1. The Field of the Invention
The present invention relates to a dimmable user interface. More particularly, the present invention relates to systems, methods and computer program products for selectively dimming a user interface to allow for simultaneous display of the user interface with other content and more particularly to simultaneously displaying the user interface and a television program in the same window.
2. Background and Relevant Art
Today, people are able to access and surf the Internet using, for example, a television set and a set top box. These set top boxes typically require minimal computer knowledge yet they provide users with many of the same advantages that are attainable over traditional computers. A user can send and receive email messages, engage in instant messaging, chat, and surf the web using a set top box coupled with a display device such as a television set.
By connecting to the Internet through a computer or other processing device such as a set top box, users are able to perform many different functions. A user, for example, can check the traffic reports, view the latest news developments, print articles, shop, order tickets, listen to radio stations, view movie trailers, and the like. Users are often only restricted to the speed of their connection with the Internet.
Set top boxes, however, are not limited to providing users with access to the Internet. Some set top boxes, for instance, have the ability to digitally record television programs, which gives users flexibility regarding the television programs that they view. Programs are often recorded using electronic program guide (EPG) data that can be searched and viewed by the user. Once a program is identified from the EPG data, the set top box can be instructed to record that program. In addition to recording programs, set top boxes also permit users to set reminders, quickly retrieve recorded programs, fast forward through recorded programs, and other features that provide users with control over what they want to watch on the television set.
Another advantage of some set top boxes is the ability to let users directly interact with certain, enabled programs. For example, users may be able to participate with their favorite game shows, see local weather conditions during the weather forecast, access sports statistics during sporting events, research breaking news stories during the news hour, and the like while watching television. Set top boxes combine television programming with Internet data to provide more informative and entertaining television.
In spite of all the advantages provided by of set top boxes, providing interactive television is not without problems. Generally stated, the screen area of display devices becomes a scare resource when it is shared between multiple applications. In other words, the ability to display television programs and other content such as Internet data including interactive content must be balanced on the screen of the television set. This problem is significant because most people enjoy the advantages and functionality provided by set top boxes and do not want to turn those features off in order to watch a television program on a full screen.
Displaying data or other content associated with interactive television or with other set top box applications simultaneously with a television program limits the space that is available for displaying the television program. In other words, the television picture is minimized into a defined window and that small window is surrounded with interactive television controls or other content. As more interactive controls or content are added to the screen, the size of the television window will necessarily become smaller. At some threshold, the television window will still be visible, but watching television may not be enjoyable for the user. In this case, the user is faced with a choice. The user will either watch television in a small window or forego some of the advantages provided by the user interface that surrounds the small window.
Another approach is to provide a translucent overlay on top of a full screen television window that appears and disappears at the user's direction. In this case, the user's ability to view television is often distracted by the translucent overlay. Alternatively, the user can turn the overlay off and thus lose the advantages of interactive television, for example. For example, a user may be watching a sporting event while the overlay displays data related to other events. If the user turns the overlay off, then the user will not be able to interact with the sporting event. Alternatively, the overlay may interfere with the user's enjoyment and view of the current television program.
These and other problems are overcome by the present invention, which is directed to a user interface on a display device whose transparency is dynamically controlled by a user. The screen area of the display device is a scarce resource and the present invention overcomes the need to allocate the screen between content such as a television program or other video stream and content such as Internet data or interactive content. Therefore, in accordance with the present invention, a user is provided with the ability to control the visibility or transparency of a user interface or of portions of the user interface. The present invention also allows a user to control the visibility or transparency of the user interface and a video stream simultaneously.
A user interface is provided that can be simultaneously displayed with a video stream such as a television program in the same window as the video stream. The video stream may be displayed using all of the available display area of the display device. The user interface is also displayed on the display device, but the visibility or transparency of the user interface and/or the video stream is controlled by the user.
The ability to control the transparency or visibility of the user interface and/or the video stream ensures, for example, that the user is not distracted by the user interface when viewing the video stream. At the same time, the user interface is able to provide the user with content or data that would otherwise be unavailable to the user if the user interface were not present. At any time, the user can change the transparency of the user interface and/or the video stream for any reason. Another advantage of the present invention is the ability to control the transparency of selected items or content included in the user interface. This enables, for example, content along a certain portion of the display device, such as a border, to have no transparency, whereas items or content that are displayed more centrally on the display device can be configured to be more transparent. The transparency of the video stream/user interface is achieved by mixing the pixel data representing the video stream with the pixel data representing the user interface using an alpha value to control the relative strength or contribution of the respective pixel data.

The present invention relates to a dimmable user interface. More particularly, the present invention relates to a user interface whose transparency or visibility is controlled by a user. The present invention also relates to simultaneously controlling the transparency of a video stream while controlling the transparency of a user interface. The variable transparency of both the user interface and/or the video stream allows the user interface to be simultaneously displayed with data such as a television program or other video stream, for example. Thus, the user is able to use and view the links, controls and other content presented through the user interface while viewing a video stream or other content.
One advantage of the present invention is that it eliminates the need to balance the available screen area of the display device between the television program and the user interface (as shown in
The set top box 100 uses the Internet 114, for example, to surf the Web, send/receive email, chat, video conference, instant message, and the like or any combination thereof. The Internet 114 is also used in some instances for interactive television programs. Over the satellite system 116 and the cable system 118, the set top box 100 receives television content or programming content. In some instances, other content such as radio or music content is accessible through these sources. It is understood that other types of content may also be accessed or delivered through these and other sources.
The set top box 100 of
The set top box 100 and/or the display device 120 are controlled with an input device 122. The input device 122 may be a keyboard, a remote control or other device that permits a user to interact with the set top box 100 and/or the display device 120 and that permits a user to send instructions to the set top box or the display device. The set top box 100 includes a storage 102, which may be a hard drive or other memory.
The set top box stores, for example, EPG data 104 and programs 106 on the storage 102 as well as applications that can access and use the data stored on the set top box. The EPG data 104 typically contain information about television programs and includes, but is not limited to, program titles, program channels, program duration, program start and end times, and the like or combinations thereof. The stored programs 106 are often recorded from the video content delivered by the satellite system 116 or the cable system 118. This enables a user to use their set top box to record various television programs for later viewing, for example.
With interactive television 110, Internet access 108, digital recording 112, and other functions or capabilities of the set top box 100, a user is able to pause and record television shows, search the EPG data using a variety of parameters and record shows based on those parameters (by show type, title, actor, etc.), search the Internet while watching television, listen to the radio, interact directly with a television program that is currently being watched, and the like or any combination thereof. It is understood that these are exemplary abilities or functions of a set top box, and the set top box described herein is not limited to these abilities and functions.
The transparency that the user adjusted is often related to a cursor, selector or other visual indicator that identifies the content that is currently selected. When the transparency of a particular item is being adjusted as described herein, the cursor or selector can identify that item. Alternatively, the user input that represents a change in transparency can be applied to the entire user interface/video stream.
Alternatively, the present invention contemplates those situations where the transparency of one layer is controlled independent of the other layer. For example, the video stream may always be visible at a certain level, while the user can adjust the transparency of the user interface or vice versa.
In
In
A user interface whose transparency is variable can be applied to other aspects or functionality of the set top box and is not limited to the EPG data. For example, Interactive television also benefits from a dimmable user interface. A user is able to access and surf the Internet while watching a video or a television program. A user will be able to access the Internet to retrieve statistics, for example, while watching a sporting event. The user will be able to research news stories as they happen using interactive television technology. A user will be able to schedule the set top box to record a program on a different channel while watching a current program. These tasks and more can all be accomplished without having to resize the video window.
The user interface can be dimmed at the user's discretion. The ability to have a dimmable user interface overcomes the limitation of balancing the screen between the video and the user interface. In this example, the user interface is always present and can be made more visible or less visible as needed. However, the present invention does not require the presence of the user interface. A user, for example, may simply be watching television through the set top box.
The user has not dimmed the item 304, however. One reason may be that the item 304 does not interfere with the user's view of the video 302. In one example, the item 304 may be a stock ticker or may provide scores of sporting events that have been specifically identified by the user. The user interface of
The video decoder 408 decodes a program from the video input 404. The video decoder 408 also generates pixel data that is stores in a buffer 416. A mixer 410 generates screen data by combining the pixel data stored in the buffer 416 with the pixel data stored in the buffer 414. Because the buffer 414 represents pixel data of a user interface, the buffer 414 is more static and may be utilized by the mixer 410 more than once. The pixel data in the buffer 416, however, is likely representative of a single frame and is continually changing to reflect the newly decoded frames received from the video decoder 408. The screen data generated by the mixer reflects the user input 402. If the mixer 410 is capable, for example, of generating 256 levels of transparency (assuming that alpha is between 0 and 255), then the screen data is a combination of the buffer 414 and the buffer 416 as follows: ((buffer 414*alpha)+(buffer 416*(256−alpha))). The alpha value can be applied to particular pixels or groups of pixels or can be applied to the entire buffer. It is understood that the present invention is not limited to 256 levels of transparency as illustrated in this example. It is also understood by one of skill in the art that a buffer may not be required in some instances and the pixel data may be written or sent to the mixer 410 directly. In this manner, the screen data is generated by combining the pixel data of the video input with the pixel data of the user interface. In other words, the screen data is generated by mixing the user interface with a video stream and the ability to view either the user interface and/or the video stream is dependent on the respective levels of transparency that are determined from the alpha values. When the level of transparency of the user interface is adjusted, the level of transparency of the video stream is simultaneously adjusted accordingly.
While
The screen data generated by the mixer 410 is displayed on the display device 420. Often, a level of transparency for the user interface is already present and available to the set top box. This level of transparency is usually applied to the user interface. At the same time, in one example, a level of transparency is also applied to the video stream 302. The levels of transparency of the user interface and the video stream are connected and change as described previously. Thus, when the user is increasing the transparency of the user interface, the transparency of the video is implicitly changing as well.
The user input 402, which is often received from an input device such as a remote control, is added to the mixer 410. The user input 402 is used by the mixer 410 to adjust the transparency of the user interface and/or the video stream. By providing the user input 402 to the set top box 400 or to the mixer 410, a user can adjust the transparency of the user interface on the video as shown with reference to
The user also has the ability to adjust the transparency of individual items or elements of the user interface. After the user selects an item, the level of transparency for that item can be adjusted. In one example, the global level of transparency for the user interface is unchanged in this case.
The transparency of the user interface or of selected portions or elements of the user interface can be controlled using various methods. In many situations the set top box receives user input via an input device. In one example, an onscreen transparency control is provided through the user interface. In one embodiment, the transparency control represents a balance between the transparency of the user interface and the video stream. As the balance control is altered the transparencies of the user interface and the video change accordingly. If the user, for example, increases the transparency of the user interface, the transparency of the video stream is decreased and vice versa using the transparency control. In this scenario, the existing navigation buttons of an input device change the on screen selection to the transparency control icon. Once the transparency control is selected, the scroll up/down buttons, for example, can be used to adjust the transparency of the user interface/video stream or of selected items or elements in the user interface.
In another example, selected buttons on the input device can be altered or programmed to perform additional functions. For example, some buttons like a mute button, are press and release buttons. A user presses and releases the mute button in order to mute the audio. Currently, pressing and holding the mute button does not perform any function. However, this functionality can be added such that pressing and holding the mute button would increase/decrease the transparency of the user interface/video stream. Another button on the input device could be similarly altered in order to work in tandem with the mute button to decrease/increase the transparency of the user interface/video stream.
Alternatively the function of a pair of buttons on the input device could be changed according to context. For example, the volume button may be used to increase/decrease the transparency of the user interface/video stream instead of adjusting the volume when the set top box is in the context of adjusting the transparency of the user interface. Another solution is to add additional buttons to the input device that control the transparency of the user interface/video stream.
In another example where the input device is, for example, a computer mouse, controlling the transparency can be achieved by moving the cursor to a corner of the screen and using the scroll wheel. Alternatively, an extra button on the mouse can be depressed while the scroll wheel is used to control the transparency. In other situations, a button can be programmed to control the respective transparency of the displayed data.
The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
