Streaming specification

The Internet Streaming Media Alliance has released details of Version 1 of its Encryption and Authentication Specification, a content protection specification that provides a framework for secure content delivery over IP networks.

The Internet Streaming Media Alliance (ISMA) has released details of Version 1 of its Encryption and Authentication Specification, a content protection specification that provides a framework for secure content delivery over Internet Protocol (IP) networks.

It builds upon the existing core ISMA Specification 1.0 released in 2001, which provides an end-to-end implementation for interoperable streaming of video and audio content over IP networks.

ISMA Encryption and Authentication 1.0 is player- and device-type independent, making playback to a host of devices, such as desktop computers, tablets, set-top boxes, media servers, mobile devices, and personal digital assistants, possible.

The AES 128-bit algorithm is the chosen default encryption mechanism that has been chosen, but stronger encryption can be added if necessary.

Both the ISMA Encryption and Authentication Specification v.1.0 and ISMA Specification 1.0 are available for download on ISMA’s website <a href=’http://www.isma.tv/resources/techspecs’>here</a>.
