The above and other features of the present invention, its nature and various advantages will be more apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which:
The systems and methods described herein are directed toward providing enhanced blackout functionality in video mosaic screens. Although the described embodiments may refer to Video-Rich Navigation (VRN) screens, displays, pages, and/or environments, the present invention may be used with any remotely-generated or locally-generated video mosaic screens. In addition, although the windows or cells of the mosaic pages are described herein as being populated with analog or digital video from broadcast television channels, the windows or cells of the mosaic pages may be populated with any suitable video assets or media content. These video assets may include live broadcast programs, video on-demand (VOD) assets, pay-per-view (PPV) assets, recorded assets (e.g., from a digital video recorder, or DVR), locally stored assets, advertising, websites, previews, Webcasts, interactive games and applications, or any other suitable content. The cells may contain full-motion video, audio, still images, text, icons, logos, or any combination of these (or any other suitable) elements.
VRN screen data source 14 may be any equipment suitable for generating VRN screen data. For example, VRN screen data source 14 may be a personal-computer (PC) based system or a workstation. User interface 18 may be any suitable interface, such as a Windows-based or Unix-based graphic user interface (GUI), which allows, for example, an operator to define VRN definitional files and synchronize the VRN screen data of the definitional files with content from content source 12. The user interface may allow an operator to, for example, specify transitions between distinct configuration specifications for selectable items in synchronization with video content. The user interface may also allow an operator to define control data which controls, inter alia, the appearance, functionality, and interactivity of the screen elements, as well as the content or asset displayed in a screen element.
The screen data may also include blackout information. The blackout information may be inserted into the screen data by central facility 10 (e.g., the blackout information may be generated by VRN screen data source 14) or distribution facility 20. The blackout information may be entered by an operator, may be generated automatically from another system (such as an access-and-control system), or may be generated in any other suitable manner or combination thereof. The blackout information may include, for example, one or more blackout source identifiers, blackout multicast addresses (MCAs), blackout controller identifiers, channel map identifiers, cable plant identifiers, or any other suitable information. The blackout information may also include locality information, such as a set of zip codes where the object associated with the screen data should not be presented. See
Blackout information may also include blackout time definitions. These definitions may specify, for example, that a particular blackout is in effect between 3:00 PM EDT and 6:00 PM EDT. As another example, a blackout may be linked to a specific event in a television program guide database, with its activation time equal to the start time of the event and its deactivation time equal to the end time of the event. In some embodiments, the blackout time definitions may be included with the VRN screen data. In other embodiments, the blackout time definitions may be used to determine when to include blackout information in the VRN screen data.
Distribution equipment 16 may be any suitable equipment for distributing VRN screens from content source 12 and VRN screen data from VRN screen data source 14 over communications path 19 to distribution facility 20, and further over communication path 28 for distribution to user equipment 30. Central facility 10 may distribute the screens and screen data to multiple distribution facilities 20, but only one has been shown to avoid over-complicating the drawing. In other embodiments, central facility 10 may distribute the VRN screens and screen data to users at user equipment 30 directly. Distribution equipment 16 may distribute the VRN screens and VRN screen data in any suitable analog or digital format and over any suitable communications path (e.g., satellite or terrestrial broadcast, the Internet, etc.). VRN screen data and blackout information may be distributed in-band or out-of-band from the VRN screens.
Distribution facility 20 may be any facility (e.g., a cable headend) suitable for receiving the VRN screens and screen data and distributing the screens and screen data to user equipment 30. There may be multiple users at multiple instances of user equipment 30, but only one instance of user equipment has been shown to avoid over-complicating the drawing. Distribution facility 20 may include local insertion equipment 22 and content source 24 for allowing a local operator to insert content and data into the VRN screens or VRN screen data, respectively, and compile VRN screen data into binary format for transmission (if required). Local insertion equipment 22 may run, for example, a local version of user interface 18 and compiler 20.
Distribution equipment 26 may distribute the VRN screens and VRN screen data in any suitable analog or digital format and over any suitable communications path to user equipment 30 (e.g., broadcast, cable, or the Internet.). The communication paths 19, 49, and 28 may include, for example, a satellite path, a fiber-optic path, a cable path, an Internet path, or any other suitable wired or wireless path. For example, VRN screens may be provided as MPEG-2 feeds. Distribution equipment 26 may provide the VRN screens (and the VRN screen data) as tunable analog or digital channels, or as VOD streams (both of which are referred to herein as VRN channels). The VRN channels provide the users of user equipment 30 with a set of interactive features that make up a VRN application.
In some embodiments, distribution facility 20 may provide the VRN channel full-time over a given analog or digital channel. Alternatively, distribution facility 20 may provide VRN channels on-demand or during specific time intervals.
Distribution facility 20 may provide one or more VRN applications to user equipment 30. A VRN application may include a set of VRN screens, buttons, and associated functionality. For example,
User equipment 30 may include any equipment suitable for providing an interactive media experience and for implementing the VRN applications provided by distribution facility 20. User equipment 30 may include television equipment such as a television, set-top box, recording device, video player, user input device (e.g., remote control, keyboard, mouse, touch pad, touch screen, or voice recognition interface), or any other device suitable for providing an interactive multimedia experience. For example, user equipment 30 may include a DCT 2000, 2500, 5100, 6208 or 6412 set-top box provided by Motorola, Inc. In some embodiments, user equipment 30 may include computer equipment, such as a personal computer with a television card (PCTV). In some embodiments, user equipment 30 may include a gaming system, a portable electronic device, such as a portable DVD player, a portable gaming device, a cellular telephone, a PDA, a music player (e.g., MP3 player), or any other suitable portable or fixed device.
In the example of
Control circuitry 32 is adapted to receive user input from input device 38 and execute the instructions of video mosaic client 31 and any other interactive applications running on user equipment 30. Control circuitry 32 may include one or more tuners (e.g., analog or digital tuners), decoders (e.g., MPEG decoders), processors (e.g., Motorola 68000 family processors), memory (i.e., RAM and hard disks), communications circuitry (e.g., cable modem circuitry), input/output circuitry (e.g., graphics circuitry), connections to the various devices of user equipment 30, and any other suitable component for providing analog or digital media programming and interactive media features. In one embodiment, control circuitry 32 may be included as part of one of the devices of user equipment 30 such as, for example, part of recording device 36, display device 34, or any other suitable device (e.g., a set-top box, television, video player, etc.).
Display device 34 may include any suitable device such as, for example, a television monitor, an LCD screen, a computer monitor, or a display incorporated in user equipment 30 (e.g., a cellular telephone display or music player display). Display device 34 may also be configured to provide for the output of audio and/or other sensory output (e.g., a holographic projector or virtual reality simulator).
Recording device 36 may be a personal video recorder (PVR), digital video recorder (DVR), video cassette recorder (VCR), DVD-recorder, or any other suitable recording device. Recording device 36 may include one or more tuners.
Video mosaic client 31 may be implemented on user equipment 30 as a stand alone applications or part of another interactive application, such as an interactive media guidance application (IMGA) or interactive program guide (IPG). One or more of the interactive applications may receive interactive application data from application data source 40. As shown in
Homepages (and other VRN screens or pages) delivered to user equipment 30 may include a number of interactive elements. Interactive elements may be highlighted and selected. If the user navigates to a specific interactive element (e.g., by using the arrow keys on a remote control device), the interactive element may be visually highlighted in some fashion (e.g., a colored border may appear around the element). If the user selects a highlighted interactive element (e.g., by pressing the “OK” button on a remote control device), the system may display a specific tunable channel, VOD clip, VOD screen, or another interactive application screen, based on selection behavior specified for the interactive element in the VRN screen data.
Video mosaic client 31 provides enhanced blackout functionality for VRN screens and pages. For example, video mosaic client 31 may parse received VRN screen data to determine if one or more objects in a VRN or video mosaic screen should be blacked out. In some embodiments, the blackout information in the screen data simply specifies the object or objects in the video mosaic page that should be blacked out on the user equipment. In these embodiments, each user equipment may receive different blackout information, depending on such factors as the user equipment's locality, channel map, or any other suitable information. Video mosaic client 31 may determine the location of the blacked out object within the video mosaic page and take appropriate action to blackout the object. In other embodiments, the same blackout information is delivered to all users requesting the same video mosaic page in the form of one or more blackout flag structures. Video mosaic client 31 parses the received blackout flag structures to determine if any objects in the video mosaic page should be blacked out. As described in more detail with regard to
In some embodiments, blacked out cells are not selectable by the user. For example, video mosaic client 31 may prevent user selection of blacked out cells by moving the selection cursor to the next cell that is not blacked out. In other embodiments, users may select blacked out cells. Upon selecting a blacked out cell, video mosaic client 31 may display various blackout options to the user. These options may allow a user to substitute replacement media in a blacked out cell or window, search for accessible media similar to the blacked out media, purchase tickets, obtain more information, or any other suitable action.
Although, in the illustrated embodiment of
Options buttons 306 may include single-selection access to a variety of commonly-used features. For example, options buttons 306 may link the user to the interactive media guidance application, on-demand or digital video recorder (DVR) resources, or permit the user to search for available media.
The number, location, size, and shape of the cells in display 400 may be altered without departing from the spirit of the invention. As described above, screen data may be used to define the elements in a video mosaic page. This data may define more or fewer than eight cells and cells of different sizes, positions, and shapes than those shown in
VRN display screen 400 may also include one or more of vertical option buttons 404 and horizontal option buttons 406. These buttons may link screen 400 to other VRN screens, the main IMGA screen, or perform any suitable functionality. For example, one button may select all the numbered cells in screen 400, while another button may deselect all the numbered cells in screen 400.
In some embodiments, the screen data includes unique identifying information for each cell in mosaic page 500. The video mosaic client may then use this unique identifying information to look up blackout information from a network location or content source (e.g., content source 12 or 24, both of
In one embodiment, the blackout information defines blackout flag structures including one or more source identifiers, one or more multicast addresses (MCAs), and/or one or more controller identifiers, as described in more detail in
When the video mosaic client determines that one or more elements in a video mosaic page should be blacked out, in some embodiments, the mosaic client may mask, or gray out, those elements with a graphic, icon, text, or logo. For example, blacked out cell 504 is masked with a gray box and a “Blacked Out” label. The location of the mask may be determined from the received screen data. For example, the screen data may define the x and y coordinates of each cell, the cell size, shape, and/or any other property of the cells in display 500.
The screen data may also define control data for each cell. In some embodiments, to determine whether a cell should be blacked out, the video mosaic client may compare the received blackout information to local variables on the user equipment. For example, the control data itself may include a set of conditionals that, when interpreted by the user equipment, cause the video mosaic client to retrieve one or more user equipment variables (e.g., the user's zip code or channel line-up) and determine whether a blackout applies to the particular user equipment.
The control data (also referred to herein as action data) may also define actions associated with a user selection of a cell. For example, the control data may instruct the video mosaic client to link the user to a broadcast channel or to order a VOD or PPV asset upon the user selection of a cell. For blacked out cells, the cells associated control data may be redefined or supplemented by the video mosaic client so that one or more new actions are defined upon a user selection of a blacked out cell. For example, as shown in display screen 800 (
For example, the video mosaic client may override a mosaic template definition by applying a new template to the video mosaic page. The new template definition may globally redefine the action data associated with each object in the video mosaic page that is determined to be blacked out on the user equipment. For example, the new template may overwrite the existing control data relating to each blacked out object in the video mosaic page and define a new series of prompts to be displayed upon user selection of a blacked out object.
In addition to masking the area of a blacked out cell in display screen 500, the video mosaic client may also block the audio associated with any blacked out cell. Blacked out elements in a video mosaic page may also be automatically replaced with substitute media. In some embodiments, the media substitution may be performed locally by the video mosaic client. In other embodiments, the substitution is performed at a local cable headend or other distribution facility, such as distribution facility 20 (
If the substitution is performed locally by the video mosaic client, locally-stored video, advertising, and graphics may be used as the replacement media and presented in the mosaic page. Additionally or alternatively, the video mosaic client may substitute any content currently accessible by the user equipment with the blacked out content. For example, broadcast programs, on-demand programs, PPV programs, or media recorded to a local storage device (e.g., recording device 36 of
In some embodiments, blacked out elements in a video mosaic page are removed from the page before presentation of the page to the user. The video mosaic client may then dynamically recreate or re-render the mosaic page without the blacked out elements, if desired. As shown in
If blacked out cells are completely removed from the page, and the page is re-rendered with a change in position of the remaining cells, the video mosaic client may map incoming screen data and control data to the location of the new cells. Because the incoming screen data may incorrectly reflect the old location of the cells, the video mosaic client may maintain a table of the original cell locations and the new cell locations. In this way, the mosaic client may associate incoming screen data with the correct cell in the newly rendered page. If the blacked out cells are removed without a change in location of the remaining cells, the video mosaic client may simply ignore or drop any screen data received for the removed cells.
Upon selecting option 804, the user may be presented with replacement media listed in replacement media selection 805. In some embodiments, the user may select replacement media selection 805 to be presented with one or more other options for replacement media. In the case of an affiliate protection blackout, the replacement media may be the same event as broadcast by the locally-authorized network. After the user selects option 804, the replacement media identified by replacement media selection 805 may be substituted in the selected blacked out cell. In other embodiments, upon selecting option 804, the user exits the mosaic application and is tuned directly to the selected replacement content.
If the user wishes to locate other media content similar to the content in the blacked out cell, the user may select option 806. Upon selecting option 806 the video mosaic client may access interactive application data, such as interactive media guidance application content listings, and search the data for media similar to the media listed in title area 801. Similar content may be found, for example, by initiating a title search of keywords included in the title listed in title area 801. The video mosaic application may also use other media information, such as actor, director, and genre information (also derived from media guidance application data), in order to construct a search string. In some embodiments, this search string may be presented to the user. The user may then refine the search string by adding or removing search criteria, as desired. To determine the similarity between media, a distance may be calculated between other media content and the blacked out content. The distance may represent the similarity between the media. For a description of systems and methods that determine the similarity between media content using distances, see U.S. patent application Ser. No. 11/324,147, filed Dec. 29, 2005, which is hereby incorporated by reference herein in its entirety. The results of the similar media search may be presented to the user in one or more display screens or overlays, such as overlay 902 (
In some embodiments, to locate other content for a media search, video mosaic client 31 (
The user may also request more information about the blacked out media content by selecting option 808 in overlay 802. This option may link the user to one or more display screens or overlays containing a detailed description of the blacked out content, the length and reason for the blackout, and any other suitable information. In the example of
As described above, upon selecting search option 806, the video mosaic client may link to interactive application data, such as media listings information, to search for media similar to the blacked out media, or the video mosaic client may access a predefined set of similar media content in the VRN screen data. As shown in
In some embodiments, the content listed in overlay 902 is currently accessible by the user equipment (e.g., currently being broadcast). In other embodiments, media content that will soon be accessible may also be listed in overlay 902. For example, broadcast content that will be broadcast within the next 15 minutes may be included in the overlay. In addition, the search results listed in overlay 902 may exclude any blacked out content or content otherwise locked and/or inaccessible by the user equipment or the current user logged on to the user equipment. For example user-based parental controls may be defined on the user equipment. Content exceeding one or more parental control locks for the user may be excluded from the search results even though the content may match the search string or search criteria. In this way, the user can be assured that any media content listed in search results overlay 902 is actually accessible and viewable by the current user.
The content listed in overlay 902 may include broadcast content, such as shown in listing 904. Internet websites may also be searched and listed in overlay 902, as shown in listing 906. Websites, like other content, may be searched by genre, title, or any other suitable characteristics. In the example of
Some or all of the listings in overlay 902 may be associated with source identifiers, such as identifiers 908 and 912. These source identifiers may indicate the channel or source of the content listed in overlay 902. Some example source identifiers may include “VOD” for video on-demand assets, “PPV” for pay-per-view assets, “NET” for assets available on the Internet (or a private network), “DVR” for recorded assets, “APP” for interactive applications, “GAME” for interactive games, and “MUSIC” for digital music accessible from the user's music library.
In response to selecting a listing in overlay 902, the user may be tuned directly to the selected content. If the content is not currently accessible, the user may be tuned to the appropriate channel where the content will shortly become available. Additionally or alternatively, the selected blacked out cell in the video mosaic page may be replaced with the selected content. The cell may then present the selected content in full-motion video. Upon substituting replacement media in the blacked out cell, the video mosaic client may also redefine action data associated with the cell so that the cell now behaves like any other non-blacked out cell. In some embodiments, the user's selection of replacement media may be remembered (e.g., saved to memory) for the duration of the blacked out event, even if the user tunes away from and then back to the video mosaic page.
The video mosaic client may parse screen data in order to identify the elements in a video mosaic page. Each “chunk” of screen data may be associated with a specific video asset in a video mosaic page or with any other set or subset of the screen data. For a further description of the screen data chunks and an illustrative object definition, see U.S. patent application Ser. No. 11/395,380, filed Mar. 30, 2006, which is hereby incorporated by reference herein in its entirety.
In general, the video mosaic client needs only some identification of the source of the objects being presented in a video mosaic page and a set of blackout rules to effectively blackout mosaic objects. However, because blackouts are often time-based, maintaining a complete set of blackout rules on the user equipment may require frequent updates and a large amount of bandwidth. Therefore, in some embodiments, a blackout flag structure is used that approximates the blackout rules. For example, blackout rules for National Football League games may require that any broadcaster that has a signal that reaches within a 75-mile radius of an NFL stadium blackout all games at the stadium that are not sold out 72 hours or more before the start of the game. Other, more complex blackout rules may also apply. By using the blackout flag structure described below, the video mosaic client can estimate these complex rules and enforce the programming blackout.
In the example of
By providing a list of blackout source identifiers, blackout multicast addresses, and blackout controller identifiers in the screen data, the video mosaic client may determine if any cells or other elements in a video mosaic screen are blacked out using three separate criteria. Other data may also be included in the blackout flag structure to increase the number of blackout criteria, if desired. For example, locality information (e.g., zip codes and/or geographic coordinates) may be specifically provided in the blackout flag structure. If the user equipment has a local zip code or geographic coordinates variable set, this information may be used to determine if the object in the mosaic page should be blacked out. For example, a global positioning system (GPS) or similar system may automatically update latitude and longitude coordinate variables stored in the user equipment. In these embodiments, a GPS receiver (not shown) may be integrated with user equipment 30 (
Because the control data stream may be time-synchronized (e.g., a real-time data stream), the video mosaic client may the parse blackout flag structures as new flags are received. Alternatively, the video mosaic client may parse the blackout flag structures at regular intervals (e.g., every 1 minute). If the blackout information in the control data indicates that the object associated with the blackout flag should be blacked out, the video mosaic client may take any of the actions described above to black out the object. If at some point the blackout data in the control data stream changes to indicate the object is no longer blacked out, the video mosaic client can reverse the steps taken to restore the original object. In some embodiments, the blackout flag structures may include the time parameters (e.g., the activation time and the deactivation time) of the blackout. In some embodiments, the time parameters may be omitted under the assumption that the blackout flag structures will be changed at the start and end of the blackout.
The blackout source identifiers included in the blackout flag may indicate one or more blackout channels or sources. For example, the source identifiers corresponding to the channels ESPN and the YES network may be listed as source identifiers in the blackout flag. If at least one of the source identifiers matches any source identifier in the local channel map on the user equipment, the video mosaic client may blackout this object. For example, affiliate protection blackouts may require that one or more local broadcasters have the sole right to broadcast a sporting event. In this example, the source identifiers for the local broadcasters may be specified as blackout source identifiers in the blackout flag structure. Then, if the sporting event is also being presented in a video mosaic page (such as a sports genre mosaic page) as part of a national feed, the video mosaic client may blackout this object.
The blackout multicast addresses included in the blackout flag may indicate one or more network multicast addresses (e.g., IP multicast addresses). If the user equipment is joined to any multicast addresses in the blackout multicast list (or configured to send or receive data at a multicast address in the blackout multicast list), the object associated with the blackout flag structure may be blacked out. For example, one or more multicast address may be associated with a cable headend or network access point. The user equipment may be configured to receive video streams, VRN pages, or screen data at the specified multicast address. In some embodiments, the multicast addresses on the user equipment may be indicative of the user equipment's location. For example, upon powering up user equipment 30 (
The blackout controller identifiers included in the blackout flag may indicate one or more unique blackout controller identifiers. For example, user equipment 30 (
Any other suitable information may be included in the blackout flag structures in other embodiments. For example, the blackout flag structures may include any of the following information: whether the object can be highlighted if its associated content is blacked out; whether to block the object's associated audio; whether the object can be selected if blacked out; whether to automatically provide replacement media; what to display if the object is blacked out (e.g., solid overlay, icon, text, graphic, video); reference to replacement media; one or more lists of similar media content; search criteria for similar media content; whether to automatically display a list of replacement options to user; substitute actions to perform if the object is selected while blacked out; or any other suitable information for determining if the object is to be blacked out and its behavior when displayed, highlighted, or selected if the object is blacked out.
If blackout information is defined at step 1106, the information may be parsed at step 1108. For example, blackout flags in the form of flag structure 1000 (
The object's control data may also be redefined at step 1112 so that one or more new actions are associated with the blacked out object. For example, the object's control data may be redefined so that options overlay 802 (
In practice, one or more steps shown in process 1100 may be combined with other steps, performed in any suitable order, performed in parallel (e.g., simultaneously or substantially simultaneously) or removed.
After the object associated with the blackout flag is blacked out at step 1210 or the mosaic client determines that either the blackout source identifier count is zero (step 1204) or the blackout source identifier is not present in the local channel map (step 1208), the video mosaic client may next determine if the blackout MCA count is nonzero at step 1212. In some embodiments, after determining that the object is to be blacked out for any reason (e.g., a source identifier in the blackout flag structure matches a source identifier in the local channel map), the mosaic client may stop looking at other blackout criteria. To determine if the blackout MCA count is nonzero, the value of blackout MCA count 1008 (
After the object associated with the blackout flag is blacked out at step 1218 or the mosaic client determines that either the blackout MCA count is zero (step 1212) or the blackout MCA does not match a user equipment MCA (step 1216), illustrative process 1200 may continue in
After the object associated with the blackout flag is blacked out at step 1308 or the mosaic client determines that either the blackout controller identifier count is zero (step 1302) or the blackout controller identifier does not match a user equipment controller identifier (step 1306), the video mosaic page may be presented at step 1310. For example, mosaic display 300 (
In practice, one or more steps shown in process 1300 may be combined with other steps, performed in any suitable order, performed in parallel (e.g., simultaneously or substantially simultaneously) or removed.
The mosaic client may search for similar assets based on any suitable search criteria. For example, a search string may be automatically created containing the genre and title of the blacked out object. Other content in the same genre and similar to the blacked out title may be located, for example. At step 1410 the mosaic client may determine if the located content is currently accessible by the user equipment (or will become accessible within some user-specified period of time). For example, the content may be locked by parental controls or may itself be blacked out. The mosaic client may continue searching until a predetermined number of accessible similar assets are located or until the expiration of some search timeout value (e.g., 5 seconds). If any located content is accessible by the user equipment, a search results list is populated and presented to the user at step 1412 containing the located content. For example, search results overlay 902 (
Upon selecting a search result at step 1412 or choosing not to search for similar assets, the video mosaic client may present replacement content in the blacked out cell at step 1414. For example, the content selected by the user at step 1412 may be presented in the blacked out cell. Alternatively, the mosaic client may automatically substitute the content in the blacked out cell with replacement content, as shown in cell 702 of
In practice, one or more steps shown in process 1400 may be combined with other steps, performed in any suitable order, performed in parallel (e.g., simultaneously or substantially simultaneously) or removed.
At step 1502, a blackout function call may be received. For example, an application or process external to the video mosaic client may generate a blackout request. At step 1504, the video mosaic client may determine the location of the object reference in the blackout request. For example, the object's x and y coordinates, size, and/or shape in the mosaic page may be read from screen data. At step 1506, the mosaic client determines if the object to be blacked out should be hidden or replaced. If the object is to be hidden, the mosaic client may hide the object with an overlay or other suitable cover at step 1508. For example, cell 504 (
Alternatively, the object may be removed from the page and optionally replaced with substitute content instead of using a cover or overlay. At step 1510 replacement content is located. For example, the video mosaic client may call one or more API function calls to interface with a media guidance application database to locate content similar to the content in the blacked out object. After locating suitable content at step 1510, the video mosaic client may replace the blacked out object with the substitute content at step 1514. The object's x and y coordinates, size, and/or shape in the mosaic page may be read from screen data and the newly located content may be presented at the location of the blacked out content.
After hiding a blacked out object with a cover or overlay at step 1508, the mosaic client determines if the object's associated audio should also be blocked at step 1512. For example, an MSO may be permitted to provide audio for a blacked out object (but not its video). If the audio should be blocked, at step 1516 the video mosaic client may also mute the object's associated audio. If the mosaic client determines that the audio should not be blocked at step 1512 (or if there is no associated audio) or after muting the audio at step 1516, the video mosaic client determines if replacement actions should be defines for the object at step 1518. For example, in some embodiments, blacked out objects may not be selected like other objects in the mosaic page. Rather, the cursor may skip blacked out objects, preventing them from being highlighted. If a blacked out object (or the replacement content) may be selected by the user, one or more additional actions may be defined or redefined in response to the user selection of the blacked out cell. The video mosaic client may redefine the control data associated with the blacked out object at step 1520. For example, the object's control data may be modified to present blacked out options overlay 802 in response to the user selection of a blacked out object. At step 1522, the blacked out process is complete and the object is presented to the user.
In practice, one or more steps shown in process 1500 may be combined with other steps, performed in any suitable order, performed in parallel (e.g., simultaneously or substantially simultaneously) or removed.
The above described embodiments of the present invention are presented for purposes of illustration and not of limitation, and the present invention is limited only by the claims which follow. For example, although this invention is described in conjunction with a remotely-composited mosaic of video cells, the advantages of this invention can be applied equally to other types of content on a composited screen, such as menu items, logos, text fields, and the like. This invention may also be applied to locally-composited screens or portions of screens.
