SWF to HTML Cross-Compiler Using Intermediate Format
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in playing SWF content on portable devices due to performance issues and limited support for SWF format on mobile platforms, with existing conversion methods like direct compilation to SVG or interpretation by JavaScript being computationally intensive and inefficient.
Innovation Solution
A data processing apparatus and method that uses a Cross-Compiler to convert SWF files into an intermediate format, which is then rendered using Scalable Vector Graphics (SVG) and HTML5 by an Intermediate-Code Runtime, distributing computational tasks effectively between server and client and optimizing multimedia content rendering on devices with limited resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SWF files are directly compiled into SVG and JavaScript, then the content can be rendered on mobile platforms, but the computational load is placed on the client and performance is degraded
Solution Approach 1:
The conversion process is segmented into two distinct phases: server-side compilation where the SWF file is converted to an intermediate format, and client-side rendering where the intermediate format is processed to generate final SVG and JavaScript output. This segmentation moves the computationally intensive compilation task from the client to the server, improving mobile platform compatibility while maintaining rendering performance.
Solution Approach 2:
An intermediate format is introduced as a mediator between the SWF source format and the target SVG/JavaScript output. This intermediate representation enables efficient conversion on the server side while allowing lightweight rendering on mobile devices, thus resolving the contradiction between adaptability and productivity.
2Adaptability or versatility
If SWF files are interpreted using JavaScript in the browser, then cross-platform compatibility is achieved, but complex transformations like video and audio recoding must be performed every time a user visits the page
Solution Approach 1:
The SWF file is compiled into the intermediate format in advance on the server side before the user accesses it. This preliminary compilation action eliminates the need for complex transformations to be performed repeatedly in the browser on each page load, significantly reducing transformation time while maintaining cross-platform compatibility.
Solution Approach 2:
The intermediate format serves as a pre-processed mediator that contains the compiled representation of the SWF content. By using this intermediate format, the system achieves cross-platform compatibility without requiring time-consuming real-time transformations, as the heavy lifting is already done during the preliminary server-side compilation.
3Productivity
If a cross-compiler is used to convert SWF to intermediate format on the server, then computational load is reduced on the client, but the device complexity increases
Solution Approach 1:
The intermediate format acts as a mediator that simplifies the client-side requirements while consolidating complexity on the server side. The server-based cross-compiler handles the complex conversion tasks, reducing computational load on mobile devices while the intermediate format provides a standardized interface that manages the complexity of the compilation system.

AI summary
A data processing apparatus (300) and method are described for rendering multimedia content for hierarchical structured documents, including a cross-compiler (308) that parses a formatted multimedia object (306), performs conversions on video data and audio data contained in the formatted object, and generates an intermediate object (310) representing the data from the formatted multimedia object (306), and a runtime-script that receives the intermediate object (802, 310) and dynamically generates and modifies scaleable vector graphic nodes in a hierarchical structured document (804) for rendering of the multimedia content by a web browser (806, 312).
