Adobe says it's going to publish the Real-Time Messaging Protocol (RTMP) specification designed for high-performance transmission of audio, video and data between Adobe Flash Platform technologies.

Think AMF, SWF, FLV and F4V formats compatible with Adobe Flash Player.

The RTMP disclosure will be the latest advance of the so-called Open Screen Project, an industry-wide initiative to enable the delivery of rich multi-screen experiences built on a consistent runtime environment for web browsing and standalone applications across PCs, mobile devices and consumer electronics taking advantage of Adobe Flash Player and, in the future, Adobe AIR.

For customers who want to protect their content, Adobe said the open RTMP specification won't include its secure RTMP measures, nor will the license that accompanies the specification allow developers to circumvent such measures.

However, developers will be free to use their own technological measures to secure content. The RTMP specification does not provide any requirement or restrictions on a developer's own measures to secure content.

The spec should be posted at www.adobe.com/devnet/rtmp sometime this half.
