1. Technical Field
The present invention relates to a system for displaying images to a user and, more particularly, to a system compositing images from multiple, different applications.
2. Related Art
Devices that display images are used in a wide range of applications. MP3 players may display images of an artist and/or album artwork associated with its stored media content. Video players may display streaming video from a memory storage device, a private network, and/or the Internet. Cellular phones may display streaming video from a memory storage device, a private network, the Internet, and/or another cellular phone subscriber.
The user may be provided with an interface for interacting with the device. The interface may include a hardwired interface and/or a virtual interface. Hardwired interfaces may include pushbutton switches, rotary switches/potentiometers, sliders, and other mechanical based items. Virtual interfaces may be implemented using virtual buttons, virtual sliders, virtual rotator controls, function identifiers, and other visual elements on a display, such as a touchscreen display. In a combined interface, function identifiers may be placed on a display adjacent corresponding mechanical based items, such as switches.
The development of a virtual interface and/or display may become complicated when the interface must display an image and/or images from different applications. Still images and/or video images may be integrated with one another in a single application package for playback. This approach, however, limits still images and/or video playback to the images and/or video integrated within the application. Other approaches to combining images and/or video images may be complicated and require extensive use of a non-standard virtual interface development environment.
A system compositing images from different applications includes a movie clip based application, an image application, and a compositing application that is in communication with the movie clip based application and the image application. The movie clip based application defines one or more movie clip images for display. The image application provides one or more images for display with the one or more movie clip images. The compositing application operates to composite the one or more movie clip images with the one or more images of the image application for viewing on a display.

System 100 includes a processor 103 that may interface with memory storage 105. Memory storage may include a movie clip based application 107 and an image application 110. Movie clip based application 107 is executable by the processor 103 and may be used to determine how a user interacts with system 100 through user interface 113. User interface 113 may include a display 115, such as a touchscreen display, and/or mechanical controls 117.
The processor 103 may interface with various image sources 135 that may be controlled by an image application 110. The image application 110 is executable by the processor 103 and may receive image information from the various image sources 135 for display on display 115. In
The movie clip based application 107 and image application 110 may communicate with a compositing application 150 that composites one or more movie clip images of the movie clip based application 107 with one or more images of the image application 110 on display 115. The compositing application may include one or more image decoders 130, such as a DVD decoder. The compositing application 150 may show an image from the image application 110 in a masked region defined by the movie clip based application 107 based on a masking criterion. The masked region may correspond to a movie clip having a defined masking criterion. Various masking criterion may be used. System 100 may use the alpha channel value of an image in the masked region and/or the chromakey channel value of an image in the masked region. Additionally, or in the alternative, the compositing application 150 may composite movie clip images with images from the image application 110 using compositing information defined by the movie clip based application 107 and/or the image application 110.
The movie clip based application 107 may provide information corresponding to the images for movie clip based controls to a movie clip application interface 205 of the compositing application 150. This information may include the memory location(s) in image memory 207 at which the various movie clip images are stored. The compositing application 150 may access these images from memory storage and display the controls in the manner dictated by the movie clip based application 107 on display 115. In
The display 115 includes an image display area 245 for displaying images provided by the image application 110. The image display area 245 may correspond to a masked display region that may be defined by the movie clip based application 107. Image display area 245 may be a movie based clip having characteristics corresponding to the masking. For example, image display area 245 may have a color corresponding to a chromakey color mask. The image display area 230 may be a solid color, such as green or blue, although other colors may also be used. Additionally, or in the alternative, image display area 230 may have an alpha channel value corresponding to a mask.
The image application 110 may provide information corresponding to the images that are to be composited with the movie clip based controls through an image application interface 250 of the compositing application 150. This information may include the memory location(s) in image memory 207 at which the images are stored. The compositing application 150 may access these images from memory storage and use a composition processing module 255 to display the images in the manner dictated by the movie clip based application 107 on display 115. In
The movie clip based application 107 and image application 110 may interact with one another through the compositing application 150. Manipulation of a control 210, 215, 220, 225, and/or 235 may be detected by the movie clip based application 107. movie clip based application 107 may also interpret the manipulation and communicate this interpretation to the compositing application 150 for further communication to the image application 110. In response, the image application 110 may execute a corresponding operation. Additionally, or in the alternative, the image application 110 may interpret the manipulation provided by the movie clip based application 107.
The image application 110 and image type provided for display in image display area 245 may vary depending on image source 135. For example, image application 110 may include a DVD interface application that provides DVD video from a DVD player 145 (
The user interface 113 may be readily changed by playing back a different FLASH® file 310. This functionality may be used to change the user interface 113 in response to changes in the image source 135 and/or image application 110. When the image source 135 is a DVD player, a FLASH® file 310 having controls corresponding to a DVD player may be used to generate the user interface 113. Controls 210, 215, 220, 225, and/or 235 may correspond to such functions as play, rewind, forward, reverse, volume, and other DVD player functions. When a control is manipulated by a user, its function may be interpreted by the FLASH® player 305. The FLASH® player 305 may notify the image application 110 of the function request, either directly or through the compositing application 150. The image application 110 may either execute the requested function or deny its execution. If denied, the FLASH® player 305 may provide an indication of the denial to the user based on the programming in the FLASH® file 310.

Additionally, the application loader 710 may dispatch the following events:
A movie clip application server 725 is used to communicate with a corresponding operating system server 730 included as one of a plurality of operating system components 735. The movie clip application server 725 is also in communication with one or more component handlers associated with applications 715 and 720. The component handlers may be responsible for communicating commands and handling events associated with corresponding operating system components. In
The DVD component 755 may control a DVD player that runs as a stand-alone application in the operating system. It may be used to display DVD video at a certain screen position that may be defined by application 715 through DVD handler 750. Additionally, the DVD component 755 may respond to DVD player commands (e.g., play, fast-forward, reverse, volume, forward chapter, reverse chapter, or other command) provided by application 715 through DVD handler 750.
Application 720 may include a multimedia engine (MME) handler 760 for communicating commands and handling events associated with a multimedia engine (MME) component 765 of the operating system. This MME component 765 may be used to control multimedia middleware to perform various multimedia functions. MME components 765 may be used to position media thumbnails on a display based on commands received from application 720 through MME handler 760. Other functions include acquiring a device list, song/album list, audio playback, playback zone selection, and other multimedia functions.
The component handlers of the core application 705 are attached for communication with the movie clip application server 725. The following code may be used in attaching the handlers shown in
Web Handler Example
MME Handler Example
DVD Handler Example
With the handlers attached to the movie clip application server 725, applications 715 and 720 may communicate with the corresponding components of the operating system. In
Communications between the movie clip application server 725 and the operating system application server 730 may be based on an XML protocol. The communications from the movie clip application server 725 to the operating system server 730 may have the following format:
In this format, the component_name may identify the target component for the message. The xml string between <qcomp> . . . </qcomp> may be passed to the component for processing. The type and action may be used to identify the command that the component is to perform. For example, the MME handler 760 may send <t>trace</t><a>list</a> to the movie clip application server 725 which, in turn, incorporates this type and action into the XML protocol format for transmission to the operating system server 730. The operating system server 730 may strip any unneeded information from the transmission before the information is sent to MME component 765 for execution. The <arg0> . . . </argN> between <p> and </p> may be used to pass arguments to a component for processing.
The movie clip application server 725 may send one message at a time to the operating system server 730. It may wait for an acknowledgment from the operating system server 730 before sending another message. The acknowledgment from the operating system server 730 may have the following format;
<qcomp><ack></ack></qcomp>
A component may send a message back to the corresponding handler using communications from the operating system server 730 to the movie clip application server 725 over link 770. The message may include data, an event, or similar information. Communications from the operating system server 730 to the movie clip application server 725 may have the following format:
The MME component 765 may send the following event to the movie clip application server 725, to indicate a track session id:
The communications over link 770 may include various types of information specific to the various components and their corresponding handlers. In compositing images, the location of a webpage on a display may be dictated by the application 715 to the web component 745 using communications from web handler 740. The location of DVD video on a display may be dictated by the application 715 to the DVD component 755 using communications from web handler 750.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the invention.
