BACKGROUND
This invention relates to software development, and more particularly to content distribution.
It can be difficult for content publishers to create engaging experiences for new mobile phones and other consumer electronics devices since such devices typically have proprietary hardware interfaces and lack mature software development tools. Moreover, content developed for one device may not be compatible with other devices. To overcome this issue, content publishers may need to create custom presentation software for each device to which they publish content. However, this makes publishing content to different devices cumbersome at best.

DETAILED DESCRIPTION
FIG. 1 is a schematic diagram 100 of the creation and distribution of an application program 102b created for the Binary Runtime Environment for Wireless (BREW), available from Qualcomm Incorporated of San Diego, Calif. BREW is an application development platform created by Qualcomm for wireless devices. The wireless device 112, hereafter referred to as a “client”, can be a cellular phone, a personal digital assistant (PDA), a Blackberry, a laptop computer, a Pocket PC, an electronic gaming device, a media player, or combinations of these. In some implementations, the client 112 does not have wireless connectivity. An advantage of the BREW platform is that it hides specifics of the underlying device from applications which allows applications to be easily ported to different devices.
A so-called “escort” application program (e.g., 102b) encapsulates a document (e.g., 104) such as, for example, an Adobe Flash document, and enables the document to be downloaded to and presented on clients that support BREW (e.g., 112). Flash and Flash Player are available from Adobe Systems Incorporated of San Jose, Calif. Adobe Flash is an Integrated Development Environment (IDE) for developing Flash documents that support, for instance, rich content, user interfaces, and web applications. Adobe Flash Player is a multiple-platform virtual machine used to present Flash documents. Flash is commonly used to create interactive web page content such as advertisements, integrate video into web pages, and create rich, client-side applications, for example.
A BREW system includes a set of Application Programming Interfaces (APIs) 106 for running software on clients (e.g., 112). The APIs 106 allow application software (e.g., 102b) to be independent of client's native software 114. The BREW APIs 106 provide applications access to a client's communication systems, input systems (e.g., microphones, cameras), and output systems (e.g., displays, speakers). Moreover, the BREW APIs 106 also allow applications to take advantage of an automatic billing model which can automatically charge a user for downloading an application or parts of an application, running an application, or combinations of these.
To create the escort application 102b, a software developer 108 first creates or identifies a document 104 for presentation on the client device 112. The document 104 can include text, graphics, sound, animation, other multimedia content, and combinations of these. The document 104 is not limited to a particular content format and can contain interactive content. For example, the document 104 can be formatted as a Shockwave (from Adobe Systems Incorporated), Portable Document Format (PDF), Flash, Flash Lite (from Adobe Systems Incorporated), a sound or music file, an electronic game executable, a movie or animation file, or graphic file, etc. The document 104 can additionally be compressed, encrypted or both.
The developer 108 uses a software development tool to combine a document loader portion 102a with the document 104 to create the BREW escort application 102b. The document loader portion 102a is a BREW application. In some implementations, the software development tool can insert the document 104 contents into a data segment of the document loader portion 102a. The new escort application 102b can be uploaded to a BREW Distribution System (BDS) as an item within a BDS catalog 110. The BDS catalog 110 is a system in which BREW applications are made available over a wireless service provider to end users through a wireless service provider's Application Download Server (ADS). A wireless service provider, also known as a wireless carrier, mobile phone operator, or cellular provider, is a company that provides communication services for its subscribers' wireless devices.
A client user can browse a wireless service provider's ADS to locate BREW applications available within the BDS catalog 110, such as the escort application 102b, for download to the client 112. Once the escort application 102b is downloaded to the client 112, a user can choose to execute the escort application 102b or the escort application 102b can automatically execute. Execution of the escort application 102b causes execution of the document loader portion 102a which, in turn, causes presentation of the document 104 on the client 112, as will be described in more detail below.
FIG. 2 illustrates a flow chart of a method 200 for the creation and distribution of an escort application (e.g., 102b). A document (e.g., 104) is identified for eventual presentation on a client (e.g., 112; step 202). For example, the document can be a Flash document or a PDF document. A document loader portion (e.g., 102a) is identified which contains instructions capable of causing presentation of the document on a client (e.g. 112; step 204). In some implementations, the document loader portion is specific to the type of document. In addition, the document loader portion can be specific to the type of client user billing desired (e.g. pay-per-download, pay-per-play, etc.).
The document and the document loader portion are then incorporated into an escort application (e.g. 102b; step 206). A software development tool, for example a compiler product, can bundle a document with a document loader into an escort application. The development tool can also compress and/or encrypt the document. The escort application is then published in an application catalog such as the BDS catalog, for example (step 208). This makes the escort application available to users for downloading into their clients. In some implementations, a client device's wireless service provider provides client access to the catalog and facilitates downloading of the escort application from its servers.
FIG. 3 is a schematic diagram 300 illustrating the execution of an escort application. The client 112 can communicate with a wireless service provider network 304 in order to communicate with other clients, such as by sending/receiving instant messages and placing/receiving telephone calls, for example. Additionally, the client 112 can download applications (e.g., escort applications) selected from the BDS catalog 110, or other catalog, by way of the wireless service provider network 304, for example. The server 302 provides access to BREW applications stored in the catalog 110.
The escort application 102b is dependent on one or more external modules which are needed to present the document 104. An external module is compiled separately from the escort application 102b. In some implementations, an external module is a BREW extension. Extensions are module software that can be downloaded once and shared by a number of applications, similar to Dynamic Link Libraries (DLL) in the Microsoft Windows and Unix operating systems. During or after the escort application 102b has been downloaded to the client 112, one or more external modules (e.g., 306 and 308) which are needed by the escort application 102b are automatically downloaded from a server (e.g., 302) by the BREW system if they are have not already been downloaded.
The escort application 102b can begin to execute automatically after the download process has completed, or the escort application 102b can be explicitly invoked by the user. The escort application 102b interacts with the public extension 308 by way of one or more APIs, for example, to cause the public extension 308 to present the document 104 bundled within the escort application 102b. For example, a public extension 308 API function call could take as arguments the location of the document 104 within the escort application 102b, the document 104's type, the document's 104 length, and other suitable parameters. With this information, the public extension 308 can obtain and present the document 104, such as by providing the document or a reference to the document to a Flash player or a PDF viewer.
In some implementations, the means for presenting the document 104 is incorporated into the public extension 308. In other implementations, the means is incorporated into a private extension 306 so that the escort application 102 does not interact directly with the private extension 306. Instead, the public extension 308 interacts with the private extension 306 on behalf of the escort application 102b. The private extension 306 can include a fine level of granularity in its API which can be taken advantage of by the public extension 308 for controlling the presentation of the document 104. The private extension 306 API can be hidden from applications such that, in some implementations, only through the public extension 308 can an application interact with the private extension 306. This has the advantage of providing a simpler API to applications by hiding more complex APIs behind the public extension 308.
FIG. 4A is a flow chart of a method 400 for the execution of an escort application. The client (e.g., 112) identifies an escort application for execution (e.g., 102b; step 402). For example, such identification can be caused by a user invoking the escort application from a graphical user interface on the client. The client executes the executable portion of the escort application (e.g., 102a; step 404). The escort application signals an external module capable (e.g., 308) capable of causing presentation of the document portion of the BREW application (step 406). The document (e.g., 104) is then presented on the client.
FIG. 4B is another flow chart of a method 400 for the execution of an escort application. A BREW application containing a document is received (e.g., by a client; step 403). An external module (e.g., 306, 308) is received (step 405). The application is then executed, where the execution causes presentation of the document by signaling the received external module (step 407). An account associated with the client is debited or credited based on the first receiving, the second receiving, the executing or the signaling (step 409).
A revenue generation system is built into the BREW environment that allows an account to be automatically charged for downloading files, executing applications, or combinations of these, according to a billing model. In one implementation, the BREW application performs calls to one or more BREW extensions to verify access to the application. For example, a previously downloaded application can require additional payment in order to run because the monthly license for content access has expired. In this circumstance, a BREW extension can be used to enact a debit to the user's wireless service provider service account. In another implementation, a BREW extension can be used to trigger a credit to a user's wireless service provider service account.
FIG. 5 is a schematic diagram of a generic client 500, such as a cell phone, a smart phone, an electronic game device, a personal digital assistance, a digital media player, other devices, and combinations of these. The system 500 can be used for practicing operations described in association with the flow diagrams 400 and 401. The system 500 can include a processor 510, a memory 520, a storage device 530, and input/output devices 540. Each of the components 510, 520, 530, and 540 are interconnected using a system bus 550. The processor 510 is capable of processing instructions for execution within the system 500. Such executed instructions can implement one or more components of system 300, for example. In one implementation, the processor 510 is a single-threaded processor. In another implementation, the processor 510 is a multithreaded processor. The processor 510 is capable of processing instructions stored in the memory 520 or on the storage device 530 to display graphical information for a user interface on the input/output device 540.
The memory 520 is a computer readable medium such as volatile or non volatile that stores information within the system 500. The memory 520 could store data structures representing one or more applications 102b, a private extension 306 and a public extension 308, for example. The storage device 530 is capable of providing persistent storage for the system 500. The storage device 530 can be a floppy disk device, a hard disk device, an optical disk device, a flash drive, or a tape device, or other suitable persistent storage means. The input/output devices 540 provide input/output operations for the system 500. In one implementation, the input/output device 540 includes a keyboard, stylus and/or pointing device. In another implementation, the input/output device 540 includes a display unit for displaying graphical user interfaces.
The input/output device 540 can provide input/output operations for the application 102b. The application 102b can be, for example, an application containing a document 104 formatted in Shockwave, Portable Document Format (PDF), Flash or Flash Lite document format available from Adobe Systems, Incorporated of San Jose, Calif., or another document format or executable format for presentation on a wireless device. The BREW application can include external modules required for its presentation. Examples of such external module software components include private extension 306 and public extension 308. BREW APIs 106 provide translation between the BREW application 102 software and the device-specific software 114 such as the software used for accessing the input/output device 540. Such software components 102, 104, 106, 306, and 308 can be persisted in storage device 530, memory 520 or can be obtained over a network connection, to name a few examples.

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for performing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto-optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio player, a Global Positioning System (GPS) receiver, to name just a few. Computer-readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.
