A multimedia authoring server side processor accepts the raw formatted Rich Media Content along with description text file in XML format and outputs the Rich Media, text and graphic components as an edited MVR file in accordance with user's design for execution on a multimedia player.

Description

BACKGROUND OF INVENTION

[0002] 1. Field of Invention

[0003] This invention relates to a multi-media content creation systems, methods and program products. More particularly, the invention relates to textual based authoring systems, methods and program products for creating and managing editable Rich Media Content for application in ebusiness.

[0004] 2. Background Discussion

[0005] Ser. No. 09/268,537 entitled “Framework for Progressive Hierarchical and Adaptive Delivery of Rich Media Presentations and Associated Meta”, filed Mar. 12, 1999 (SE9-98-030), assigned to the assignee as that of present invention and fully incorporated herein by reference, describes a single, easy to use authoring environment, known as HotMedia, for incorporating Rich Media in an ebusiness application. HotMedia lets an author create Rich Media Content, such as video, streaming audio synchronized with images, 3D, animations, panoramas in a single file that can be easily added to a web page. For fast delivery of Rich Media Content on a network, the data contained in a Rich Media file must be in a binary format. However, with a binary format, it is difficult for end users to understand the file structure, add new content or modify the content stored in the file outside the authoring tool. The binary specification also restricts data interchange among applications; open formats and definitions for expansion, and third party tool development. What is needed in the art is a straightforward and easy to understand means of creating and managing Rich Media Content for e-business applications. More specifically, a Rich Media Content creation system and method should include an authoring tool having a vocabulary that defines a media element and specifies the relations between media element; easily created and editable file contents, and enable various raw or compressed media components to be composed using any text editor. The file created by the authoring tool should be ideal for scripting; third party tools; expressing authoring templates; automatic and network authoring processes; multi-stage flow authoring and easy injection of non media (business) information into the file.

SUMMARY OF THE INVENTION

[0006] An object of the invention is a system, method, and program product for creating and managing Rich Media Content for web and other applications in a single, easy to use authoring environment.

[0007] Another object is a system, method and program product for creating and managing an editable Multi Media Vehicle Repository (MVR) file of Rich Media Content in a binary format.

[0008] Another object is a system, method and program product creating textual representation of an MVR file using an Extended Markup Language (XML) format.

[0009] Another object is a system, method and program product for creating an XML based MVR file (MVR-XML) file using any available textual editing tool.

[0010] Another object is a system, method and program product for combining raw media data in an MVR-XML file as a form of data interchange among other Rich Media Contents.

[0011] These and other objects, features and advantages are achieved by combining video, stills, panorama, sound and all forms of media as Rich Media in a Multimedia Vehicle Repository (MVR) file editable with a Rich Media Content description file. The Rich Media Content description file enables users to specify a vocabulary that defines the media elements and relations among the media elements thereby permitting the users to easily create and edit the Rich Media Content and compose various raw or compressed Rich Media components using any text editor. A multimedia authoring server side processor accepts the raw formatted Rich Media Content along with a description text file in XML format and outputs the Rich Media, text and graphic components as an MVR-XML file in accordance with user's design for execution on a multimedia player. The MVR-XML file may be readily altered by modifying the textual specification for the file using any text editor and authoring tool.

DESCRIPTION OF PREFERRED EMBODIMENT

[0017] In FIG. 1, a system 10 receives Rich Media assets 12, typically video, film, sound, panorama, stills or any form of multimedia in a streaming digital format and stores the assets in an authoring server 14 as a Multimedia Vehicle Repository (MVR). The Rich Media assets are stored in the MVR in an uneditable form for conversion into an editable sequence for various applications, e.g. film, advertisement, presentation or other application based upon a textual specification.

[0018] In one embodiment, the textual specification may be prepared using an Extended Markup Language (XML) for describing the combination of Rich Media assets as an application. XML is a set of rules, guidelines and conventions for designing text formats for binary data in a way that produces files that are unambiguous, easy to generate and read by a computer. The guidelines avoid common pitfalls such as lack of extensibility, lack of support for Internet/nationalization and platform dependency. XML is a W3C standard, published February 1998.

[0019] In FIG. 2, the streaming media assets 12 are transmitted in a framework 20 including a file header frame 22, a thumbnail frame 24, a meta frame 26, a media frame 28 and an end of sequence frame 30. The header frame 22 includes a frame header which provides information about the frame size types, flags and frame level. The header frame also includes media information containing definition on different media tracks that may be contained in the file. For general information, the header frame provides the class name of the code that renders immediate type on the client station.

[0020] The thumbnail frame 24 carries a minimalist representation of the information in the framework. For example, if the information carried in the file were a description of merchandize the thumbnail would carry a single image. Thumbnail frame is made possible providing the user a quick introduction to the subject with minimal code and data transfer. The thumbnail frame will also carry parameters producing image pan and animation effects on a single image. A meta frame 26 carries specification of non-media specific information pertaining to enablement of hyperlink actions of media contents and tracking of media interaction.

[0021] Media frames 28 include a frame header and in addition contain media bitstreams initialization data, behavior data and code. The behavior data or initialization data defines the behavior in configuration of a corresponding media player. Media bitstreams data belong to a particular media track and can be carried over multiple frames and these frames can be interleaved with meta frames and frames that belong to other media tracks. Media frames are identified by frame type and track identifier. A frame type and track identifier enables true multiplex delivery for static or dynamic proportioning of various media tracks over limited bandwidth. Media frames can also contain codes that render a media type on the client station. The code in turn can be physically present or could be a URL reference. When present, the code is separated from the file on the server side and thereafter the code data can be made available for on-demand delivery. In the case of a URL reference to code, the code is sent from a remote HTTP server to be similarly made available on demand.

[0022] The end of sequence frame 30 contains 4 frame header and has a marker that signals the end of the entire presentation associated with the file.

[0023] The framework 20 is further described in Ser. No. 09/268,537, supra.

[0024] In FIG. 3, the server 14, typically an IBM Apache web server, includes an operating system 16, typically Windows NT, a textual specification program 18, typically XML and an authoring, typically a HotMedia batch processing program 19 for combining the stored Rich Media assets in accordance with an XML based textual specification. In preparing a textual description of the Rich Media assets as an application, XML makes use of tags and attributes in composing a document. Unlike Hyper Text Markup Language (HTML) which specifies what each tag and attribute means (and often how the text between them will look in a browser), XML uses the tags only to delimit pieces of data and leaves the interpretation of the data completely to the application which reads it.

[0025] The authoring program 19 combines an XML text file and an MVR file as a composed MVR file available for execution on a multimedia player. The program 19 parses and renders XML instructions or tags contained within the XML text edited document. The instructions link the stored Rich Media assets as an application in the MVR file according to the textual specification prepared by a content creator.

[0026] Returning to FIG. 1, a text editing station 27 enables a content creator 29 to download the MVR file of Rich Media assets or an XML based MVR file (MVR-XML) from the server 14. Using any standard text editor, the content creator prepares an XML based textual specification and sends the specification to the server 14 along with the raw media assets or MVR files. The authoring program 19 combines the XML text description file and raw media assets or MVR file to generate a new MVR-XML file, as an application according to the content creator's desires.

[0027] Alternatively, a standard graphical authoring tool 37 may be used by a content creator 39 to assemble and edit the Rich Media assets into an MVR file and return to the server 14. The graphically edited MVR file can be translated into an XML text file or specification by the XML program stored in the server 14.

[0028] Another content creation station 50 may also download the MVR-XML file from the server 14 for re-editing of the XML text file and composing into another MVR-XML file by the authoring program either in the server 14 or in the server 50.

[0029] A client station 52 enables a user 54 to access the server 14 and view a composed MVR-XML file.

[0030] In FIG. 4, a process 400 is described in conjunction with FIGS. 1, 2 and 3 for creating an XML based MVR file, as follows:

[0031] Step 1: An authoring server 14 is activated to load and store an operating system 16, an XML program 18 and an authoring or batch processing program 19.

[0032] Step 2: Rich Media assets 12, i.e. video, stills, sound, etc. are transmitted in digital format and composed and stored in the server as an MVR file.

[0033] Step 3: A text editing station 27 retrieves the MVR file from the server 14 and a content creator 29 using a standard editing tool prepares an XML specification for composing the MVR file into an application.

[0034] Step 4: The content creator 29 returns the MVR file and XML text specification to the server 14.

[0035] Step 5 The server 14 executes the authoring program 18 and combines the XML specification and MVR file into a composed MVR-XML file as an application according to the XML text specification created by the content creator 29.

[0036] Step 6: A graphics authoring station 37 downloads the Rich Media assets and using a standard graphics authoring tool creates a composed MVR file for return to the server 14.

[0037] Step 7: The server 14 using the XML program 18 creates an XML specification for the graphically edited MVR file.

[0038] Step 8: The text or graphically edited MVR-XML file may be transmitted to another content creation station 50 for creating a modified XML specification and a new MVR-XML file when the modified XML specification and MVR-XML file are processed by an authoring tool in the server 14 or 50.

[0039] Step 9: The MVR-XML file is available for modification in stages by other content creator stations creating a modified XML text specification for the MVR-XML file and processing by an authoring tool.

[0040] The invention has been described in a preferred embodiment. Various changes can be made in the embodiment without departing from the spirit and scope of invention, as defined in the appended claims, in which:
