1. Field of the Invention
This invention relates generally to media applications, and in particular to user interfaces for viewing and controlling video programs received on a portable device or a device otherwise having limited screen space.
2. Background of the Invention
Television and other video content are increasingly finding a home on mobile computing devices, such as mobile phones, personal digital assistants (PDAs), and personal video players (PVPs). For example, television programming is no longer found solely on the television. Through computer networks, as well as other delivery mechanisms, television and other media content are increasingly becoming available on these mobile computing devices.
Mobile computing devices generally have smaller screens than traditional televisions and computer monitors due to these devices' mobility. This restriction in size also tends to limit the display resolution of the screens. A common screen size for a portable device that can display video streams is 2.5-inch by 2.5-inch. When a user watches video on such a small screen, it is hard to design an effective interface for the user to control the program playing the video or executing other commands on the device.
One conventional approach to provide video control is by displaying visual controls (e.g., a control menu) on the screen. However, the menu structure may unduly conceal the video screen which may be showing active video. The menu structures are also unfriendly to users, as they force the user to search for the control commands in the menu hierarchy.
Another conventional approach to solve this problem is to dedicate control functions to certain hard buttons or keys (i.e., similar to a “speed dial” mechanism, where a command “Channel Up” can be achieved by pressing the number “3” on a keypad). However, these designations force the user to remember the designation (or at least look up the designation, such as via the same menu system) and are thus less user friendly than desired.
Accordingly, there is a need for a better user interface to allow users of mobile computing devices to control video programs viewed on those devices.
Embodiments of the invention provide a user interface for users of computing devices to control video content displayed on the computing devices. In one embodiment, while displaying a video stream, a computing device displays an overlay of a command menu on top of the active video stream. The device may display this menu overlay in response to an active request therefor by the user or in response to some other event. The command menu includes a set of commands for controlling the video stream, and the commands may each be associated with a key or other input item of the mobile computing device. A user can then select a command on the menu by pressing the associated key. The device may then use the selected command to affect the video stream according to any suitable method.
In one embodiment, the commands on the menu are displayed on the screen of the device in an orientation that corresponds to the positions of the keys associated with the commands. In another embodiment, the commands are displayed next to representations of their associated keys.
a) and 3(b) illustrate examples of user interfaces for receiving a control command to control a video program, in accordance with embodiments of the invention.
One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein.
Embodiments of the invention provide users of mobile computing device a mechanism to control video applications (or programs) on the mobile computing device. A menu of commands is displayed as an overlay on the live video content being played on the screen, thereby reducing the impact on the user experience in viewing the video content and also making the control of the video content more convenient and intuitive for the user.
In one embodiment, the commands are associated with keys on the mobile computing device. Therefore, a user can select a command by pressing (or triggering) the key associated with the command. The commands can be displayed in positions corresponding to the positions of their associated keys. In this way, a user can identify the key associated with the command of interest by the display position of the command. Alternatively, the commands can be displayed together with representations of the associated keys.
Referring to
The processor 110 may be any general-purpose processor such as an INTEL x86, SUN MICROSYSTEMS SPARC, or POWERPC compatible-CPU. The storage device 160 is, in one embodiment, a hard disk drive but can also be any other device capable of storing data, such as a solid-state memory device. The memory 150 may be, for example, firmware, read-only memory (ROM), non-volatile random access memory (NVRAM), and/or RAM, and holds instructions and data used by the processor 110. The network interface 140 couples the system 100 to a local network (e.g., a home network) or a remote network (e.g., the Internet). The bus 120 is an electrical conductor that serves as an electrical pathway along which signals are sent from components connected to the bus. The display 170 is an output screen on which visual information is displayed. The display 170 can be a touch-sensitive screen which users can interact with the system 100 by touching the display 170. The keyboard can be a 3×4 keypad standard for touch-tone telephones, a QWERTY keyboard, or any other types of keyboard. In many instances the system 100 lacks one or more of the elements shown in
As is known in the art, the computer 200 is adapted to execute computer program modules (or programs). As used herein, the term “module” refers to computer program logic and/or data for providing the specified functionality. A module can be implemented in hardware, firmware, and/or software. In one embodiment, the modules are stored on the storage device 160, loaded into the memory 150, and executed by the processor 110.
The system 100 can also optionally include an input interface (not shown) to connect to external devices such as a place-shifting system, a time-shifting system, a personal video recorder (DVR), a personal broadcaster, and a video camera. Detailed description and embodiments of a place-shifting system and a personal broadcaster can be found in U.S. patent application Ser. No. 11/147,664, filed on Jun. 7, 2005, which is hereby incorporated by reference in its entirety.
The input interface can also connect to analog cable or antenna and receive radio frequency signal (RF signal) from them. Because an RF signal includes a number of video signals modulated therein, the input interface can be coupled to provide the RF input to a tuner (not shown). The tuner filters the RF signal for a selected channel, demodulates the channel, and converts the signal into separate analog video and audio for further processing by the processor 110. The connection between the external devices and the system 100 can be either wired connection (e.g., cable) or wireless connection (e.g., Bluetooth).
The process illustrated in
The video program being displayed can be from multiple sources. As described above with reference to
The system 100 receives 220 a user command to bring up a menu. The user can input the command by pressing a key in the keyboard 130, or touch a screen if the display 170 includes a touch-sensitive screen. The key can be a soft key or a designated key. A soft key is a key located below the display 170 and linked to the bottom section of the display 170. It performs whatever function is listed on the display 170. A designated key can be any key on the keyboard 130 that is designated by the video program to bring up the menu. For example, the designated key can be the key “#”. In one embodiment, the user can toggle on and off the overlaid menu by pressing the same key.
The menu can be a control menu of the software displaying the video program. For example, the items in the menu may comprise commands such as pause, fast backward, fast forward, previous and next. Alternatively, the menu can include commands that is related to the system 100 (e.g., power off) or external devices (e.g., requesting the media source to transmit the next video program unit to the system 100). The commands can be discrete commands, or they can be macros (a series of commands strung together to execute an action). For example, a command might be labeled “CNN.” This command might act as a “bookmark” to bring the user to the Channel CNN. E.g., the keys “2,” “0,” “2” might be executed in succession if the channel number for CNN is 202. In some embodiments, commands in the menu can bring up submenus.
The system 100 overlays 230 the menu over the video program as the video program is displayed alive on the display 170. In one embodiment, the background of the commands on the menu is transparent, minimizing the video program being blocked by the overlaid menu. In another embodiment, the commands on the menu are displayed semi-transparently, rather than in solid color. Therefore, users can have the complete view of the video program with the menu overlaid on top.
In one embodiment, commands (or menu items) in the menu are assigned to keys on the keyboard 130, and displayed in positions mapping to the key assignments. One example of this arrangement is illustrated in
Table 1 illustrates the commands as they are displayed on the screen. Table 2 illustrates the layout of the keyboard. As illustrated, the keys in Table 2 correspond to the commands in Table 1 according to their relative positions in the table. For example, the command List is mapped to Key “1,” which is to the left of Key “2” and above Key “4.” Therefore, the command List (or a symbol representing the command) would be displayed to the left of Guide, the command mapping Key “2,” and above Rew, the command mapping Key “4.”
In another embodiment, rather than displaying commands in positions mapping the positions of the assigned keys, the commands can be displayed next to representations of the associated keys. One example of this arrangement is illustrated in

After the system 100 receives 240 the user selection, it can identify the corresponding command and process accordingly. In one embodiment, the corresponding command can trigger a control command on a system separate from the system 100. For example, as set forth above, the system 100 can display video program and/or video stream received from external devices such as place-shifting systems and time-shifting systems. The command selected may correspond to a control command of the place-shifting system streaming the video program to the system 100, such as a switching channel command. The system 100 may transmit the corresponding control command to the place-shifting system. The place-shifting system may interpret the received control command and operate accordingly. Alternatively, the place-shifting system may issue another command for another system (e.g., a set top box). The corresponding control command and the issued command can be transmitted through supported transmission mechanisms, such as infrared transmission, radio frequency transmission, RS-232 transmission, and Internet Protocol transmission.
One skill in the art will recognize that the method described above can be used in a number of circumstances or applications. It can be used with simple file based playback (e.g., where user might want to skip to the next chapter in a video). It can be used in a streaming video service (e.g., where the user might want to quickly select the next video in the service, or perhaps pull up a server based menu of videos to select). It can also be used in the place-shifting scenario, where the user streams video program from another location (e.g., a set top box at home) and can control the source.
Embodiments of the invention provide users of mobile computing devices a mechanism to control video software program by overlaying a menu of commands on the video content being played on the screen. The commands are associated with keys on the device. The commands can be displayed in positions mapping the positions of the associated keys. Alternatively, the commands can be displayed together with an indication of the keys. Users can select a command by triggering the associated key on the device.
