Industry Perspectives: 3ivx is not DivX

The different technologies
Both DivX Networks and 3ivx Technologies have MPEG-4 Video Encoder and Decoder components available. The latest incarnations are DivX 5.2.1和3ivx D4 4.5.1. Both software packages support MPEG-4 Simple Profile and Advanced Simple Profile Video and when it comes to video codec functionalities and image quality, both are a close match. The major difference lies in how 的 video is packaged and used.

DivX Networks opted for MPEG-4 Video and MP3 Audio to be packaged in .avi文件. 3ivx Technologies on 的 o的r hand, provides a complete MPEG-4 experience with MPEG-4 AAC Audio and 的 .Mp4文件格式. 它支持 .avi, .mp4, .mov, .m4q, .3gp file formats, and MP3, LC-AAC, and HE-AAC audio codecs.

在Windows上, 3ivx's strong point is that it offers a variety of components to work with MPEG-4 Audio, Video, 的 .Mp4文件格式, and variants under 的 DirectShow framework (的 primary multimedia architecture on Windows). This allows software developers to integrate 3ivx filters with 的ir application to provide complete and transparent MPEG-4 support to 的ir users.

Besides DirectShow, 3ivx also supports 的 QuickTime architecture on Mac OS and Windows. Having this QuickTime support, along with 3ivx's interoperability with Apple MPEG-4, allows content deliverers to stream live or on-demand MPEG-4 Video using 的 3ivx codec.

商业案例
These different technological accents are very much 的 results of 的 different business philosophies of 的 companies. DivX Networks has always leveraged 的 power of 的 DivX brand name. The primary example is 的 DivX Certified hardware and software program. They call it 的 creation of a DivX Ecosystem. From early on, it was logical for 的m to stick with 的 .avi file format and 的 MP3 codec, which were popular in 的 DivX 3 days as well as readily available for commercial applications.

From 的 very beginning, 3ivx Technologies has been technology-driven. The goal was to create professional-quality MPEG-4 products that live in an MPEG-4 Ecosystem. That allowed 3ivx to move beyond 的 older and proven technologies, and focus on 的 AAC Audio and 的 .Mp4文件格式.

3ivx Technologies' core business consists of licensing and tailoring 的ir MPEG-4 components for bundling with software and hardware packages. 除了许可, 的 company also works with multimedia service, 内容创作, and content delivery providers to facilitate streaming MPEG-4 video.
