing ways to search for and access content on display devices. 
     BRIEF SUMMARY 
     Aspects of the disclosure relate to systems and methods for providing and/or displaying data in a hierarchy. The hierarchy of data may be configured to display content, available from, for example, various content items. In one embodiment, a system may be configured to display and permit navigation of multidimensional (e.g., time and content item) data on a display device. The display devices may be variously configured to include large and small devices, mobile and fixed devices, and other suitable displays. In certain embodiments, a display device may be in operative communication with a more stationary object. As one example, many home appliances (such as refrigerators) are increasingly being manufactured with one or more display devices. Thus, aspects of the current disclosure may be implemented on any display device and are not restricted to display devices of portable devices. 
     In another embodiment, a display device may be configured to display a first layer of an expandable hierarchy of data as a single column along a first axis. The axis may be either in a vertical and/or horizontal orientation. The single column may display, for example, a list of media items such as items. For example, channel listings from one or more service providers may be displayed. In some embodiments, the single column may provide a listing of data items from a plurality of different items. 
     In yet further embodiments, selection of a media item may result in a second layer of the expandable hierarchy of data to be displayed. The second layer may include media offerings associated with the selected media item. The media offerings may be displayed along the first axis (e.g., vertical axis) (in one or more rows) within the column. In certain embodiments, at least two channel listings of the first layer remain displayed along the vertical axis. The quantity of media offerings displayed in response to receiving the user input may be determined or selected by one or more methodologies and may be dependent upon user preferences, screen size, and/or device type. Further, the quantity to be displayed may be specific to a particular type of information being displayed (e.g., group of listings). In one embodiment, the first and the second layer form an accessible item such as a unitary accessible item. Alternatively, the second layer may scroll within an expanded portion of the scroll listing in the first layer. 
     In accordance with other embodiments, a user input selecting one of the displayed offerings of the second layer may cause the expansion of at least a portion of the second layer. In one embodiment, a third layer may be introduced within the axis (e.g., a vertical axis). In one embodiment, at least a portion of the first, second and third layers may form a single unitary accessible item. In one embodiment, the third layer may include descriptive content of the selected item (e.g., a media item) along the same axis (e.g., vertical axis). The quantity of offerings (e.g., media offerings) displayed in response to receiving the user input may be determined or selected by one or more methodologies. In yet further embodiments, a user input may identify at least a portion of the descriptive content to be displayed in response to the selection of first layer information (e.g., media offerings). Identification of selection of the descriptive content may be specific to first layer information (e.g., media offering or group of media offerings). In still yet further embodiments, a selectable action for initiating playback of the selected media may be made in addition to displaying descriptive content of the selected media offering. Selectable actions may include, but are not limited to, play, rewind, fast forward, and/or stop. 
     In another embodiment, the single column of the first layer comprises a substantially uniform horizontal width between two vertical boundaries that are parallel with the first vertical axis. In further embodiments, the portion of the first layer content offerings associated with the selected data listing displayed on the second layer in response to the first user input form a column having the same horizontal width as the single column of the first column. In one embodiment, the media content is displayed within the horizontal boundaries formed by the expandable hierarchy. 
     In one implementation, displaying playback of the selected content (e.g., media offering) may be provided on a display region within the two vertical boundaries of the single column of the first layer. In another embodiment, the portion of media offerings displayed on the second layer in response to a selection of a media item collectively form a top boundary and a bottom boundary separated by a vertical distance that is substantially identical to the media item that was selected by the first user input. In yet other embodiments, playback of the selected media offering may occur on the device but outside (either partially or fully) the boundaries of the single column of the first layer. In still yet another embodiment, playback of the selected media offering may occur on one or more separate devices, e.g., devices such as one or more televisions or other displays. 
     Other aspects of the disclosure relate to a plurality of layers configured to provide a selectable collection of data (e.g., images, text, etc.) that permits navigation without losing context and/or orientation. In this regard, implementation of certain embodiments may further reduce the quantity of user inputs required to navigate the data. For example, in exemplary embodiments, a user may navigate multiple layers of hierarchical data without losing context as to his/her location in the hierarchy with a single digit (e.g., a thumb). The user can easily move along the first layer, drop to subsequent layers, move along subsequent layers and back out again while at all times not becoming lost in the data. Further, in embodiments that move along a single axis, the user has intuitive access to the data by continuing to scroll by simply swiping the layered data. In one implementation, data may be rendered based upon the capabilities (and/or settings of) the computing device accessing the data. 
     An accessed collection of data may include multiple forms of data (e.g., textual, image, and/or video). As one example, modern websites are often configured to simultaneously provide multiple media types. Depending on the capabilities, configuration, and/or user settings of a computing device, a website (or portion thereof) may be rendered to be displayable as a single column comprising a plurality of data entries along a first vertical axis. For example, when rendering a website designed for a computer monitor on a phone, rendering the data in an alternate format may be desirable. For example, rather than have related data appear across the entire screen in two dimensions, the data can appear as multiple dimensions arranged along an axis. 
     In an exemplary embodiment, a two dimensional program guide with video of the selected program in the upper right corner, information about the selected program in the upper left corner, and a two dimensional information grid with time on one axis and channels on a second axis may be rendered along a single axis in accordance with aspects of this invention. For example, the channels may appear in the top layer information and be scrolled through along one axis (e.g., vertical). Selecting a channel may split the displayed channels separating them along the axis and placing second level information (e.g., time and associated program) between them. Selecting a time/associated program may then split the information again along the same axis (e.g., either vertical or horizontal) and bring up third level information in the opened area (e.g., information about the show). Selecting the third level information may bring up fourth level information such as play, record, send, fast forward, rewind between the second level information. The fourth level information may also be displayed full screen. 
     The items of data displayed along the axis may represent a different type of data from one or more items (such as websites). In still yet another embodiment, one or more filters may be utilized to determine whether an asset should be rendered. Rendering of assets (for example, from a website) may consider associations or commonalities among the assets. For example, different assets may relate to first group (e.g. a first article or media offering among a plurality articles or media offerings). The rendered assets may be arranged within a hierarchy of data having multiple layers. 
     The expansion of a first layer to display a second layer may be responsive to the receipt of a user input configured to select one of the displayed data items. In one embodiment, the second layer may comprise information regarding media content. For example, in one embodiment, information regarding a video asset may be displayed. The information may include, for example, a caption, description, length, still image, quality information or combinations thereof. In yet another embodiment, a reduced bit rate version of the video asset may be provided. In still yet another embodiment, the video, in its original bit rate, may be displayable. The second layer, as well as one or more subsequent layers, may be displayed along the same first vertical axis as the first layer. For example, the bit rate displayed may be variable based on the device running the application and/or the connection to the device. Where the device is connected via WiFi, a first image quality may display. As the user walks out of the house and switches to 4G, a second image quality may be played. As the user enters his home and transfers a football game to his television, a third image quality may be displayed. 
     The preceding presents a simplified summary of some aspects in order to provide a basic understanding of some features described in this disclosure. The summary is not an extensive overview of the disclosure. It is neither intended to identify key or critical elements of the disclosure nor to delineate the scope of the disclosure. The summary merely presents some concepts of the disclosure in a simplified form as a prelude to the description below. 
     In accordance with another embodiment related to, for example, content listings, a first user input selecting one of the displayed items along an axis (e.g., channels and/or media content) may result in expanding the first layer. The first layer is multidimensional in that a second, third, fourth, etc., layer of information exists associated with the first layer. Selection of an item in the first layer allows the first layer to be expanded along the axis and have second layer information inserted between the first layer information. The second layer information may appear as a three dimensional scroll wheel, in a box, and/or as a separate window. The second layer information may then be scrolled through without impacting the location in the first layer information. In one exemplary embodiment, pressing a button such as a “home” button, back button, and/or escape button may take a user from a deeper layer up through the hierarchy to a higher layer. Clicking an item, in certain embodiments, may take a user to a sequentially lower layer in the hierarchy. In this manner, for example, the user may have media items listed in the first layer, e.g., NBC, Youtube, Fox, Yahoo, Pandora. In this example, the user may scroll along one axis to select different elements in the first layer (e.g., media items). Once the user has selected an item in the first layer (e.g., NBC), a second layer opens. In embodiments, the second layer may open along a single axis, splitting apart first layer information and inserting second layer information. This allows the user to move vertically up and down layers of information along the same axis by moving aside the first layer information and exposing the second layer information. For example, where second layer information includes program guide listings, the user may then scroll along the same and/or a different axis program guide listings for NBC (in this example). The scroll may be along the same axis, may be three dimensional such as with a wheel or rolodex, and/or may be a single dimensional scroll. In one embodiment, the scroll continues along the same axis to provide a natural and intuitive progression. The user may then select second layer information such as, for example, a program listing. The selection of the second layer information may be variously configured. In one embodiment, selection of second layer information brings up third layer information e.g., in this example options to play, record, watch trailer, e-mail, link, or view additional information about the show. Additional layers such as fourth, fifth, sixth, etc. layers may also be provided. In one example, the third layer may provide information regarding the selected program listing selected from the second layer. In one embodiment, a layer may provide record, play, and/or send options. In certain embodiments, a layer may be provided such that the selected media content may be played within an area along the same axis of the previous layers. In certain embodiments, different layers may expand the axis even further. For example, when a layer is finally reached which is determined to be suitable, the axis may be expanded to include all or substantially all of the screen area. For example, where the show is finally selected to be watched, the opening along the axis may be full screen or substantially full screen.

     DETAILED DESCRIPTION 
     In the following description of various illustrative embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments in which aspects of the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made, without departing from the scope of the present disclosure. 
       FIG. 1  illustrates an example information distribution network  100  on which many of the various features described herein may be implemented. Network  100  may be any type of information distribution network, such as cable, fiber, satellite, telephone, cellular, wireless, etc. One example may be an optical fiber network, a coaxial cable network or a hybrid fiber/coax distribution network. Network  100  may be variously configured such as having one or more wired or wireless communication channels  101  (e.g., coaxial cables, optical fibers, wireless, etc.) to connect one or more locations  102  (e.g., businesses, homes, consumer dwellings, network reitems, etc.) to one or more data center(s)  103  (e.g., data center or headend). The data center  103  may transmit downstream information signals onto the channels  101 , and each home  102  may have a receiver used to receive and process those signals. 
     There may be one line  101  originating from the data center  103 , and it may be split a number of times to distribute the signal to various locations  102  in the vicinity (which may be many miles) of the data center  103 . The channels  101  may or may not include additional components. Where the communication channels  101  include additional components, these components may be such items such as splitters, filters, amplifiers. Portions of the channels  101  may also be implemented with fiber-optic cable, while other portions may be implemented with coaxial cable, other channels, or wireless communication paths. The data center  103  may include an interface  104  which may be variously configured. In one exemplary embodiment, the interface includes a modulator and a demodulator (modem). The data center  103  may include various backend devices such as processors and/or storage devices such as servers  105 - 107 . The data center  103  may also include one or more network interfaces  108 , which can permit the data center  103  to communicate with one or more networks  109  such as public, private, switched, or packet networks. Network(s)  109  may be variously configured to include one or more networks such as for example, the Internet devices, telephone networks, cellular networks, fiber networks, wireless networks (e.g., WiMAX), satellite networks, and any other desired network. 
     As noted above, the data center  103  may include a variety of servers such as one or more content server(s)  106  for distributing audio, video, and/or data content using one or more protocols. The content may be variously configured to include content such as, for example, video on demand movies, television programs, songs, text listings, etc. The content server  106  may be variously configured to include such items as, for example, software to validate user identities and entitlements, locate and retrieve requested content, encrypt the content, and initiate delivery (e.g., streaming) of the content to the requesting user and/or device. 
     The data center  103  may also include one or more application servers  107 . An application server  107  may be variously configured to offer any desired service, and may run various languages and operating systems (e.g., servlets and JSP pages running on Tomcat/MySQL, OSX, BSD, Ubuntu, Redhat, HTML5, JavaScript, AJAX and COMET). 
     In one exemplary embodiment, an application server  107  may be configured for a specific environment such as a content distribution and/or monitoring environment. An example location  102   a  may include an interface  110  which may be variously configured such as, for example, including one or more transmitters and/or receivers used to communicate with the data center using, for example channel(s)  101 . The interface  110  may be variously configured to communicate directly and/or indirectly with one or more devices local and/or remote to the location  102 (a). For example, these devices may include one or more terminals such as, for example, televisions  112 , radios, music players, computing devices, a set-top box(s) (STB)  113 , computers  114 , laptops  115 , digital video recorder(s) (DVR), computer server(s), wireless devices such as phones or tablets  116 , and/or any other desired computing device. Examples of the local network interfaces include Multimedia Over Coax Alliance (MoCA) interfaces, Ethernet interfaces, universal serial bus (USB) interfaces, wireless interfaces (e.g., IEEE 802.11), Bluetooth interfaces, etc. 
       FIG. 2  illustrates general hardware elements that can be used to implement any of the various computing devices discussed above. The computing device  200  may include one or more processors  201 , which may execute instructions of a computer program to perform any of the features described herein. The instructions may be stored in any type of computer-readable medium or memory, to configure the operation of the processor  201 . For example, instructions may be stored in a read-only memory (ROM)  202 , random access memory (RAM)  203 , removable media  204 , such as a Universal Serial Bus (USB) drive, compact disc (CD) or digital versatile disc (DVD), floppy disk drive, or any other desired electronic storage medium. Instructions may also be stored in an attached (or internal) hard drive  205 . The computing device  200  may include one or more output devices, such as a display  206 , and may include one or more output device controllers  207 , such as a video processor. There may also be one or more user input devices  208 , such as a remote control, keyboard, mouse, touch screen, microphone, etc. The computing device  200  may also include one or more network interfaces  209 , such as, for example input/output circuits with one or more external network(s)  210 . The network interface may be a wired interface, wireless interface, or a combination of the two. In some embodiments, the interface  209  may include a transmitter and/or receiver (e.g., a modem), and network  210  may include one or more of the communication channels  101 . 
     Aspects of this disclosure relate to improved systems and methods for displaying, data, such as media content information on display devices.  FIGS. 3A-B  are exemplary flowcharts of illustrative method(s) for displaying data as an expandable hierarchy of data in accordance with embodiments of this disclosure. One or more methods of  FIGS. 3A-B  may be utilized to permit a user of a device, such as a mobile portable device, to consume and/or search data such as descriptive content of media they may be interested in. For example, in step  302  the display may include a column or row with one or more first layer data (e.g., items). In exemplary embodiments, different information may be shown along a single axis such as in a row or column. In one embodiment, HBO, Showtime, and/or Disney may be shown vertically down the screen. The user may navigate down the different items and select a item. A second layer may then arise. The second layer may be disposed adjacent to, overlay, partially overlay, expand out of, and/or in a 3D relationship to the first layer. In one embodiment, the second layer may be disposed along or substantially along a similar axis to the first layer data. The user may provide a further selecting of second layer data (e.g., of an offering of content such as a movie or show). The third selection may variously create a third layer of expandable hierarchy showing further data, e.g., descriptive content and/or actions associated with the selected offerings. A third layer may be disposed adjacent to, overlay, partially overlay, expand out of, and/or in a 3D relationship to the second layer. In an exemplary embodiment, the third layer expands substantially along the same or similar axis which in certain embodiments facilitates the user keeping context of his location within the data. In this example, the third layer data may be, for example, additional information, or options selectable by the user, such as: play, record, and/or send. 
     The display of the hierarchy either vertically and/or horizontally and/or the relationship between the various layers (disposed adjacent to, overlay, partially overlay, expand out of, and/or in a 3D relationship) may be user selectable. Further, the user may select the content items and/or content within the content items. For example, the user may apply various filters such as, for example, favorite channels, favorite content providers, ratings, and/or other selection criteria to the first, second, or other layers of data. The user may further apply filters to the content within the content items e.g., a rating on the programs available for viewing and/or a category of programs. Further, the filter may be manually controlled and/or automatically adjusted based on the device configuration on which the information is presented. For example, automatic filters and/or configurations may be applied where the device is low resolution (e.g., non-HD TV), small in size (e.g., cell phone), medium in size (e.g., laptop, tablet), or large in size (e.g., television). Additionally, the filters may be stored in the cloud and/or at one or more devices. The filters may be pushed out from one device to all other associated devices, for example, with user the configuration files. For example, in the exemplary flow of  FIG. 3B , the filters may be applied based on the size of the display and the filter applied relates to the quantity of the items to be displayed at step  302   a.  The display quantity may be adjusted at step  302   b  or set to a default value step  302   c  where the display is not known. 
     In one exemplary embodiment, a hierarchy of layers may be configured to provide a selectable collection of data. The collection of data may represent a plurality of data items. In one embodiment, data items may represent content listings of media. To permit easier access to an end user, content listing (or any other type of data) may be rendered in a single column comprising a plurality of data entries along a first axis (e.g., vertical). 
     Specifically,  FIGS. 4A-4G  show an illustrative hierarchy of data, exemplified as selectable data  400  (e.g., content listings), being displayed on display device  402 . As seen in  FIG. 4A , a selectable hierarchy of data  400  may include a plurality of sequentially-arranged data  404 - 408  (e.g., items of media content), aligned along vertical and/or horizontally axis  410  of display  402 . In one embodiment, data  404 - 408  may represent items of content, such as media content listings.  FIGS. 4A-4D  show a rectangular overlay such as might be associated with, for example, a telephone. While embodiments may be employed on any display device, the elongated rectangle associated commonly with phones has particular applicability to certain embodiments particularly where a vertical axis is utilized. 
     In an embodiment in which data  404 - 408  represents items of media content, data  404  may represent video reitems available from one or more items, such as a first website and/or content provider (e.g., NBC, CBS, Yahoo, Google, or Amazon), data  406  may represent textual information accessible from the one or more items such as a second web site (e.g., HBO), and data  408  may represent one or more video reitems accessible from a third content provider (e.g., Disney). While the information shown in  FIG. 4A  may be variously configured, in exemplary embodiments it may represent first level information. There may, of course, be more first level information available than can be displayed on the screen at any one time.  FIG. 4B  shows that the first level information may be scrolled on and off of the screen and may be considered to exist behind the screen. 
     In exemplary embodiments, the first, second, and/or third, etc. level information is stored as a linked list. In still further embodiments, the first, second, and/or third, etc. level information is stored in a data array. 
     In still further embodiments, data  404 - 408  of  FIG. 4A  may represent channel listings, such as associated with a program guide. For example, briefly looking to  FIG. 4E , item  404  may represent channel 5 (“USA”), item  406  may represent channel 6 (“ABC”) and item  408  may represent channel 7 (“ESPN”), each of which may be received from one or more content provider(s). The items of media content  404 - 408  may be received through any suitable item such as a multicast media system. In yet another embodiment, item  406  may represent a first channel from a first content provider and item  408  may represent a first channel from a second content provider such as a media item. For example, item  404  may represent an high-definition (HD) movie channel from a multicast provider, item  406  may represent a music channel from an over-the-air (OTA) antenna, and item  408  may represent an interactive media channel from a third provider. One or more channels may be mapped to interactive content available from any suitable item such as, for example providers on the Internet and/or a webpage. As shown in the examples of  FIG. 4A-4B  and  4 E, data items  404 - 408  are shown as sequentially-adjacent along axis  410 . This example does not have intervening content which, in certain examples, can simplify the presentation to the user. 
     In exemplary embodiments, the layer one information represents represent channel listings available from a single content provider, layer two information represents programs on that channel, and subsequent layer information includes the ability to play the content. However, as discussed above, this disclosure is not so limited, and the examples are merely for illustrative purposes. 
     Various embodiments may determine whether an indication of the quantity of layer information (e.g.,  404 - 408 ) to be displayed has been received (see, e.g., decision  302   a  of  FIG. 3B ). In one embodiment, the quantity of information associated with a particular layer to be displayed at block  302  may be based, at least in part, on the size of the display  400 , the type of device  200 , the level of information (e.g., layer one, two, three etc.) and/or one or more software/hardware components of device  200 . For example, in one embodiment, one or more systems or methods may auto-detect that device  200  is a mobile device (or specific type, make or model of a mobile device) and determine a quantity of first, second level, and/or third level, etc. information to simultaneously display at block  302 . 
     In yet another embodiment, decision  302   a  may comprise the reception of a user input that indicates the quantity of information items, such as, channel listings to be simultaneously displayed along axis  410 . If at decision  302   a,  an indication is received (either through a user input, an automated procedure, and/or another action), block  302   b  may be implemented to display the indicated quantity of data items at block  302 . If an indication is not received at  302   a,  block  302   c  may be received to display a default value of data items. Block  302   c  may be followed by the re-execution of 302 a.    
     In one implementation, level one information (e.g., data items)  404 - 408  may be vertically accessible as a single item, such that less than all of the level one information is simultaneously viewable on display  402 . As an example,  FIG. 4B  shows hierarchy of data of selectable level one information  412 - 414  as part of the single axis of hierarchy of data of selectable content listings only some of which is on the screen. In the depiction shown in  FIG. 4B , certain level one information  412 - 414  may not be displayed due to size restrictions. In one embodiment, however, a user may touch/swipe a region of display  402  corresponding to a command to scroll up/down the column, thereby causing other level 1, 2, 3, etc., information (depending on the current active level) to fall outside of the viewable region of display  402 . In addition, level one information (e.g., channel listings)  412 - 414  may enter the viewable region of display  402  (from the top and/or bottom portion). Those skilled in the art will appreciate that a touch-sensitive display (such as for example, display  402 ), is only one example of a mechanism configured to receive a user input to vertically and/or horizontally scroll through the hierarchy of data  400  and that a user input may be received through any input device, including for example, keypad  306  shown in  FIG. 2 . 
     Further aspects of this disclosure relate to a hierarchy of data having multiple layers arranged in an expandable hierarchy of data, such as along one or more axis such as a horizontal and/or vertical axis  410 . For example, each of items  404 - 408 ,  412 - 414  may represent a first layer data that is first displayed at block  302 . Each of the first layer data, however, may be associated with second layer data (e.g., chronologically ordered media offerings that are not displayed in  FIG. 4B ). 
     In response to the selection of the displayed item, a first layer (or a portion thereof) may be expanded and a second layer may be displayed in regards to the selected first layer data (see, e.g., block  306  of  FIG. 3A ). For example, as shown in  FIG. 4C , first level data  404  may have been selected, and as a result, second layer data  415  (e.g., multiple second level data items  416 - 420 ) may be displayed. Thus, in one embodiment, the first layer (e.g., data items  404 - 408 ) may be expanded along the vertical axis  410  and second layer  415  of the expandable hierarchy of data is displayed. As shown in the illustrative embodiment of  FIG. 4C , second level  415  comprises at least a portion of the media offerings (e.g.,  416 - 420 ) associated with the selected item  404 . In one embodiment, media offerings  416 - 420  may be chronologically-ordered. 
     Further, the displayed level information (e.g., media offerings or content listings)  416 - 420  of the second layer  415  may be displayed along the same first axis  410  (e.g., vertical axis) and wherein at least a portion of two data items (e.g.,  404 ,  406 ) of the first layer remain displayed along the axis  410 . In the exemplary embodiment of  FIG. 4C , item  404  remained upon reception of the user input selecting it, however, in another embodiment, a data item, such as item  404  may not be displayed upon selection, but rather may be replaced with contents of the second layer  415 . 
     The displayed media offerings may be chronologically ordered according to a fixed timeline, for example,  416 - 420  each represent a fixed time frame, such as 30 minutes. Yet in other embodiments, the media offerings may be ordered on a relative scale such as when the shows are scheduled. For example, longer shows may occupy a slightly larger amount of room along the axis and/or be shown as slightly larger (either vertically and/or horizontally). For example, offering  416  may be scheduled to start at 6:00 and have a duration of 30 minutes and offering  418  may be scheduled to start at 6:30 and have a duration of 1 hour. Therefore, in one embodiment, despite offering  418  being twice the duration of offering  416 , it may only occupy one entry rather than two 30 minute time slots. In other embodiments, the longer offering may extend only slightly in the vertical and/or horizontal direction such as about 10%, 20%, 30%, 50% of the original listing. In yet another embodiment, the media offerings may not be chronologically ordered, but rather may be displayed in accordance to other criteria, such as viewer requests, a vote, or combinations thereof. 
     In accordance with one embodiment, the portion of media offerings (e.g.,  416 - 420 ) displayed on the second layer  415  in response to the first user input collectively form a top boundary and a bottom boundary separated by a vertical distance (such as along axis  410 ) that is substantially identical to the item  404  that was selected by the first user input. Yet in another embodiment, the vertical distance between a top and bottom boundary of the displayed media offerings may be less than the selected channel listing (e.g.,  404 ). In yet further embodiments, the vertical distance between a top and bottom boundary of the displayed media offerings may be greater than the selected channel listing (e.g.,  404 ). 
     In one embodiment, upon reception of the user input at block  304 , the first layer and the second layer collectively form a single vertically accessible item at block  306 . In another embodiment, the single column of the first layer may define a substantially uniform horizontal width between two vertical boundaries that are parallel with the first vertical axis  410 . Further, as shown in  FIG. 4C , the portion of the chronologically-ordered media offerings (e.g.,  416 - 420 ) associated with the selected item  404  displayed on the second layer  415  in response to the first user input form a column having substantially the same horizontal width as the single column of the first column. 
     In one embodiment, a user input may be specific to a single data item. For example, a user may designate that selection of item  404  may result in the displaying of 3 hours of programming, whereas the selection of item  406  may result in the displaying of 4 hours of programming. Alternatively, the selection may be specific to other criteria, in lieu of or in addition to time, such as a quantity of media offerings. For example, selecting item  404  may display 3 media offerings, whereas selecting item  406  displays  4  media offerings. 
     At block  308 , a user input may be received that is configured to select a displayed media offering (such as one of the displayed media offerings  416 - 420  of the second layer  415 ), and in response, display descriptive content of the selected media offering, such as along the same first vertical axis  410 . 
     In one embodiment, selection of a media offering at block  308  may result in the expansion of the second layer  415  along vertical axis  410  and the insertion of third layer  422  (shown in  FIG. 4D ) of an expandable hierarchy of data to be displayed (see, block  310 ). As shown in the illustrative embodiment of  FIG. 4D , channel listing  404  may have been first selected, thus causing media offerings  416 - 420  to be expanded. Media offering  420  may have been subsequently displayed, thus causing insertion and display of layer  422 . Although,  404 ,  420 , and  422  are shown as being simultaneously displayable on device  402 , those skilled in the art with the benefit of this disclosure will appreciate that this is not a requirement. In this regard, the exemplary embodiment of  FIG. 4F  shows that the selection of media offering  420  has resulted in the display of the third layer  422 , therefore, causing media offering  406  to be below the viewable portion of the screen. Further, a user may cause the collapse or removal of a layer (or portion thereof) of the expandable hierarchy of data through the provision of one or more user inputs. 
     Nonetheless, in one embodiment, upon reception of the user input of  308 , the first layer (listings  404 - 408 ), the second layer  415 , and the third layer  422 , collectively form a single vertically accessible item. In yet one embodiment, displaying of the third layer  422  may collapse or remove from viewing portions of the first layer. As further seen in the illustrated embodiment of  FIG. 4D , the third layer  422  and one or more of displayed media offerings  416 - 420  of the second layer  415  are displayed along the same first vertical axis  410 . In the exemplary embodiment of  FIG. 4D , media offering  420  remained upon reception of the user input selecting it; however, in another embodiment, a selected offering, such as listing  420  may not be displayed upon selection, but rather may be replaced with contents of the third layer  422 . In one implementation, displayed descriptive material of layer  422  to replace the selected media offering  420 , however, at least one adjacent media offering (e.g.,  418 ) of the second layer  415  along the first vertical axis  410  is retained. 
     Layer  422  may comprise descriptive content of the selected listing  420 . It may comprise summary information, series or episode information, actors, producers, or any other descriptive information. Descriptive content of layer  422  may comprise audio, video, text, or combinations thereof. In certain implementations, one or more user inputs may identify at least a portion of the descriptive content to be displayed in layer  422 . In one embodiment, a process similar to that shown in  FIG. 3B  may be implemented before block  308  to select or determine at least a portion of descriptive content to be displayed in layer  420 . In one embodiment, the identification of descriptive content may be specific to channel listing (e.g.,  404 ), media offering (e.g.,  420 ) and/or other criteria. 
     Block  310  or another process may be implemented to display a selectable action for initiating playback of the selected media offering  420 . The selectable action may be displayed in addition to displaying descriptive content of the selected media offering  420 . Playback options may comprise regular speed play, record, one or more trick play options, such as fast forward and/or rewind, and/or other options. For example, looking to exemplary layer  422 , one or more user-selectable items may be provided for initiating user-selectable actions. In one embodiment, layer  422  (and/or another layer) may comprise icon  424  and/or icon  426 . Icons  424 ,  426  may be soft buttons configured to be interacted with, such as during use of a touchscreen and/or another user input device. In one embodiment, icon  424  may be selectable to initiate playback of media offering  420  and icon  426  may be selectable to pause and/or stop playback of media offering  420 . In certain embodiments, one or more icons may be configured to initiate or alter playback of media content related to the corresponding media offering (e.g., media offering  420 ). 
     In yet another embodiment, block  308  or another process may further initiate playback of the selected media offering (or content related to the selected media offering—such as a preview) on a display region within the two vertical boundaries of the single column of the first layer. The playback may occur simultaneously with the display of descriptive material in layer  422 . 
     Descriptive content of the third layer  422  displayed responsive to the second user input (e.g., block  308 ) may comprise a top boundary and a bottom boundary separated by a vertical distance (such as along axis  410 ) that is substantially identical to the collective plurality of media offerings  416 - 420  displayed. In yet further embodiments, the vertical distance between a top and bottom boundary of the displayed layer  422  may be greater or less than the displayed media offerings (e.g.,  416 - 420 ). As discussed above, and further seen in  FIG. 4F , third layer  422  may be accessible as a single item with at least a portion of the second layer  415  and items from the first layer, such as channel listing  404 . 
     Further aspects of this disclosure relate to rendering and displaying collections of data.  FIG. 5A  shows illustrative collection of data  500 . Collection of data  500  may comprise multiple forms of data (e.g., textual data, image data, video data, and/or application data). In one embodiment, collection of data  500  may be rendered in a user-friendly manner based upon the capabilities (and/or settings of) computing device  502 . For example, collection of data  500  may comprise a layer of data, such as a first layer (see, e.g. data  504 - 508  forming an exemplary first layer). In one embodiment, collection of data  500  may be rendered to permit easier access and navigability. For example, modern websites are often configured to simultaneously provide multiple forms of media types. Depending on the capabilities, configuration, and/or user settings of a computing device, it may be difficult and impractical to render webpage data uniformly across different devices. 
     For example, looking to  FIG. 5B , exemplary website  512  may include a first video asset  514  (labeled “Video  1 ”), a first textual asset  516  and a second textual asset  518  (labeled “Text  1 ” and “Text  2 ”, respectively), and/or a first image asset  520  and a second image asset  522  (labeled “Image  1 ” and “Image  2 ”, respectively). On a first computing device operating under a first configuration, website  512  may be rendered as shown in  FIG. 5B , however, on a second computing device (or on the first computing device under a second configuration), accessing website  512  may force the user to individually zoom into each section and/or lose their location within the site to access a certain portion of the data (e.g., one or more assets  514 - 522 ). Thus, in accordance with certain embodiments, website  512  (or a portion thereof) may be rendered to be displayable as a single column comprising a plurality of data entries along a first vertical axis (see, e.g., block  302  of  FIG. 3 ). 
     As seen in  FIG. 5A , selectable collection of data  500  may include a plurality of sequentially-arranged data  504 - 508 , aligned along vertical axis  510  of display  502 . In one embodiment, data  504 - 508  may each represent a different type of data from one or more items (such as websites). In one embodiment, selectable collection of data  500  may comprise sequentially-arranged data  504 - 508 , which are rendered according to data type of assets  514 - 522  of website  512 . Flags or other electronic indicators which may be associated with various assets of webpage  512  may be utilized in the rendering of one or more assets  514 - 522 . In one embodiment, file extensions may be utilized to discern between different data types. 
     In still yet another embodiment, one or more filters may be utilized to determine whether an asset should be rendered. For example, many websites often have assets that are not undesirable in accordance with certain embodiments. Therefore, based upon one or more determinations, it may be determined to exclude one or more assets from being rendered (or categorized with assets of similar type or characteristics). In one embodiment, location of the asset, its size, file extension, and/or other attributes of an asset or the webpage  512  may be utilized in determining whether to render (or how to render) an asset. 
     In certain embodiments, the reception of a user input may select which aspects are rendered along the single axis, such as axis  510 . In one embodiment, a user may swipe in a direction not parallel with axis  510 , such as perpendicular to axis  510 , to access filtering information. Upon accessing the filtering information, the user may then be permitted to adjust what information is filtered and/or how information may be filtered. In yet another embodiment, a first layer of information (such as comprising data  504 ,  506 , and  508 ) may be provided along a first axis, such as axis  510 , and reception of a user input will cause another first layer of information to be displayed substantially along the same axis. For example, a first layer of information comprising data  504 ,  506 , and  508  shown in  FIG. 5A  may be first displayed. In one embodiment, data  504 ,  506  and  508  may each comprise data in a single category, such as “Comedy” assets. Upon reception of a user input, such as a perpendicular swiping motion, the first layer of “comedy” assets may be replaced with a different first layer of data (that does not comprise data  504 ,  506 ,  508 ). The new first layer of data, which may also be displayed substantially along vertical axis  510  may relate to a different category of assets, such as “Drama” assets. In this regard, a user may have access to multiple different hierarchical structures, each with multiple layers. 
     In one embodiment, data  504  may represent at least one video asset (e.g., asset  514 ), data  506  may represent at least one textual asset (e.g., assets  516  and/or  518 ), and data  508  may represent at least one video asset (e.g., asset  514 ) from website  512 . Yet, in another embodiment, at least one of data  504 - 508  may represent data accessible from a second item, such as a second website. In this regard, aspects of this disclosure are directed toward aggregating data from multiple items and rendering them in a more user-friendly manner. 
     The rendering of assets  514 - 522  may consider associations or commonalities among the assets. For example, video asset  514 , textual asset  516 , and image asset  520  may relate to a common theme, such as a first media offering (such as a first news story). Thus, in one embodiment, data  504  may represent an aggregation of data that includes assets  514 ,  516  and  520 . Likewise, textual asset  518  and image asset  522  may relate to a second media asset, therefore, data  506  may represent the collection of assets  518  and  520 . In one implementation, the column of first layer data  504 - 508  shown in  FIG. 5A  may be vertically accessible as a single item, for example, as described above in reference to  FIG. 5B . 
     The rendered assets may be arranged within a hierarchy of data having multiple layers, such as along vertical axis  510 . For example, the illustrative collection of data shown as elements  504 - 508  may represent a first layer (as shown in  FIG. 5A ). In one embodiment, data items  504 - 508  may first be displayed at block  302  of  FIG. 3 . The first layer (or a portion thereof) may be expanded and a second layer may be displayed in regards to the selected item (see, e.g., block  306  of  FIG. 4A ). The expansion of the first layer may be responsive to the receipt of a user input configured to select one of the first layer data elements  504 - 508 . For example, as discussed above, video asset  514 , textual asset  516 , and image asset  520  may relate to a common theme, such as a first news story. Thus, in one embodiment, data  504  may represent the collection of assets  514 ,  516  and  520 . Looking to  FIG. 5C , selection of item  504  may cause layer  524  to be displayed. Thus, in one embodiment, the first layer (e.g., data items  504 - 508 ) may be expanded along the vertical axis  510  and second layer  524  of the expandable hierarchy of data is displayed. 
     The second layer  524  may comprise at least a portion of the assets (e.g., assets  514 ,  516 ,  520  shown in  FIG. 5B ) associated with the selected first layer data, such as data  504 . In one embodiment, data  526  may comprise information regarding video asset  514 , such as for example, a caption, description, length, still image, quality or combinations thereof. In yet another embodiment, a reduced bit rate version of video asset  514  may be provided. Data  528  may comprise information regarding textual asset  516 , such as for example, the first portion or introduction located within the asset, an abstract, or any other descriptive materials. In one embodiment, data  528  may provide the entirety of asset  518 . Data  530  may comprise information relating to image asset  520 , including for example, a caption, description, size, quality, combinations thereof. In one embodiment, data  530  may comprise asset  520 , either in its original form or at a reduced size and/or quality. As discussed above, first layer data  504 - 508  may be differentiated according to other factors, including for example, media types, therefore, the above description, is merely for explanatory purposes, and not for limiting the scope of this disclosure. 
     As shown in  FIG. 5C , the displayed data  526 - 530  of the second layer  524  may be displayed along the same first vertical axis  510 . In one embodiment, at least a portion of two data elements of the first layer (e.g.,  504 ,  506 ) may remain displayed along the vertical axis  510 . In the exemplary embodiment of  FIG. 5C , data  504  remained displayed upon reception of the user input selecting it, however, in another embodiment, a selected first layer data element, such as data  504  may not be displayed upon selection of one or more of first layer data elements  504 - 508 , but rather may be replaced with contents of the second layer  524 . As discussed above in relation to  FIG. 5D , further layers may be expanded along the same vertical axis, such as axis  510 . 
     In yet further embodiments, icons may appear as part of the level  1 ,  2 ,  3 , etc., information either alone and/or along with textual and/or video information. For example, a fast forward, rewind, pause, and play video control icon bar may be inserted in, for example, a single axis program guide. In one exemplary embodiment, the lower level data (e.g., third level data) includes a video control icon bar along with video of the selected program. 
     Further aspects of this disclosure relate to creating, converting and/or modifying a 2-dimensional structure (or information within the structure) into a navigable hierarchical structure.  FIG. 6A  a shows an exemplary visual depiction of a 2-dimensional structure of data (see structure  600 ). Although structure  600  is shown as a visually depicted 2-dimensional table, in certain embodiments, structure  600  may be a logical data structure absent any visual depiction. In one embodiment, structure  600  may comprise media information, such as elements of an electronic program guide (EPG). For example, structure  600  may comprise a plurality of data items. The data items may comprise items of media content, such as items  602 - 610  (shown arranged in column  611 ). Items  602 - 610  may be received through any suitable network(s), including for example, a multicast media system. In one embodiment, item  602  may represent the first channel from a first content provider and item  604  may represent the first channel of a second content provider. In further embodiments, one or more items  602 - 610  may represent an interactive media channel from one more providers. One more channels may be mapped to interactive content available from any suitable item such as, for example, provided through the Internet and/or a webpage. 
     Each of the items  602 - 610  may be associated with one or more groups of related information, such as media offerings. For example, media offerings  612 - 620  may represent content from items  602 - 610  respectively. In one embodiment, media offerings  612 - 620  (arranged as column  621 ) may be available during a first time period, such as during a 30 minute segment, and media offerings  622 - 630  (column  631 ) may be available during a second time period. Similarly, offerings  632 - 640  (column  641 ) may be available during a third time period. In other embodiments, there may not be any associated time period that restricts access to one or more of the media offerings within content listings. For example, each of media offerings  612 ,  622 , and  632  may each be available simultaneously. Regardless of whether any timing restrictions are present, items  602 - 610  are shown as being associated with corresponding media offerings. For example, as shown in  FIG. 6A  data item  606  is associated with media offerings  616 ,  626 , and  636  (row  642 ). 
       FIG. 6B  shows a graphical depiction of an exemplary conversion of structure  600  (or a portion thereof) from a 2-dimensional structure to an expandable hierarchical arrangement. In certain embodiments, the conversion may comprise the creation of a visual hierarchical structure. In further embodiments, an existing visual depiction of structure  600  may be converted and/or modified to form the hierarchical structure. In one embodiment, principles relating to oblique projection may be utilized to display data structures. Oblique projection and/or other techniques may be utilized to display data formed or converted into multi-dimensional data as one dimensional, however, may be navigated through the multiple dimensions. For example,  FIG. 6B  shows an exemplary utilization of oblique projection on two dimensional data (rather than a physical object) to present media data in a one dimensional presentation. As further seen in  FIG. 6B , structure  600  may be converted to a vertically-arranged hierarchical structure. In one embodiment, at least a portion of the items of column  611  (items  602 - 610 ) may form a first layer, such as layer  643 . 
     Media offerings (or portions thereof) that are associated with a item may form a second layer specific to that item. For example, as discussed above in relation to  FIG. 6A , data item  606  is associated with media offerings of row  642 , therefore, in one embodiment, at least a portion of the media offerings of  642  may form a second layer (see layer  644 ) associated with item  606 . Thus, in the depicted embodiment, structure  600  has been converted to a hierarchical structure in which layer  643  forms a “top” layer that is vertically-arranged above at least one subsequent layer (such as the media offerings in layer  644 ). In this regard, the uppermost layer of data may represent the plurality of data items. In certain embodiments, whether a visual display of the hierarchy is vertically and/or horizontally arranged and/or the relationship between the various layers (disposed adjacent to, overlay, partially overlay, expand out of, and/or in a 3D relationship) may be user selectable. 
     As shown in  FIG. 6C , at least a portion of layer  643  may be visually displayed on a display device, such as device  658 . In one embodiment, device  658  may be substantially similar to device  402 . In this regard, any discussion and/or disclosure relating to device  402  and/or  FIGS. 4A-4G  may be optionally included in various embodiments of  FIGS. 6A-6E . As seen in  FIG. 6C , layer  643  may be presented as a selectable array of sequentially-arranged data (e.g., items of media content  602 - 610 ) of that layer  643 , which may be aligned along a vertical axis of display  658 . Yet in other embodiments, layer  643  may be aligned along a horizontal axis. In one implementation, layer  643  (a.k.a., level one information) may be vertically accessible as a single item, such that less than all of the level one information is simultaneously viewable on display  658 . As an example,  FIG. 6C  shows a hierarchy of data of selectable level one information (e.g., media offerings  602 - 610 ) in which only a portion of media offerings  602 - 610  is shown as being on the screen of device  658 . In the depiction shown in  FIG. 6C , certain level one information  602 - 610  may not be displayed due to size restrictions. In one embodiment, however, a user may touch/swipe a region of display  658  corresponding to a command to scroll up/down the column. 
     As shown in  FIG. 6D , further aspects of this disclosure relate to a hierarchy of data having multiple layers arranged in an expandable hierarchy of data, such as along one or more axis. For example, each of items  602 - 610  may represent discrete data of a first layer  643 . As discussed in relation to  FIG. 6B , each of the first layer data, however, may be associated with second layer data (e.g., chronologically ordered media offerings that are displayed in  FIG. 6B ). In response to the selection of the displayed item, such as item  606  a first layer  643  (or a portion thereof) may be expanded and a second layer, such as layer  644 , may be displayed in regards to the selected first layer data. For example, as shown in  FIG. 6D , first level data  606  may have been selected, and as a result, second layer data  644  (e.g., multiple second level data items  616 ,  626  and  636 ) may be displayed. Thus, in one embodiment, the first layer  644  (comprising data items  602 - 610 ) may be expanded along the vertical axis and second layer  644  of the expandable hierarchy of data is displayed. In one embodiment, media offerings  616 ,  626  and  636  may be chronologically-ordered. Similar to certain implementations of layer  643 , layer  644  may be vertically accessible, such that at least a portion of the data of layer  644  may not be viewable at all times (see. e.g.,  FIG. 6E ). 
     As shown by the illustrative embodiment of  FIG. 6F  and  FIG. 6G , the user may provide a further selecting of data of the second layer  644 . The third selection may variously create a third layer  652  of expandable hierarchy showing further data, e.g., descriptive content and/or actions associated with the selected offerings. A third layer  652  may be disposed adjacent to, overlay, partially overlay, expand out of, and/or in a 3D relationship to the second layer. In an exemplary embodiment, the third layer  652  expands substantially along the same or similar axis which in certain embodiments facilitates the user keeping context of his location within the data. In this example, the third layer data may be, for example, additional information, or options selectable by the user, such as: play, record, and/or send.
