Adobe Flash Lite is a lightweight version of Adobe Flash Player, a software application published by Adobe Systems. This version is intended for mobile phones and other non-phone, portable electronic devices like Chumby and iRiver, and allows users of these devices to view multimedia content and applications developed using Adobe's Flash tools, which had previously been available only on personal computers. Adobe Flash Lite is a development technology implemented at the client-side, or user interface layer, . In this realm Flash Lite competes with other technologies like Qualcomm's uiOne markup language and Sun Microsystems's JavaFX Script. Recent changes to ActionScript allow Flash Lite to better integrate with and even compete with device-layer technologies like Java ME and BREW. Flash Lite should not be considered a mobile operating system like Symbian OS, Windows Mobile, Mac OS X for mobile: it is a technology for developing applications that run on a mobile operating system. Adobe Flash Lite 1.1 supports Flash 4 ActionScript. Flash Lite 2.0, based on Flash Player 7, supports Flash 7's newer ActionScript 2.0. Both versions also support the World Wide Web Consortium's Standard SVG Tiny, a mobile profile of the consortium's Scalable Vector Graphics (SVG) recommendation. Unlike SVG, Flash Lite can add audio and interactive elements without the use of other technologies such as JavaScript. As with Flash, Flash Lite is able to read and redraw external XML content. Flash Lite 3 is based on Flash 8, which brings closer the gap between mobile and desktop content by supporting H.264 video standard, as well as On2 VP6 and Sorenson video codecs. It also introduces the support to FLV video content.
